Gluten-Free French Onion Soup Recipe
This GF soup is such a classic comfort food that warms you from the inside out, and yes, it would be a deal breaker if I could not enjoy it when navigating a gluten-free journey. Luckily, we do not need to place this in the once-loved folder and can enjoy it with a few easy adjustments.
I’ve spent countless hours perfecting the balance of savory broth, sweet caramelized onions, and that oh-so-important gooey cheese topping. And let me tell you, getting the onions right is key. They need to be cooked slowly until they reach that perfect golden-brown sweetness. Patience is your friend here! So take the time it needs. I promise it will be so worth it.
And yes, the broth is a combination of beef and chicken. It gives a rich and hearty blend, giving this soup so much flavor that it is to die for. And, of course, no GF French Onion Soup is complete without the slice of gluten-free baguette topped with melted Gruyère cheese, broiled to bubbly perfection. It is really so yum!

Brown Sugar - Helps in faster caramelization of the onions, adding sweetness to the broth.
Salt - Balances the sweetness of the onions.

Worcestershire Sauce - This is also a flavor booster.
Gluten-Free Beef Broth and Chicken Broth - Use a good quality beef broth as this is the base of the soup.
Fresh Thyme - This is for flavor and works well with caramelized onions. It is also added on top as a garnish.
Ground Black Pepper - Adds to the flavor of the soup too.

Equipment Needed for This Gluten-Free French Onion Soup
Heavy Bottomed Pot or Dutch Oven - These pots ensure you have an even heat distribution for the perfect caramelization of onions.
