Low Carb Keto French Onion Soup Recipe

In a Dutch oven, heat the butter and 2 tablespoons bone broth over medium heat. Add the onions. Caramelize onions according to the instructions here, about 30-40 minutes total, adding the additional 2 tablespoons bone broth after 20 minutes.

Push the onions to the sides of the pan and make a well in the center. Add the minced garlic and thyme leaves. Saute for about 1 minute, until fragrant.

Add the wine. Scrape the bottom of the pan with a wooden spoon to deglaze.

Add the remaining broth and bay leaves. Bring the soup to a boil, then reduce heat to a simmer. Cover and cook for 30 minutes.

Meanwhile, make the 90-second bread according to the instructions here. Using a rectangular baking dish, you’ll double the recipe to make 2 rectangular slices, then cut those in half to make 4 square slices total.

Preheat the oven to 400 degrees F (204 degrees C).

Arrange the bread in a single layer on a baking sheet. Toast in the oven for 3-5 minutes, until golden on the bottom.

Flip and toast for 3-5 more minutes, until golden on the other side.

Remove the bread from the oven. Set the oven to broil.

Ladle the soup into oven safe bowls and place them onto a baking sheet or baking dish. Top each bowl with a slice of bread, then sprinkle with shredded cheese. Place under the broiler for 2-4 minutes, until cheese is melted and browned.
