White Castle Hamburger Recipe

Ground beef: The main protein for the sliders, providing a juicy and flavorful base.

Onion soup mix: Adds a savory depth of 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 squares, adding a creamy and tangy element.

Slider buns: Small buns that hold the beef squares, cheese, onions, and pickles together.

Diced onions: Provides a crunchy texture and a burst of flavor, essential for the authentic taste.

Pickles: Adds a tangy and slightly sweet contrast to the savory beef and cheese.

To achieve the classic White Castle flavor, make sure to finely dice the onions and scatter them on the skillet before placing the beef squares on top. The steam from the onions will infuse the beef with a rich, savory taste, mimicking the original cooking method used by White Castle.

• 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 dried minced onions and beef bouillon: This combination can mimic the flavor profile of onion soup mix without the added preservatives.

• 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 similar creamy texture with a slightly sharper flavor.

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

• diced onions - Substitute with shallots: Shallots have a milder and sweeter flavor compared to regular onions, which can add a subtle complexity to the sliders.

• pickles - Substitute with cucumber slices: Fresh cucumber slices can provide a similar crunch and freshness without the tanginess of pickles.

• Allow the ground beef mixture to cool completely before storing. This prevents condensation and keeps the hamburgers from becoming soggy.
• For short-term storage, place the cooked beef squares in an airtight container. Layer them with parchment paper to prevent sticking.
• Store the diced onions separately in a small airtight container to maintain their crunch and freshness.
• If you plan to enjoy the White Castle hamburgers within 2-3 days, keep them in the refrigerator. Ensure the temperature is set to 40°F (4°C) or below.
• For longer storage, wrap each beef square individually in plastic wrap or aluminum foil. This helps to preserve their flavor and texture.
• Place the wrapped beef squares in a freezer-safe bag or container. Label with the date to keep track of freshness.
• Freeze the beef squares for up to 3 months. When ready to use, thaw them in the refrigerator overnight.
• To reheat, preheat your oven to 350°F (175°C). Place the beef squares on a baking sheet and cover with aluminum foil. Heat for about 10-15 minutes or until warmed through.
• Alternatively, you can reheat the beef squares in a skillet over medium heat. Add a splash of water and cover with a lid to steam and retain moisture.
• Assemble the hamburgers with fresh slider buns, diced onions, pickles, and a slice of american cheese for that classic White Castle experience.

• Preheat your oven to 350°F. Place the leftover hamburgers on a baking sheet and cover them with aluminum foil to prevent them from 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 and cover them with a damp paper towel. Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating.
• If you prefer a crispy texture, reheat the hamburgers in a skillet. Heat a non-stick skillet over medium heat, add a small amount of olive oil or butter, and cook the hamburgers for 2-3 minutes on each side until heated through.
• For an air fryer method, preheat your air fryer to 350°F. Place the hamburgers in the basket in a single layer and heat for 3-4 minutes, checking halfway to ensure they are evenly reheated.
• To retain the juiciness, use a steamer. Place the hamburgers in a steamer basket over boiling water, cover, and steam for about 5 minutes or until heated through.

• 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 until it becomes firm enough to cut into squares.

• Sharp knife: Cut the frozen beef into small squares with precision.

• Hot skillet: Cook the beef squares on this to achieve a nice browning.

• Spatula: Flip the beef squares on the skillet to ensure even cooking.

• Cheese slicer: If your American cheese isn't pre-sliced, use this to get even slices.

• Cutting board: Place the frozen beef on this surface for cutting.

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

• Serving plate: Arrange the cooked beef squares with cheese, diced onions, and pickles on slider buns before serving.

Prepare in advance: Mix the ground beef with onion soup mix and water the night before and freeze it overnight.

Use a food processor: Quickly dice the onions using a food processor to save chopping time.

Pre-cut cheese: Have the American cheese slices ready and separated to easily place on the beef squares.

Pre-slice buns: Slice the slider buns ahead of time to streamline assembly.

Batch cooking: Cook multiple beef squares at once on a large skillet to save time.
