Learn how to make delicious Keto Garlic Mushroom Chicken Casserole. Easy recipe with step-by-step instructions.

  • Total Time: 45 minutes
  • Yield: 4 servings 1x

Ingredients

Scale

  • 4 boneless, skinless chicken breasts (about 1.5 lbs)
  • 2 cups cremini or white mushrooms, sliced
  • 4 cloves garlic, minced
  • 1 cup heavy cream
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • 1/4 cup chopped fresh parsley
  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • 1 teaspoon dried thyme
  • Salt and freshly ground black pepper, to taste
  • Optional substitution: For dairy-free, use coconut cream instead of heavy cream, and nutritional yeast in place of cheeses.
  • Optional substitution: Use turkey breasts or thighs if preferred.

Instructions

  1. Preheat your oven to 375°F (190°C). This is the perfect temperature to slowly bake the chicken, allowing it to remain juicy and tender.
  2. Season the chicken breasts generously with salt, pepper, and dried thyme. I always remind myself of Mama Lou’s advice here: “Don’t be shy with your seasoning—it’s the soul of the dish.”
  3. Heat the olive oil and butter together in a large skillet over medium heat. Once shimmering, add the chicken breasts and sear them for about 3-4 minutes on each side, until golden brown but not fully cooked through. Remove from the skillet and set aside.
  4. In the same skillet, add the sliced mushrooms and sauté for 5-7 minutes until they release their juices and start to brown. This step fills the kitchen with such a cozy aroma—I remember Ouma and I stealing tastes from the pan while waiting for the mushrooms to caramelize.
  5. Add the minced garlic to the mushrooms and cook for another minute until fragrant. Be careful not to burn the garlic—it should smell sweet and inviting.
  6. Pour in the heavy cream and stir well, scraping any browned bits from the bottom of the pan. Allow the cream to simmer gently for 3-4 minutes until it thickens slightly.
  7. Remove the skillet from heat and stir in the Parmesan cheese and half of the mozzarella cheese. This creamy mixture will coat the chicken beautifully and bring everything together.
  8. Place the seared chicken breasts in a casserole dish and pour the mushroom and garlic cream sauce evenly over them.
  9. Sprinkle the remaining mozzarella cheese on top, then cover the dish with foil.
  10. Bake for 20 minutes covered, then remove the foil and bake for an additional 10 minutes until the cheese is bubbly and golden.
  11. Remove from the oven and let it rest for 5 minutes before serving. Sprinkle with fresh parsley for a burst of color and freshness.
