How to Make Creamy Chicken and Spinach Casserole
Step 1: Preheat and Prepare Your Baking Dish
Get your oven ready by preheating it to 375°F (190°C). Lightly grease a 9×13-inch baking dish so that your creamy casserole slides out easily with every scoop and cleanup is a breeze.
Step 2: Sauté the Aromatics and Spinach
Heat the olive oil in a large skillet over medium heat. Toss in the chopped onion, sautéing until it’s translucent and fragrant, which should take about three minutes. Stir in the minced garlic and cook for another minute. Add all the fresh spinach and stir until it’s just wilted and tender, soaking up all those savory flavors.
Step 3: Mix the Creamy Chicken and Spinach Casserole Filling
In a spacious bowl, combine your cooked shredded chicken, the sautéed spinach mixture, cream of chicken soup, tangy sour cream, melty mozzarella, savory Parmesan, chicken broth, and all the seasonings. Stir everything together until the mixture is smooth and every bite will be packed with flavor.
Step 4: Spread into the Baking Dish
Pour the creamy mixture into your prepared baking dish and smooth it out evenly. This helps the Casserole cook uniformly, ensuring every serving is loaded with all the good stuff.
Step 5: Add the Crunchy Topping
In a small bowl, mix the crushed Ritz crackers or breadcrumbs with the melted butter. Sprinkle this mixture evenly over the casserole for a golden, crunchy topping once baked.
Step 6: Bake to Perfection
Place the Creamy Chicken and Spinach Casserole in the oven, uncovered. Bake for 25 to 30 minutes, or until the casserole is bubbling at the edges and the topping has turned a delectable golden brown.
Step 7: Rest and Serve
Let the casserole rest for about five minutes after baking. This short pause makes it easier to slice and serve, and the flavors meld even more beautifully during this time.
How to Serve Creamy Chicken and Spinach Casserole

Garnishes
A handful of freshly chopped parsley or basil sprinkled over the top adds both freshness and a pop of color. For a little extra sharpness, try a dusting of grated Parmesan or even a drizzle of good olive oil before serving. This extra flourish makes Creamy Chicken and Spinach Casserole look as good as it tastes!
Side Dishes
This casserole is hearty on its own, but pairs flawlessly with a crisp green salad, simple roasted vegetables, or a pile of garlic bread for sopping up every bit of creamy sauce. Rice or orzo also work well if you want to stretch the meal a little further without overshadowing the main event.
Creative Ways to Present
Try individual ramekins for dinner parties — everyone gets their own bubbling portion, which always feels festive. Or spoon the Creamy Chicken and Spinach Casserole into hollowed-out bread bowls for a fun, edible serving idea. Even topping the casserole with a fried or poached egg can transform it into a crowd-pleasing brunch.
Make Ahead and Storage
Storing Leftovers
Store any leftover Creamy Chicken and Spinach Casserole in an airtight container in the refrigerator, where it will keep for up to three days. The flavors only deepen and mellow, so leftovers are a treat in lunches and quick dinners.
Freezing
If you want to freeze your casserole, simply let it cool completely before wrapping securely in foil and plastic wrap. It’ll hold beautifully in the freezer for up to two months. For best results, freeze before baking and add the topping just before you pop it in the oven.
Reheating
To reheat, thaw overnight in the refrigerator if frozen, then bake covered at 350°F (175°C) until hot and bubbly throughout. If reheating single portions, a few minutes in the microwave with a damp paper towel over the plate will revive that luscious, creamy texture.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just thaw and squeeze out as much liquid as possible before adding it to the pan, so you maintain that satisfying creamy consistency in your Creamy Chicken and Spinach Casserole.
What’s the best way to shred the chicken?
If you’re using rotisserie or cooked chicken breasts, two forks work great for easy, quick shredding. You can also pulse cooked chicken in a stand mixer for super-fast, even shreds!
Is there a way to lighten up the casserole?
Yes, swap the sour cream for Greek yogurt and use reduced-fat cheese if you like. The result is still wonderfully creamy but with a lighter feel, perfect for making Creamy Chicken and Spinach Casserole a little more everyday-friendly.
Can I add pasta or rice to the casserole?
Certainly! Fold in some cooked pasta or rice along with the chicken for an even heartier meal in one dish. Just make sure you don’t overfill your baking dish, and you may want to add an extra splash of chicken broth to keep everything luscious.
How can I make this gluten-free?
Choose a gluten-free cream of chicken soup and swap the Ritz crackers or breadcrumbs for a gluten-free alternative. Check all seasoning blends for hidden gluten, and you’ll have a lovely gluten-free Creamy Chicken and Spinach Casserole!
