Jack in the Box Breakfast Sandwiches: Calories, Protein, Price & Allergens (2026)

The Breakfast Jack is 410 calories, with 16 g of protein and 1,180 mg of sodium, according to the brand’s 2026 nutrition PDF. The Supreme Croissant is 790 and the Sourdough Breakfast Sandwich is 810. The label shows the sandwich you pick below, next to an estimated price and the allergens the brand lists. One sandwich row, the Extreme Sausage, prints values that look wrong, so we show it as printed and keep it out of the rankings.

Breakfast sandwiches ranked by calories, protein, sodium and cholesterol

These charts rank 8 of the 9 sandwiches. The Extreme Sausage Sandwich is left out because its printed row looks wrong (see what we found), and ranking it would put a questionable figure at the top or bottom of every list. All amounts are the brand’s published values for one sandwich.

“Lowest or best” means the smallest amount for calories, sodium, cholesterol and saturated fat, and the largest for protein. It is arithmetic on published amounts, not a health rating. Percentages use the FDA Daily Values of 2,300 mg sodium, 300 mg cholesterol and 20 g saturated fat.

The three Breakfast Jacks

The plain Breakfast Jack is 410 calories. The bacon version is 30 calories lower at 380, so bacon does not add calories on this label, and the PDF does not say why. The Sausage Breakfast Jack is 620, which is 240 more than the bacon version. The PDF does not say how the fillings differ, so we cannot explain the gap.

The croissants

The Supreme Croissant is 790 calories, 1.9 times the Breakfast Jack, with 2.4 times the protein. The Sausage Croissant is 710, so the Supreme is 80 calories more and its sodium is lower (1,500 mg against 1,690 mg).

Sourdough, Ultimate and Loaded

The Sourdough Breakfast Sandwich lists 810 calories and 40 g of protein for 311 g. The Ultimate Breakfast Sandwich is 510 calories, and the Loaded Breakfast Sandwich is 180 more at 690. The best protein-to-calorie ratio of the 8 is the Ultimate Breakfast Sandwich: 5.7 g per 100 calories.

Sandwiches differ in weight, so check the serving row before comparing totals. Dollar differences are left out on purpose, because prices are estimates that vary by restaurant.

What the brand says is in them

What is in a Jack in the Box breakfast sandwich? Bread, egg, meat and cheese

The brand’s Ingredient & Allergen Statements 2026 document prints ingredient statements per component (bun, egg, sausage and so on), not per menu item, and it gives no percentages. Below is a plain-English reading, then the statements word for word.

The bread

The regular bun has 2 printed versions, and one of them lists sesame flour, and the statement says it is toasted with butter flavored vegetable oil. The croissant statement lists margarine and non-fat dry milk. The grilled sourdough bread has 4 printed versions and is grilled with butter flavored vegetable oil.

The egg and the meat

The fried egg statement is a single ingredient, a USDA Grade AA medium egg, grilled with butter flavored vegetable oil. Scrambled eggs have 2 printed versions. The sausage patty has 3 printed versions, and every one of them starts with pork. The bacon statement lists sodium nitrite, a curing ingredient. The ham statement also lists sodium nitrite and says 35% of its weight is added ingredients.

Which sandwich uses which egg, meat or cheese is not in the PDF, so we do not claim it. The drawings add a sausage patty or bacon strips only when a sandwich’s name says so.

Buns, croissant and sourdough

The brand prints one statement per bread, and some have several versions that vary by region.

Allergens and diet

Jack in the Box breakfast sandwich allergens: milk, egg, wheat and soy

“Contains” here is the union of the brand’s nutrition PDF and its Allergens Reference Guide, so if either document lists an allergen, it is shown. A blank means neither lists it, which is not the same as a promise that it is absent.

What this means

Every one of the 9 sandwiches lists milk, egg, wheat and soy, so none works if you avoid them.
Sesame is listed on 6 of 9 sandwiches. The ones that do not list it are Supreme Croissant, Sausage Croissant and Sourdough Breakfast Sandwich. But the brand’s ingredient statement for the regular bun has 2 versions and one of them includes sesame flour, so ask about the bun if sesame matters to you.
Sourdough Breakfast Sandwich appears in the nutrition PDF only, so there is no second document to cross-check.
None of the 9 sandwiches lists fish, peanuts, tree nuts and crustacean shellfish.
The brand’s documents make no gluten-free, dairy-free or vegan claim for any breakfast sandwich.

