Ingredients
1.5 lbs ground beef (80/20)
1 tsp salt
1/2 tsp black pepper
4 slices Swiss cheese
4 hamburger buns
2 tbsp butter, softened
2 large onions, thinly sliced
2 tbsp olive oil
1 tbsp brown sugar
2 tbsp balsamic vinegar
4 tbsp Dijon mustard
4 leaves lettuce
4 slices tomato
Instructions
Preheat grill or skillet over medium-high heat.
Divide beef into 4 equal portions and shape into patties, slightly larger than buns. Season with salt and pepper.
Cook patties for 4-5 minutes per side for medium, or to desired doneness. In the last minute, top each patty with a slice of Swiss cheese and cover to melt.
Meanwhile, heat olive oil in a skillet over medium heat. Add onions and cook, stirring occasionally, until softened and golden, about 8 minutes. Stir in brown sugar and balsamic vinegar; cook 1 more minute.
Split buns and spread cut sides with butter. Toast on grill or in a separate skillet until golden.
Spread Dijon mustard on bottom buns. Top with lettuce, tomato, patty with cheese, caramelized onions, and bun top.
Tips
For best results, use freshly ground beef and avoid overworking the meat.
Let patties rest for 2 minutes after cooking to retain juices.
