How to Make Creamy Chicken and Spinach Casserole Recipe
Step 1: Prepare the Ingredients
Start by cooking and shredding your chicken if it isn’t already pre-cooked—this ensures the casserole has tender, bite-sized pieces throughout. If you’re using fresh spinach, giving it a quick sauté until it wilts lightly makes a huge difference in flavor and texture. For frozen spinach, thaw it fully and squeeze out any excess water to avoid a watery casserole.
Step 2: Make the Sauce
In a mixing bowl, combine the softened cream cheese, sour cream, minced garlic, finely chopped onion, salt, pepper, and the optional nutmeg. Stir everything together until you get a smooth, creamy, and well-blended mixture that will coat the chicken and spinach perfectly.
Step 3: Assemble the Casserole
Preheat your oven to 375°F (190°C). In a greased casserole dish, spread a layer of the shredded chicken, then add the sautéed or thawed spinach. Pour the creamy sauce over the top and mix gently to make sure the ingredients are evenly coated and combined.
Step 4: Add Cheese and Bake
Sprinkle the shredded mozzarella and grated Parmesan cheese evenly on top. Slide the dish into the oven and bake uncovered for 25 to 30 minutes. The cheese will melt, bubble, and turn a gorgeous golden brown, signaling that your casserole is ready.
Step 5: Serve and Enjoy
Allow the casserole to cool for a few minutes before serving. This resting time lets everything set up a bit, making each spoonful rich and creamy without losing its form. It’s comforting, indulgent, and absolutely irresistible.
How to Serve Creamy Chicken and Spinach Casserole Recipe

Garnishes
Adding fresh herbs like chopped parsley or basil can brighten up the look and taste of this casserole. A sprinkle of red pepper flakes or a drizzle of olive oil also makes the presentation pop and adds an inviting aroma.
Side Dishes
This casserole pairs beautifully with crisp green salads, roasted vegetables, or crusty bread to mop up every last bit of the creamy sauce. For a heartier meal, cooked rice or garlic mashed potatoes are fantastic accompaniments that complement the richness perfectly.
Creative Ways to Present
Try serving individual portions in ramekins for a charming presentation when entertaining guests. Alternatively, layer the casserole over a bed of cooked pasta before baking for a pasta bake twist. Adding sautéed mushrooms or artichoke hearts can give extra texture and flavor that impresses every time.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers into an airtight container and store in the refrigerator for up to 3 days. The flavors meld beautifully overnight, making it even tastier the next day!
Freezing
This Creamy Chicken and Spinach Casserole Recipe freezes wonderfully. Wrap it tightly with plastic wrap and aluminum foil or use a freezer-safe container. It keeps well for up to 2 months, so you can enjoy this comforting dish anytime you like.
Reheating
To reheat, thaw the casserole overnight if frozen, then warm it in a preheated oven at 350°F (175°C) for about 15–20 minutes or until heated through. You can also microwave individual portions, but the oven method best preserves the texture and melty cheese topping.
FAQs
Can I use rotisserie chicken for this recipe?
Absolutely! Rotisserie chicken is a fantastic shortcut that saves time and adds extra flavor to your casserole. Just shred it and you’re ready to go.
Is it possible to make this dish vegetarian?
Yes! Simply omit the chicken and add extra vegetables like mushrooms, artichokes, or cooked pasta to keep the casserole hearty and satisfying.
Can I substitute the cream cheese with Greek yogurt?
While Greek yogurt can add tanginess, it won’t create quite the same creamy texture. If you try it, use full-fat Greek yogurt and mix it carefully to avoid curdling during baking.
How do I prevent the casserole from becoming watery?
Make sure to sauté fresh spinach until excess moisture evaporates or squeeze out as much liquid as possible from thawed frozen spinach. This step is crucial to keep your casserole rich and creamy without sogginess.
Can I prepare this casserole in advance and bake later?
Yes, you can assemble the casserole and refrigerate it for up to 24 hours before baking. Just add a few extra minutes to the baking time if it’s chilled before going into the oven.
