- 1 small onion: finely chopped to bring subtle sweetness and depth.
- 2 cloves garlic: minced to infuse aromatic flavor that complements the chicken and spinach.

How to Make Creamy Chicken and Spinach Casserole Recipe
Step 1: Prepare the Oven and Sauté Aromatics
Begin by preheating your oven to 350°F (175°C) so it’s perfectly hot when your casserole is ready to bake. In a large skillet, heat olive oil over medium heat, then sauté the finely chopped onion and minced garlic until they become soft and fragrant—about 3 to 4 minutes. This step builds the foundation of flavor for the entire dish, so don’t rush it!
Step 2: Wilt the Spinach
Add the chopped fresh spinach to the skillet with the onions and garlic, cooking it until it wilts down, which should take about 2 to 3 minutes. The spinach will add a lovely green color and a touch of earthiness to the casserole. Once wilted, remove the skillet from heat and let the mixture cool slightly so it won’t make the creamy filling too hot or watery.
Step 3: Blend the Creamy Base
In a large mixing bowl, combine the sour cream, softened cream cheese, mayonnaise, dried Italian seasoning, salt, and pepper. Blend these until smooth and creamy. This mixture is the heart of your casserole, giving it that signature rich and velvety texture that everyone looks forward to.
Step 4: Combine All the Ingredients
Fold the cooked chicken, sautéed spinach mixture, shredded mozzarella, and half of the grated Parmesan cheese into the creamy base. Gently mix everything until it’s well incorporated—be sure to keep the cheese evenly distributed for maximum melt and flavor in every bite.
Step 5: Bake to Perfection
Transfer your creamy mixture into a greased baking dish and smooth the top. Sprinkle the remaining Parmesan cheese over the surface to create a deliciously crisp and golden topping. Bake uncovered for 25 to 30 minutes until the casserole is bubbly and the top turns a gorgeous golden brown. Let it rest for about 5 minutes before serving to set and cool slightly.

Garnishes
A sprinkle of freshly chopped parsley or basil adds a fresh and vibrant touch that brightens the dish visually and enhances the flavors. A light drizzle of extra virgin olive oil or a pinch of red pepper flakes can also add exciting layers if you want a little kick.
Side Dishes
This casserole pairs beautifully with simple sides like a fresh green salad dressed with lemon vinaigrette, or you can offer warm crusty bread to sop up the creamy sauce. Roasted vegetables or garlic mashed potatoes also complement the richness perfectly, making your meal balanced and satisfying.
Creative Ways to Present
For a fun twist, serve this casserole in individual ramekins for personal, elegant portions. You can also layer it with cooked pasta or rice for a different texture or serve it with tortilla chips on the side for a playful combo of creamy and crunchy.
Make Ahead and Storage
Storing Leftovers
Leftover Creamy Chicken and Spinach Casserole Recipe keeps well in an airtight container in the refrigerator for 3 to 4 days. This gives you ready-to-go deliciousness for quick lunches or dinners during the week.
Freezing
This casserole freezes beautifully, making it a perfect make-ahead meal. Just cover it tightly with foil or plastic wrap and freeze for up to 2 months. Thaw overnight in the fridge before reheating to preserve its creamy texture and flavors.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through, about 15-20 minutes, to keep that bubbly, golden top intact. Microwaving works in a pinch but may soften the texture slightly, so the oven is best for that fresh-baked experience.
FAQs
Can I use frozen spinach instead of fresh?
Yes! Just make sure to thaw and squeeze out excess moisture from the frozen spinach to avoid watering down your casserole. Fresh spinach is preferred for texture, but frozen works fine in a pinch.
What type of chicken works best for this recipe?
Cooked, shredded chicken works perfectly. You can use rotisserie chicken, baked, or boiled chicken breasts—whatever you have on hand is great, making this recipe super flexible.
Is this casserole gluten-free?
Yes, all the ingredients listed are naturally gluten-free, making this casserole safe for those with gluten sensitivities or celiac disease. Just double-check any packaged ingredients to be sure.
Can I add other vegetables to the casserole?
Absolutely! Diced mushrooms, chopped bell peppers, or even artichokes would be fantastic additions to boost flavor and nutrition. Just sauté them along with the onions and garlic before combining with the rest.
How can I make this dish lighter?
Try using reduced-fat cream cheese and sour cream and substituting part of the mayonnaise with Greek yogurt. Also, using less cheese or low-moisture mozzarella can help cut calories while still keeping things creamy.