Where the two documents disagree

Breakfast Jack: the Allergens Reference Guide adds sesame.
Sausage Breakfast Jack: the Allergens Reference Guide adds sesame.
Loaded Breakfast Sandwich: the nutrition PDF adds sesame.
Extreme Sausage Sandwich: the Allergens Reference Guide adds egg and sesame.

We show the union, so a sandwich lists an allergen if either document does. We cannot say which document is right.

The brand’s own cross-contact notice

“Like most restaurants, Jack in the Box restaurants prepare and serve products that contain Soy, Egg, Fish, Milk, Wheat, and Sesame. While a particular ingredient statement may not list one of these allergens, products may be prepared with equipment that is shared with products containing one or more of these allergens. If you have a food allergy, please consult with your physician before deciding which Jack in the Box products are right for you, and check the allergen information frequently as the menu and ingredients may change.”

Quoted from the Allergens Reference Guide. Ask the restaurant about your allergy before you order.

Price

How much do Jack in the Box breakfast sandwiches cost?

Price varies by location. Jack in the Box does not publish national menu prices, and restaurants, many of them franchises, set their own. This is an estimate, not a quote: the median pickup price from Drive Thru Index (opens in a new tab)’s sample of 2,065 to 2,075 restaurants as of November 11, 2026, with the lowest and highest the sample found.

Estimated lowest, typical and highest pickup price for each Jack in the Box breakfast sandwich
Sandwich	Lowest	Typical	Highest	Restaurants
Breakfast Jack	$1.99	$3.49	$4.29	2,067
Bacon Breakfast Jack	$2.39	$3.79	$5.49	2,066
Sausage Breakfast Jack	$2.39	$3.79	$5.49	2,065
Supreme Croissant	$4.29	$5.49	$7.99	2,067
Sausage Croissant	$3.49	$4.99	$7.79	2,075
Sourdough Breakfast Sandwich	$4.59	$5.99	$8.19	2,067
Ultimate Breakfast Sandwich	$4.79	$5.99	$8.49	2,067
Loaded Breakfast Sandwich	$4.79	$6.29	$8.79	2,066
Extreme Sausage Sandwich	$4.39	$5.50	$8.49	2,065

Cheapest to priciest

The Breakfast Jack is the lowest typical estimate at $3.49 and the Loaded Breakfast Sandwich is the highest at $6.29, a gap of $2.80. Across every restaurant sampled, single prices ran from $1.99 to $8.79.

Value for the money

Among the 8 ranked sandwiches, the Sausage Croissant gives the most protein per dollar (7.2 g) and the Sausage Breakfast Jack the most calories per dollar (164). The Bacon Breakfast Jack gives the least protein per dollar (4.5 g). This is arithmetic on an estimate, so it is only as good as the price you actually pay. There is no per-dollar figure for the Extreme Sausage Sandwich, because its printed nutrition looks wrong.

Why your price may differ

For example, the Loaded Breakfast Sandwich ranged $4.79–$8.79 across the sample. These are pickup prices from the brand’s ordering app, so they are a guide, not what your restaurant will charge. The ordering page for your own restaurant or its menu board has the real price.

When you can order

Breakfast sandwiches all day: when Jack in the Box serves them

The brand's own restaurant pages say it serves its full menu, breakfast included, all day every day. That means the sandwiches above are available whenever your restaurant is open, in the drive-thru or the lobby, but opening times are set by each restaurant.

What the brand says

The statement comes from a restaurant page on the brand’s own site: a Jack in the Box restaurant page (opens in a new tab). It is one restaurant’s page, so treat it as the brand’s own wording rather than a guarantee, and let the Jack app or your restaurant be the final word.

What hours really look like

Of the 24 restaurant pages we reviewed, 16 show a drive-thru open 4:00 AM to 4:00 AM every day and 18 show a lobby that closes earlier than the drive-thru on at least one day. See the opening hours guide for the full breakdown.

Check your restaurant

Individual restaurants, many of them franchises, can run different hours or leave an item off. Use the restaurant finder to open your nearest restaurant’s page, then confirm in the app.

This page covers the 9 breakfast sandwiches. The brand’s breakfast category has 19 items in all, and the rest are classic french toast sticks, classic french toast sticks platter with bacon, classic french toast sticks platter with bacon & sausage, classic french toast sticks platter with sausage, grande sausage burrito (with salsa), grande sausage burrito (no salsa), hash brown, meat lovers breakfast burrito (with salsa) and meat lovers breakfast burrito (no salsa). Their calories are in the nutrition facts tables.

