White Castle Hamburger Recipe

Ground beef: The base of your sliders, providing the essential meaty flavor and texture.

Onion soup mix: Adds a rich, savory flavor to the beef, mimicking the taste of White Castle's original recipe.

Water: Helps to mix the onion soup mix evenly into the ground beef.

American cheese: Melts perfectly over the beef patties, adding a creamy, cheesy layer.

Slider buns: The perfect size for these mini burgers, holding all the flavors together.

Diced onions: Adds a fresh, crunchy texture and a burst of flavor to each bite.

Salt: Enhances the overall flavor of the beef patties.

Pepper: Adds a subtle kick to the sliders, balancing the savory flavors.

To achieve the iconic texture of White Castle hamburgers, it's crucial to spread the ground beef mixture evenly and thinly on the baking sheet. This ensures that the patties cook uniformly and remain juicy. Additionally, scoring the beef into squares before baking helps in maintaining the shape and makes it easier to separate the patties after cooking. When placing the diced onions on the slider buns, ensure they are finely chopped to mimic the classic White Castle experience. Finally, allowing the cheese slices to melt naturally on the hot patties after removing them from the oven adds a creamy texture that complements the savory beef.

• 80/20 blend ground beef - Substitute with ground turkey: Ground turkey is a leaner option and can provide a similar texture and flavor when seasoned well.

• onion soup mix - Substitute with beef bouillon and dried onions: Combining beef bouillon with dried onions can mimic the savory and oniony flavor of the soup mix.

• water - Substitute with beef broth: Beef broth adds more depth of flavor compared to plain water.

• american cheese - Substitute with cheddar cheese: Cheddar cheese melts well and provides a rich, creamy texture similar to American cheese.

• slider buns - Substitute with Hawaiian rolls: Hawaiian rolls are slightly sweet and soft, making them a delicious alternative for slider buns.

• diced onions - Substitute with shallots: Shallots have a milder and slightly sweeter flavor, which can add a different but pleasant taste to the sliders.

• salt - Substitute with soy sauce: Soy sauce can add a savory umami flavor while also providing the necessary saltiness.

• pepper - Substitute with white pepper: White pepper has a slightly different flavor profile but can still provide the necessary heat and spice.

• Allow the hamburger patties to cool completely before storing. This helps to prevent condensation, which can make the buns soggy.
• Wrap each slider individually in plastic wrap or aluminum foil. This ensures that they stay fresh and prevents them from sticking together.
• Place the wrapped sliders in an airtight container or a freezer bag. If using a freezer bag, make sure to squeeze out as much air as possible to prevent freezer burn.
• Label the container or freezer bag with the date. This helps you keep track of how long they have been stored.
• Store the sliders in the refrigerator for up to 3 days if you plan to eat them soon. For longer storage, place them in the freezer where they can last up to 3 months.
• When ready to reheat, remove the sliders from the freezer and let them thaw in the refrigerator overnight.
• To reheat, preheat your oven to 350°F. Place the sliders on a baking sheet and cover them with aluminum foil to prevent drying out. Heat for about 10-15 minutes or until warmed through.
• Alternatively, you can reheat the sliders in the microwave. Place them on a microwave-safe plate and cover with a damp paper towel. Heat on medium power for 1-2 minutes, checking to ensure they are heated evenly.
• For a crispier bun, you can also reheat the sliders in a skillet over medium heat. Cover the skillet with a lid to help the cheese melt and the meat heat through.

• Preheat your oven to 350°F. Place the hamburgers on a baking sheet and cover them with aluminum foil to prevent drying out. Heat for about 10-15 minutes or until warmed through.
• For a quicker method, use a microwave. Place the hamburgers on a microwave-safe plate, cover with a damp paper towel, and heat on medium power for 1-2 minutes. Check and add more time if necessary.
• If you prefer a stovetop method, heat a non-stick skillet over medium heat. Add a small amount of water or beef broth to the pan to create steam, then cover and heat the hamburgers for about 3-5 minutes, flipping halfway through.
• Toaster ovens are also a great option. Preheat to 350°F, place the hamburgers on a tray, and heat for 10-12 minutes, checking periodically to ensure they don't overcook.
• For a crispy bun, separate the buns from the patties and toast them lightly in a toaster or on a skillet before reassembling the hamburgers.

• Mixing bowl: Use this to combine the ground beef, onion soup mix, and water thoroughly.

• Baking sheet: Spread the beef mixture evenly on this to form the patties.

• Knife: Score the beef mixture into 8 equal squares before baking.

• Oven: Preheat and cook the beef mixture at 375°F.

• Spatula: Use this to remove the beef patties from the baking sheet after cooking.

• Cheese slicer: If you need to slice the American cheese, this tool will help.

• Cutting board: Dice the onions on this surface.

• Measuring cup: Measure out the water and diced onions accurately.

• Spoon: Use this to spread the diced onions on the bottom half of the slider buns.

• Serving platter: Arrange the finished sliders on this for serving.

Prepare the beef mixture in advance: Mix the ground beef with onion soup mix and water the night before and refrigerate.

Use pre-diced onions: Save time by buying pre-diced onions from the store.

Preheat the oven: Start preheating your oven while you prepare the beef mixture.

Use parchment paper: Line your baking sheet with parchment paper for easy cleanup.

Melt cheese quickly: Place cheese slices on the hot beef patties immediately after removing from the oven to melt faster.
