Description
A delicious blend of a burger and a grilled cheese, featuring juicy beef, gooey cheese, and sweet caramelized onions between toasted bread.
Ingredients
- 1 lb ground beef (80/20)
- 4 slices rye or wheat bread
- 4 slices American or Swiss cheese
- 1 large onion, thinly sliced
- 2 tablespoons butter, divided
- Salt and freshly ground black pepper, to taste
- For the secret sauce: equal parts mayonnaise and ketchup, and pickle relish to taste
Instructions
- Heat a large skillet over medium heat and melt 1 tablespoon butter. Add the sliced onion and a pinch of salt. Cook, stirring occasionally, until the onions are deeply golden and sweet, about 8–12 minutes. Remove onions to a bowl and set aside.
- Divide the ground beef into four even portions and gently shape each into a thin patty slightly larger than your bread slices. Season both sides with salt and pepper.
- In the same skillet over medium-high heat, add the patties. Cook about 4 minutes per side for medium doneness. Remove patties and keep warm.
- Assemble the sandwiches: layer a slice of cheese, one patty, more cheese if you like, and a generous spoonful of caramelized onions between two slices of bread.
- Butter the outside faces of each sandwich with the remaining tablespoon of butter.
- Return the skillet to medium heat. Grill sandwiches 3–4 minutes per side, pressing gently with a spatula, until bread is golden and the cheese is melted.
- Make the secret sauce by stirring equal parts mayonnaise and ketchup, then add pickle relish to taste. Serve on the side for dipping or spreading.
Notes
For a gluten-free option, use gluten-free bread. Keep onions warm while cooking patties to maintain temperature.
