Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• Yellow onions, thinly sliced
• Butter
• Olive oil
• Garlic, minced
• Beef broth
• Dry white wine (optional)
• Worcestershire sauce
• Bay leaves
• Thyme
• Salt and pepper
• Baguette or crusty bread, sliced
• Gruyère or Swiss cheese, shredded

Directions

1. Caramelize the Onions: In a large pot, melt butter with olive oil over medium heat. Add sliced onions and cook slowly, stirring occasionally, until deeply caramelized (about 40 minutes).
2. Add Aromatics: Stir in minced garlic and cook for another minute until fragrant.
3. Deglaze the Pot: Pour in dry white wine (if using) to deglaze the pan, scraping up any browned bits. Let it simmer until reduced.
4. Simmer the Soup: Add beef broth, Worcestershire sauce, bay leaves, and thyme. Season with salt and pepper. Bring to a simmer and let it cook for about 20-30 minutes to develop flavor. Remove bay leaves and thyme sprigs before serving.
5. Prepare the Bread and Cheese: Preheat the oven broiler. Arrange sliced baguette pieces on a baking sheet and toast them until golden brown.
6. Assemble and Broil: Ladle the soup into oven-safe bowls, top each with toasted bread, and generously sprinkle shredded cheese over the top. Broil for 2-3 minutes, or until the cheese is melted and bubbly.
7. Serve: Carefully remove from the oven and let cool slightly before enjoying.
