Ingredients You’ll Need
Gathering your ingredients for Creamy Chicken and Spinach Casserole is a breeze—and each item has a starring role in making this casserole so crave-worthy. These components work together to create a dish that’s creamy, cheesy, savory, and topped with a satisfying crunch.
- Cooked chicken breast: Shredded chicken forms the hearty base and soaks up all that delicious sauce.
- Fresh baby spinach: Brings a splash of color and a subtly earthy flavor; wilted just enough to meld beautifully with the creamy mixture.
- Cream of chicken soup: The backbone of the creamy sauce, adding both body and savory richness.
- Sour cream: Adds an irresistible tang and silkiness that ties the whole dish together.
- Shredded mozzarella cheese: Provides that classic, stretchy-cheesy finish everyone loves.
- Grated Parmesan cheese: Brings a touch of nuttiness and depth to balance the creamy flavors.
- Garlic powder: Enhances the casserole with subtle garlicky warmth without overpowering it.
- Onion powder: Delivers a gentle savoriness, rounding out all the flavors.
- Salt: Elevates and unifies every other ingredient—you can adjust to your taste preference.
- Black pepper: Just a hint gives the casserole a little kick and complexity.
- Crushed Ritz or buttery crackers: That golden, crunchy topping makes each bite extra special and fun.
- Unsalted butter: Melting into the crackers, it ensures a topping that’s both crisp and unbelievably flavorful.
How to Make Creamy Chicken and Spinach Casserole
Step 1: Prep Your Baking Dish and Oven
Start by preheating your oven to 350°F (175°C), which gives you the perfect golden finish. Lightly grease a 9×13-inch baking dish—this not only ensures a stress-free cleanup, but it also stops our magical casserole from sticking, letting every serving come out flawlessly.
Step 2: Mix the Filling
In a large bowl, combine your shredded chicken, fresh spinach, cream of chicken soup, sour cream, mozzarella, Parmesan, garlic powder, onion powder, salt, and pepper. Stir everything together until the mixture looks creamy and the spinach is evenly distributed. The aroma alone will have you ready to dig in!
Step 3: Assemble the Casserole
Pour the creamy chicken and spinach mixture into the prepared baking dish, making sure to spread it out evenly. Every corner of the pan should get plenty of chicken, spinach, and saucy goodness—this helps the casserole bake evenly and ensures no one fights over the “best bite.”
Step 4: Craft the Crunchy Topping
Grab a small bowl and mix your crushed Ritz crackers (or your favorite buttery crackers) with the melted butter until all those crumbs look beautifully coated. Evenly sprinkle this irresistible mixture over your casserole. The topping is a big part of what makes Creamy Chicken and Spinach Casserole so satisfying!
Step 5: Bake to Golden Perfection
Place the casserole uncovered in your preheated oven and bake for 25 to 30 minutes. You’ll know it’s ready when the sauce is bubbling along the edges and the cracker topping is deeply golden. Let the casserole stand for 5 minutes after baking—this helps it set up and makes serving much easier.
How to Serve Creamy Chicken and Spinach Casserole

Garnishes
Give your Creamy Chicken and Spinach Casserole a little fresh flair with a sprinkle of chopped parsley or basil on top. The burst of green brightens up the comfort-food palette, while a few grinds of black pepper over the top adds just the right touch of spice. If you love a little extra savoriness, thinly sliced green onions make a lovely finishing touch.
Side Dishes
This casserole shines with simple, wholesome sides. A crisp green salad tossed in a light vinaigrette is the perfect counterpoint to all that creamy, cheesy goodness. Steamed or roasted vegetables like broccoli, carrots, or green beans are fantastic for adding color and texture to your plate, and some warm, crusty bread is never a bad idea to help scoop up every last bit of sauce.
Creative Ways to Present
For dinner parties, try serving the Creamy Chicken and Spinach Casserole in individual ramekins for a charming, personalized touch. Or, spoon it into puff pastry shells for a fun, hand-held twist on the classic. You can even turn leftovers into lunch by tucking a scoop into a wrap or pita, with extra spinach and a dash of hot sauce on the side!
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftovers tightly with foil or transfer to an airtight container. They’ll keep well in the refrigerator for up to three days, making Creamy Chicken and Spinach Casserole a fantastic meal prep option for busy weeks.
Freezing
This casserole freezes beautifully! Let the baked casserole cool completely before wrapping it securely or placing portions in airtight containers. Store in the freezer for up to three months. For best texture, freeze before adding the cracker topping, and sprinkle it on just before reheating.
Reheating
To reheat, cover the casserole with foil and warm it in a 350°F (175°C) oven until hot and bubbly, about 20 minutes if reheating from the fridge (a bit longer if coming from the freezer). If the cracker topping seems to have softened, just uncover it for the final 5 minutes to re-crisp. Individual portions can be microwaved for a quick lunch, though the oven is best for restoring the topping’s crunch.
FAQs
Can I use rotisserie chicken in my Creamy Chicken and Spinach Casserole?
Absolutely! Rotisserie chicken is a huge time-saver and infuses the casserole with extra flavor. Just shred or chop the meat and use it exactly as you would regular cooked chicken breast.
Is there a substitute for cream of chicken soup?
If you’d prefer a homemade touch or need to avoid canned soup, try a simple homemade white sauce (béchamel) made with butter, flour, chicken broth, and milk. Season generously for the most flavorful result.
Can I make this casserole ahead of time?
Yes! You can assemble Creamy Chicken and Spinach Casserole up to a day in advance. Keep it covered in the fridge, then add the cracker topping and bake fresh when you’re ready. This makes it perfect for entertaining or those nights when you want to have dinner ready to pop right in the oven.
What if I don’t have fresh spinach?
No problem! Frozen chopped spinach works wonderfully here. Just make sure to thaw it completely and squeeze out as much excess liquid as possible so your casserole stays thick and creamy.
Can I make Creamy Chicken and Spinach Casserole gluten-free?
Absolutely! Use gluten-free crackers for the topping and make sure your soup and chicken broth are certified gluten-free. The other ingredients are naturally free of gluten, so it’s an easy swap.
