What Is French Onion Soup?
Traditional Origins
French onion soup has been a part of French culinary heritage for centuries. Traditionally served as a starter, it features a flavorful broth made from beef stock and slow-cooked onions. The hallmark of this soup is its rich caramelized base and a topping of toasted bread smothered with melted Gruyère or Swiss cheese.
Modern Appeal
Today, French onion soup is loved around the world. It has become a symbol of cozy evenings and rustic elegance, perfect for both weeknight dinners and dinner parties. The layers of flavor, texture, and simplicity in ingredients make it a go-to recipe for many home chefs.
Key Ingredients
Despite its gourmet reputation, French onion soup uses only a few basic components:
- Onions: Yellow or sweet onions are best for deep flavor.
- Butter: Used to sauté and caramelize the onions.
- Garlic: Adds a subtle aromatic depth.
- Beef broth or stock: The base of the soup, giving it richness.
- Dry white wine or sherry: For acidity and complexity.
- Bay leaf and thyme: Classic herbs that complement the sweetness of onions.
- Baguette slices: Toasted to hold up under the soup and cheese.
- Gruyère or Swiss cheese: Perfect for melting and broiling.
How to Make Easy French Onion Soup
Step 1: Caramelize the Onions
Begin by slicing 45 large yellow onions thinly. In a large pot or Dutch oven, melt 23 tablespoons of butter over medium-low heat. Add the onions and a pinch of salt. Stir occasionally, letting the onions cook slowly for 3545 minutes until they’re golden brown and deeply caramelized. This is the most important step, so don’t rush it.
Step 2: Deglaze and Add Flavor
Once the onions are beautifully caramelized, add 2 cloves of minced garlic and cook for another minute. Pour in 1/2 cup of dry white wine (or cooking sherry) to deglaze the pot, scraping up any browned bits from the bottom. Let the wine simmer until slightly reduced, about 23 minutes.
Step 3: Add Broth and Simmer
Add 4 cups of beef broth, 1 bay leaf, and a few sprigs of fresh thyme (or 1/2 teaspoon dried thyme). Bring the soup to a simmer, then reduce the heat and let it cook for 1520 minutes. Taste and adjust seasoning with salt and freshly ground black pepper.
Step 4: Prepare the Bread
While the soup simmers, slice a baguette into thick rounds and toast them under a broiler or in a toaster until golden and crisp. This step prevents the bread from getting soggy too quickly when placed in the soup.
Step 5: Assemble and Broil
Ladle the hot soup into oven-safe bowls. Place one or two toasted baguette slices on top of each serving. Generously sprinkle grated Gruyère or Swiss cheese over the bread. Place the bowls under a broiler for 24 minutes until the cheese is melted, bubbly, and golden brown.
Variations and Substitutions
- Vegetarian option: Use vegetable stock instead of beef broth and add a splash of soy sauce for umami.
- No wine: Skip the wine and use a bit of extra broth or a splash of vinegar for acidity.
- Different cheeses: Try provolone, mozzarella, or even a mix of cheddar and Parmesan if Gruyère isn’t available.
- Make it gluten-free: Use gluten-free bread and check that your broth is gluten-free.
Tips for Success
- Patience is key: Don’t rush the onion caramelization it’s the soul of the soup.
- Broil with care: Keep a close eye when the soup is under the broiler to avoid burning the cheese.
- Use quality broth: A rich, flavorful broth is essential. Homemade or low-sodium versions are ideal.
- Serve hot: French onion soup is best enjoyed piping hot with cheese still gooey and the bread slightly crisp.
