White Castle Hamburger Recipe

Ground beef: The base of the sliders, providing the juicy, meaty flavor.

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

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

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

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

Diced onions: Cooked until translucent, they add a sweet and savory base for the beef.

Pickles: Adds a tangy crunch to each slider, balancing the richness of the beef and cheese.

When spreading the ground beef mixture on the baking sheet, use a rolling pin or the back of a spoon to ensure an even thickness. This will help the beef cook uniformly and make it easier to cut into squares after freezing.

• ground beef - Substitute with ground turkey: Ground turkey is a leaner option and provides a similar texture and flavor profile.

• onion soup mix - Substitute with beef bouillon and dried onions: Combining beef bouillon with dried onions can mimic the savory and aromatic qualities of onion 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 offers a rich, creamy texture similar to American cheese.

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

• diced onions - Substitute with shallots: Shallots provide a milder and slightly sweeter flavor compared to regular onions.

• pickles - Substitute with cucumber slices: Fresh cucumber slices offer a crisp texture and a refreshing taste, similar to pickles.

• Allow the hamburgers to cool completely before storing. This prevents condensation, which can make the buns soggy.
• Wrap each hamburger individually in plastic wrap or aluminum foil. This ensures they stay fresh and prevents them from sticking together.
• Place the wrapped hamburgers in an airtight container or a resealable freezer bag. If using a freezer bag, squeeze out as much air as possible before sealing.
• Label the container or bag with the date. This helps you keep track of how long the hamburgers have been stored.
• Store the hamburgers in the refrigerator for up to 3 days. For longer storage, place them in the freezer where they can last up to 3 months.
• To reheat refrigerated hamburgers, preheat your oven to 350°F (175°C). Place the hamburgers on a baking sheet and cover them with aluminum foil. Heat for about 10-15 minutes or until warmed through.
• For frozen hamburgers, thaw them in the refrigerator overnight before reheating. Alternatively, you can reheat them directly from frozen by increasing the oven time to 20-25 minutes.
• If you prefer using a microwave, wrap the hamburger in a damp paper towel and heat on medium power for 1-2 minutes, checking halfway through to ensure even heating.
• Avoid reheating hamburgers multiple times as this can dry them out and affect the texture and flavor.
• For the best experience, always add fresh pickles and diced onions after reheating to maintain their crispness and flavor.

• Preheat your oven to 350°F. Place the hamburgers on a baking sheet and cover them with aluminum foil to retain moisture. Heat for about 10-15 minutes or until warmed through.
• For a quick reheat, use the microwave. Place the hamburgers on a microwave-safe plate and cover them with a damp paper towel. Microwave on medium power for 1-2 minutes, checking halfway through to ensure they are evenly heated.
• If you prefer a crispy texture, use a skillet. Heat a non-stick skillet over medium heat and add a small amount of olive oil. Place the hamburgers in the skillet and cover with a lid. Cook for 2-3 minutes on each side until heated through.
• For an air fryer method, preheat the air fryer to 350°F. Place the hamburgers in the basket in a single layer. Heat for 3-5 minutes, checking halfway to ensure they are not overcooked.
• To reheat using a toaster oven, preheat to 350°F. Place the hamburgers on a baking tray and cover with aluminum foil. Heat for 10-12 minutes, or until they are thoroughly warmed.

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

• Baking sheet: Spread the beef mixture evenly on this surface before freezing.

• Freezer: Freeze the beef mixture for 30 minutes to make it easier to cut into squares.

• Sharp knife: Use this to cut the frozen beef into small squares.

• Skillet: Cook the diced onions until translucent and then cook the beef squares on top of the onions.

• Spatula: Flip the beef squares and handle them while cooking.

• Cheese slicer: Optional, but can be used to slice the cheese if not pre-sliced.

• Serving plate: Place the cooked sliders on this before serving.

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

• Cutting board: Dice the onions on this surface.

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.

Freeze the beef mixture: Spread the beef mixture on a baking sheet and freeze it for easier cutting.

Cook in batches: Cook the beef squares and onions in batches to speed up the process.

Melt cheese quickly: Use a lid to cover the skillet for faster cheese melting.

Assemble efficiently: Lay out all slider buns and pickles in advance for quick assembly.
