How to Make Homemade French Onion Soup
-
Slice the Onions: Begin by slicing 4 large red onions thinly. This step is crucial for achieving that sweet caramelization we crave.
-
Cook the Onions: Melt 4 tablespoons of unsalted butter in a large pot over medium heat. Add the sliced onions and cook, stirring occasionally, until they become golden brown and caramelized—about 20-25 minutes.
-
Add Herbs and Wine: Sprinkle in 1 teaspoon of fresh thyme, then pour in ⅓ cup of port wine or sherry. Continue to cook until the liquid reduces, enhancing that deep, rich flavor.
-
Incorporate Beef Broth: Stir in 6 cups of beef broth, ideally homemade, and bring the mixture to a gentle simmer. Let it simmer for about 30 minutes, allowing all the flavors to meld beautifully.
-
Season the Soup: Taste and season with salt and pepper as desired. This step ensures the soup is seasoned perfectly to your liking.
-
Prepare the Baguette: While the soup is simmering, toast 1 baguette until crispy. Once the soup is ready, place the toasted slices on top of bowls filled with soup.
-
Melt the Cheese: Generously top each bowl with 1 pound of shredded gruyere cheese (or a mix with emmentaler). Broil in the oven until the cheese is bubbling and golden—about 2-3 minutes.
Optional: Garnish with extra fresh thyme for a beautiful touch.

Expert Tips for Homemade French Onion Soup
-
Caramelization Time: The key to rich flavor is patience. Allow the onions to caramelize slowly; rushing this step can lead to bitterness.
-
Quality Matters: Use a high-quality port wine or sherry. The right alcohol enhances the soup’s sweetness and complexity in this Homemade French Onion Soup.
-
Broth Boost: If you can, make your own beef broth. Store-bought options can be salty or lack depth—homemade gives the best results!
-
Toast Smart: Make sure your baguette is adequately toasted for the topping. A soft baguette won’t hold up under the melted cheese and soup.
-
Season at the End: Taste the soup before adding salt and pepper to ensure the seasoning is just right—letting flavors develop affects the final taste.
