White Castle Breakfast Menu 2026: Sliders, Calories, Hours & Deals

White Castle’s breakfast menu looks short on a menu board and turns out to be a small matrix once you order. You pick a bread, a protein and a cheese, and each combination has its own nutrition line in White Castle’s published guide. We went through that guide line by line, so the numbers below are White Castle’s own rather than estimates.

When Does White Castle Serve Breakfast?

White Castle says its breakfast menu is available 24/7. Its January 2026 press release describes breakfast served all day and calls it a 24/7 breakfast menu. That makes it one of the few chains where a Breakfast Slider at midnight is normal. The company ties this to “Night Castle,” its name for late-night business.

There’s one practical limit: a restaurant can only serve breakfast while it’s open, and not every White Castle is open 24 hours. Several hours-tracking sites still print a 10:30 or 11:00 AM breakfast cutoff, but they cite no source and contradict White Castle’s own statement. If you’re heading out overnight, check your restaurant’s hours in the White Castle app or locator first.

How the White Castle Breakfast Menu Works

Every breakfast sandwich starts with a fresh-cracked egg cooked on the grill and a slice of cheese. You then choose the bread, the meat and the cheese. White Castle’s nutrition guide lists each combination separately, which is why the breakfast menu runs to dozens of lines.

Cheese barely moves the numbers. Swapping American for jalapeño or smoked cheddar adds 0 to 10 calories and about 20 to 40 mg of sodium, according to the guide. The tables below use American cheese. The bread and the meat are where the real differences are.

Breakfast Sliders

The Original Slider with Egg & Cheese is a different animal: White Castle’s 100% beef slider, steam-grilled on onions, with an egg added. White Castle’s guide notes that its Original and Cheese Sliders are cooked with onions as standard and can’t be guaranteed onion-free even if you ask for them removed.

Breakfast Toast Sandwiches

The toast doubles the carbs of the slider bun (29 g against 15 g) and adds about 70 calories for the same filling (120 for bacon). Notice the bacon version: at 17 g with American cheese, or 18 g with jalapeño or smoked cheddar, it has the most protein of any breakfast sandwich. It also has the most sodium of any breakfast item: 910 mg, or 940 mg with the other cheeses.

Waffle Breakfast Sliders

The waffles are the indulgent option, and the numbers show it. Each waffle slider carries 14 g of sugar, against 2 g on the bun, and the sausage version is the heaviest breakfast sandwich White Castle makes: 490 calories, 36 g of fat and 15 g of saturated fat. Belgian waffles have come and gone from White Castle over the years, so check that your restaurant has them.

Sides: Hash Round Nibblers® and Waffles

This is the easiest thing to underestimate on the menu. A small order of Hash Round Nibblers has 360 calories, as much as the heaviest Breakfast Slider. Two Waffles with Syrup add 23 g of sugar on their own.

How Much the Bread Changes the Calories

With the same egg, cheese and meat, moving from the slider bun to toast adds about 70 calories (120 for bacon), and moving to waffles adds 130 to 140. That’s the clearest pattern in White Castle’s breakfast numbers, and no menu board spells it out.

Put another way, a plain Egg & Cheese Waffle Breakfast Slider (330) is within 20 calories of a Sausage, Egg & Cheese Breakfast Slider on the bun (350). If you like the waffle taste, the egg-and-cheese waffle is the way to have it without crossing 350.

How Much Is White Castle Breakfast?

White Castle doesn’t publish a national price list. Its one official breakfast price this year was a promotion: two Breakfast Sliders for $4, announced on January 8, 2026 for a limited time. Each slider in that deal came with a choice of sausage or hickory-smoked bacon. The release gave no end date, so check the app for whether it’s still running.

Outside that deal, prices are set by restaurant. Third-party price trackers in 2026 list single Breakfast Sliders anywhere from about $1.99 to $3.29 depending on the build, but they disagree with each other and we couldn’t confirm any of them with White Castle. The White Castle app shows real prices once you pick a restaurant, and it’s also where the company says Craver Nation Rewards members get deals.

Building a Combo: the Real Calorie Math

White Castle doesn’t publish breakfast combo totals, but you can add them up from its guide. A typical pairing is a sandwich plus a small Hash Round Nibblers®:

Drinks are on top of these. A black coffee adds next to nothing; a soda or sweetened coffee doesn’t.

Best White Castle Breakfast Picks by Goal

The lightest breakfast is the Egg & Cheese Breakfast Slider at 200 calories and 370 mg of sodium. The most protein comes from the Bacon, Egg & Cheese Breakfast Toast Sandwich at 17 g (18 g with jalapeño or smoked cheddar). Here’s the pick for each goal, all from White Castle’s own figures.

If two sliders are your usual order, as the $4 deal assumed, two Egg & Cheese Breakfast Sliders come to 400 calories, less than one sausage waffle slider.

Allergens and Vegetarian Options

Every White Castle breakfast sandwich is marked for four allergens in its guide: egg, milk, wheat and soy. The waffle items are also flagged as prepared in a kitchen area or on equipment shared with peanuts. Hash Round Nibblers® contain wheat and share equipment with egg, milk, soy, fish and shellfish.

Vegetarian: the Egg & Cheese versions on the bun, toast or waffles contain no meat. There’s nothing vegan on the breakfast menu, since every sandwich has egg and cheese. White Castle also says all food comes from shared kitchens, so cross-contact is possible for anyone with a serious allergy.

White Castle Breakfast Numbers Other Lists Get Wrong

A widely shared White Castle breakfast list doesn’t match White Castle’s own nutrition guide, and it leaves out half the menu. We checked it item by item.

Because that list’s combo totals are built from these figures, its combo calories are off as well. The combo math above uses White Castle’s numbers.

About White Castle

White Castle calls itself America’s first fast-food hamburger chain, making sliders since 1921. It’s family-owned, based in Columbus, Ohio, and runs about 340 restaurants, according to its 2026 press-release boilerplate. It also makes its own frozen sliders for grocery stores. Fans are “Cravers,” and the company’s app is where Craver Nation Rewards members order pickup and find deals.

Tips for Ordering White Castle Breakfast

White Castle Breakfast vs Other Chains

White Castle is the only burger chain here that says it serves breakfast around the clock. Its sandwiches are also smaller than most rivals’, which is why a two-slider order is normal and why the lightest one comes in at 200 calories.

What to Know Before Your Next White Castle Breakfast

White Castle’s breakfast rewards a little planning. Decide on the bread first, since that sets the baseline, then add meat if you want it, knowing bacon and bologna cost far less than sausage. And if it’s 2 AM, that’s not a problem: White Castle says breakfast is on whenever the doors are.
