Introduction

This French Onion Soup Burger recipe brings the beloved flavors of French onion soup into a delicious burger form that’s sure to impress. When I made these burgers for a family gathering, they were a hit! The caramelized onions brought out a deep, rich flavor, and the Gruyère cheese melted beautifully over the patties.

Ingredients

• For the Burgers:
• 1 lb ground beef
• Salt and pepper, to taste
• 2 tablespoons Worcestershire sauce
• 4 slices of Gruyère or Swiss cheese
• 4 hamburger buns
• For the Caramelized Onions:
• 2 large onions, thinly sliced
• 2 tablespoons butter
• 1 teaspoon sugar
• 1/2 cup beef broth
• 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
• For Garlic Butter Buns (optional):
• Additional butter
• 1 clove garlic, minced

Instructions

1. Caramelize the Onions: In a large skillet over medium heat, melt the butter. Add the sliced onions and sugar, cooking for about 20-25 minutes or until the onions are deeply caramelized. Stir occasionally, and add a splash of beef broth if they start to stick. Once caramelized, stir in fresh thyme.
2. Prepare the Burger Patties: In a mixing bowl, season the ground beef with salt, pepper, and Worcestershire sauce. Form the mixture into 4 equal patties.
3. Cook the Patties: In a separate skillet or on a grill, cook the patties to your desired level of doneness.
4. Prepare Garlic Butter Buns: If desired, mix butter and minced garlic and spread on each bun half. Toast until golden brown.
5. Assemble the Burgers: On the bottom half of each bun, place a burger patty. Top with a generous amount of caramelized onions and a slice of cheese. Place under a broiler for a few minutes until the cheese melts and bubbles.
6. Serve: Sprinkle fresh thyme over the melted cheese, cover with bun tops, and serve immediately.
