1/4 cup butter
3 tablespoons olive oil, divided
4 large yellow onions (about 5 cups), thinly sliced
1 1/2 teaspoons sugar
3 cloves garlic, minced
1 teaspoon salt
1/2 teaspoon black pepper
3/4 cup dry white wine
2 teaspoons balsamic vinegar
6 cups beef broth (or vegetable broth for a vegetarian version)
2 bay leaves
8 slices of French baguette
2 cups shredded Gruyère cheese or 4 slices Swiss cheese
Fresh chopped parsley for topping (optional)
Caramelize Onions: In a large pot, melt butter and 2 tablespoons of olive oil over medium heat. Add thinly sliced onions and sugar, stirring occasionally until onions are caramelized and golden brown, about 30-40 minutes.
Add Aromatics: Stir in minced garlic, salt, and black pepper, cooking for an additional 1-2 minutes until fragrant.
Deglaze Pan: Pour in dry white wine and balsamic vinegar, scraping the bottom of the pot to loosen any browned bits. Cook for 2-3 minutes to allow the alcohol to evaporate.
Simmer Soup: Add beef broth and bay leaves to the pot, bringing the mixture to a simmer. Allow the soup to simmer for 20-30 minutes to allow the flavors to meld together.
Prepare Bread: While the soup simmers, preheat the oven broiler. Brush baguette slices with remaining olive oil and place them on a baking sheet. Toast under the broiler for 1-2 minutes per side, until golden brown.
Assemble Soup: Ladle the hot soup into oven-safe bowls. Top each bowl with a toasted baguette slice and sprinkle generously with shredded Gruyère or Swiss cheese.
Broil Cheese: Place the bowls of soup under the broiler for 2-3 minutes, until the cheese is melted and bubbly.
Serve: Carefully remove the bowls from the oven and garnish with fresh chopped parsley if desired. Serve hot and enjoy the luxurious flavors of French Onion Soup!
Cook Notes and Variations:
Vegetarian Version: Substitute beef broth with vegetable broth for a vegetarian-friendly version of this soup.
Cheese Options: Experiment with different types of cheese such as mozzarella, provolone, or even cheddar for a unique twist on this classic dish.
Add Depth: Enhance the flavor of the soup by adding a splash of Worcestershire sauce or a sprinkle of thyme during the simmering process.
Keto and Low-Carb Versions:
Keto Option: Skip the baguette slices or use low-carb bread alternatives such as almond flour bread or cloud bread. Opt for a dry white wine with low residual sugar content or omit it altogether. Use a keto-friendly sweetener such as erythritol instead of sugar for caramelizing the onions.
Low-Carb Option: Similarly, reduce the amount of onions and substitute them with low-carb vegetables such as cauliflower or bell peppers. Use a homemade beef or vegetable broth with no added sugars or carbohydrates.
Frequently Asked Questions (FAQs):
Can I use store-bought broth instead of making it from scratch? Yes, you can use store-bought beef or vegetable broth as a convenient alternative. Look for low-sodium options to control the salt content of the soup.
