How to Make French Onion Chicken Soup
Step 1: Sauté the Onions
Start by melting 4 tablespoons of butter in a large pot over medium heat. Add your sliced onions along with the dried thyme, bay leaves, 1 teaspoon of kosher salt, and black pepper. Stir occasionally and cook until the onions are beautifully caramelized—this usually takes about 30 minutes. This step is crucial because sautéing the onions brings out their natural sweetness, which forms the base of our delicious soup.
Step 2: Add Vegetables
Once your onions are golden brown and fragrant, add chopped carrots and celery into the mix. Continue cooking for another 5-7 minutes until they soften. Then toss in minced garlic and let it cook for about 1 minute longer until aromatic. Adding these vegetables not only enhances flavor but also boosts nutrition!
Step 3: Incorporate Chicken
Next up, add your chicken breasts or thighs into the pot. Let them cook for about 5 minutes on each side until they’re lightly browned. This will help seal in their juices. The wonderful thing about this step is that you’re building layers of flavor that will make your soup even more comforting.
Step 4: Deglaze with Juices
Pour in the dry white grape juice and dry apple juice to deglaze the pot, scraping any brown bits off the bottom. Let it simmer gently for about 5 minutes; this adds depth to our soup’s flavor profile.
Step 5: Create the Broth
Sprinkle in flour evenly over everything in the pot while stirring constantly; this will help thicken your soup later. Gradually stir in low-sodium chicken broth while ensuring there are no lumps left from the flour. Bring everything to a gentle boil before reducing heat to low. Cover and let simmer for at least an hour; this allows all those lovely flavors to meld together beautifully.
Step 6: Serve with Bread and Cheese
When ready to serve, ladle your warm soup into bowls. Top each serving with slices of baguette and sprinkle Gruyère cheese on top. You can pop them under a broiler briefly if you like your cheese bubbly! Enjoy every spoonful of this hearty French Onion Chicken Soup—it’s truly a hug in a bowl!
Pro Tips for Making French Onion Chicken Soup
Making the perfect French Onion Chicken Soup is all about enhancing flavors and textures, so here are a few tips to help you create a dish that’s comforting and delicious!
-
Slice Onions Thinly: The thinner the onion slices, the more evenly they will caramelize, resulting in a rich and sweet flavor that forms the base of your soup.
-
Low and Slow Cooking: Allow the onions to cook over low heat for an extended period. This method develops their sweetness and deepens their color, creating that classic French onion taste.
-
Deglaze with Grape Juice: Using dry white grape juice instead of wine adds a unique sweetness and acidity without overpowering the soup, making it a great alternative for those avoiding alcohol.
-
Use Fresh Herbs: Incorporating fresh thyme or parsley as a garnish not only enhances the appearance but also adds a burst of freshness that balances the richness of the soup.
-
Broil for Extra Flavor: If you want to take your soup up a notch, place it under the broiler after adding cheese to the bread. This will create a bubbly, golden crust that’s irresistible!
How to Serve French Onion Chicken Soup
Serving your French Onion Chicken Soup is just as important as making it! Here are some ideas to present this cozy dish beautifully.
Garnishes

- Croutons: Homemade or store-bought croutons can add an extra crunch on top, providing texture contrast against the smooth soup.
- Shaved Parmesan Cheese: While Gruyère is traditional, adding some shaved Parmesan on top gives an additional layer of flavor that complements the other cheeses.
Side Dishes
- Simple Green Salad: A light green salad made with mixed greens, cherry tomatoes, and a tangy vinaigrette offers a refreshing contrast to the hearty soup.
- Garlic Bread: Crispy garlic bread is perfect for dipping into your soup and soaking up all those delicious flavors.
- Roasted Vegetables: Seasonal roasted vegetables like carrots, zucchini, or brussels sprouts bring added nutrition and sweetness that pairs wonderfully.
