White Castle Hamburger Recipe

Ground beef: The main protein for the sliders, providing the classic beefy flavor.

Dinner rolls: Small, soft rolls that serve as the perfect bun for these mini burgers.

Onions: Finely chopped to cook evenly and infuse the beef with their flavor.

To achieve the signature texture of White Castle hamburgers, make sure to press the ground beef into an even, thin layer over the onions.

Additionally, using a spatula to press down on the beef while it cooks helps to create a slight crust, enhancing the overall taste and texture of the hamburger.

• Allow the hamburgers to cool completely before storing. This helps prevent condensation, which can make the bread 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 freezer bag. If using a freezer bag, remove as much air as possible before sealing.
• Label the container or bag with the date. This helps you keep track of how long they’ve been stored.
• Store the hamburgers in the refrigerator if you plan to eat them within 3-4 days. For longer storage, place them in the freezer where they can last up to 2-3 months.
• To reheat, unwrap the hamburgers and place them on a microwave-safe plate. Microwave on medium power for 1-2 minutes or until heated through.
• Alternatively, you can reheat the hamburgers in an oven. Preheat the 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.
• If reheating from frozen, allow the hamburgers to thaw in the refrigerator overnight before following the reheating instructions.

• Preheat your oven to 350°F (175°C). Wrap each hamburger in aluminum foil to keep them moist. Place them on a baking sheet and heat for about 10-15 minutes until warmed through.
• For a quicker method, use a microwave. Place the hamburger on a microwave-safe plate. Cover with a damp paper towel to prevent drying out. Heat on medium power for 1-2 minutes, checking halfway through.
• If you prefer a crispy texture, use a skillet. Preheat the skillet over medium heat. Add a small amount of butter or olive oil. Place the hamburger in the skillet and cover with a lid. Heat for 2-3 minutes on each side until warmed through and slightly crispy.
• For an air fryer, preheat to 350°F (175°C). Place the hamburger in the air fryer basket. Heat for 3-4 minutes, checking halfway to ensure they don't overcook.
• If you have a toaster oven, preheat to 350°F (175°C). Place the hamburger on a baking sheet and cover with aluminum foil. Heat for 10-12 minutes until warmed through.
