How to Make French Onion Chicken Soup
Step 1: Sauté the Onions
Start by slicing your onions thinly; this helps them cook evenly. In a large pot, melt 4 tablespoons of butter over medium heat. Add the sliced onions and sprinkle with salt. Sauté these beauties until they turn golden brown and fragrant—this can take about 15-20 minutes. Caramelizing them develops their sweetness and forms the base flavor for our soup.
Step 2: Add Vegetables and Seasonings
Once your onions are nicely caramelized, add chopped carrots, celery, and minced garlic. Stir everything together for another few minutes until the vegetables soften slightly. Then toss in thyme, bay leaves, black pepper, and remaining salt. This step layers in more flavor as each ingredient melds beautifully.
Step 3: Cook the Chicken
Next up is adding our protein! Place the chicken into the pot and pour in the grape juice and apple juice. Allow this mixture to simmer gently until the chicken is cooked through—about 20-25 minutes should do it! Cooking it this way helps infuse all those sweet onion flavors into the chicken.
Step 4: Thicken the Soup
Remove the chicken from the pot once it’s done cooking. Shred it using two forks—it’s okay if it’s still warm—and set aside. In a small bowl, mix flour with some broth to create a slurry before whisking it back into your soup pot. This will give your soup that lovely thickness we all adore.
Step 5: Combine Everything Together
Finally, return shredded chicken to the pot along with remaining broth and let everything simmer together for an additional 10-15 minutes. This allows all those fantastic flavors to come together harmoniously. Taste it once more; if needed, adjust seasoning with more salt or pepper.
Step 6: Serve Up!
To serve, ladle hot soup into bowls and top each serving with slices of baguette soaked in Gruyère cheese (you can pop them under a broiler for a minute if you want that melty goodness). Enjoy every warm bite of this wonderful French Onion Chicken Soup—it’s like giving yourself a big hug!
Pro Tips for Making French Onion Chicken Soup
Making the perfect French Onion Chicken Soup is all about attention to detail and a few tried-and-true techniques. Here are some pro tips to ensure your soup is nothing short of spectacular!
-
Use Quality Onions: The flavor of your soup largely depends on the onions you choose. Opt for sweet yellow onions, as they caramelize beautifully, adding a rich depth to your soup.
-
Low and Slow is Key: When sautéing your onions, take your time! Cooking them over low heat allows them to caramelize properly, enhancing their sweetness and deepening the overall flavor of the soup.
-
Don’t Skip the Flour: Adding flour helps thicken the soup and gives it a creamy texture. Make sure to cook it for a minute or two before adding the broth to eliminate any raw flour taste.
-
Adjust Seasoning to Taste: Every palate is different! After the soup has simmered, taste and adjust the seasoning if needed by adding more salt or pepper for that perfect balance.
-
Let it Rest: If you can, let your soup sit for a little while before serving. This resting period allows the flavors to meld together beautifully, creating a more harmonious dish.

- Croutons: Top each serving with homemade or store-bought croutons for added crunch and texture.
