Description
A classic French Onion Soup recipe featuring deeply caramelized onions and a rich beef broth, topped with crusty bread and melted Gruyère cheese.
Ingredients
Scale
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 4 large yellow onions, thinly sliced
- 1 teaspoon granulated sugar
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon black pepper, plus more to taste
- 2 cloves garlic, minced
- 6 cups beef broth
- 1 cup dry white wine
- 1 tablespoon fresh thyme leaves
- 1 bay leaf
- 4 slices crusty bread, about 1 inch thick
- 8 ounces Gruyère cheese, grated
Instructions
- Melt butter and olive oil in a large pot or Dutch oven over medium heat. Add sliced onions, sugar, salt, and pepper. Cook, stirring occasionally, until onions are softened and translucent, about 10-15 minutes.
- Reduce heat to low, cover, and cook for 30-40 minutes, stirring every 10 minutes, until onions are deeply golden brown and caramelized.
- Add minced garlic and cook for 1 minute more until fragrant.
- Pour in the beef broth and white wine. Add thyme leaves and bay leaf. Bring to a simmer, then reduce heat to low and cook for at least 30 minutes to allow flavors to meld. Remove bay leaf.
- Preheat broiler.
- Ladle soup into oven-safe bowls. Place one slice of bread on top of each bowl of soup. Generously sprinkle Gruyère cheese over the bread.
- Place bowls on a baking sheet and broil for 2-3 minutes, or until cheese is melted and bubbly and bread is toasted.
Notes
- For a richer flavor, you can use a combination of yellow and sweet onions.
- If you don’t have white wine, you can substitute with more beef broth or a splash of sherry vinegar.
- Ensure your bowls are oven-safe before broiling.
