Description
A cozy and deeply flavorful French onion soup made with caramelized onions, savory broth, and topped with toasted baguette slices and bubbling Gruyère cheese. A comforting classic perfect for chilly days.
Ingredients
Scale
- 5 large yellow onions, thinly sliced
- 3 tablespoons unsalted butter
- 1 tablespoon olive oil
- 2 garlic cloves, minced
- 1/2 cup dry white wine
- 6 cups beef broth
- 2 bay leaves
- 3 sprigs fresh thyme
- 1 teaspoon salt (adjust to taste)
- 1/2 teaspoon freshly cracked black pepper
- 1 small baguette, sliced and toasted
- 2 cups shredded Gruyère cheese
Instructions
- Set your oven to broil and ensure your soup bowls are oven-safe.
- In a Dutch oven over medium heat, melt butter and olive oil. Add onions and cook for 40–45 minutes, stirring occasionally, until deeply caramelized. Add minced garlic during the last few minutes.
- Deglaze with dry white wine, scraping the bottom of the pot. Stir in beef broth, bay leaves, thyme, salt, and pepper. Simmer for 20 minutes.
- Remove bay leaves and thyme sprigs. Ladle soup into broiler-safe bowls. Top with toasted baguette slices and shredded cheese.
- Place bowls under the broiler for 2–3 minutes until the cheese is bubbly and golden brown.
- Allow to cool slightly, then serve while hot and melty.
Notes
- Use low-sodium broth to control saltiness.
- Day-old bread works best for toasting and holding up in the soup.
- Caramelize onions slowly for the best flavor—no rushing this step.
