Ingredients

For the Chicken & Mushrooms

  • 1.5 lbs (680 g) chicken breasts, cut into cutlets or bite-sized pieces
  • 8 oz (225 g) cremini or button mushrooms, sliced
  • 1 tbsp olive oil
  • 1 tbsp butter
  • 1 tsp salt
  • ½ tsp black pepper

For the Creamy Garlic Sauce

  • 4 garlic cloves, minced
  • 1 cup chicken broth
  • 1 cup heavy cream
  • ½ cup grated Parmesan cheese
  • 1 tsp Italian seasoning
  • 2 cups fresh spinach, roughly chopped

Optional Topping

  • ½ cup shredded mozzarella cheese
  • 2 tbsp grated Parmesan cheese

Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.
  2. Season the chicken with salt and pepper.
  3. Heat olive oil and butter in a large skillet over medium-high heat.
  4. Cook the chicken for 4–5 minutes per side until lightly browned. Remove and set aside.
  5. In the same skillet, add mushrooms and sauté for 5 minutes until tender and golden.
  6. Stir in minced garlic and cook for 30 seconds until fragrant.
  7. Pour in chicken broth and simmer for 2 minutes, scraping any browned bits from the pan.
  8. Add heavy cream, Parmesan cheese, and Italian seasoning. Stir until smooth.
  9. Mix in spinach and cook for 1–2 minutes until wilted.
  10. Place the chicken in the prepared casserole dish and pour the mushroom-spinach sauce over the top.
  11. Sprinkle with mozzarella and additional Parmesan if desired.
  12. Bake for 20–25 minutes until bubbly and the chicken reaches an internal temperature of 165°F (74°C).
  13. Allow it to rest for 5 minutes before serving.

Notes

  • Fresh spinach can be replaced with frozen spinach; thaw and drain well before use.
  • Chicken thighs may be substituted for extra tenderness.
  • Add red pepper flakes for a mildly spicy kick.

Tips

  • Do not overcook the chicken during the skillet step since it will continue cooking in the oven.
  • Use freshly grated Parmesan for the smoothest sauce.
  • Let the casserole rest briefly before serving to allow the sauce to thicken.
  • Pair with rice, pasta, mashed potatoes, or crusty bread.
