Ingredients

  • 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

Instructions

  • 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.
