Ingredients

Scale

The key to this dish lies in selecting the right ingredients that will build layers of flavor without complicating the process. I always choose fresh, organic mushrooms and free-range chicken breasts when possible, as their quality shines through in a simple recipe like this. Fresh garlic is a must—pre-minced just won’t do when you want that fragrant punch. When I started cooking for my own kids, I realized how much the best ingredients can elevate even the easiest meals, making them feel special and loved.

  • 4 boneless, skinless chicken breasts
  • 2 cups sliced cremini or white mushrooms
  • 4 cloves garlic, minced
  • 1 cup heavy cream
  • 1/2 cup chicken broth (low sodium)
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • 2 tablespoons olive oil
  • 1 teaspoon dried thyme or 1 tablespoon fresh thyme leaves
  • Salt and black pepper, to taste
  • Fresh parsley, chopped (for garnish)

Substitutions: You can swap the heavy cream for full-fat coconut milk if you prefer a dairy-free option. If mozzarella isn’t your thing, cheddar or Monterey Jack work beautifully here. And if chicken breasts aren’t on hand, thighs are a juicier alternative that also fits keto perfectly.

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a baking dish with olive oil.
  2. Heat olive oil in a large skillet over medium heat. Season chicken breasts with salt, pepper, and thyme.
  3. Sear the chicken on both sides until golden brown, about 3-4 minutes per side. Transfer to the baking dish.
  4. In the same skillet, add mushrooms and sauté until they release their moisture and start to brown, about 6 minutes.
  5. Add minced garlic to the mushrooms and cook for another minute until fragrant, stirring frequently to avoid burning.
  6. Pour in the chicken broth and let it simmer for 2 minutes, scraping any browned bits off the bottom of the pan.
  7. Reduce heat to low and stir in the heavy cream. Let the sauce thicken slightly for 3-4 minutes.
  8. Pour the creamy mushroom sauce over the chicken breasts in the baking dish.
  9. Sprinkle mozzarella and Parmesan evenly on top.
  10. Bake uncovered for 20-25 minutes or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is bubbly and golden.
  11. Garnish with fresh parsley before serving for a pop of color and freshness.
