Ingredients
Scale
- 6 large yellow onions, thinly sliced
- 3 tablespoons unsalted butter
- 1 tablespoon olive oil
- 3 garlic cloves, minced
- 8 cups beef or vegetable broth
- ½ cup dry white wine
- 2 bay leaves
- 3 sprigs fresh thyme
- Salt and black pepper, to taste
- 1 baguette, sliced and toasted
- 1½ cups grated Gruyère cheese
Instructions
- Slice the onions evenly for uniform cooking.
- Melt butter and olive oil in a large pot over medium heat, add onions with a pinch of salt, and cook slowly until golden brown (about 40 minutes).
- Add garlic, thyme, and bay leaves; cook for 2–3 minutes.
- Deglaze the pan with white wine, scraping up browned bits; let it reduce for a few minutes.
- Add broth, bring to a simmer, cover partially, and cook for 20 minutes. Season gradually with salt and pepper.
- Preheat oven broiler and toast baguette slices.
- Ladle soup into oven-safe bowls, top with toasted bread and Gruyère cheese. Broil 2–4 minutes until bubbly and golden. Serve immediately.
Notes
- Grate cheese fresh for best melt.
- Day-old bread holds up better under the cheese.
- Taste and adjust seasoning slowly; broth and cheese are already salty.
