Ingredients
Scale
Soup Base
- 0.5 cup unsalted butter
- 2 tablespoons olive oil
- 4 cups sliced onions
- 5 cups beef broth
- 2 tablespoons dry sherry
- 1 teaspoon dried thyme
- 1 pinch salt
- 1 pinch pepper
Toppings
- 4 slices French bread
- 4 slices provolone cheese
- 2 slices Swiss cheese, diced
- 0.25 cup grated Parmesan cheese
Instructions
- Gather Ingredients: Assemble all the ingredients needed for the soup to ensure a smooth cooking process.
- Sauté Onions: Melt butter with olive oil in an 8-quart stock pot over medium heat. Add sliced onions and stir continually until the onions are tender and translucent but not browned.
- Simmer Soup: Add the beef broth, dry sherry, and dried thyme to the pot. Season with salt and pepper to taste. Let the soup simmer gently for 30 minutes to develop rich flavors. Meanwhile, preheat the oven broiler.
- Prepare Bowls: Ladle the hot soup into oven-safe serving bowls. Place one slice of French bread on top of each bowl. If preferred, break the bread into pieces for easier layering.
- Add Cheese Layers: Layer each slice of bread with one slice of provolone cheese, half a slice of diced Swiss cheese, and one tablespoon of grated Parmesan cheese.
- Broil: Place the bowls on a rimmed sheet pan and broil in the preheated oven for 2 to 3 minutes, until the cheese bubbles and browns slightly.
- Serve: Remove from oven carefully and serve hot. Enjoy the comforting combination of savory soup and cheesy toasted bread topping.
Notes
- This French onion soup is enriched by the combination of three cheeses, adding depth and texture.
- Be careful not to brown the onions during sautéing to maintain a sweet and mild flavor.
- Use oven-safe bowls that can withstand broiling to ensure safe cooking.
- If you prefer a vegetarian option, substitute beef broth with vegetable broth and omit the Swiss cheese if containing rennet.
- Bread can be toasted slightly beforehand if you want extra crunch under the cheese layers.
