What You’ll Need
To whip up this delectable French onion soup, gather the following ingredients:
- Onions: 6 cups thinly sliced
- Butter: 2 tablespoons
- Olive oil: 2 tablespoons
- Fresh thyme: 6 sprigs (or 1 teaspoon dried thyme)
- Bay leaf: 1
- White wine: ½ cup
- Beef broth: 4 cups (high-quality for best results)

Step-by-Step Instructions
Caramelize the Onions
Start by heating the butter and olive oil in a large pot over medium heat. Add the sliced onions, a sprinkle of salt, and cook them low and slow for about 30–40 minutes, stirring occasionally. The goal here is to achieve that deep golden color and sweet flavor.
Deglaze and Simmer
Once the onions are beautifully caramelized, add the white wine to deglaze the pot. Scrape any browned bits off the bottom, letting all those flavors blend. Toss in the thyme and bay leaf, and pour in the beef broth. Simmer this masterpiece for another 15–20 minutes, then remove the bay leaf and thyme.
Prepare for Broiling
While your soup simmers, prepare your baguette slices by toasting them until golden. This will lend a satisfying crunch to your dish!
Broil the Soup
Ladle the soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl and generously sprinkle the grated cheese over the bread. Pop these under the broiler for 3–5 minutes until the cheese is bubbly and slightly browned.
Garnish and Serve
Once your soup is out of the oven, let it cool for a moment. A sprinkle of fresh thyme on top can add a lovely aromatic touch. Serve hot and enjoy!
Best Ways to Enjoy It
This French onion soup shines as a standalone meal, but it pairs exceptionally well with a simple side salad or a platter of charcuterie. Consider serving it alongside crusty artisan bread or fresh fruit to create a delightful contrast. For a cozy gathering, why not follow it with some light desserts like fruit tarts or chocolate mousse?
Storage and Reheating Tips
If you’re lucky enough to have leftovers, storing them properly is key. Transfer the soup to an airtight container and refrigerate. It should stay fresh for about 3–4 days. To reheat, simply warm it on the stove over low heat. For leftovers, avoid broiling if you’re unsure about the cheese holding up well after reheating. You can always re-toast fresh bread and add new cheese for that delightful broiled finish right before serving.
Helpful Cooking Tips
To elevate your French onion soup even further, consider these pro tips:
- Choose the Right Onions: Sweet yellow onions are ideal for creating that classic flavor, but you can mix in some red or shallots for added depth.
- Patience is Key: Don’t rush the caramelization process. The more slowly you cook the onions, the sweeter and more flavorful they become.
- Homemade Broth: If you have the time, making your own beef broth can turn this into an even more impressive dish.
Creative Twists
Looking to shake things up? Here are some delightful variations you can try:
- Cheese Swaps: Experiment with different melting cheeses like Fontina or Swiss for unique flavor profiles.
- Add Protein: For a heartier soup, consider adding some shredded chicken or sauteed mushrooms.
- Herbs and Spices: Fresh rosemary or a dash of sherry can complement the flavors beautifully.
Common Questions
What’s the prep time for this recipe?
Expect about 10-15 minutes to slice your onions and prepare the other ingredients. The cooking time, including caramelizing and simmering, will take roughly an hour.
Can I use vegetable broth instead of beef broth?
Certainly! Vegetable broth is a great substitute if you’re looking for a lighter or vegetarian option. Just note that it will alter the flavor slightly.
How long can I store leftovers?
Leftover French onion soup can be refrigerated for 3-4 days. It’s best enjoyed fresh, but reheating works well too!
With its rich flavors and comforting essence, this Easy French Onion Soup is bound to become a staple in your kitchen. Enjoy the warmth and simplicity it brings to your table!
