2. Ingredients 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 recommended for depth)
- 2 teaspoons sugar (to aid caramelization)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon fresh thyme or 1/2 teaspoon dried thyme
- 1 bay leaf
- Baguette or crusty bread, sliced
- 1 ½ cups shredded Gruyère cheese (or Swiss cheese)
3. How to Make French Onion Soup – Step-by-Step Instructions
Prepare the caramelized onions
In a large, heavy-bottomed pot or Dutch oven, melt the butter and heat the olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, for about 30-40 minutes. Be patient – this slow process is vital to develop the rich, sweet flavor of caramelized onions. During cooking, sprinkle with sugar to promote caramelization. Reduce heat if onions start to burn.
Sauté the onions to perfection
Continue cooking until the onions turn a deep golden brown, indicating the perfect caramelization. Season with salt, pepper, and thyme. Meanwhile, during the last few minutes, pour in the white wine and simmer until most of the liquid evaporates, adding complexity to the flavor.
Add broth and simmer
Pour in the beef or vegetable broth and add the bay leaf. Bring the mixture to a boil, then reduce the heat and let it simmer gently for about 20-30 minutes to intensify the flavors. Remove the bay leaf and adjust seasoning as needed.
Toast the bread
While the soup simmers, preheat your oven or toaster oven. Lightly toast the baguette slices until golden and crispy. This will serve as the perfect base for the cheesy topping.
Assemble and broil
When ready to serve, ladle the hot soup into oven-safe bowls. Top each with toasted bread slices and sprinkle generously with shredded Gruyère cheese. Place the bowls under a broiler or in an oven with a grill setting until the cheese is melted, bubbly, and slightly browned. Watch carefully so the cheese doesn’t burn.
4. Storage Tips for Leftover French Onion Soup
Store any leftover French onion soup in an airtight container in the refrigerator for up to 3 days. When reheating, do so gently on the stovetop and add fresh cheese or toasted bread if desired for the best flavor and texture.
5. Serving Suggestions
This flavorful onion soup pairs beautifully with a crisp green salad or a side of roasted vegetables. For a more substantial meal, serve with a side of crusty bread or a garlic parmesan chicken skewers. Cozy up with a warm bowl on cool autumn evenings, and consider adding a splash of brandy or sherry for a sophisticated touch.
6. Frequently Asked Questions about French Onion Soup
Can I make this onion soup vegetarian?
Absolutely! Simply substitute beef broth with a high-quality vegetable broth. The flavor remains rich and satisfying. For extra depth, add a splash of balsamic vinegar or soy sauce.
How long does it take to prepare French onion soup?
The total preparation and cooking time is approximately 1 hour, with most of that dedicated to caramelizing the onions slowly for maximum flavor.
Can I freeze French onion soup?
While it’s best enjoyed fresh, you can freeze leftovers in airtight containers for up to 2 months. Avoid freezing with cheese on top, as it may affect texture upon reheating.
