2. Ingredients for French Onion Soup

• 4 large yellow onions, thinly sliced
• 4 tablespoons butter
• 2 tablespoons olive oil
• 1 teaspoon sugar (to enhance caramelization)
• 4 cloves garlic, minced
• 8 cups beef broth or vegetable broth for a vegetarian version
• 1/2 cup dry white wine (optional but recommended)
• 1 teaspoon fresh thyme or 1/2 teaspoon dried thyme
• Salt and freshly ground black pepper to taste
• Baguette slices, toasted
• 2 cups grated Gruyère cheese (or Swiss cheese as a substitute)

3. Step-by-Step Instructions to Make French Onion Soup

Preparation of Caramelized Onions

Start by heating the butter and olive oil in a large, heavy-bottomed pot. Add the sliced onions and sugar. Cook on low to medium heat, stirring occasionally, until the onions are deeply golden and caramelized, about 30-40 minutes. Proper caramelization is key to developing the rich, sweet onion flavor that defines this French onion stew.

Adding Aromatics and Deglazing

Once the onions are caramelized, add the minced garlic and cook for another minute until fragrant. Next, pour in the white wine (if using) and scrape up any browned bits from the bottom of the pot—this step adds depth to the broth. Let the wine reduce by half.

Simmering the Soup

Add the broth, thyme, salt, and pepper to the pot. Bring everything to a gentle simmer and cook uncovered for 20-30 minutes to meld the flavors. Taste and adjust seasoning as needed.

Preparing the Toasted Baguette Slices

While the soup simmers, toast the baguette slices until crispy. You can do this in a toaster or under the broiler. Once toasted, set aside.

Assembling and Melting Cheese

Pour the hot soup into ovenproof bowls. Top each bowl with toasted baguette slices, then generously sprinkle grated Gruyère cheese over the bread. Place the bowls under a broiler (or in a toaster oven) until the cheese is bubbly and golden, about 3-5 minutes.

4. Storage Tips for Leftover French Onion Soup

Allow the soup to cool completely before transferring to airtight containers. Store in the refrigerator for up to 3 days. To reheat, gently warm on the stove over medium heat, adding a splash of broth if necessary to loosen the soup. For best results, reheat only the soup, as topping the bread and cheese before storing may result in soggy bread upon reheating.

5. Serving Suggestions for French Onion Soup

This fall comfort soup pairs beautifully with a fresh green salad or roasted vegetables for a complete meal. For added flavor, serve with a side of creamy spinach and mushroom pasta or garlic parmesan chicken skewers. As a delightful beverage accompaniment, try a glass of crisp white wine or hot apple cider to enhance the cozy dining experience.
