Introduction
French Onion Soup is a rich, comforting classic known for its deep caramelized onion flavor, savory beef broth, toasted bread, and golden melted cheese on top. Warm, cozy, and full of flavor, it’s a timeless dish perfect for chilly days or elegant dinners.
Ingredients
4–5 large yellow onions, thinly sliced
3 tablespoons butter
1 tablespoon olive oil
1 teaspoon sugar (optional, helps caramelize)
3 cloves garlic, minced
4 cups beef broth
1 cup chicken broth (optional for balance)
½ cup dry white wine (optional)
1 teaspoon fresh thyme (or ½ teaspoon dried)
Salt and black pepper to taste
Baguette slices, toasted
1–1½ cups shredded Gruyère or Swiss cheese
Instructions
Melt butter and olive oil in a large pot over medium heat.
Add sliced onions and cook slowly for 25–35 minutes, stirring often, until deeply golden and caramelized.
Add garlic and cook for 1 minute.
Stir in wine (if using) and simmer for 2–3 minutes.
Add broth, thyme, salt, and pepper. Simmer for 15–20 minutes.
Ladle soup into oven-safe bowls.
Top each bowl with toasted baguette slices and generous shredded cheese.
Broil for 2–4 minutes until cheese is melted and bubbly golden.
Serve hot and enjoy carefully—it’s very hot!
How to Make It Perfect
Cook onions slowly—rushing prevents deep flavor.
Use good-quality broth for best taste.
Broil just until golden, not burnt.
Use oven-safe bowls to avoid cracking.
Variations
Vegetarian: Use vegetable broth instead of beef broth.
Extra Cheesy: Add mozzarella for extra stretch.
Herb Boost: Add bay leaf while simmering.
Lighter Version: Use less cheese and whole-grain bread.
Tips
Slice onions evenly for consistent cooking.
Stir frequently during caramelizing to prevent burning.
If onions brown too fast, lower the heat.
Let soup rest 5 minutes after broiling before serving.