Checking the numbers

Why other sites list different breakfast sandwich calories

Every figure on this page comes from the brand’s 2026 nutrition PDF. We also read 4 other sites. Of 37 calorie figures, 7 match the PDF and 30 differ, by up to 420 calories. For 5 of the 9 sandwiches, the PDF lists more calories than every one of those sites.

Calories for each breakfast sandwich in the brand’s 2026 PDF and on four other websites
Sandwich	2026 PDF	jackintheboxmenunow.com	jackintheboxmenu.net	menuwithnutrition.com	healthyfastfood.org	PDF vs the sites

Extreme Sausage Sandwich	260	650	650	650	660	PDF is lower than every site

A slash means a site lists two figures for the same sandwich. A dash means the site does not list it. The PDF is lower than every site for Extreme Sausage Sandwich, which is the row we flag below.

jackintheboxmenunow.com (opens in a new tab)

Says its figures come from the brand's online ordering page for one Los Angeles restaurant (pickup), checked October 16, 2026. It calls the sourdough sandwich the Supreme Sourdough Breakfast Sandwich.

jackintheboxmenu.net (opens in a new tab)

Says its prices are average estimates, names no restaurant, and is dated March 4, 2026. Its calories are the same as the first site's table. It calls the sourdough sandwich the Supreme Sourdough.

menuwithnutrition.com (opens in a new tab)

Names no restaurant, check date or menu edition. It lists the Sausage Croissant twice, at 550 and 560, in two different parts of the page.

healthyfastfood.org (opens in a new tab)

Names no restaurant, check date or menu edition.

Which number we use

The PDF, everywhere. It is the brand’s own published national nutrition document, we can open it and check it, and it is the only source that also gives fat, sodium, cholesterol, carbs and protein for each sandwich. A restaurant’s ordering page is one location’s view, and we cannot tell from outside why two sources differ. If your restaurant shows a different number, trust what it shows you.

Limits of this comparison

We read these sites' pages on November 10, 2026. Several do not say which menu edition or restaurant their numbers come from, so we cannot tell why they differ from the brand's PDF. The point is to show you the spread, not to rank sites.

We matched sandwiches by name, and where a name could belong to more than one row we did not guess.

Data warning

Extreme Sausage Sandwich: why its printed calories look wrong

The brand’s nutrition PDF prints values for the Extreme Sausage Sandwich that do not fit the rest of the breakfast sandwiches. We show them exactly as printed, keep the row out of every chart, ranking and total, and do not replace them with numbers from anywhere else.

The Extreme Sausage Sandwich as printed compared with the smallest value among the other 8 sandwiches
Measure	As printed	For comparison
Serving weight	68 g	Smallest of the other 8: 123 g
Protein	5 g	Smallest of the other 8: 16 g
Cholesterol	0 mg	Smallest of the other 8: 240 mg
Calories	260	4 other sites list 650 to 660

What this means for you

A sandwich of 68 g with 5 g of protein and 0 mg of cholesterol is unlike the other 8, so we treat the row as suspect and do not call it the lightest.
The PDF's allergen list for it also leaves out egg and sesame, which the Allergens Reference Guide lists. We show the union, so they appear in the allergen table.
We cannot tell which figures are right. Check the sandwich’s label in the Jack app or ask your restaurant before you rely on any of these numbers.

This is our reading of the printed numbers, not a statement from the brand. The same approach is used for the one other row on this site that looks like a printing error. Spot something we got wrong? Tell us on the contact page.

Not in the 2026 PDFs

Biscuit sandwiches and other breakfast listings: reported figures

People search for these sandwiches, and the brand’s 2026 nutrition and allergen PDFs do not list them. So the figures below are reported, not verified: they come from the websites named in each card, with the date and restaurant where the site gives them. They are kept out of the labels, charts, rankings and totals elsewhere on this page, and we show no allergens for them.

Biscuit sandwich, not in the 2026 PDFs

Bacon, Egg & Cheese Biscuit

Listed by three sites as a biscuit with bacon, egg and cheese. The brand's 2026 nutrition PDF has no biscuit sandwich row. Its 2026 ingredient statements do include a "Biscuit, Buttermilk (Regional)", so biscuits may be sold in some regions only, but the PDF does not say where. We show no nutrition, ingredients or allergens for it.

