Ingredients You’ll Need for French Onion Chicken Soup
The magic of this French Onion Chicken Soup Recipe lies in using simple, humble ingredients that transform into something extraordinary when cooked with love and patience. Every element adds depth, comfort, and balance. Let’s break it down:
For the Soup:
- Yellow onions (3 pounds, about 4 large or 6 medium): The star of the show! Onions are slowly caramelized until they’re golden and sweet, giving the soup its rich flavor. Don’t rush this step—it’s where the heart of the recipe develops.
- Unsalted butter (6 tablespoons, divided): Butter adds richness and helps the onions turn perfectly golden. Using unsalted allows you to control the seasoning better.
- Dried thyme (1 teaspoon): A classic herb that pairs beautifully with onions and chicken, giving the soup that cozy, homemade taste.
- Bay leaves (2 dried): These little leaves infuse a subtle earthiness. Just remember to fish them out before serving.
- Kosher salt (2 1/2 teaspoons, divided, plus more as needed): Essential for bringing out the sweetness of the onions and seasoning the chicken evenly.
- Freshly ground black pepper (1/2 teaspoon): Adds warmth and a little bite to balance the sweetness of the onions.
- Carrots (3 medium): Sliced into rounds, they bring color, a hint of natural sweetness, and extra nutrients to the soup.
- Celery (3 medium stalks): Classic soup vegetable, celery gives the broth depth and a touch of freshness.
- Garlic cloves (3, minced): Garlic rounds out the flavor, adding that comforting aroma we all know and love.
- Chicken (2 pounds, boneless and skinless breasts or thighs): This turns French onion soup from a starter into a full meal. Thighs give a slightly richer flavor, while breasts are leaner.

- White grape juice (3/4 cup) + apple cider vinegar (1 tablespoon): In place of wine or sherry, this combo keeps the soup halal while still adding brightness and depth. It gives you that tangy lift without alcohol.
- All-purpose flour (1/4 cup): Helps thicken the broth so it’s rich and satisfying.
- Low-sodium chicken broth (6 cups): The base of the soup. Using low-sodium lets you season to taste without overpowering the delicate onion sweetness.
For the Cheesy Toasts (Optional but Irresistible):
- Baguette (1/2, sliced into thick pieces): Provides the perfect sturdy base for gooey cheese.
- Gruyère cheese (2 ounces, shredded): Melts into a golden, bubbly topping that makes this soup feel like a cozy French café experience at home. If Gruyère isn’t handy, try Swiss, provolone, or mozzarella.
How to Make French Onion Chicken Soup
Making this French Onion Chicken Soup Recipe is truly a labor of love, but don’t worry—it’s not complicated. The key is patience, especially when it comes to caramelizing those onions. Follow these detailed steps and you’ll have a pot of pure comfort ready to serve.
Step 1: Slice and Prepare the Onions
Peel, halve, and thinly slice 3 pounds of yellow onions (about 10 cups). It may feel like a mountain of onions, but trust me—they’ll cook down dramatically. The more patient you are here, the sweeter and richer your soup will be.
Step 2: Caramelize the Onions
In a large Dutch oven or heavy-bottomed pot, melt 4 tablespoons of butter over medium heat. Add the sliced onions, thyme, bay leaves, 1 1/2 teaspoons salt, and black pepper. Cook slowly, stirring often, for 35 to 45 minutes until the onions are soft, golden, and deeply caramelized.
👉 Pro tip: Keep scraping the bottom of the pot with a wooden spoon to prevent burning. This is where the soul of French onion flavor comes alive.
Step 3: Add the Vegetables
While the onions are working their magic, prep your carrots, celery, and garlic. Stir them into the pot along with the remaining butter. Cook another 5 minutes, until the veggies are just starting to soften. This step layers in that homemade flavor that makes the soup taste like it simmered all day.
Step 4: Add the Chicken and Seasonings
Season 2 pounds of boneless chicken breasts or thighs with the rest of the kosher salt. If you’re using thick chicken breasts, slice them in half (butterfly them) so they cook evenly. Nestle the chicken right into the pot, ready to soak up all that caramelized onion flavor.
Step 5: Deglaze with Halal Substitute
Instead of wine or sherry, pour in 3/4 cup white grape juice and 1 tablespoon apple cider vinegar. This halal swap gives you the same brightness and tang. Stir, scraping up all those tasty browned bits from the bottom of the pot. Cook until most of the liquid evaporates—just a few minutes.
Step 6: Build the Broth
Sprinkle in 1/4 cup all-purpose flour and stir constantly for about 1 minute. This cooks off the raw flour taste and helps thicken the soup later. Slowly pour in 6 cups chicken broth while stirring. Turn the heat up to medium-high until the broth starts to simmer.
Step 7: Simmer and Cook the Chicken
Reduce the heat to low and let the soup gently simmer for about 10–20 minutes, depending on the chicken cut you’re using. Breasts take a little longer than thighs. Cook until the chicken reaches an internal temp of 165°F.
Step 8: Shred the Chicken
Transfer the chicken to a cutting board and shred it with two forks into bite-sized pieces. Return the chicken to the pot, discard the bay leaves, and give everything a good stir. Taste and adjust the seasoning if needed.
Step 9: Make the Cheesy Toasts (Optional but Worth It!)
Preheat your broiler. Slice half a baguette into thick pieces, place them on a baking sheet, and sprinkle generously with shredded Gruyère. Broil for 30 seconds to 1 minute, just until bubbly and golden.

Step 10: Serve and Enjoy
Ladle the hot soup into bowls and top each serving with a cheesy toast. The bread will soak up the broth while the cheese melts into gooey goodness. This is the moment where your kitchen officially smells like a French bistro—without ever leaving home.
Tips and Tricks for Perfect French Onion Chicken Soup
- Patience is key – Let the onions get deep golden. That’s where the magic happens.
- Don’t rush the chicken – Use a thermometer to avoid overcooking.
- No Gruyère? Try mozzarella or provolone for a melty alternative.
- Make it ahead – The flavors develop beautifully after resting overnight.
- Freezer tip – Freeze without the cheesy toasts for up to 3 months.
Fun fact: The first time I made this, my youngest called it “the soup that smells like happiness.” And honestly? He nailed it.
Storage for French Onion Chicken Soup
- Fridge: Keeps in an airtight container up to 4 days.

FAQs
Q: Can I use rotisserie chicken?
Yes! Just add it after the broth simmers. It’s a great shortcut.
Q: What bread works best for cheesy toasts?
A sturdy baguette or sourdough holds up beautifully.
Q: Can I make this in a slow cooker?
You can, but caramelizing onions on the stove first makes all the difference.

Instructions
1. Peel, halve, and thinly slice the onions (about 10 cups total).
2. Melt 4 tablespoons butter in a Dutch oven over medium heat. Add onions, thyme, bay leaves, 1 1/2 teaspoons salt, and black pepper. Cook, stirring often, until soft and amber brown, 35 to 45 minutes.
3. Meanwhile, peel and slice carrots and celery into 1/4-inch pieces, and mince garlic. Combine in a bowl.

Notes
For best flavor, take time to deeply caramelize the onions until amber brown.
Store leftovers in an airtight container in the fridge for up to 4 days, or freeze for up to 3 months.
Cheesy toasts are optional but highly recommended for that classic French onion flair.
Use a dry white wine like Sauvignon Blanc or Pinot Grigio.
