- 2.5 lb Yellow onions (sliced thinly)
- 2 tbsp Butter
- 5 1/2 cups Beef bone broth
- 4 cloves Garlic (minced)
- 1 tbsp Fresh thyme
- 1/4 cup Dry white wine
- 2 medium Bay leaves
- 6 slices Keto 90-second Bread (triple the recipe)
- 6 oz Gruyere cheese (shredded)
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.
