Ingredients
- 1 lb ground beef (80/20 blend for juiciness)
- 2 large onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon sugar
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon Worcestershire sauce
- 4 slices Gruyère cheese
- 4 brioche burger buns
- Fresh thyme for garnish (optional)
Instructions
- Caramelize Onions: In a large skillet, heat butter and olive oil over medium heat. Add sliced onions, sugar, and salt. Cook, stirring occasionally, for about 20-25 minutes until golden brown and caramelized.
