Ingredients
Scale
- 5 large yellow onions, thinly sliced
- 3 tbsp unsalted butter
- 1 tbsp olive oil
- 3 cloves garlic, minced
- 1 tsp sugar
- 1 tsp salt
- 1/2 tsp black pepper

- 1/2 cup dry white wine (optional)
- 2 sprigs fresh thyme (or 1 tsp dried thyme)
- 1 bay leaf
- 1 baguette, sliced and toasted
