How to Make French Onion Chicken Soup
Step 1: Sauté the Onions
Start by slicing your yellow onions thinly. Heat 4 tablespoons of butter in a large pot over medium heat. Add the onions and cook them slowly until they turn golden brown and caramelized—this process takes around 30-40 minutes. Sautéing them brings out their natural sweetness and gives your soup an incredible depth of flavor.
Step 2: Add Vegetables and Seasonings
Once your onions are beautifully caramelized, add chopped carrots, celery, and minced garlic to the pot. Stir everything together and cook for another 5-7 minutes until the vegetables soften. This step adds layers of flavor to your soup!
Step 3: Incorporate Chicken and Liquids
Next, stir in your chicken pieces along with grape juice and apple juice. This unique blend adds sweetness without being overpowering. Afterward, sprinkle flour over everything and mix well before adding chicken broth gradually while stirring continuously.
Step 4: Simmer Away!
Add bay leaves, thyme, salt, and pepper to season. Bring everything to a gentle boil then reduce heat to low. Cover the pot and let it simmer for about 45 minutes; this allows all those wonderful flavors to meld together beautifully.
Step 5: Prepare for Serving
When ready to serve, remove the bay leaves from the pot. Ladle your delicious soup into bowls and top each serving with toasted baguette slices and a generous sprinkling of Gruyère cheese. Pop them under the broiler just long enough for that cheese to melt into gooey perfection!

Pro Tips for Making French Onion Chicken Soup
