Ingredient Notes
Chicken breasts: Use boneless, skinless chicken breasts.
Spinach: Use frozen chopped spinach. Thaw and drain it well.
Cream of chicken soup: Creates the creamy sauce base.
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Lightly grease a medium casserole dish or 9×13-inch baking dish.
Step 2: Layer the Spinach and Soup
Spread the drained spinach evenly across the bottom of the prepared dish. Spoon the cream of chicken soup over the top and spread it gently to cover the spinach.
Step 3: Add the Chicken
Arrange the chicken breasts over the spinach mixture in a single layer, pressing them down slightly so they settle into the sauce.
Step 4: Cover and Bake
Cover the dish with foil and bake for 30 minutes. Uncover and continue baking for 15 to 20 minutes more, until the chicken is cooked through and the top is bubbling and lightly golden.
Step 5: Rest and Serve
Let the casserole rest for 5 to 10 minutes before serving. Spoon the creamy spinach around each piece of chicken when plating.
