Step‑by‑Step Instructions for Creamy Chicken and Spinach Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). As the oven warms, lightly grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking. This preparation step will ensure that the casserole bakes evenly and comes out perfectly golden.
Step 2: Prepare the Chicken
Cut 1.25 lb of chicken into 1-inch cubes, ensuring they are all roughly the same size for even cooking. Place the chicken pieces in a bowl and set them aside while you focus on the creamy sauce and other ingredients. This can be done in a matter of minutes, making the process efficient and enjoyable.
Step 3: Grate the Cheese
Next, grab your cheese grater and shred 8 oz of Monterey Jack cheese and a generous amount of Parmesan cheese. Set the grated cheeses aside in separate bowls, as you’ll need them later for the topping. The freshness of the cheese will enhance the flavor of your Creamy Chicken and Spinach Casserole significantly.
Step 4: Make the Creamy Sauce
In a medium mixing bowl, whisk together 1 cup of mayonnaise, 1/2 cup sour cream, 1 teaspoon garlic salt, 1 teaspoon onion powder, and 1/2 teaspoon pepper. Mix until the ingredients are fully combined and smooth, creating a rich and velvety sauce that will generously coat the chicken and spinach, adding layers of flavor to your dish.
Step 5: Layer the Spinach
Evenly spread 8 oz of spinach across the bottom of your greased baking dish. If using frozen spinach, ensure it is well-drained and squeezed of excess water to prevent a watery casserole. This layer of fresh or thawed spinach adds nutritious value and vibrant color, providing a beautiful base for the chicken.
Step 6: Add the Chicken
Now, distribute the cubed chicken over the layer of spinach. Make sure to scatter the chicken pieces evenly to ensure that every bite of your Creamy Chicken and Spinach Casserole is filled with tender chicken goodness. This step takes just a moment but is essential for a balanced dish.
Step 7: Pour the Creamy Sauce
Pour the creamy sauce over the chicken, ensuring each piece is coated evenly. Use a spatula to gently spread the sauce, covering both the chicken and spinach fully. This step creates a luscious, creamy layer that will melt beautifully during baking, enveloping everything in rich flavor.
Step 8: Add the Cheese Topping
Sprinkle the grated Monterey Jack and Parmesan cheese generously over the top of the casserole. The cheese not only adds extra flavor but will also form a bubbly, golden crust as it bakes. Take a moment to create an even layer so that every portion features that irresistible cheesy goodness.
Step 9: Bake the Casserole
Carefully place your baking dish in the preheated oven and bake for 30-35 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is bubbly and golden brown on top. Keep an eye on it towards the end to avoid over-browning, ensuring a perfectly cooked casserole.
Step 10: Let It Rest
Once out of the oven, let the Creamy Chicken and Spinach Casserole rest for 5-10 minutes before serving. This resting period allows the sauce to thicken slightly, making it easier to portion and enhancing the overall flavor. It’s a perfect time to set the table and prepare your favorite sides.

What if my casserole is too watery?
Oh no! A watery casserole can happen if the spinach wasn’t drained properly. To fix this, ensure your spinach is well-drained, and consider using a slotted spoon when serving.
