French Onion Soup has always been a favorite of mine, and this Keto French Onion Soup delivers on the classic flavors. With a rich, perfectly seasoned broth, garlic, and onions, all topped off with Gruyere cheese, you have a hearty soup that is impossible not to love. Try it once, and you will be hooked.


– ¼ cup butter – 2 tablespoons avocado oil – 2 small yellow onions halved and sliced thin(reduce to 1 for strict keto) – 1 tablespoon fresh thyme or one teaspoon dried – 1 teaspoon minced garlic – ¼ cup cooking sherry – 4 cups beef broth – 2 tablespoons coconut aminos – Salt and pepper – ½ teaspoon xanthan gum – 1 ½ ounces shredded Gruyere cheese – Optional: keto bread cut into rounds

– Heat the butter and avocado oil in a large saucepan over medium-high heat.

– Add the onions and thyme and cook, stirring occasionally, for 10 minutes.

– Reduce heat to medium and cook for another 30 minutes, until the onions are a deep golden brown.

– Stir in the garlic and cook for 1 more minute. – Add the cooking sherry and cook for 2 minutes, scraping up any browned bits.

– Add the broth, coconut aminos, salt, pepper, and xanthan gum. Simmer over medium heat for at least 15 minutes. – Preheat a broiler to high and ladle soup into broiler-safe soup crocks. Sprinkle with cheese. Alternatively, you can toast bread, add it to the crocks and top with the cheese.

– Broil for 2 minutes, until the cheese is bubbly.
