The Original Slider®

One single White Castle Original Slider costs $1.19 in-restaurant across standard Midwest and Southern markets, and $1.29 to $1.39 in high-rent metro locations such as New York City, New Jersey, and the Orlando, Florida flagship Castle. Ordering a Double Original Slider costs $2.65, while upgrading to a Cheese Slider costs $1.49 (+$0.30).

No, Two single Original Sliders cost $2.38 ($1.19 each) and provide 280 calories, 12g protein, and 26g carbohydrates across two buns. One Double Original Slider costs $2.65 ($0.27 more) because of two pickle slices and assembly, but it eliminates an entire bakery bun—reducing your meal by 20 calories, 120mg sodium, and 11 grams of refined carbohydrates while delivering the identical 12 grams of beef protein.

Each White Castle Original Slider patty weighs 0.88 ounces (25 grams) of raw 100% USDA ground beef before hitting the griddle, meaning 18 raw patties are cut from every pound of beef. After steam-grilling over onions, the cooked beef patty weighs approximately 0.65 ounces (18.4 grams), and the complete assembled slider with bun, onions, and pickle weighs 1.76 ounces (50 grams).

No, The White Castle Original Slider and Double Original Slider are 100% dairy-free and milk-free. Both the 100% USDA beef patty and the signature 2x2-inch bakery bun are formulated without milk, butter, whey, or casein, containing only Wheat and Soy as declared allergens.

No, While kitchen staff can scrape the visible diced onions off the bottom of the patty upon request ('light or no visible onions'), the beef patties and buns are steam-cooked directly over a continuous bed of rehydrated and fresh white onions. Onion vapor and juice permeate the meat and bread during cooking, so an onion-allergy-safe beef slider cannot be guaranteed.

No, White Castle Original Slider patties are made from 100% USDA-inspected beef chuck and round with zero organ meats, zero soy protein extenders, zero chemical binders, and zero added monosodium glutamate (MSG). The patties are seasoned solely with salt and black pepper on the griddle.

A box of 30 Original Sliders at White Castle—officially called a Crave Case—costs $39.99 in 2026, which breaks down to $1.33 per slider and provides 4,200 total calories and 180 grams of protein. Diners can also mix and match Cheese Sliders, Jalapeño Cheese Sliders, or Crispy Chicken Sliders inside a 30-slider Crave Case for a per-slider upcharge of $0.30 to $1.80.

Yes, Customers can order freshly steamed White Castle burgers online for pickup or local delivery via the official Craver Nation mobile app, WhiteCastle.com, DoorDash, Uber Eats, and Grubhub. If you live outside White Castle's 14-state restaurant footprint, you can order frozen 4-packs, 6-packs, 16-pack Crave Cases, and 32-pack boxes online via Instacart, Walmart, Amazon Fresh, and Kroger nationwide.

No, the pickle is not cooked on the griddle. The beef patty, onions, and both halves of the square bakery bun steam together on the 350°F griddle first; immediately before sliding the burger into its cardboard sleeve, the cook places one cold, crisp dill pickle slice underneath the top bun crown so it stays crunchy.

Ordering a White Castle Original Slider with no bun (served as a Keto Slider Bowl in a side cup) reduces calories by 50%—dropping from 140 calories to 70 calories—and cuts net carbohydrates by 92%, dropping from 12 grams of net carbs down to just 1 gram of net carbs from the steam-grilled onions.
