A Juicy Lucy burger stuffs molten cheese inside the beef patty for a gooey, explosive bite that's a Minneapolis family institution. This high protein, carnivore-favorite burger is a must-try for cheese lovers.
Divide the ground beef into 8 equal portions and flatten each into thin patties (about ¼ inch thick).
Place one slice of American cheese in the center of 4 patties, folding cheese to fit. Top each with a second patty and pinch edges tightly to seal, ensuring no gaps.
Season both sides of the patties with kosher salt and black pepper, pressing seasoning gently to adhere.
Heat a skillet or grill to medium-high. Add butter and cook sealed patties for 4-5 minutes per side, maintaining even medium heat for a golden crust and allowing cheese to fully melt inside.
Rest burgers for 2 minutes after cooking, then serve on toasted buns with lettuce, tomato, and red onion. Slice carefully to experience the molten cheese core.
