Ingredients
1 pound ground beef
1 small onion, finely diced
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/4 teaspoon paprika
1 tablespoon Worcestershire sauce
2 tablespoons butter, plus more for grilling
8 slices sandwich bread (white, sourdough, or brioche)
8 slices cheese (American, provolone, Swiss, or mozzarella)
Instructions
Heat a skillet over medium heat and add the ground beef and diced onion. Cook, breaking up the meat, until the beef is browned and the onions are soft. Drain excess fat if needed.
Season with salt, black pepper, garlic powder, onion powder, paprika, and Worcestershire sauce. Stir well and remove from heat.
Butter one side of each slice of bread.
Place four slices of bread butter-side down in a clean skillet over medium-low heat.
Layer each slice with cheese, a generous amount of the beef mixture, then another slice of cheese. Top with remaining bread slices, butter-side up.
Cook slowly until the bottom is golden and crisp, then carefully flip and cook the other side until the cheese is fully melted and the bread is deeply golden.
Remove from skillet, rest for 1–2 minutes, then slice and serve.
Variations
Add sautéed mushrooms or bell peppers to the beef mixture
Use pepper jack or cheddar for extra flavor
Add a thin layer of mustard or mayo inside the sandwich
Make it spicy with jalapeños or chili flakes
