What You’ll Need for This Chicken and Spinach Casserole
Here’s the scoop on the ingredients I always gather for my chicken and spinach casserole. I like to keep things straightforward but flavorful—great for busy nights when you want dinner on the table without fuss.

- 3 cups cooked chicken, shredded or diced (rotisserie chicken works wonders for quick meals)
- 4 cups fresh spinach, roughly chopped (fresh spinach really elevates this baked chicken spinach dish, but frozen works if you squeeze out the moisture)
- 1 cup shredded mozzarella cheese (for that gooey cheesy spinach chicken bake feel)
- 1 cup shredded cheddar cheese (sharp and melty for extra flavor)
- 1 small onion, finely chopped
- 2 cloves garlic, minced (aroma is key!)
- 1 cup sour cream (adds creaminess without heaviness)
- 1 cup cream cheese, softened (my secret weapon in creamy chicken casserole)
- 1/2 cup grated Parmesan cheese
- 1 teaspoon dried thyme or Italian seasoning
- 1/2 teaspoon salt and freshly cracked black pepper, to taste
- 1 tablespoon olive oil or butter, for sautéing
I always prefer fresh spinach when making this chicken and spinach casserole because it keeps that bright, fresh flavor. When buying spinach, you’ll find it easily in the produce section or even pre-washed in bags for those busy days—just make sure to give it a good rinse and pat dry.
Here’s a little trick I picked up: sauté the onions and garlic first in olive oil or butter to bring out their sweetness before adding the spinach. It cuts down the spinach’s moisture and prevents the casserole from turning watery—something I learned the hard way the first couple times.
For families on a budget, frozen spinach can be a lifesaver—just thaw and squeeze it dry to avoid sogginess. And, if you want to prep ahead, cooked shredded chicken can be kept in the fridge for 2-3 days or frozen in portions—so you can make this healthy chicken casserole anytime without fuss.

Let’s Make This Chicken and Spinach Casserole Together
Making this chicken and spinach casserole with you feels like sharing a warm kitchen moment, so let’s get cooking step-by-step! Don’t worry if you’re new to casseroles—all of this comes together quite smoothly, I promise.
- Preheat your oven to 375°F (190°C). While it warms up, spray a medium-sized casserole dish with a little non-stick spray or lightly butter it. This baked chicken spinach dish will cook evenly in a snug pan.
- Cook your veggies. Heat olive oil or butter in a large skillet over medium heat. Toss in chopped onions and sauté until soft and translucent (about 3-4 minutes), then add the garlic and cook for another minute. This fragrant base really makes the cheesy spinach chicken bake sing.
- Add the spinach. Toss in your chopped fresh spinach and cook until the leaves wilt and most moisture cooks off—this step is crucial. Stir frequently to avoid lumps. It usually takes about 5 minutes for that perfect wilt.
- Mix the creamy base. In a large bowl, blend sour cream, cream cheese, Parmesan cheese, thyme (or Italian seasoning), salt, and pepper until smooth and creamy. The mix should be thick but spreadable—this is your creamy chicken casserole magic.
- Combine chicken, veggies, and creamy mix. Stir in the cooked chicken and spinach mixture into the creamy base until well combined.
- Add cheeses and assemble. Fold in mozzarella and cheddar cheese gently—reserve a little mozzarella for topping. Pour everything into the casserole dish and spread evenly.
- Bake and relax! Pop the dish into the oven for about 25-30 minutes, or until the top is bubbly and golden. Your kitchen will start to smell incredible—almost like a hug in a pan!
- Let it rest before serving. Give it 5-10 minutes to settle after baking so it slices beautifully.
In my kitchen, this chicken and spinach casserole usually takes about 45 minutes total from start to finish, including prep. While it’s baking, I like to tidy up or set the table—those 30 minutes always go by fast!

Your Chicken and Spinach Casserole Questions Answered
Q: Can I use frozen spinach instead of fresh in this chicken and spinach casserole?
A: Absolutely! Just be sure to thaw it completely and squeeze out as much water as possible. I’ve learned the sogginess lesson over and over with this creamy chicken casserole. Frozen spinach can work perfectly if prepped right! This little fix helps keep your casserole from turning into a watery mess.
Q: What’s the best type of chicken to use?
A: I love using rotisserie chicken for quick meals, but leftover roasted or grilled chicken works just as well. Sometimes I bake breasts or thighs and shred them fresh. For a healthy chicken casserole, leaner breast meat is usually preferred, but thighs add more flavor.
Q: How do I store leftovers?
A: Store your chicken and spinach casserole in an airtight container in the fridge for up to 3-4 days. It reheats nicely in the oven at 350°F or in the microwave—just add a splash of milk if it feels a little dry.
Q: Can I make this spinach chicken bake ahead of time?
A: Yes! Prepare the casserole completely but hold off on baking. Cover and refrigerate for up to 24 hours, then bake as usual. This is a lifesaver on busy days.
Q: Can I swap out the cream cheese for something lighter?
A: Sure thing. Greek yogurt or sour cream can replace cream cheese, though it may be less thick and rich. For a lighter healthy chicken casserole version, I sometimes mix half cream cheese and half Greek yogurt.
Q: My family is picky about spinach—any suggestions?
A: Try finely chopping or even pureeing the spinach before mixing it in. The cheese and creamy sauce usually mask the flavor nicely. You can also boost flavor with mild herbs or a little garlic.
Q: How can I make this casserole extra cheesy?
A: Bonus cheese on top is always a winner. I recommend mixing in a little feta or gouda along with mozzarella and cheddar for a fun cheesy spinach chicken bake twist.
