Ingredients
For The Soup
- 6 large yellow onions thinly sliced
- 4 tbsp salted butter
- 1 tbsp olive oil
- 2 tsp minced garlic
- 1 tsp sugar helps caramelize the onions
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp thyme
- 1/4 cup dry white wine optional, but adds great flavor
- 2 tbsp all-purpose flour
- 6 cups beef broth or a mix of beef & chicken broth for balance
- 1 tsp Worcestershire sauce
- 1 bay leaf
- Optional: splash of balsamic vinegar for depth
For The Topping
- 1 French baguette sliced into ½-inch rounds
- 2 cups shredded Gruyère cheese or mix Gruyère + mozzarella
- ½ cup grated Parmesan cheese
Instructions
- Caramelize the Onions - In a large Dutch oven or soup pot, melt butter and olive oil over medium-low heat. Add sliced onions, sugar, salt, and pepper. Cook slowly for 35–45 minutes, stirring occasionally until onions are deep golden brown and caramelized.
- Add Garlic & Flour - Stir in minced garlic and cook for 1 minute. Sprinkle flour over the onions and stir for another 2–3 minutes to thicken the base.
- Deglaze & Simmer - Pour in wine (if using) to deglaze the pot, scraping up any brown bits. Add broth, thyme, Worcestershire, and bay leaf. Bring to a boil, then reduce heat and simmer for 25–30 minutes. Taste and adjust seasoning.
- Toast the Bread - While the soup simmers, toast the baguette slices until golden.
- Assemble & Broil- Ladle soup into oven-safe bowls. Top each with a toasted baguette slice and a generous handful of cheese.
- Broil - Place under the broiler for 2–3 minutes or until the cheese is melted and bubbly.
