2. Ingredients Needed for French Onion Soup

• 4 large yellow onions, thinly sliced
• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 4 cups beef broth (or vegetable broth for a vegetarian option)
• 1 cup dry white wine (optional but adds depth)
• 2 teaspoons sugar (for caramelizing the onions)
• 1 teaspoon fresh thyme leaves or ½ teaspoon dried thyme
• Salt and freshly ground black pepper to taste
• Baguette slices, toasted
• 2 cups grated Gruyère cheese or Swiss cheese

3. Step-by-Step Instructions for Making Classic Onion Soup

Prepare and caramelize the onions

Start by peeling and thinly slicing the onions. In a large, heavy-bottomed pot, melt the butter with olive oil over medium heat. Add the sliced onions and cook slowly, stirring occasionally, until they become soft, golden, and caramelized—about 30-40 minutes. During this process, sprinkle with sugar every 10 minutes to enhance caramelization.

Add the liquids and herbs

Once the onions are beautifully caramelized, stir in the thyme, salt, and pepper. Pour in the white wine (if using) and cook until the alcohol evaporates, about 2-3 minutes. Add the beef or vegetable broth, bring to a simmer, and let it cook for another 20 minutes to meld the flavors.

Prepare the bread toppings

While the soup simmers, toast the baguette slices until crispy. For added flavor, you can rub them with garlic or brush with a little olive oil before toasting.

Assemble and melt the cheese

Ladle the hot caramelized onion soup into oven-safe bowls. Top each with a toasted baguette slice and generously sprinkle with grated Gruyère cheese. Place the bowls under a broiler until the cheese bubbles and forms a golden crust.

4. Storage Tips for Leftover Onion Soup

If you have leftovers, allow the soup to cool completely before transferring it to airtight containers. Store in the refrigerator for up to 3 days. To reheat, gently warm the soup on the stove over low heat, adding a splash of broth or water if it has thickened. For the cheese topping, reheat the soup and add fresh toasted bread and cheese just before serving to maintain the crispy, cheesy crust.

5. Serving Suggestions for the Perfect Onion Soup Experience

This comforting onion soup pairs beautifully with a simple green salad or a platter of assorted cheeses. For a heartier meal, serve it alongside roasted vegetables or a crusty artisan loaf. To enhance your cooking experience, consider using high-quality cookware like the T-fal 14-Piece Hard Anodized Nonstick Cookware Set for easy sautéing and simmering.

Can I freeze French Onion Soup?
