Ingredients You’ll Need

These ingredients are straightforward but each plays a vital role in building the rich flavors and inviting textures of the casserole. From the creamy base to the fresh greens and perfectly seasoned chicken, every component matters.

• 2-3 cups cooked and shredded chicken: Use breasts or thighs for tender, juicy pieces that absorb all the creamy goodness.
• 4 cups fresh spinach or 1 package frozen spinach: Fresh adds a lovely pop of color, while frozen is convenient and just as tasty once drained well.
• 8 ounces cream cheese (softened): Creates the rich, velvety sauce that makes this casserole so irresistible.
• 1/2 cup sour cream: Adds tanginess and extra creaminess to the dish.
• 1 cup shredded mozzarella cheese: Provides a melty, gooey topping that pulls apart delightfully.
• 1/4 cup grated Parmesan cheese: Offers a sharp, nutty flavor that perfectly balances the richness.
• 2 cloves garlic (minced): Gives a fragrant punch that brightens the creamy base.
• 1 small onion (finely chopped): Adds sweetness and depth when combined with the garlic.
• 1/2 teaspoon salt: Enhances all the flavors without overpowering them.
• 1/4 teaspoon black pepper: Just enough spice to keep things interesting.
• Pinch of nutmeg (optional): A subtle warm note that makes the sauce extra special.
• Sliced mushrooms, artichoke hearts, or cooked pasta: Optional additions to customize your casserole and boost texture or heartiness.

How to Make Creamy Chicken and Spinach Casserole

Step 1: Prepare the Ingredients

Start by ensuring your chicken is cooked through and shredded into bite-sized pieces—breasts or thighs both work beautifully here depending on your preference. If using fresh spinach, give it a quick sauté just until wilted; this enhances its flavor and prevents excess moisture. For frozen spinach, make sure it’s fully thawed and well-drained so the casserole doesn’t turn watery.

Step 2: Make the Sauce

In a mixing bowl, blend the softened cream cheese and sour cream with minced garlic, finely chopped onion, salt, pepper, and a pinch of nutmeg if you’re feeling adventurous. Stir until everything melds into a silky, homogenous sauce that will coat every morsel of chicken and spinach with creamy deliciousness.

Step 3: Assemble the Casserole

Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Generously grease your casserole dish to prevent sticking and build layers by combining the shredded chicken, sautéed spinach, and the luscious sauce. Mix just enough to evenly distribute everything without breaking down the textures you worked so hard to prepare!

Step 4: Add Cheese and Bake

Top your layered casserole with shredded mozzarella and freshly grated Parmesan cheese for that gorgeous golden crust. Bake uncovered for 25 to 30 minutes until the top bubbles with cheesy goodness and develops a lovely golden color—signaling it’s ready to come out of the oven.

Step 5: Serve and Enjoy

Let the Creamy Chicken and Spinach Casserole cool for a few minutes so it sets up just right, then dig in! The first bite is creamy comfort elevated by fresh spinach and chicken’s hearty texture, making it a standout dish for any occasion.

How to Serve Creamy Chicken and Spinach Casserole

Garnishes

A sprinkle of fresh chopped parsley or basil adds a beautiful pop of color and fresh herbal brightness that enhances the casserole’s creamy richness. For a bit of crunch, toasted breadcrumbs or crushed nuts on top right before serving create wonderful texture contrast.

Side Dishes

This casserole pairs wonderfully with crisp salads, roasted vegetables, or a simple garlic bread to mop up any leftover sauce. Rice or quinoa also works perfectly if you want to turn it into a fuller, more filling meal for your family or guests.

Creative Ways to Present

Serve individual portions in small ramekins for a charming presentation, perfect for dinner parties or meal prep. You can even scoop it onto buttery toasted crostini for an upscale appetizer twist that’s sure to wow your crowd.

Make Ahead and Storage

Storing Leftovers

Once cooled, store any leftover Creamy Chicken and Spinach Casserole in an airtight container in the refrigerator for up to 3 days. This casserole holds up beautifully and tastes just as comforting the next day.

Freezing

If you want to save some for later, freeze the casserole in a freezer-safe dish before baking or after baking and cooling completely. Wrap tightly to avoid freezer burn and keep it fresh for up to 2 months.

Reheating

Reheat leftovers covered in the oven at 350 degrees Fahrenheit (175 degrees Celsius) until warmed through, about 15-20 minutes. Microwaving works well too for single servings, just be sure to heat evenly and stir halfway through.

FAQs

Can I use frozen spinach instead of fresh?

Absolutely! Just be sure to thaw and squeeze out as much liquid as possible to keep the casserole from getting watery while still enjoying that lovely spinach flavor and color.

What can I add for extra vegetables?

Sliced mushrooms or artichoke hearts are great mix-ins that add more texture and nutrition. You could also toss in roasted red peppers or sun-dried tomatoes for a flavor boost.

Is this casserole freezer-friendly?

Yes, it freezes very well. Either freeze before baking and then bake from frozen (just add a few extra minutes) or freeze after baking and reheat when ready to enjoy.

Can I substitute sour cream?

You can try Greek yogurt as a tangy, protein-packed substitute, though the texture might be slightly less rich. Just use the same amount to maintain balance in the sauce.

What’s a good protein option besides chicken?

Rotisserie chicken is super convenient, but cooked turkey or even shredded pork could be delicious alternatives that work beautifully with the creamy spinach base.
