French Onion Soup Burgers

ingredients:

• 1 lab ground beef
• 2 large onions, thinly sliced
• 2 tablespoons butter
• 1 teaspoon sugar
• 1/2 cup beef broth
• 2 tablespoons Worcestershire sauce
• 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
• Salt and pepper, to taste
• 4 slices of Gruyère or Swiss cheese
• 4 hamburger buns
• 1 clove garlic, minced (optional for garlic butter buns)
• Additional butter for buns

Instructions:

1. Caramelize the Onions:
   • In a large skillet over medium heat, melt the butter.
   • Add the sliced onions and sugar, cooking until the onions are deeply caramelized and sweet, about 20-25 minutes. Stir occasionally.
   • If the onions start to stick, add a splash of beef broth to deglaze the pan.
2. Prepare the Burger Patties:
   • In a bowl, season the ground beef with salt, pepper, and Worcestershire sauce.
   • Form the mixture into 4 equal-sized patties.
   • Cook the patties in a separate skillet or on a grill to your desired level of doneness.
3. Assemble the Burgers:
   • If you want garlic butter buns, mix butter with minced garlic and spread it on the buns, then toast until golden.
   • Place a cooked burger patty on the bottom half of each bun.
   • Top each patty with a generous helping of caramelized onions and a slice of cheese.
   • Broil the assembled burgers for a few minutes until the cheese is melted and bubbly.
   • Sprinkle fresh thyme over the cheese, cover with the bun tops, and serve immediately.
