Ingredients
For the Chicken
- 6 boneless, skinless chicken breasts (about 2 pounds)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- 1 tablespoon olive oil
For the Vegetable Layer
- 8 ounces mushrooms, sliced
- 4 cups fresh spinach
- 2 cloves garlic, minced
- 1 tablespoon butter
For the Creamy Sauce
- 1 cup heavy cream
- 4 ounces cream cheese, softened
- ½ cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- ½ teaspoon onion powder
- ¼ teaspoon red pepper flakes (optional)
For Topping
- ½ cup shredded mozzarella cheese
- 2 tablespoons chopped fresh parsley
Equipment Needed
- 9×13-inch baking dish
- Large skillet
- Mixing bowl
- Measuring cups and spoons
- Wooden spoon
- Aluminum foil
Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of olive oil. Set aside.
Step 2: Season the Chicken
Pat the chicken breasts dry using paper towels. This helps the seasoning stick better and promotes even cooking.
Season both sides of the chicken with salt, black pepper, garlic powder, and paprika.
Heat olive oil in a large skillet over medium-high heat. Sear the chicken breasts for 2 to 3 minutes per side until lightly golden. The chicken does not need to be fully cooked at this stage because it will finish cooking in the oven.
Transfer the chicken to the prepared baking dish.
Step 3: Cook the Mushrooms and Spinach
Using the same skillet, melt the butter over medium heat.
Add the sliced mushrooms and sauté for 5 minutes, stirring occasionally, until they begin to soften and release moisture.
Add the minced garlic and cook for 30 seconds until fragrant.
Stir in the fresh spinach and cook for 1 to 2 minutes until wilted.
Remove the skillet from the heat.
Step 4: Make the Creamy Sauce
In a mixing bowl, combine:
- Heavy cream
- Cream cheese
- Parmesan cheese
- Mozzarella cheese
- Onion powder
- Red pepper flakes (if using)
Whisk until smooth and creamy.
Add the cooked mushroom and spinach mixture to the sauce and stir well.
Step 5: Assemble the Dish
Spread the creamy spinach and mushroom mixture evenly over the chicken breasts in the baking dish.
Make sure the chicken is fully covered with the sauce to help keep it moist during baking.
Sprinkle the remaining mozzarella cheese evenly over the top.
Step 6: Bake
Cover the baking dish loosely with aluminum foil.
Bake for 25 minutes.
Remove the foil and continue baking for an additional 10 minutes, or until the cheese is melted, bubbly, and lightly golden.
The chicken should reach an internal temperature of 165°F (74°C).
Step 7: Rest and Serve
Remove the baking dish from the oven and allow it to rest for 5 minutes.
Garnish with freshly chopped parsley before serving.
Serve hot and enjoy.
Chef’s Tips
Choose Fresh Spinach
Fresh spinach provides the best texture and flavor. If using frozen spinach, thaw completely and squeeze out excess moisture before adding it to the recipe.
Don’t Overcook the Chicken
Searing the chicken first helps lock in juices. Since it continues cooking in the oven, avoid fully cooking it during the searing stage.
Add More Flavor
For additional richness, try adding:
- Crispy bacon pieces
- Sun-dried tomatoes
- Fresh thyme
- Italian seasoning
Make It Extra Cheesy
If you love cheese, add a mixture of mozzarella and cheddar on top before baking for an even richer finish.
