Before I get to the recipe, I have a few tips for you.

The secret to toasting gluten free bread so it won’t dry out

We want to toast our bread slices before placing them atop each bowl of soup. But toasting gluten free bread slices in the oven, has a tendency to dry them out. Why? Maybe because they lack the gluten protein, I’m not sure.

However, grilling in a pan with lots of butter, produces soft tasty gluten free toasts!

I’ll show you my easy method in the instructions below. Trust me, you’re in for a treat!

How to make French onion soup low carb

If you’re a low-carber like me, you can skip the flour, the baguette, and the wine. With only 6.9 net carbs, you can enjoy all the flavors of this healthy soup.

It’s so toasty good, you won’t miss the bread.

It’s easier than you think to make this nutritious soup in your own kitchen. With carefully selected gluten free ingredients and several surefire tips, you simply can’t go wrong.

Ingredients

Base Ingredients:
– Onions: I use yellow onions sliced 1/4 inch thick.
– Butter and garlic for caramelizing the onions.
– Chicken broth, beef broth, and water for the soup base. If you prefer, you can use vegetable broth.
– White wine: I use Pinot Grigio or Sauvignon Blanc.

Thickening Agent:
– Bob’s Red Mill GF All Purpose Baking Flour

Flavor Enhancers:
– Worcestershire sauce: This adds a rich umami depth to the onion soup. Lea & Perrins is gluten free.
– Paprika: This contributes a warm, earthy, and slightly sweet flavor, along with a vibrant red color. It comes in varieties, including sweet, smoked, and hot, each with its unique flavor profile. I like the sweet in this recipe.

Toppings:
– Gluten free baguette: Slice diagonally, grill, and bake atop the soup. Today I have Udi’s; I have also used Schar baguettes.
– Swiss cheese, mozzarella, and Parmesan cheese for a broiled cheese crust: I recommend mozzarella and parmesan that you grate yourself. The pre-grated type contains preservatives meant to keep it from clumping. It doesn’t melt quite as well.

Instructions

*Free printable recipe card is available at the end of the post.

First melt butter in your saucepan. Cook your onions on low for about 30-40 minutes until they’re golden and caramelized for a real flavor boost.

Add your garlic towards the last minute so that it gets softened, but doesn’t burn. Stir occasionally.

Then stir in some flour. And add broth, water, Worcestershire sauce and wine. Increase the heat until the soup is boiling and then reduce to a simmer and cover for just about 15 minutes.

Meanwhile, slice your gluten free baguette diagonally because this will give you larger slices.

Add a tablespoon of butter to a skillet.

Grill the toast slices, pressing down on them with a spatula, about 1-2 minutes until golden. Flip over and grill the other sides.

Then divide your soup into oven proof soup bowls or crocks. Float one slice of toasted baguette bread in each bowl and top with swiss cheese, mozzarella cheese, parmesan, and a dash of paprika.

Arrange the bowls on a broiler-safe pan (I use my roasting pan) 6 inches from the heat source. Broil until the cheese becomes bubbly and achieves a delightful golden brown hue.

Since ovens vary, keep an eye on it, broil about, 4-5 minutes.

As it gradually melts, the cheese will cascade over the edges of the crock, creating a delightful, crispy seal.

And that’s it! Mouthwatering gluten free French onion soup for everyone to enjoy.

Pro tips and recipe notes
