Chicken and Spinach Casserole with Cream Cheese

I’ve been making this chicken and spinach casserole with cream cheese for years, and it never fails to impress my family. The combination of tender chicken, vibrant spinach, and rich cream cheese creates a dish that’s both comforting and nutritious. What I love most is how simple it is to throw together, especially when I use leftover rotisserie chicken from the weekend.

This casserole has become my go-to solution for busy weeknights when I need something hearty on the table fast. The creamy texture from the cream cheese and sour cream makes even picky eaters forget they’re eating spinach. I remember the first time I served this chicken and spinach casserole with cream cheese to my kids. They were skeptical about the green specks, but after one bite, they were hooked. Now they request it at least twice a month. It’s also perfect for meal prep since the leftovers taste even better the next day, and you can easily double the recipe for potlucks or family gatherings.

What You’ll Need for This Creamy Chicken Casserole

Before you start, gather all your ingredients so assembly goes smoothly. I always use rotisserie chicken to save time, but any cooked chicken works beautifully in this recipe.

• 2 cups cooked chicken, shredded or diced
• 1 (10 oz) package frozen chopped spinach, thawed and drained
• 8 oz cream cheese, softened (I prefer full-fat for the richest flavor)
• 1/2 cup sour cream
• 1/4 cup mayonnaise
• 1/4 cup grated Parmesan cheese
• 1/4 cup chopped onion
• 2 cloves garlic, minced
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon paprika
• 1/2 cup shredded mozzarella cheese (for topping)
• 1/4 cup breadcrumbs (for topping)

Pro tip: Make sure your cream cheese is completely softened at room temperature. This makes mixing much easier and prevents lumps in your chicken and spinach casserole with cream cheese.

Step-by-Step Instructions for Perfect Results

I recommend reading through all the steps before you begin so you know what to expect. This chicken and spinach casserole with cream cheese comes together quickly once you start.

Step 1: Preheat your oven to 350°F (175°C) and grease a 9×9 inch baking dish (or similar 2-quart baking dish) with butter or cooking spray. I like using butter because it adds a subtle richness to the edges of the casserole.

Step 2: In a large mixing bowl, combine the softened cream cheese, sour cream, mayonnaise, Parmesan cheese, chopped onion, minced garlic, salt, pepper, and paprika. Mix with a sturdy spoon or hand mixer until the mixture is smooth and well blended. The cream cheese should be completely incorporated with no visible chunks. If you see lumps, keep mixing for another minute.

Step 3: Squeeze the thawed spinach in a clean kitchen towel or several layers of paper towels to remove excess moisture. This step is critical because watery spinach will make your casserole soggy. I usually squeeze until no more liquid comes out (you should extract at least 1/2 cup of liquid). Add the spinach and shredded chicken to the cream cheese mixture and stir until everything is evenly coated in the creamy sauce.

Step 4: Transfer the chicken and spinach mixture to your prepared baking dish. Use a spatula to spread it evenly across the pan, smoothing the top so it bakes uniformly.

Step 5: In a small bowl, combine the shredded mozzarella cheese and breadcrumbs. Sprinkle this mixture evenly over the top of the casserole. The cheese will melt and bubble while the breadcrumbs turn golden and crispy.

Step 6: Bake for 25 to 30 minutes, or until the casserole is hot and bubbly around the edges and the topping is golden brown. You’ll know it’s ready when you can see the sauce bubbling up along the sides and the center reaches 165°F. If you want an extra crispy top, broil for the last 1 to 2 minutes, but watch it carefully to prevent burning.

Step 7: Let the chicken and spinach casserole with cream cheese cool for about 5 minutes before serving. This allows the sauce to thicken slightly and makes serving much easier.

Perfect Pairings for Your Casserole

This creamy chicken and spinach casserole pairs wonderfully with light, fresh sides that balance its richness.

Simple Green Salad: A crisp salad with vinaigrette cuts through the creaminess and adds a refreshing crunch. I love using mixed greens, cherry tomatoes, and cucumber with a lemon vinaigrette.

Garlic Bread: Crusty garlic bread is perfect for soaking up any extra cream cheese sauce on your plate. The buttery, garlicky flavor complements the chicken and spinach beautifully.

Roasted Vegetables: Try roasted broccoli, carrots, or green beans for added nutrition and color. The slight char from roasting adds a nice contrast to the smooth casserole texture.

Rice or Quinoa: Serve this chicken and spinach casserole with cream cheese over fluffy rice or quinoa to make it even more filling. The grains absorb the creamy sauce wonderfully.

Steamed Asparagus: Fresh asparagus with a squeeze of lemon adds elegance and pairs perfectly with the savory flavors in this dish, especially during spring.

More Comforting Chicken Dinners to Try

This chicken and spinach casserole with cream cheese is perfect for cozy weeknight meals, and there are plenty of other hearty chicken dishes that deliver the same comfort. For another creamy option, try the Crispy Parmesan Chicken with Rich Garlic Sauce which features a similar rich, garlicky profile with a crispy coating that contrasts beautifully with the creamy sauce.

When you want to set it and forget it, the Crock Pot Crack Chicken offers that same creamy, cheesy goodness with minimal effort. For soup lovers, the Creamy Rotisserie Chicken Mushroom Soup and Green Chicken Enchilada Soup both provide warming, protein-packed meals that pair perfectly with crusty bread, just like this casserole.

Storing and Reheating Your Chicken Casserole

Store leftover chicken and spinach casserole with cream cheese in an airtight container in the refrigerator for up to 3 to 4 days. I actually think it tastes better the next day after the flavors have had time to meld together. For longer storage, you can freeze this casserole in a freezer-safe container for up to 3 months.

When reheating, I recommend using the oven at 350°F (175°C) until warmed through, about 15 to 20 minutes. Cover with foil to prevent the top from over-browning. You can also microwave individual portions for 2 to 3 minutes, stirring halfway through for even heating.

Pro tip: If the casserole seems dry after refrigeration, add a tablespoon of milk or chicken broth before reheating to restore its creamy texture. This chicken and spinach casserole with cream cheese also freezes beautifully if you want to make it ahead for busy weeks.
