- 1/2 cup mayonnaise: Helps bind ingredients and adds a subtle depth of flavor.
- 1 cup shredded mozzarella cheese: Melts beautifully for that gooey, cheesy goodness.
- 1/2 cup grated Parmesan cheese: Sprinkled both inside and on top for a sharp, nutty finish.
- 1 small onion, finely chopped: Sautéed to add sweet and savory undertones.
- 2 cloves garlic, minced: Infuses the dish with aromatic warmth.

How to Make Creamy Chicken and Spinach Casserole Recipe
Step 1: Prepare the base ingredients
Start by preheating your oven to 350°F (175°C). This ensures your casserole will bake evenly and develop that gorgeous golden top. Next, heat olive oil in a large skillet over medium heat, then sauté the chopped onion and minced garlic until they are tender and fragrant. This step builds a flavorful foundation that elevates the entire dish.
Step 2: Wilt the spinach
To keep the spinach vibrant yet tender, toss it into the skillet with the onions and garlic, cooking just until wilted. This will soften the leaves without turning them mushy, preserving both color and texture. Remove the skillet from heat and allow the mixture to cool slightly so it blends smoothly with the other ingredients.
Step 3: Combine the creamy mixture
In a large mixing bowl, blend sour cream, cream cheese, mayonnaise, Italian seasoning, salt, and pepper until silky and uniform. This creamy base is what makes this recipe so special—rich, tangy, and full of flavor that hugs every bite.
Step 4: Incorporate chicken, spinach, and cheese
Gently fold in the cooked chicken, sautéed spinach mixture, mozzarella, and half of the Parmesan cheese. This step ensures every spoonful bursts with melty cheese and savory chicken, perfectly kissed by the tender greens.
Step 5: Bake to perfection
Transfer everything into a greased baking dish and smooth the top for an even bake. Sprinkle the remaining Parmesan cheese on the surface—it creates a beautiful golden crust that adds texture contrast. Bake uncovered for 25 to 30 minutes until bubbly and golden. Let the casserole rest for about 5 minutes after baking; this helps it set nicely for easier serving.
How to Serve Creamy Chicken and Spinach Casserole Recipe
Garnishes
Simple garnishes like freshly chopped parsley or a sprinkle of crushed red pepper flakes can add a fresh pop of color and a little zing to this creamy casserole. A light drizzle of extra virgin olive oil or a few lemon zest curls work wonders to brighten the rich flavors.
Side Dishes
Pair this casserole with some crisp garden salad or roasted vegetables to add a crisp bite and balance the creaminess. Garlic bread or warm dinner rolls also complement this dish perfectly, soaking up the luscious sauce and making each meal feel like a celebration.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins for single portions, or layer it over a bed of fluffy rice or pasta for an extra indulgent plate. Adding a sprinkle of toasted breadcrumbs on top before baking gives a delightfully crunchy texture contrast worth trying.
Make Ahead and Storage
Storing Leftovers
This casserole keeps wonderfully in the fridge for up to 3 days. Store leftovers in an airtight container to maintain freshness and moisture. When you reheat, the flavors will be even more melded and comforting.
Freezing
You can freeze the casserole before or after baking. Wrap it tightly with plastic wrap and aluminum foil to prevent freezer burn. Frozen casserole stays good for up to 2 months. When ready to enjoy, thaw overnight in the fridge for best results.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through and bubbly again—usually about 20 minutes. If short on time, microwave portions in short intervals, stirring occasionally, but the oven method preserves the texture and flavor best.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just be sure to thaw and squeeze out any excess moisture from the frozen spinach before sautéing, so the casserole doesn’t turn watery.
Is it possible to make this casserole dairy-free?
Yes, by substituting dairy ingredients with plant-based alternatives like vegan cream cheese, sour cream, and cheese substitutes, you can still achieve a creamy texture with a slightly different flavor profile.
What kind of chicken works best for this recipe?
Leftover roasted or poached chicken works beautifully, or you can cook and shred chicken breasts or thighs fresh. Using pre-cooked chicken saves prep time without compromising taste.
Can I add other vegetables to this casserole?
Definitely! Mushrooms, bell peppers, or artichoke hearts make great additions. Just sauté them along with the onions and garlic to meld their flavors well.
How can I make this recipe spicier?
Incorporate a pinch of red chili flakes or a dash of hot sauce into the creamy mixture. For a smoky kick, smoked paprika also pairs surprisingly well with the cheesy chicken and spinach.
