- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder

Directions:
- In a large skillet, heat the butter and olive oil over medium heat.

Tips to Make French Onion Soup Burgers
- Be patient while caramelizing the onions. Take your time to get that deep golden color for the best flavor.

Variation
For a twist, try adding blue cheese instead of Gruyère or Swiss. You can also make this into a veggie burger by using a black bean or lentil patty instead of beef.
