Looking for a quick, creamy, and cheesy dinner that's both comforting and healthy? This Creamy Spinach Chicken Casserole combines tender chicken breasts, fresh spinach, and a luscious parmesan cream sauce that bakes into a golden, cheesy crust.
Preheat the Oven: Preheat your oven to 500°F. Lightly coat a 13x9-inch baking dish with cooking spray and set it aside.
Make the Creamy Sauce: In a bowl, mix together the mayonnaise, sour cream, parmesan cheese, black pepper, and garlic salt to make the creamy sauce.
Assemble the Casserole:
Spread the fresh spinach evenly on the bottom of the prepared baking dish.
Layer the uncooked chicken breasts on top of the spinach.
Spread the creamy sauce mixture evenly over the chicken breasts.
Add Cheese and Bake: Sprinkle the shredded Monterey Jack cheese on top. Place the baking dish on the bottom rack of the oven and bake for 20-25 minutes, or until the spinach wilts and the chicken is cooked through.
Notes:
Use a baking dish that can safely handle temperatures up to 500°F, like a heavy Dutch oven-style baking dish.
