Description

Savory French Onion Burgers featuring caramelized onions and melted cheese, perfect for a gourmet twist on a classic favorite.


Ingredients

Units Scale
  • 1 lb ground beef
  • 2 large yellow onions, thinly sliced
  • 2 tbsp unsalted butter
  • 1 tbsp olive oil
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder
  • 4 slices Swiss or Gruyère cheese
  • 4 hamburger buns
  • 1 tbsp Worcestershire sauce
  • Optional: mayonnaise, mustard, or aioli for serving

Instructions

  1. In a large skillet, heat butter and olive oil over medium heat. Add sliced onions and cook slowly, stirring often, until caramelized (about 25–30 minutes). Add Worcestershire sauce and stir to combine.
  2. While onions cook, preheat grill or skillet to medium-high heat.
  3. In a bowl, mix ground beef with salt, pepper, and garlic powder. Form into 4 patties.
  4. Cook patties for 4–5 minutes per side, or until desired doneness. In the last minute of cooking, place a slice of cheese on each patty and cover to melt.
  5. Toast the buns if desired.
  6. Assemble burgers by placing a patty on each bun bottom, topping with a generous portion of caramelized onions, and finishing with the top bun. Add condiments if desired.

Notes

  • Use Gruyère for a more authentic French onion flavor.
  • Caramelized onions can be made ahead and stored in the fridge.
  • For extra flavor, spread garlic aioli on the buns.
