  • Total Time: 35 minutes
  • Yield: 4 servings

Ingredients

  • 1.5 lbs boneless, skinless chicken breasts
  • 1/2 teaspoon sea salt (or to taste)
  • 1/4 teaspoon ground black pepper (or to taste)
  • 1/4 cup gluten-free flour + 1 tablespoon for the sauce
  • 2 tablespoons clarified butter or ghee, divided
  • 1 lb mixed mushrooms (champignon, shimeji, or your favorites), sliced if needed
  • 4 fresh garlic cloves, minced
  • 1½ cups low-sodium chicken bone broth or stock
  • 1/3 cup freshly shredded mozzarella cheese
  • Fresh curly parsley, chopped (for garnish)
  • Avocado oil (for greasing the baking dish)

Instructions

  1. Preheat oven to 375°F. Lightly grease a 9×13-inch baking dish with avocado oil.
  2. If chicken breasts are thick, slice them in half lengthwise to ensure even cooking.
  3. Season both sides of chicken with salt and pepper. Lightly dredge in gluten-free flour.
  4. Heat 1 tablespoon of ghee in a large skillet over medium heat. Sear half of the chicken for 2 minutes per side, or until golden. Repeat with the remaining ghee and chicken.
  5. Transfer browned chicken to the prepared baking dish.
  6. In the same skillet, sauté mushrooms for 3–4 minutes. Add garlic and cook 1 minute more.
  7. In a bowl, whisk 1 tablespoon flour into the chicken broth until smooth. Pour into skillet, stirring to deglaze. Bring to a simmer.
  8. Pour mushroom sauce over the chicken in the baking dish. Sprinkle with mozzarella.
  9. Bake for 15–17 minutes, until chicken is cooked through and cheese is melted.
  10. Garnish with fresh parsley and serve hot.

Notes

  • Use a mix of mushrooms for a deeper, earthy flavor profile.
  • If you prefer a cheesier dish, add extra mozzarella or Parmesan before baking.
  • This dish pairs beautifully with mashed potatoes, rice, or roasted vegetables.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven.