Grilled Sourdough Swiss Sandwich

Listed by two sites as a grilled sourdough sandwich with Swiss cheese (one of them calls it a Grilled Sourdough Breakfast Sandwich). The 2026 nutrition PDF has no row for it, and it is a different sandwich from the Sourdough Breakfast Sandwich above. The brand's ingredient statements list grilled sourdough bread and Swiss cheese separately, but do not say whether this sandwich is sold today. We show no nutrition, ingredients or allergens for it.

Choosing

What to order: breakfast meals, sodium and daily limits

The right pick depends on what you care about most. Everything below is simple arithmetic on the brand’s published amounts, not nutrition advice.

Breakfast meals, added up

Calories, protein and sodium for some Jack in the Box breakfast meals built around a sandwich and a hash brown
Meal	Calories	% of a day	Protein (g)	Sodium (mg)	Sodium %DV
Breakfast Jack and a Hash Brown	600	30%	18	1,530	67%
Bacon Breakfast Jack and a Hash Brown	570	29%	19	1,200	52%
Ultimate Breakfast Sandwich and a Hash Brown	700	35%	31	1,820	79%
Supreme Croissant and a Hash Brown	980	49%	41	1,850	80%

Each meal is the sandwich plus one Hash Brown (190 calories, 350 mg sodium). Add a drink or anything else in the meal calculator to see the full total.

If you want fewer calories

Fewest: Bacon Breakfast Jack, 380 calories, with 17 g of protein. The most is Sourdough Breakfast Sandwich at 810.
The Breakfast Jack is 410 calories, 21% of a 2,000-calorie day.

If sodium matters

The lowest three of the 8 are Bacon Breakfast Jack (850 mg, 37%), Breakfast Jack (1,180 mg, 51%), Sausage Breakfast Jack (1,250 mg, 54%). The FDA treats 20% or more of the 2,300 mg Daily Value in one serving as high.
2 Breakfast Jack sandwiches add up to 103% of the sodium Daily Value, and a Hash Brown on the side adds 350 mg.

If you want protein

The top three by grams are Sourdough Breakfast Sandwich (40 g in 810 calories), Supreme Croissant (39 g in 790 calories), Sausage Croissant (36 g in 710 calories).
For protein per calorie, the Ultimate Breakfast Sandwich leads at 5.7 g per 100 calories.

If cholesterol or allergies matter

6 of the 8 ranked sandwiches list 100% or more of the cholesterol Daily Value on their own, and the lowest is the Breakfast Jack at 80%. Every sandwich lists milk, egg, wheat and soy. Use the allergen chart to filter the whole menu.

FAQ

Jack in the Box breakfast sandwich questions

How many calories are in a Jack in the Box Breakfast Jack?

The Breakfast Jack is 410 calories for 128 g in the brand's 2026 nutrition PDF, with 16g of protein, 25g of fat, 26g of carbohydrate and 1,180 mg of sodium (51% of the Daily Value). That is about 21% of a 2,000-calorie day. Other sites list 280 to 350 calories for it, so we use the brand's PDF and show the comparison further down.

How many calories are in each Jack in the Box breakfast sandwich?

From the brand's 2026 nutrition PDF: Breakfast Jack 410, Bacon Breakfast Jack 380, Sausage Breakfast Jack 620, Supreme Croissant 790, Sausage Croissant 710, Sourdough Breakfast Sandwich 810, Ultimate Breakfast Sandwich 510, Loaded Breakfast Sandwich 690. The Extreme Sausage Sandwich prints 260, but that row looks wrong (see the next question). Sandwiches range from 380 to 810 calories, and other sites often list different numbers, so check the app if the exact figure matters to you.

Why do the Extreme Sausage Sandwich calories look wrong?

The brand's PDF prints 260 calories, a 68 g serving, 5 g of protein and 0 mg of cholesterol for the Extreme Sausage Sandwich. The next-smallest serving among the other 8 sandwiches is 123 g, and 4 other sites list 650 to 660 calories. We show the printed values and keep the row out of every ranking, and we cannot tell which numbers are right, so check the Jack app or ask your restaurant.

Which Jack in the Box breakfast sandwich has the most protein and which has the fewest calories?

Among the 8 ranked sandwiches, Sourdough Breakfast Sandwich has the most protein at 40g (810 calories). Ultimate Breakfast Sandwich gives the most protein for its calories, 5.7 g per 100 calories. Bacon Breakfast Jack has the fewest calories at 380, and Sourdough Breakfast Sandwich the most at 810. The Extreme Sausage Sandwich is left out of these rankings because its printed row looks wrong.

