Ingredients
Scale
- 4 large yellow onions, thinly sliced
- 3 tbsp unsalted butter
- 1 tbsp olive oil
- 1 tsp sugar
- 2 cloves garlic, minced
- 1/2 cup dry white wine (optional)
- 6 cups beef or vegetable broth
- 2 tsp fresh thyme (or 1 tsp dried thyme)
- Salt and pepper to taste
- 4–6 slices of baguette, toasted
- 1 cup grated Gruyère or Swiss cheese
Instructions
- Caramelize the Onions:
- Heat butter and olive oil in a large pot over medium heat.
- Add onions and sugar, stirring to coat. Cook for 25-30 minutes, stirring frequently, until onions are golden brown and caramelized.
- Add Garlic and Wine:
- Stir in garlic and cook for 1-2 minutes.
- Add white wine (if using) and scrape the bottom of the pot to deglaze. Simmer until the wine reduces by half.
- Simmer the Soup:
- Add broth, thyme, salt, and pepper. Bring to a boil, then reduce heat and simmer for 20-25 minutes.
- Prepare the Topping:
- Preheat your broiler. Ladle the soup into oven-safe bowls.
- Place a slice of toasted baguette on top of each bowl and sprinkle generously with cheese.
- Broil and Serve:
- Place the bowls on a baking sheet and broil until the cheese is melted and bubbly, about 2-3 minutes.
- Serve immediately with extra bread on the side.
Notes
- For deeper flavor, use a combination of beef and chicken broth.
- To make this vegetarian, use vegetable broth and skip the cheese or substitute with a plant-based option.
- Store leftovers without the bread and cheese in the fridge for up to 3 days.
