How to Make French Onion Soup
-
Caramelize Onions: In a large pot over medium heat, melt the butter and oil together. Add the sliced onions, salt, and pepper, and cook uncovered for 45-55 minutes. Stir frequently until the onions are deeply golden brown and sweet, adjusting the heat as needed to prevent burning.
-
Deglaze and Build Flavor: Pour in the wine and dry sherry, then raise the heat to medium-high. Boil for about 5-6 minutes until most of the liquid evaporates. Sprinkle in the flour, stirring for 1 minute to combine.
-
Simmer Soup: Gradually add the beef broth while stirring everything together. Toss in the bay leaf, thyme, and Worcestershire sauce. Bring the mixture to a boil, then reduce to a simmer and cook for 20 minutes.
-
Prepare Baguette: Preheat your oven to 400°F. Slice the baguette into ½-inch thick pieces and arrange them on a baking sheet. Bake for 8-10 minutes, or until crisp and golden brown.
-
Cheese Topping: After simmering, remove the bay leaf and thyme. In ovenproof bowls, ladle the hot soup, layer with crispy bread, and heap on the grated cheese generously.
-
Broil: Place the bowls under the broiler for a few minutes, keeping an eye on them, until the cheese is melted and bubbly, creating a delicious golden crust.
Optional: Top with fresh herbs for an added burst of flavor.

Expert Tips for French Onion Soup
-
Caramelization Confidence: Cook onions slowly and patiently over moderate heat; this develops their natural sweetness without burning.
-
Avoid Sticking: If onions begin to stick, deglaze the pot with a splash of water or broth. This prevents burning and enhances the flavor.
-
Taste Testing: Always taste the soup at the end of simmering. Adjust seasonings like salt and pepper to achieve the perfect balance for your French Onion Soup.
-
Broiling Vigilance: Keep a close eye while broiling to ensure the cheese melts beautifully without burning or overcooking.
-
Alternative Cheeses: Don’t hesitate to experiment with different cheeses. While Gruyère is classic, other melting cheeses like Fontina or Mozzarella can offer unique flavors.
