Ingredients
Method
- Melt butter and olive oil over medium heat in a large Dutch oven or heavy-bottom pan. Once heated, add the sliced onion, minced garlic, brown sugar, and salt to the pan.
- Sauté until the onions are soft and caramelized, about 30-35 minutes. Keep an eye on the onions and stir frequently. Add a tablespoon of water if necessary to prevent sticking.
- When the onions are caramelized, sticky, and golden brown, sprinkle the gluten-free flour and stir well until fully incorporated.
- Once the flour is mixed well with the onions, pour the dry white wine and Worcestershire sauce into the pan and stir again.
- Add the beef broth. Simmer for 10-15 minutes until the broth thickens. Season with more salt and pepper if necessary.
- Take a ladle of the soup and pour it into 4 oven-safe bowls. Broil in the oven for 2-3 minutes until the cheese is beautifully brown and fully melted. Serve immediately while hot and enjoy.
Notes
– Use a good quality dry white wine that you’d enjoy drinking. This significantly impacts the depth of flavor in your French onion soup.
– For food safety, ensure your soup reaches a gentle simmer throughout. Any meat-based broths should be heated thoroughly to at least 165°F (74°C) if not already boiling.
– Storage: Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop. Add the cheese and baguette just before serving and broiling.

The Technique That Makes It
The key to a successful gluten-free French onion soup lies in the caramelization of the onions. This process enhances the natural sweetness of the onions, creating a rich, deep flavor that serves as the soup’s foundation. Start by cooking the onions slowly in a combination of butter and olive oil over medium-low heat. This allows for even cooking and prevents burning. The addition of brown sugar helps to expedite the caramelization process, enhancing the sweetness further. As the onions cook down, they will release moisture, which is essential for developing the soup’s body. Once the onions are beautifully caramelized, deglazing the pot with dry white wine adds acidity and complexity, lifting the flavors. The gluten-free flour acts as a thickening agent, ensuring the soup has a satisfying texture without compromising its gluten-free nature.
Troubleshooting
- Problem: Onions are not caramelizing properly.
Fix: Ensure you are cooking the onions on medium-low heat. If the heat is too high, they will burn rather than caramelize. Stir frequently to prevent sticking. - Problem: Soup is too thin.
Fix: If the soup lacks body, you can add a bit more gluten-free flour to thicken it. Mix it with a small amount of broth before adding it to the pot to avoid clumping. - Problem: Soup lacks depth of flavor.
Fix: Taste and adjust the seasoning. Adding a bit more Worcestershire sauce or a splash of balsamic vinegar can enhance the flavor profile significantly. - Problem: Onions taste bitter.
Fix: If the onions have been cooked too quickly, they may taste bitter. Reduce the heat and add a splash of water to deglaze the pan, scraping up any burnt bits.
Substitutions
- Butter: Use ghee or coconut oil for dairy-free options while maintaining richness.
- Gluten-free flour: Almond flour or cornstarch can be used as a thickening agent, though they will alter the texture slightly.
- Dry white wine: Substitute with apple cider vinegar or lemon juice mixed with water for a non-alcoholic version.
- Gluten-free beef broth: Chicken broth or vegetable broth can be used for a lighter flavor, though it may change the overall taste.
Pro tips
