How to Make Creamy Chicken and Spinach Casserole Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). This simple step ensures your casserole will bake evenly as soon as it goes in.
Step 2: Sauté Garlic and Spinach
Heat olive oil in a skillet over medium heat. Add the minced garlic and sauté for about one minute until fragrant—this step unlocks its wonderful aroma. Then toss in the chopped spinach and cook for 2 to 3 minutes until wilted. This softens the greens, making every bite tender and flavorful.
Step 3: Mix the Creamy Base
In a large bowl, blend the softened cream cheese with sour cream, shredded mozzarella, grated Parmesan, salt, and pepper. Stir until the mixture is smooth and creamy—this mixture will coat the chicken and spinach beautifully, creating that signature luscious texture.
Step 4: Combine Chicken and Spinach
Fold the shredded chicken and cooked spinach into the creamy mixture. This step ensures every morsel of chicken is enveloped in cheesiness balanced by fresh greens, making the casserole irresistibly hearty and satisfying.
Step 5: Bake to Perfection
Spread the chicken and spinach mixture evenly into a greased 8×8 or 9×9-inch baking dish. Pop it in the oven and bake for 20 to 25 minutes until the top is hot and bubbly. The comforting aroma will fill your kitchen and build up delicious anticipation!
