Ingredients You’ll Need

For the Chicken Base:

4 boneless, skinless chicken breasts – about 1.5 lbs, pounded slightly for even cooking.
Salt & pepper – to season the chicken before baking.
1 tablespoon olive oil – for sautéing mushrooms and garlic.

For the Creamy Spinach Mushroom Mixture:

2 cups fresh spinach, chopped – you can substitute with frozen spinach (thawed and drained).
1 cup mushrooms, sliced – white button, cremini, or baby bella mushrooms all work well.
2 cloves garlic, minced – fresh garlic brings a stronger aroma, but garlic powder works too.
1 cup cream cheese, softened – the creamy base of the filling.
½ cup grated Parmesan cheese – adds a salty, nutty flavor.
1 teaspoon Italian seasoning – for that herby Mediterranean kick.

For the Topping:

½ cup shredded mozzarella cheese – for a gooey, melty golden topping.

Step-by-Step Instructions

Step 1: Prepare the Chicken

Preheat oven to 375°F (190°C).
Lightly grease a baking dish with olive oil or non-stick spray.
Pat the chicken breasts dry with a paper towel, then season both sides with salt and black pepper.

Step 2: Cook the Mushrooms and Garlic

In a large skillet, heat 1 tablespoon olive oil over medium heat.
Add the sliced mushrooms and sauté for 5–7 minutes, until golden brown and slightly caramelized.
Add minced garlic and cook for 1 more minute until fragrant. Remove from heat.

Step 3: Make the Creamy Mixture

In a mixing bowl, combine softened cream cheese, Parmesan cheese, Italian seasoning, salt, and pepper.
Stir in the chopped spinach and the sautéed mushrooms with garlic. Mix well until you have a creamy, chunky mixture.

Step 4: Assemble the Bake

Place chicken breasts in the prepared baking dish.
Spread the creamy spinach mushroom mixture evenly over each chicken breast.
Sprinkle shredded mozzarella cheese generously on top.

Step 5: Bake to Perfection

Bake uncovered for 25–30 minutes, or until chicken is fully cooked (internal temperature should reach 165°F / 74°C).
If you want extra golden cheese, broil for the last 2 minutes.

Step 6: Rest and Serve

Remove from oven and let rest for 5 minutes before serving.
Garnish with fresh parsley or extra Parmesan if desired.

Steamed rice or buttered pasta to soak up the sauce.
