Simple Step-by-Step Instructions
1. Preheat & Prepare
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Prepare the Sauce
In a bowl, mix together the spinach, heavy cream, Parmesan, garlic, nutmeg, salt, and pepper until well combined.
3. Assemble the Dish
Arrange the chicken breasts in the baking dish. Pour the sauce evenly over the top, ensuring each piece is coated.
4. Bake
Cover with foil and bake for 25 minutes.
Remove the foil and continue baking for 10–15 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the sauce is bubbling.
Optional: Broil for 2–3 minutes to achieve a lightly golden top.
5. Rest & Serve
Allow the dish to rest for 5 minutes before serving. Spoon extra sauce over each portion for maximum flavor.
