Step-by-Step Directions

Pat chicken breasts dry and season both sides with:
- Salt

Step 3: Optional Sear (Recommended)

- Parmesan cheese
- Half of the mozzarella cheese
Stir until smooth and creamy.
Step 6: Assemble the Dish
Place chicken breasts in the baking dish.
Top with sautéed spinach and mushroom mixture.
Pour the cream sauce evenly over everything.
Step 7: Add Cheese
Sprinkle remaining mozzarella cheese on top.
Step 8: Bake
Bake for 25–30 minutes, or until:
- Chicken reaches 165°F (74°C)
- Cheese is melted and bubbly
- Sauce is lightly golden
Step 9: Rest and Serve
Let the dish rest for 5 minutes before serving so the sauce thickens slightly.
