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.

It’s a fantastic way to elevate a simple burger, and the family couldn’t get enough of the savory goodness in each bite.

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.
