When you need a dinner that feels comforting, creamy, and easy enough for a weeknight, this Spinach Chicken Casserole with Cream Cheese and Mozzarella is exactly the kind of recipe to keep on repeat. It takes tender shredded chicken, fresh spinach, and a rich, cheesy sauce, then bakes everything together until hot, bubbly, and golden on top. It is the kind of dish that feels hearty and satisfying without requiring a complicated ingredient list or a lot of prep.

This casserole has everything people love in a baked dinner. The cream cheese creates a velvety base, the sour cream adds tang and richness, and the mozzarella melts beautifully into every bite. The spinach gives the casserole color and balance, while the breadcrumb topping adds just enough texture to keep things interesting. Whether you are using leftover chicken, rotisserie chicken, or meal-prepped shredded chicken, this is one of those recipes that makes dinnertime feel simple and cozy.

Why I Love This Recipe

I love this recipe because it turns a handful of basic ingredients into something that tastes like real comfort food. It feels warm, creamy, and filling, but the spinach keeps it from feeling too heavy. It is one of those casseroles that works equally well for busy weeknights, meal prep, or taking to a friend who could use a homemade dinner.

Another reason this recipe stands out is how flexible it is. You can make it a little spicier with red pepper flakes, swap in different cheeses, or serve it over rice, pasta, or roasted vegetables depending on what your family likes. It is forgiving, practical, and exactly the kind of reliable dinner recipe I always appreciate having in my back pocket.

Ingredients

• 2 cups cooked chicken, shredded
• 2 cups fresh spinach, chopped
• 8 ounces cream cheese, softened
• 1 cup mozzarella cheese, shredded
• 1/2 cup sour cream
• 1/2 cup chicken broth
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• Salt and pepper, to taste
• 1/2 teaspoon red pepper flakes, optional
• 1/2 cup breadcrumbs, for topping

Swaps and Notes

This casserole is easy to adjust, which makes it even more useful on busy nights.

• Chicken: Rotisserie chicken is an excellent shortcut here, but any cooked shredded chicken works.
• Spinach: Fresh chopped spinach is great, though thawed frozen spinach can be used if it is squeezed very dry first.
• Mozzarella: You can swap in Monterey Jack, provolone, or a mozzarella-cheddar blend for a slightly different flavor.
• Sour cream: Plain Greek yogurt can work in place of sour cream if you want a tangy alternative.
• Breadcrumbs: Panko breadcrumbs will give you a slightly crispier topping.
• Heat: Red pepper flakes are optional, but they add a nice little kick that balances the richness.

How to Make Spinach Chicken Casserole with Cream Cheese and Mozzarella

1. Preheat your oven to 375°F and lightly grease a medium baking dish.
2. In a large mixing bowl, combine the softened cream cheese, sour cream, and chicken broth. Stir until smooth and creamy.
3. Add the garlic powder, onion powder, salt, pepper, and red pepper flakes if using. Mix well.
4. Fold in the shredded chicken, chopped spinach, and shredded mozzarella cheese. Stir until everything is evenly coated in the creamy mixture.
5. Transfer the mixture to the prepared baking dish and spread it into an even layer.
6. Sprinkle the breadcrumbs evenly over the top.
7. Bake for 25 to 30 minutes, or until the casserole is hot and bubbly and the top is lightly golden.
8. Let it rest for 5 minutes before serving so the filling can settle slightly.

The finished casserole should be creamy and cheesy underneath with a lightly crisp topping that makes every serving extra satisfying.

Tips for Success

Make sure the cream cheese is softened before mixing. This makes it much easier to create a smooth sauce and prevents lumps in the casserole.

Do not overpack the spinach. Two cups of chopped fresh spinach will wilt down nicely in the oven, but if you use frozen spinach, be sure to squeeze out as much moisture as possible so the casserole does not turn watery.

If you want a more golden topping, you can place the casserole under the broiler for the last minute or two. Just watch it closely so the breadcrumbs do not brown too fast.

Storage and Leftover Tips

Store leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave, or warm the casserole in the oven at 325°F until heated through.

This dish also works well for meal prep. You can assemble it ahead of time, cover it, and refrigerate before baking. If baking straight from the refrigerator, you may need to add a few extra minutes to the cook time. Leftovers are also delicious spooned over rice or pasta for an easy next-day lunch.
