French Onion Soup Recipe: There’s something timeless about French Onion Soup. It’s a dish that’s been passed down through generations and has a place in cozy homes as well as fine dining restaurants.
Homemade French Onion Soup, with its rich, hearty broth and gooey cheese topping, is far superior to most restaurant versions. When you make it from scratch, you can control the ingredients, making it fresher and tastier.
Originally, French Onion Soup was a dish for the poor, using basic ingredients like onions and bread, but it’s now celebrated worldwide. Let’s dive into how you can make this simple yet elegant soup at home.
Ingredients for French Onion Soup
To make the perfect French Onion Soup, you’ll need:
- 5-6 large yellow onions (thinly sliced)
- 4 cups beef broth (or chicken/vegetable broth for variations)
- ½ cup dry white wine (optional)
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 1 tbsp flour (optional, for thickening)
- 1-2 cloves garlic (minced)
- Salt and pepper to taste
- French baguette (cut into thick slices)
- Gruyère cheese (or Swiss as an alternative)
Freshness and Quality of Ingredients: Why It Matters
Using fresh, high-quality ingredients can make all the difference. Fresh onions caramelize better, giving you that sweet, golden-brown base, while a good-quality broth will provide a richer depth of flavor.
Essential Tools You’ll Need
Before we begin, make sure you have the following kitchen tools:
- A large heavy-bottomed pot or Dutch oven
- Wooden spoon for stirring
- Sharp knife for slicing onions
- Oven-safe bowls for serving
- Ladle for portioning the soup
Best Pot for Making French Onion Soup
A heavy-bottomed pot, like a Dutch oven, is ideal because it evenly distributes heat and prevents your onions from burning during the caramelization process.
Step-by-Step Instructions
Step 1: Caramelizing the onions
This is the most crucial step in making French Onion Soup. Heat your pot over medium heat, and add the butter and olive oil. Once melted, add the onions and a pinch of salt to help draw out the moisture. Cook the onions, stirring frequently, for 30-40 minutes, until they turn a deep golden brown.
Tip: Don’t rush this step! Caramelizing onions slowly is what gives the soup its rich, sweet flavor. Keep stirring to avoid burning.
Step 2: Deglazing the pan
Once your onions are beautifully caramelized, it’s time to deglaze. Pour in the white wine (or water if you’re skipping the alcohol) and stir to scrape up any brown bits from the bottom of the pan. These bits are packed with flavor!
Step 3: Adding the broth
Now, add your broth. Traditional French Onion Soup uses beef broth for a rich, meaty flavor, but you can use chicken or vegetable broth if you prefer. Add the minced garlic and bring everything to a simmer.
Pro Tip: If you want a thicker soup, sprinkle in a tablespoon of flour before adding the broth.
Step 4: Simmering the soup
Let the soup simmer for about 30 minutes, allowing the flavors to meld together. Taste and adjust the seasoning with salt and pepper.
Step 5: Preparing the bread and cheese topping
While your soup simmers, prepare the bread and cheese. Cut your baguette into thick slices and toast them until they’re golden and crispy. Grate your Gruyère cheese, which melts beautifully and gives that perfect gooey finish.
Step 6: Assembling the soup for broiling
Ladle the soup into oven-safe bowls. Place a slice (or two) of toasted baguette on top, and generously sprinkle the grated Gruyère over the bread. Broil in the oven until the cheese is melted and bubbly, forming a golden crust.
Tip: Keep an eye on the soup under the broiler to prevent the cheese from burning.
Variations and Tips
Vegan and Vegetarian French Onion Soup Options
To make this soup vegan, swap the butter for plant-based margarine and use vegetable broth. You can also substitute the Gruyère with a vegan cheese that melts well.
How to Store and Reheat French Onion Soup
French Onion Soup stores well in the refrigerator for up to 3 days. Reheat it on the stove over low heat, and if you’re adding the bread and cheese topping, broil just before serving to keep it fresh and crisp.
Serving Suggestions
French Onion Soup is rich and hearty on its own, but it pairs beautifully with a fresh green salad or a light, refreshing glass of white wine. Serving it in individual bowls makes for an elegant presentation.
Tips for Making the Best French Onion Soup
- Caramelization is Key: Don’t rush caramelizing the onions. It’s the most crucial step for achieving that deep, rich flavor.
- Use Good Quality Broth: Whether beef or vegetable, a rich broth will make a noticeable difference.
- Cheese Choices: Gruyère is the most common cheese for this dish, but feel free to experiment with other melting cheeses like Swiss or mozzarella.
Common Mistakes to Avoid
- Burning the onions: Cook them low and slow to prevent bitterness.
- Using soft bread: A crusty French baguette is ideal; soft bread will turn mushy.
- Skipping the broiling step: This is what gives the soup its iconic cheese topping, so don’t skip it!
