Ingredients for White Castle Sliders
-
1 pound ground beef (80/20 blend for juiciness)
-
1 teaspoon salt
-
½ teaspoon black pepper
-
½ teaspoon garlic powder
-
1 large onion, finely diced
-
½ cup beef broth (for extra flavor)
-
12 slider buns or dinner rolls
-
6 slices American cheese (optional)

12 dill pickle slices

2 tablespoons mustard or ketchup (optional)
Step-by-Step Instructions for White Castle Sliders
Step 1: Prepare the Beef Mixture
In a bowl, combine the ground beef, salt, black pepper, and garlic powder. Mix well but do not overwork the meat, as this can make the patties tough.
Step 2: Shape the Patties
On a sheet of parchment paper or plastic wrap, press the beef into a ¼-inch thick rectangle, roughly the size of a 9×13-inch baking dish. Use a knife or pizza cutter to score the beef into 12 small square patties without cutting all the way through.
Step 3: Prepare the Onions
Finely dice the onion and spread it evenly across a large skillet or griddle. Pour the beef broth over the onions to help them steam and soften.
Step 4: Cook the Patties
Place the sheet of ground beef on top of the onions, aligning the squares with the onions underneath. Cook over medium heat for about 5 minutes, allowing the steam from the onions to cook the patties.
Step 5: Add the Buns
Place the top halves of the slider buns directly over the beef patties while they cook. This allows them to absorb the steam and soften, just like White Castle’s signature style.
Step 6: Cut and Assemble the Sliders
Once the beef is fully cooked, remove it from the heat. Cut along the scored lines to separate the individual sliders. Place each patty on the bottom half of a bun. Add a slice of cheese, a pickle, and mustard or ketchup, if desired.
Step 7: Serve and Enjoy
Serve the sliders warm, and enjoy your homemade White Castle experience!
Ingredient Background
White Castle Sliders may seem simple, but each ingredient plays a crucial role in creating their signature taste and texture. From the juicy beef patties to the perfectly steamed buns, understanding these ingredients will help you achieve an authentic homemade version of this fast-food favorite.
The ground beef used in these sliders is typically an 80/20 blend, meaning it contains 80% lean meat and 20% fat. This ratio ensures the patties remain juicy while cooking. The key to achieving the classic White Castle texture is to press the meat into a thin, uniform sheet before cooking. Unlike traditional burgers, these patties aren’t flipped, but instead, they steam over a bed of onions, absorbing their rich, savory flavors.
Onions are a defining ingredient in White Castle Sliders. They add a deep, slightly sweet flavor and release moisture that steams the beef as it cooks. Finely dicing the onions ensures they distribute evenly across the skillet, creating a consistent flavor throughout the sliders. Many people believe White Castle uses dehydrated onions, which rehydrate during cooking, but fresh onions provide an even better taste.
The slider buns are another essential component. White Castle uses small, soft, pillowy buns that absorb the steam from the onions and beef, giving them their signature texture. Using dinner rolls or soft slider buns replicates this effect at home. To get the full White Castle experience, placing the top buns on the patties while they cook allows them to soak up the flavors and become incredibly soft.
Technique Tips for White Castle Sliders
Perfecting homemade White Castle Sliders requires mastering a few key techniques. The way the beef is shaped, the onions are prepared, and the sliders are cooked all contribute to achieving that iconic fast-food flavor.
One important technique is pressing and scoring the beef before cooking. Instead of forming individual patties, the ground beef should be spread out into a single thin rectangle and lightly scored into squares. This ensures even cooking and makes it easier to separate the sliders after cooking. Keeping the beef uniform in thickness prevents some patties from overcooking while others remain underdone.
Another crucial step is cooking the sliders over onions instead of direct heat. Traditional burgers are grilled or fried directly on a pan, but White Castle’s method involves placing the raw beef over finely diced onions. As the onions cook, they release moisture, which steams the patties. This not only adds incredible flavor but also keeps the meat juicy and tender.
