Description
This comforting homemade French Onion Soup features deeply caramelized yellow onions simmered in a rich, savory beef broth. By skipping the traditional wine and focusing on the slow-cooked sweetness of the onions, this recipe achieves a complex and deeply satisfying flavor profile. Topped with toasted French baguette slices and a bubbling, molten layer of Gruyère cheese, it is the ultimate gourmet comfort food perfect for any chilly evening.
Ingredients
6 large yellow onions, thinly sliced
4 tablespoons unsalted butter
2 tablespoons olive oil
1 tablespoon all-purpose flour
6 cups high-quality beef stock
2 cloves garlic, minced
1 teaspoon dried thyme
1/2 teaspoon salt
1/4 teaspoon black pepper
1 loaf French baguette, sliced into 1-inch rounds
2 cups Gruyère or Swiss cheese, shredded
Instructions
Heat butter and oil in a large heavy-bottomed pot over medium heat.
Add sliced onions and cook, stirring every few minutes, for 35-40 minutes until deeply golden brown.
Sprinkle flour over onions and stir for 2 minutes to cook off the raw flour taste.
Add garlic and thyme, stirring until fragrant.
Pour in beef stock, bring to a boil, then reduce heat to low and simmer uncovered for 20 minutes.
While soup simmers, toast baguette slices in the oven until crisp.
Ladle soup into oven-safe bowls, top with a toasted bread slice, and cover generously with shredded cheese.
Broil for 2-3 minutes on a baking sheet until the cheese is bubbling and golden brown.
Notes
Store the soup base in an airtight container in the refrigerator for up to 4 days. The flavors often deepen overnight. Ensure you use oven-safe bowls to withstand the broiler heat.
