- ½ cup sour cream: Adds a subtle tang and extra creaminess to balance the richness.
- ½ cup mayonnaise: Boosts moisture and smoothness throughout the dish.
- 2 cloves garlic: Minced for a fragrant, savory punch that awakens the flavors.

- 1 tablespoon olive oil: For sautéing garlic and spinach, adding a mild fruity undertone.
- 10 oz fresh spinach: Chopped and sautéed to bring fresh green goodness and a tender bite.
- 1 cup shredded mozzarella cheese: Melts beautifully with a mild, creamy taste.
- ½ cup grated Parmesan cheese: Brings a nutty, salty sharpness that elevates every forkful.
- 1 teaspoon onion powder: Adds subtle depth without overpowering the other ingredients.

How to Make Creamy Chicken and Spinach Casserole with Mozzarella and Parmesan Recipe
Step 1: Preheat and Sauté
Start by preheating your oven to 350°F (175°C). While it warms up, heat olive oil in a skillet over medium heat and add the minced garlic. Sauté for about one minute until you can smell that heady aroma filling your kitchen. This small but mighty step sets the tone for the casserole’s depth of flavor.
Step 2: Wilt the Spinach
Add the chopped fresh spinach to the skillet and cook until wilted, which usually takes just a few minutes. The spinach will shrink considerably but delivers vibrant color and fresh earthiness in every creamy bite. Once wilted, remove it from heat and allow it to cool slightly so it doesn’t curdle the creamy cheese mixture later.
Step 3: Whip Up the Creamy Base
In a large mixing bowl, combine the softened cream cheese, sour cream, mayonnaise, and chicken broth with onion powder, dried basil, salt, and pepper. Whisk everything together until smooth and silky—this is the heart of the creaminess that will hold your casserole together and keep each forkful wonderfully moist.
Step 4: Fold in Chicken and Spinach
Gently stir the cooked chicken and sautéed spinach into the cream mixture, making sure each piece is coated with that luscious sauce. This step is where the flavors start to get cozy with one another, promising a cohesive dish with bursts of chicken and tender greens throughout.
Step 5: Assemble the Casserole
Pour the creamy chicken and spinach mixture into a greased 9×13 inch casserole dish. Spread it out evenly to ensure every bite gets a perfect balance of ingredients. Then, in a separate bowl, combine the shredded mozzarella with the grated Parmesan and sprinkle this cheese blend generously over the top of the casserole.
Step 6: Optional Crunchy Topping and Baking
If you love a slightly crunchy top, sprinkle breadcrumbs over the cheese layer for an irresistible golden crust. Bake the casserole in the preheated oven for 25 to 30 minutes, or until you see the cheese bubbling and turning a gorgeous golden brown. This visual cue lets you know that all the flavors have beautifully melded together.
Step 7: Rest and Serve
Once baked, allow the casserole to rest for a few minutes before diving in. This resting time helps the casserole set so you can serve neat, flavorful portions with ease. It’s the perfect moment to grab your favorite plates and get ready for pure comfort food bliss.
How to Serve Creamy Chicken and Spinach Casserole with Mozzarella and Parmesan Recipe

Garnishes
Sprinkle some fresh chopped parsley or a few basil leaves on top just before serving to add a fresh burst of color that contrasts beautifully with the golden cheese topping. A little cracked black pepper over the top also adds a final layer of inviting aroma and flavor.
Side Dishes
This casserole pairs wonderfully with simple, refreshing sides such as a crisp green salad tossed with lemon vinaigrette, roasted vegetables like asparagus or Brussels sprouts, or even some crusty garlic bread to soak up every last drop of the creamy goodness.
Creative Ways to Present
Serve the casserole straight from the dish for cozy family dinners, or use individual ramekins for a refined and personalized touch at dinner parties. You can also scoop generous portions over a bed of fluffy rice or quinoa to add another comforting dimension.
Make Ahead and Storage
Storing Leftovers
Place any leftover casserole in an airtight container and store it in the refrigerator for up to 3 days. The flavors actually deepen overnight, making for an even tastier meal when reheated.
Freezing
This Creamy Chicken and Spinach Casserole with Mozzarella and Parmesan Recipe freezes beautifully. Transfer cooled portions into freezer-safe containers or wrap the entire casserole dish tightly with foil and plastic wrap. Freeze for up to 2 months. Just thaw in the fridge overnight before reheating.
Reheating
Reheat individual servings in the microwave for 2–3 minutes, or warm the whole casserole in an oven preheated to 350°F (175°C) until heated through, usually about 20 minutes. Cover with foil if reheating a whole dish to prevent the top from browning too much.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just be sure to thaw and squeeze out as much moisture as possible from the frozen spinach before adding it to avoid a watery casserole.
What type of chicken works best in this casserole?
Leftover cooked chicken breast or rotisserie chicken works brilliantly. You want it shredded or cubed so it mixes well with the creamy sauce.
Is this casserole freezer-friendly after baking?
It’s best to freeze the casserole before baking for optimal texture. However, you can freeze leftovers if stored properly, but reheated casserole texture might be slightly softer.
Can I substitute the cream cheese?
You could try using ricotta for a lighter texture, but the iconic creaminess of this recipe depends heavily on cream cheese, so changes might alter the rich consistency.
What can I add if I want it spicier?
Adding a pinch of red pepper flakes or mixing in some chopped jalapeños with the spinach will give the casserole a nice kick without overshadowing its creamy goodness.
