How to Make Creamy Chicken and Spinach Casserole with Mozzarella and Parmesan Recipe
Step 1: Warm Up Your Oven
Start by preheating your oven to 350°F (175°C). A warm oven ensures your casserole bakes evenly, melting those glorious cheeses into a bubbly, golden masterpiece.
Step 2: Sauté the Garlic and Spinach
Heat olive oil in a large skillet over medium heat, then add the minced garlic. When it’s fragrant and golden, toss in the chopped spinach. Sauté just until it wilts, releasing its bright, earthy aroma. This step softens the spinach, melding its flavor seamlessly into the creamy base later on.
Step 3: Mix the Creamy Base
In a sizeable mixing bowl, whisk together the softened cream cheese, sour cream, mayonnaise, chicken broth, onion powder, dried basil, salt, and pepper. This luxurious mixture is the heart of our casserole, creating a silky, flavorful backdrop that ties everything together beautifully.
Step 4: Combine Chicken and Spinach
Fold the cooked chicken and sautéed spinach into the creamy mixture, stirring gently but thoroughly. This ensures every bite bursts with tender chicken pieces and vibrant spinach, all enveloped in rich creaminess.
Step 5: Assemble in Your Casserole Dish
Pour the combined mixture into a greased 9×13 inch casserole dish and level it out smoothly. The even spread helps the casserole cook uniformly and gives it a lovely presentation once baked.
Step 6: Top with Mozzarella and Parmesan
In a separate bowl, mix the shredded mozzarella and grated Parmesan cheeses. Sprinkle this irresistible blend evenly across the top of your casserole. These cheeses melt into a golden, bubbly layer that will make everyone’s mouth water.
Step 7: Add Breadcrumbs for Extra Crunch (Optional)
If you’re craving a bit of texture contrast, scatter breadcrumbs on top. When baked, they form a crisp, golden crust that makes each bite even more satisfying.
Step 8: Bake to Perfection
Place your casserole in the preheated oven and bake for 25 to 30 minutes. You’ll know it’s ready when the cheese is deliciously bubbly and has turned a gorgeous golden brown, signaling those fantastic flavors have melded perfectly.
Step 9: Let It Rest
Once out of the oven, give it a few minutes to rest. This little pause allows the casserole to set slightly, making it easier to serve while letting you savor that tempting aroma just a bit longer.
How to Serve Creamy Chicken and Spinach Casserole with Mozzarella and Parmesan Recipe

Garnishes
Sprinkle fresh chopped parsley or basil leaves on top for a pop of color and a hint of fresh herbaceousness. A light dusting of freshly cracked black pepper adds a bit of visual contrast and just the right amount of kick to enhance the cheesy richness.
Side Dishes
This casserole pairs beautifully with a crisp green salad dressed in a tangy vinaigrette to cut through the richness. Roasted vegetables or garlic bread also complement it well, providing additional layers of texture and flavor that round out a wholesome meal.
Creative Ways to Present
For a party, serve this casserole in individual ramekins for personalized portions that look elegant and inviting. Alternatively, scoop portions into bread bowls for a fun, rustic presentation that’s sure to impress guests and make the meal feel extra special.
Make Ahead and Storage
Storing Leftovers
Cool the casserole completely before transferring leftovers to an airtight container. Stored in the refrigerator, it will stay fresh and delicious for up to 3 days, making it perfect for quick reheats during busy weekdays.
Freezing
You can freeze the casserole before baking for up to 2 months. Just cover it tightly with foil or plastic wrap, then thaw overnight in the refrigerator before baking as directed. This convenience means a homemade meal is always within reach, no matter how hectic your schedule.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through and bubbly or use a microwave for a quicker option. To keep the topping crisp, consider reheating uncovered in the oven. Either way, it tastes just as comforting and creamy as when freshly made.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just be sure to thaw and squeeze out as much excess moisture as possible to prevent the casserole from becoming watery. Frozen spinach works well and saves prep time.
Is it necessary to use both mozzarella and Parmesan?
Using both cheeses creates a beautiful balance of creamy melt and sharp flavor, but feel free to adjust based on your preference. Cheddar or a blend of Italian cheeses can also work nicely.
Can I substitute the mayonnaise and sour cream?
You can, though they add creaminess and tang that enrich the casserole. Greek yogurt works well as a substitute for sour cream, and a light mayonnaise alternative can be used if preferred.
What can I use if I don’t have cream cheese?
Cream cheese is key for that silky texture, but you can replace it with ricotta or mascarpone for a slightly different creaminess and flavor profile.
How do I make this casserole gluten-free?
Simply skip the breadcrumbs or use gluten-free breadcrumbs for the topping. The rest of the recipe is naturally gluten-free, making it easy to adapt for dietary needs.
