How to Make Irresistible French Onion Chicken Soup: Made Twice in a Week!

1. In a large heavy-bottomed pot, heat butter and olive oil over medium heat until melted and shimmering.
2. Add the sliced onions and a pinch of salt, then cook slowly, stirring frequently, for 35-40 minutes until the onions are deeply caramelized and golden brown.
3. If using, pour in the white wine to deglaze the pot, scraping up any browned bits; cook for 3-5 minutes until the liquid reduces by half.
4. Add the chicken broth, shredded chicken, thyme, and bay leaf. Bring to a gentle simmer and cook uncovered for 10 minutes to meld flavors.
5. Season the soup with salt and freshly ground black pepper to taste, then remove the bay leaf.
6. Preheat your oven’s broiler. Ladle the soup into oven-safe bowls, place a toasted baguette slice on top of each, and sprinkle with shredded Gruyere cheese.
7. Place the bowls on a baking sheet and broil for 3-5 minutes until the cheese is melted, bubbly, and golden brown.
8. Carefully remove from the oven (the bowls will be hot) and let cool slightly before serving.

Tips for the Best Results

• Take your time caramelizing the onions; low and slow is the key to deep sweetness.
• Use cooked chicken from a rotisserie or leftovers to save time and add flavor.
• Don’t skip the toasting of the baguette slices—they provide a satisfying crunch under the cheese.
• Gruyere cheese melts beautifully and adds a nutty flavor, but Swiss or mozzarella can work in a pinch.
• Cook the soup uncovered during simmering to concentrate the flavors.

Storage and Reheating

Store any leftover French onion chicken soup in an airtight container in the refrigerator for up to 3 days. When ready to enjoy again, reheat gently on the stovetop over low heat, stirring occasionally.

You can freeze the soup without the bread and cheese topping for up to 3 months. Thaw overnight in the refrigerator and reheat on the stovetop. Add fresh toasted baguette slices and cheese before serving to keep them crisp.

Frequently Asked Questions

Can I use different types of cheese for this soup?

Absolutely! While Gruyere is traditional and melts beautifully, you can substitute Swiss, mozzarella, or even fontina depending on your preference. Just choose a cheese that melts well and adds a mild, creamy texture.

Is it necessary to use white wine in the recipe?

The white wine adds a lovely depth of flavor and acidity but is optional. If you prefer to avoid alcohol, omit it and simply deglaze the pot with a splash of extra chicken broth.

How can I make this soup vegetarian?

To make a vegetarian version, substitute the chicken broth with vegetable broth and replace the chicken with hearty mushrooms or lentils for texture. The caramelized onions will still give you that rich, savory base.

What’s the best way to serve this soup?

This soup is perfect as a main dish with a crisp green salad or as a starter for a larger meal. Serve it hot with plenty of crusty bread to soak up the flavorful broth and melted cheese.
