Gluten free French Onion Soup

gluten free french onion soup

Gluten free French onion soup is here and it’s packed with flavor.

Ah, French onion soup. It seems to be everywhere theses days, and for good reason. It’s easy to make and uses simple ingredients to achieve a delicious comfort food.

Onions and cheese are the stars of the show for this soup. Caramelizing the onions enhances their sweetness and creates a broth with wonderful flavor and depth. I love the slight tang the white wine gives the broth and the herby note from the thyme.

A traditional French onion soup calls for Gruyere or Swiss cheese, but I love topping mine with a mild Provolone. You can use whichever cheese you prefer as long as it melts nicely. The Gooey cheese is one of my favorite parts of this soup.

The main difference with normal french onion soup and Gluten free french onion soup is the bread you use. Texture is a big factor when it comes to choosing a bread for the soup. You need to like the texture when it’s soggy because in french onion soup the bread slice soaks up all that yummy broth and gets soggy. You also want to use bread that will not completly fall apart after it’s been soaked because you need the structure of the bread to hold the cheese above the soup so it gets bubbly and gooey.

What bread should you use?

I like Franz gluten free bread. I just dry out a few slices in the oven before using it for French onion soup. It’s a readily available brand in my area and I like it’s texture, even when soggy, and it tastes great.

I love making this soup on a weekend when I’m lounging around and want something rich and flavorful. I’ll sit on my kitchen counter and read a book between stirring the onions. It’s relaxing and makes me feel less impatient for the soup to be done.

I save any extra broth I have and use it in other recipes like pastas or for topping meats (hello pork chops with a french onion sauce). It gives an amazing flavor and depth to other dishes, and I like that nothing is wasted.

If you want to add even more onion flavor try using my onion oil instead of coconut oil in the recipe or drizzle it on top just before serving.

This classic comfort food is easy to make. The caramelized onions create a sweet and salty broth that tastes amazing with the melted cheese.
