How to Make Chicken and Spinach Casserole with Cream Cheese
Step 1: Prep Your Baking Dish and Oven
Start by preheating your oven to 375°F (190°C). Grease a 9×9-inch or similar-sized baking dish with a little olive oil or nonstick spray. This simple step ensures your Chicken and Spinach Casserole with Cream Cheese won’t stick and will be easy to serve.
Step 2: Sauté Garlic and Spinach
In a large skillet over medium heat, warm the olive oil. Add the minced garlic and sauté for just 30 seconds until it smells amazing—don’t let it brown! Stir in the chopped spinach and cook for 2 to 3 minutes until it wilts down and looks beautifully vibrant. Remove the skillet from the heat so the spinach doesn’t overcook.
Step 3: Mix Up the Creamy Base
Grab a large mixing bowl and combine the softened cream cheese, sour cream, mayonnaise, onion powder, salt, pepper, and paprika. Mix until the sauce is smooth and creamy. This dreamy mixture is what makes Chicken and Spinach Casserole with Cream Cheese so unforgettable.
Step 4: Combine the Chicken and Spinach
Gently fold the cooked chicken and the sautéed spinach into your creamy base. Stir until everything is evenly coated and you can see flecks of green spinach and juicy chicken throughout the mixture.
Step 5: Assemble and Bake
Transfer the mixture to your prepared baking dish and smooth the top with a spatula. Sprinkle mozzarella and Parmesan cheese evenly over the surface. Pop the casserole into the oven and bake for 20 to 25 minutes, or until the cheese is melted, bubbly, and golden around the edges.
Step 6: Rest and Serve
Let the casserole rest for about 5 minutes once it comes out of the oven. This gives the creamy filling a chance to set, making it easier to scoop and serve every delicious portion of Chicken and Spinach Casserole with Cream Cheese.