For the most authentic taste, steaming the buns is key. Once the patties are almost cooked through, placing the top halves of the buns directly over the beef allows them to absorb the steam from the onions and meat. This gives them the soft, slightly chewy texture that White Castle sliders are known for. If you prefer a firmer bun, you can skip this step and toast them separately.
Alternative Presentation Ideas
While classic White Castle Sliders are served with soft buns, steamed onions, and a beef patty, there are plenty of creative ways to switch up their presentation while keeping the same delicious flavors.
One unique option is to turn them into a slider casserole. Instead of cooking individual sliders, press the beef into a baking dish, top with onions, and bake. Once cooked, place the top buns on and bake for a few more minutes to steam them. This method is great for serving a crowd, as you can cut the sliders into portions right from the dish.
Another fun variation is lettuce-wrapped sliders. Instead of using buns, wrap each patty in a crisp lettuce leaf for a low-carb, gluten-free version. This adds a refreshing crunch while keeping the sliders lighter and healthier.
For a bite-sized twist, you can make White Castle-style meatballs. Shape the beef into small meatballs, cook them with onions, and serve them on mini buns or skewers for a fun party appetizer. These meatball sliders still capture the essence of White Castle but in a slightly different form.
Freezing and Storing White Castle Sliders
If you want to enjoy White Castle Sliders later, proper storage and reheating techniques ensure they maintain their signature taste and texture.
For refrigerating leftovers, store fully assembled sliders in an airtight container and keep them in the fridge for up to 3 days. To reheat, wrap them in a damp paper towel and microwave them for about 30 seconds, which helps restore their soft, steamed texture.
For freezing sliders, it’s best to store the cooked patties separately from the buns. Place the patties on a baking sheet, freeze until solid, and then transfer them to a freezer bag. The buns can be stored at room temperature or frozen separately. When ready to eat, reheat the patties in a skillet or microwave, then steam the buns by wrapping them in a damp paper towel and microwaving for 20-30 seconds.
If freezing assembled sliders, wrap each one individually in plastic wrap and store them in a freezer bag. To reheat, microwave for 1 minute, flipping halfway through, or bake in a 300°F oven for 10 minutes.
Healthier Twist Ideas
For those looking to make White Castle Sliders a little healthier, there are a few simple modifications that maintain the great taste while cutting down on fat, carbs, or calories.
One way to lighten them up is by using lean ground turkey or chicken instead of beef. These options still provide a juicy patty but with less fat and fewer calories. Adding a bit of Worcestershire sauce or soy sauce can enhance the umami flavor, mimicking the richness of beef.
To cut down on carbs, swap out the buns for lettuce wraps or whole wheat slider buns. Whole wheat buns add fiber and nutrients while keeping the sliders feeling just as satisfying. For an ultra-low-carb option, serve the patties over a bed of sautéed onions and mushrooms instead of a bun.
Reducing sodium is another simple tweak. White Castle Sliders can be quite salty, so using low-sodium beef broth and seasoning the patties with fresh herbs instead of extra salt can make them a healthier choice. Using fresh onions rather than pre-packaged dehydrated ones also helps keep sodium levels in check.
Serving Suggestions for Events
White Castle Sliders are perfect for a variety of events, whether you’re hosting a party, game night, or casual dinner. Their small size makes them ideal for serving as appetizers, snacks, or part of a larger meal.
For game day gatherings, consider setting up a slider bar. Offer a variety of toppings, such as cheese, pickles, jalapeños, and different sauces, so guests can customize their sliders. Serving them alongside fries or onion rings completes the fast-food experience.
For family dinners, pair the sliders with a simple side salad, roasted vegetables, or sweet potato fries for a balanced meal. Kids love these mini burgers, making them a fun and easy dinner option for picky eaters.
If you’re serving White Castle Sliders at a holiday party, elevate them with gourmet toppings. Try adding caramelized onions, truffle aioli, or smoked cheddar for a more upscale twist on this classic comfort food.
