How to Make French Onion Chicken Soup
Step 1: Sauté the Onions
Start by slicing your onions thinly. In a large pot, melt 4 tablespoons of unsalted butter over medium heat. Add the sliced onions along with thyme, bay leaves, salt, and pepper. Cook until they are deeply caramelized—this step is crucial as it brings out their natural sweetness and forms the base of your soup’s flavor.
Step 2: Add Vegetables
Once your onions are beautifully golden brown (about 30 minutes), stir in chopped carrots, celery, and minced garlic. Sauté these veggies until they soften; this adds depth to your soup and balances out all those rich flavors.
Step 3: Brown the Chicken
Next up is adding your chicken! Push the vegetables aside in the pot and add them in whole. Brown each side for about 5 minutes; this locks in moisture and enhances flavor before simmering.
Step 4: Deglaze with Juices
Pour in the dry white grape juice and apple juice to deglaze your pot. Scrape up any flavorful bits stuck at the bottom—it’s all about building flavor here! Allow it to simmer for another few minutes.
Step 5: Thicken Your Soup
Sprinkle in flour while stirring continuously; this will help thicken your soup later on. Gradually pour in low-sodium chicken broth while still mixing until everything is combined smoothly.
Step 6: Simmer Away
Bring your soup to a gentle boil before reducing heat to low. Let it simmer uncovered for about an hour. This simmering time allows all those wonderful flavors to meld beautifully together while making your kitchen smell divine!
Step 7: Serve with Style
When ready to serve, ladle hot soup into bowls topped with slices of toasted baguette and sprinkle Gruyère cheese generously on top. Pop them under the broiler until bubbly—oh my goodness!
This French Onion Chicken Soup will soon become a cherished recipe in your home just like it has mine! Enjoy every warm bite!
Pro Tips for Making French Onion Chicken Soup
Making a delicious French Onion Chicken Soup is all about the little details, so here are some pro tips to ensure your soup turns out perfectly every time!
-
Choose the right onions: Yellow onions are ideal for this soup because they caramelize beautifully, bringing out their natural sweetness. This sweetness is key to achieving that rich, comforting flavor.
-
Don’t rush the caramelization: Take your time when cooking the onions. It may take longer than you expect, but allowing them to slowly caramelize creates a deep, complex flavor that elevates the entire dish.
-
Use low-sodium broth: Opting for low-sodium chicken broth allows you to control the saltiness of your soup better. You can always add more salt at the end if needed but starting with less prevents over-seasoning.
-
Toast your bread: For added texture and flavor, toast your baguette slices before adding them atop the soup. This will prevent them from becoming too soggy and enhance their crunchiness.
-
Experiment with cheeses: While Gruyère is a classic choice, feel free to mix in other melting cheeses like mozzarella or even a sprinkle of parmesan for an extra flavor kick!
