Ingredients
2 lbs (approx. 4 large) Boneless, skinless chicken breasts (cut horizontally into thinner cutlets)
8 oz Cremini or white button mushrooms, sliced
4 cups Fresh baby spinach
4 cloves Garlic, minced
1 tbsp Olive oil
1/2 cup Cream cheese, softened
1/2 cup Heavy cream or sour cream
1 1/2 cups Shredded mozzarella cheese
1/2 cup Grated Parmesan cheese
1 tsp Italian seasoning
1/2 tsp Garlic powder
Salt and black pepper to taste
Step-by-Step Instructions
1. Prep Oven & Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray.
2. Season & Lay Chicken: Season both sides of the chicken cutlets generously with salt, pepper, garlic powder, and Italian seasoning. Arrange the chicken pieces in a single layer at the bottom of the prepared baking dish.
3. Sauté Veggies: Heat olive oil in a large skillet over medium-high heat. Add the sliced mushrooms and cook for 4–5 minutes until browned. Add minced garlic and baby spinach, stirring for 1–2 minutes until the spinach wilts. Remove from heat.
4. Mix Cream Base: In a medium bowl, stir together softened cream cheese and heavy cream until smooth. Mix in the sautéed mushroom and spinach mixture.
5. Layer & Top: Spread the creamy spinach and mushroom mixture evenly over the chicken cutlets. Top generously with shredded mozzarella and grated Parmesan cheese.
6. Bake: Bake uncovered for 25 to 30 minutes, until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is melted and golden brown on top. Let rest 5 minutes before serving!
Chef’s Tips
Use Thin Cutlets: Thinly sliced chicken breasts bake faster and stay juicy while ensuring the cheese on top gets perfectly browned without burning.
Drain Excess Liquid: If your sautéed spinach holds extra moisture, gently press it with a paper towel before mixing with cream cheese to keep the sauce rich and thick.
