  5. 1 small onion, finely chopped

  6. 3 cloves garlic, minced

  7. 1 teaspoon dried thyme

  8. 1 teaspoon dried rosemary

  9. 1 cup chicken broth

  10. 1 cup heavy cream

  11. 1/2 cup grated Parmesan cheese

  12. 1 cup shredded mozzarella cheese

  13. Fresh parsley, chopped (for garnish)


Preheat Oven

  • Preheat your oven to 375°F (190°C).

Season Chicken

  • Season the chicken breasts with salt and pepper on both sides.

Sear Chicken

  • In a large oven-safe skillet, heat olive oil over medium-high heat.

  • Add the chicken breasts and sear for 3-4 minutes on each side, or until browned.

  • Remove chicken from the skillet and set aside.

Cook Mushrooms

  • In the same skillet, add sliced mushrooms and cook until they release their moisture and become golden brown.

  • Add chopped onions and garlic, and sauté until softened.

Add Herbs

  • Stir in dried thyme and rosemary, cooking for an additional minute until fragrant.

Deglaze the Pan

  • Pour in the chicken broth, scraping the bottom of the pan to deglaze and incorporate any flavorful bits.

  • Let it simmer for a few minutes.

Add Cream and Cheese

  • Pour in the heavy cream, Parmesan cheese, and half of the shredded mozzarella.

  • Stir until the cheese is melted and the sauce is smooth.

Return Chicken to Skillet

  • Return the seared chicken breasts to the skillet, spooning some of the mushroom and cheese mixture over them.


  • Sprinkle the remaining mozzarella cheese over the top.

  • Transfer the skillet to the preheated oven and bake for about 20-25 minutes or until the chicken is cooked through.

Garnish and Serve

  • Remove from the oven, garnish with chopped fresh parsley, and serve hot.

  • You can serve this casserole over cauliflower rice or steamed vegetables for a low-carb option.
