Jack in the Box Breakfast Menu 2026: Calories, Hours & Best Picks

Search for the Jack in the Box breakfast menu and you’ll find lists full of breakfast tacos, pancakes and “loaded croissant stacks.” Jack in the Box’s own 2026 nutrition guide has none of them. So we built this page from that guide, item by item, and we’ve marked the few places where even the official numbers look off.

When Does Jack in the Box Serve Breakfast?

All day, every day. Jack in the Box says on its investor site that it serves its full menu, including breakfast, all day every day, and that many locations are open 18 to 24 hours. There is no breakfast cutoff: a Breakfast Jack at 9 PM or a Supreme Croissant at 2 AM is ordinary here.

The only limit is your restaurant’s own opening hours. Not every Jack in the Box is open around the clock, so for a late-night run, check hours in the app or on the restaurant locator first.

The Full Jack in the Box Breakfast Menu

The 2026 guide groups breakfast into sandwiches, burritos, French toast and a hash brown. We’ve split the sandwiches by type below. All figures are Jack in the Box’s per-serving numbers.

Breakfast Jack®

The Breakfast Jack is the chain’s long-running breakfast sandwich and the lightest way to eat breakfast here if you want something hot with an egg in it. Interestingly, the regular version carries more sodium (1,180 mg) than the bacon one (850 mg).

Croissants

The croissants are much heavier than many lists suggest. The Supreme Croissant is 790 calories and 50 g of fat, nearly double the Breakfast Jack. In exchange you get a lot of protein: 39 g, close to the top of the breakfast menu.

Larger Breakfast Sandwiches

The Sourdough Breakfast Sandwich has the most protein of any breakfast item at 40 g. The Ultimate Breakfast Sandwich is the lighter “big” option: 29 g of protein for 510 calories.

*The Extreme Sausage® line looks wrong in the official guide. It lists a 68 g serving with 260 calories, 5 g of protein and 0 mg of cholesterol, which doesn’t fit a sausage sandwich. We’ve reported it as printed, but we’ve left it out of the rankings below. Check the app for this one.

Breakfast Burritos

The two burritos sit at opposite ends. The Grande Sausage Burrito is the heaviest item on the breakfast menu: 1,040 calories, 69 g of fat and up to 1,900 mg of sodium. The Meat Lovers Breakfast Burrito has almost as much protein (36 g against 39 g) for 460 fewer calories. Salsa adds about 120 mg of sodium and no calories to the Grande.

French Toast Sticks and Platters

Three French toast sticks are 230 calories, a reasonable sweet side. The platters change the picture: with bacon and sausage, a French toast platter reaches 780 calories and 1,530 mg of sodium. The guide’s sugar figures for the sticks are modest (6 g for three), but whether that includes syrup isn’t stated.

Hash Brown

A single hash brown is 190 calories, 13 g of fat and 350 mg of sodium, with no major allergens listed. It’s the lightest item in the breakfast section of the guide.

Every Breakfast Item Ranked by Calories

From lightest to heaviest, the breakfast menu runs from a 190-calorie hash brown to the 1,040-calorie Grande Sausage Burrito. The chart shows every item with its protein, so you can see where the calories buy you something.

Best Jack in the Box Breakfast Picks by Goal

For the most protein per calorie, order the Meat Lovers Breakfast Burrito: 36 g of protein for 580 calories. For the lightest sandwich, the Bacon Breakfast Jack at 380 calories. Here’s the pick for each goal, using the official numbers.

Honestly, the Meat Lovers Breakfast Burrito is the standout on this menu. It comes within 3 g of the croissants and the Grande burrito on protein while costing 130 to 460 calories less than any of them.

The Sodium Problem

Most Jack in the Box breakfast sandwiches carry more than half a day’s sodium. The Grande Sausage Burrito with salsa reaches 1,900 mg, about 83% of the 2,300 mg daily value. Six breakfast items are at 1,500 mg or more.

If sodium matters to you, the Bacon Breakfast Jack is the clear choice among the sandwiches. Add a hash brown (350 mg) and you’re still at 1,200 mg, less than most single sandwiches on their own.

Allergens

Almost every breakfast sandwich contains soy, egg, milk and wheat, according to the 2026 guide. Several also contain sesame, and the guide notes that buns contain sesame in some regions.

Vegetarian? The 2026 guide doesn’t label any breakfast item vegetarian or vegan. The French Toast Sticks and the hash brown are the straightforward meat-free choices. Don’t assume the plain Breakfast Jack is meatless; ask at the counter.

How Much Is Jack in the Box Breakfast?

Jack in the Box doesn’t publish a national price list. Prices are set by restaurant and shown in the Jack in the Box app. Third-party trackers in October 2026 listed the Breakfast Jack anywhere from about $2.79 to $3.49, but they disagree and we couldn’t confirm either with the company.

Breakfast deals come and go in the app, and widely shared deal lists are mostly unofficial. The company’s investor site mentions a value lineup called Jack’s Deals, but it doesn’t name breakfast items or prices. For a real price and any current breakfast offer, open the app with your restaurant selected.

Jack in the Box Breakfast Numbers Other Lists Get Wrong

A widely shared Jack in the Box breakfast list doesn’t match the 2026 nutrition guide, and much of what it lists isn’t in the guide at all. We compared it item by item.

The same list includes breakfast tacos, pancakes, biscuits, a “Loaded Croissant Stack,” a “Meat Lovers Platter” and seasonal croissants. None of those appear in Jack in the Box’s 2026 nutrition guide. Limited-time or test items can be missing from a nutrition guide, but a list that leads with them and gets the core items wrong isn’t a reliable menu.

Two Lines in the Official Guide That Don’t Add Up

• Extreme Sausage® Sandwich: listed at 68 g, 260 calories, 5 g protein and 0 mg cholesterol. Those numbers don’t fit a sausage sandwich.
• Meat Lovers Breakfast Burrito (no salsa): the no-salsa row repeats the hash brown’s numbers exactly (190 calories, 2 g protein). The with-salsa row (580 calories, 36 g protein) is the one to use.

We’ve kept both out of our rankings. If either item matters to you, the nutrition shown in the app for your order is the better reference.

About Jack in the Box

Jack in the Box opened in 1951 and is headquartered in San Diego, California, where it was founded. Its investor site describes about 2,100 restaurants in the U.S. and Guam and says roughly 90% of its 500 million annual guests use the drive-thru or take out.
