Step 1

Preheat the oven to 375°F (190°C).

Step 2

In a large skillet, heat the olive oil over medium heat. Add the sliced mushrooms and sauté until they are golden brown, about 5-7 minutes.

Step 3

Add the chopped spinach to the skillet and cook until wilted, about 2-3 minutes. Season with garlic powder, onion powder, Italian seasoning, salt, and pepper. Remove from heat.

Step 4

In a baking dish, place the chicken breasts in a single layer. Pour the heavy cream over the chicken, ensuring it is evenly covered.

Step 5

Spread the sautéed spinach and mushroom mixture over the chicken.

Step 6

Sprinkle the shredded mozzarella cheese and grated Parmesan cheese on top.

Step 7

Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.

Step 8

Let it cool for a few minutes before serving.
