Do you miss French Onion Soup? Onion soup recipe itself is really easy to adapt to be gluten free...what has been missed is that crispy baguette that floats on top of the soup under all of the melty cheese!
Well, I found the perfect solution! Milton's Gluten Free Crackers!!
You may ask how crackers make this soup so good. Milton's Gluten Free Crispy Sea Salt Crackers are the perfect substitute for the crispy crouton in traditional French onion soup recipes."
Milton's gluten free crackers come in several varieties including:
- Sea Salt
- Cheddar Cheese
Milton's certified Gluten Free crackers are so tasty, they make munching a happy experience regardless of dietary restriction or palette preference. Plus, they’re Non-GMO, Project Verified, and they do not contain wheat, nuts, or conventional fillers – so they’re better for both you and the environment.
If you have been following my blog for awhile, you know I LOVE brands who give back through charitable giving. I was a non-profit fundraiser for many years and when companies are there to help, everyone wins!!
Milton’s also supports community causes like Celiac-related hospital advocacy, autism support groups and children’s charities, that promote health for our families and communities.
Now let's talk about this soup. It is crazy good and the men in the house absolutely devoured it! And yes, you should also know my "picky one" would only eat the melted cheese. This is forever my challenge...getting her to try (and like) new foods!
French onion soup is a meat broth-based soup with that famous crouton and melty cheese on top. As the name implies, it is from France, and it is usually served as a starter.
There are many variations, and my gluten free version of French onion soup is so easy to make for yourself!
What is the best onion to use for this soup?
My favorite onion to use is a large sweet onion. Some stores have Hawaiian sweet onions. Their mellow sweetness adds to the caramelized flavor of this soup. You can also use red onion, which adds a deeper onion flavor.
Yellow onions are just okay...they give off an initial bitter taste, which my son didn't like as much.
How to caramelize onions:
The first step is to melt a stick of butter in a pan.
Add the onions and sauté 5 minutes until the onions become soft.
Add coconut sugar and spices. I normally wouldn't add sugar to a soup recipe, but the sugar helps the onions caramelize. Cover and allow the onions to cook for 20 minutes, or until they are caramelized like the next picture.
Add the caramelized onions to a soup pot.
Pour in the beef broth. Add two bay leaves and thyme. Cover and allow to simmer for one hour.
Use a ladle to fill bowls with the gluten free French onion soup.
This is my favorite part. Grab a bag of Milton's Gluten Free Sea Salt Crackers. Take about 4 or 5 crackers and place them on top of the onion soup.
Top with a thick slice of gruyere cheese. Place the soup bowls in a baking dish and place under a broiler until the cheese gets all melty.