How much sodium and cholesterol are in Jack in the Box breakfast sandwiches?

Sodium runs from 850 mg (Bacon Breakfast Jack, 37% of the 2,300 mg Daily Value) to 1,690 mg (Sausage Croissant, 73%), and 8 of the 8 are 20% or more, which the FDA treats as high. Cholesterol runs from 240 mg to 515 mg against a 300 mg Daily Value, and 6 sandwiches are at 100% or more on their own.

How much do Jack in the Box breakfast sandwiches cost?

Price varies by location, so treat this as an estimate. Across the 2,065 to 2,075 restaurants sampled by Drive Thru Index (pickup prices as of November 11, 2026), typical prices run from $3.49 for the Breakfast Jack to $6.29 for the Loaded Breakfast Sandwich, and single restaurants ranged from $1.99 to $8.79. Restaurants, many of them franchises, set their own prices.

What allergens are in Jack in the Box breakfast sandwiches?

Every breakfast sandwich lists milk, egg, wheat, and soy. Sesame is listed on 6 of 9, and the brand's bun statement has 2 versions, one of which includes sesame flour. The brand's two documents disagree on 4 sandwiches, and we show the union so an allergen appears if either lists it. Shared equipment can mean cross-contact, so ask your restaurant if you have an allergy.

Does Jack in the Box say any breakfast sandwich is vegetarian, vegan or gluten-free?

No. The brand's documents make no vegetarian, vegan or gluten-free claim for any breakfast sandwich, every one lists milk, egg, and wheat, and 4 of the 9 are named for sausage or bacon. If you avoid wheat, milk or egg, none of these works.

What is in a Jack in the Box breakfast sandwich, and is the egg real?

The brand's ingredient statement for the fried egg is a single ingredient: a USDA Grade AA medium egg, grilled with butter flavored vegetable oil, and the scrambled egg has 2 printed versions. The sausage statement starts with pork in all 3 versions. The PDF does not say which sandwich uses which component, so we do not claim a recipe for each one.

Does Jack in the Box have a bacon, egg and cheese biscuit?

The brand's 2026 nutrition PDF has no biscuit sandwich row, so we show no nutrition or allergens for one. 3 sites list a Bacon, Egg & Cheese Biscuit at 410 to 440 calories and a Sausage, Egg & Cheese Biscuit at 530 to 570, and the brand's ingredient statements include a regional buttermilk biscuit. We cannot say whether your restaurant sells one. 2 sites also list a Grilled Sourdough Swiss Sandwich at 580 calories.

Why do other websites list different calories for Jack in the Box breakfast sandwiches?

We compared 37 calorie figures from 4 other sites with the brand's PDF: 7 match and 30 differ, by as much as 420 calories. For 5 of the 9 sandwiches the PDF lists more calories than every one of those sites. Several do not name a restaurant or a menu edition, so we cannot tell why they differ, and we use the brand's PDF.

Can I order a breakfast sandwich in the afternoon or at night?

The brand's own restaurant pages say it serves its full menu, breakfast included, all day every day. Individual restaurants, many of them franchises, can run different hours or leave an item off, so check your restaurant in the Jack app or on its page before you go.

Reference reading

Method and limits

Calories, fat, cholesterol, sodium, carbohydrate, sugars and protein are the brand’s own published amounts for each of the 9 sandwich rows. We do not adjust them. One row, the Extreme Sausage, looks wrong and is shown as printed and left out of rankings.
“% of a day” divides calories by 2,000. Sodium, cholesterol and saturated fat percentages use the U.S. FDA Daily Values of 2,300 mg, 300 mg and 20 g, and are calculated by this site because the brand prints amounts only.
Allergens are the union of the nutrition PDF and the Allergens Reference Guide, which is the cautious reading. If a row is in only one of them, or the two disagree, the page says so.
Prices are estimates from Drive Thru Index’s sample as of November 11, 2026. Ratios such as protein per dollar are arithmetic on those estimates.
Ingredient statements are the brand’s own words. The PDF does not map them to menu items, so any reading of one is our judgment, stated where it is used.
Biscuit sandwiches and the Grilled Sourdough Swiss Sandwich are not in the 2026 PDFs. Reported figures for them come from the named websites, are labelled as reported, and are never mixed into the label, charts or totals.
The sandwich pictures are original illustrations drawn for this site, not photographs of the product.
