Ingredients
-
5 large yellow onions, thinly sliced
-
4 tablespoons unsalted butter
-
1 teaspoon sugar
-
1 teaspoon salt
-
2 tablespoons all-purpose flour
-
½ cup dry white wine
-
8 cups beef stock
-
1 bay leaf
-
1 teaspoon dried thyme
-
1 baguette, sliced and toasted
-
2 cups grated Gruyère cheese
Step-by-Step Directions
-
Caramelize the onions: In a large Dutch oven, melt butter over medium heat. Add onions, sugar, and salt. Cook slowly, stirring often, until the onions are deeply caramelized — about 45 minutes.
-
Build the flavor: Stir in flour and cook for 1–2 minutes. Deglaze the pot with white wine, scraping up all those flavorful browned bits. Add beef stock, bay leaf, and thyme. Simmer uncovered for 30 minutes.
-
Finish and serve: Discard the bay leaf, then ladle soup into oven-safe bowls. Top each with a toasted baguette slice and a generous sprinkle of Gruyère cheese. Broil until the cheese is bubbly and golden. Serve hot.
Tips for the Best French Onion Soup
-
Be patient with the onions. Slow caramelization is the secret to deep, rich flavor.
-
Use good-quality cheese. Gruyère is classic, but a mix of Gruyère and Parmesan adds even more depth.
-
Make it ahead. The onion and broth base tastes even better the next day — just add bread and cheese before serving.
