Prep and Cook Time
- Preparation: 20 minutes
- Cooking: 1 hour 10 minutes
- Total Time: 1 hour 30 minutes
Yield
Serves 6 generous bowls
Difficulty Level
Medium – Requires patience for perfect caramelization but simple techniques overall
Ingredients
- 6 large yellow onions, thinly sliced
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 1 teaspoon sugar (to aid caramelization)
- 3 cloves garlic, minced
- 1/2 cup dry sherry (optional, for deglazing without water)
- 8 cups high-quality beef broth, preferably homemade or low-sodium store-bought
- 2 sprigs fresh thyme
- 1 bay leaf
- Salt and freshly ground black pepper to taste
- Baguette slices, toasted
- 2 cups grated Gruyère cheese
Instructions
- Prepare the onions: Heat butter and olive oil in a large, heavy-bottomed pot over medium heat. Add the sliced onions along with the sugar. Sauté gently, stirring often, allowing the onions to soften and slowly caramelize to a deep golden brown, about 45-50 minutes. Be patient-this step builds the soup’s signature depth and sweetness.
- Add garlic and deglaze: Stir in the minced garlic and cook for 1-2 minutes until fragrant. Pour in the dry sherry (if using) and scrape the bottom to release any fond, intensifying flavor.
- Simmer the broth: Add the beef broth, thyme sprigs, and bay leaf. Bring the soup to a simmer and cook uncovered for 30 minutes, allowing the flavors to meld. Season with salt and fresh black pepper. Remove the herb sprigs and bay leaf before serving.
- Prepare the topping: While the soup simmers, preheat your oven broiler. Arrange toasted baguette slices on a baking sheet and generously top each with grated Gruyère.
- Assemble and broil: Ladle the hot soup into oven-safe bowls. Float the cheesy baguette slices on top. Place under the broiler until the cheese bubbles and turns a luscious golden brown-about 3-5 minutes. Watch closely to avoid burning.
- Serve immediately: Remove from oven carefully and serve steaming hot for the ultimate cozy indulgence.
Chef’s Notes
- Selecting the Perfect Beef Broth: For authentic warmth and richness, use a high-quality beef broth. Homemade broth offers the deepest flavor, but a premium store-bought low-sodium option works well and allows you to control seasoning.
- Caramelizing Onions: Don’t rush this step-slow, patient cooking is key. Stir frequently to prevent burning and add a splash of water or broth if onions stick.
- Cheese Crust Variations: While Gruyère is classic, Emmental or a blend of mozzarella and Swiss can create beautifully gooey results.
- Make-Ahead Tips: Soup base can be prepared a day ahead and refrigerated. Reheat gently, add toasted bread and cheese topping just before serving.
- Alcohol-Free Option: Omit the dry sherry for a strictly non-alcoholic version; adding a splash of balsamic vinegar after caramelizing enhances complexity.
Serving Suggestions
Serve your warm French onion soup in rustic ovenproof bowls to showcase the luscious golden cheese crust with perfect presentation. Garnish with fresh thyme sprigs or a sprinkle of finely chopped parsley for color and aroma.
Pair this hearty soup with a crisp green salad and crusty bread on the side for a complete comforting meal that feels like a gentle hug in a bowl.

Q&A
Q: What makes French Onion Soup such a comforting winter dish?
A: French Onion Soup is the ultimate cozy comfort food because of its rich, caramelized onions simmered to sweet perfection in a deeply flavorful beef broth. The warm, savory bowl topped with melted cheese and crusty bread invites not only warmth but a sense of home with every spoonful.
Q: Why choose a beef broth base for this soup?
A: Beef broth lends a robust and hearty foundation that perfectly complements the sweetness of slowly caramelized onions. Its natural depth enriches the soup’s complexity, making each bite bursting with layered savory goodness.
Q: How do you achieve perfectly caramelized onions?
A: Patience and low heat are key. Slowly cooking thinly sliced onions over medium-low heat allows their natural sugars to break down and turn golden brown without burning. This process can take around 40 to 50 minutes, filling your kitchen with a sweet, aromatic magic.
Q: Can you customize the soup without losing its classic essence?
A: Absolutely. While traditional French Onion Soup focuses on simple, quality ingredients, you can add a touch of fresh thyme or a bay leaf during simmering for extra herbal notes. Just avoid overpowering the onions and beef broth, which are the stars of the show.
Q: What kind of cheese works best for topping this soup?
A: Gruyère is the classic choice – it melts beautifully, offering a nutty, creamy contrast to the savory broth and tender onions. You can also use Swiss cheese or a mild mozzarella, but be sure to pick a cheese that melts smoothly and creates a golden crust when broiled.
Q: How do you get that perfect cheesy crust on top?
A: Ladle the hot soup into ovenproof bowls, place a toasted baguette slice on top of the soup, and layer generously with grated cheese. Broil for a few minutes until the cheese bubbles and turns golden brown, creating an irresistible crust that seals in the warmth.
Q: Is French Onion Soup suitable for meal prepping?
A: Yes! The flavors actually deepen if the soup is made a day ahead, allowing the onions and broth to meld beautifully. Store the soup and toppings separately, then assemble and broil just before serving for the best texture and freshness.
Q: How can I make this soup more hearty without adding meat products?
A: Incorporate additional vegetables like mushrooms or a splash of balsamic vinegar to boost umami richness. Adding a few cooked lentils or beans right before serving can also provide texture and nutrition while keeping the heartiness intact.
Q: What should I serve alongside my French Onion Soup to complete the meal?
A: A crisp green salad with a tangy vinaigrette or roasted root vegetables pairs beautifully, offering fresh or earthy contrasts to the soup’s luscious, savory richness. A fresh baguette or crusty artisan bread always makes a welcome companion, perfect for dipping.
