How to Make Creamy Chicken and Spinach Casserole with Cream Cheese

1. Preheat oven

Heat oven to 375°F (190°C).

2. Sauté the aromatics (optional but recommended)

In a small skillet, sauté diced onion and garlic in a little butter or oil until softened. This adds depth of flavor.

3. Mix the creamy sauce

In a large mixing bowl, combine softened cream cheese, chicken broth, and heavy cream. Mix until smooth. Add parmesan, paprika, salt, pepper, and Italian seasoning if using.

4. Add the chicken and spinach

Fold in cooked chicken, sautéed onion and garlic, and chopped spinach. Stir until everything is coated in the creamy sauce.

5. Add cheese

Fold in half of the mozzarella.

6. Transfer to a baking dish

Spread mixture into a greased 9×13 baking dish. Smooth the top.

7. Add final cheese layer

Top with remaining mozzarella and extra parmesan if desired.

8. Bake

Bake 25–30 minutes, until bubbly and golden on top with melted cheese.

9. Serve hot

Let the casserole rest for 5 minutes before serving so the sauce thickens slightly.

Tips for the Best Creamy Chicken and Spinach Casserole

Use softened cream cheese

Cold cream cheese doesn’t mix well and creates lumps.

Fresh spinach works best

Frozen can be used, but must be squeezed very dry to avoid watery sauce.

Rotisserie chicken saves time

Shredded rotisserie chicken adds flavor and cuts prep time in half.

Add a crunchy topping

Crushed Ritz crackers, breadcrumbs, or fried onions add amazing texture.

Make it low carb

Use only chicken, spinach, cheese, and sauce. Skip any starch add-ins.

Flavor Variations

Bacon Spinach Chicken Casserole

Add ½ cup crispy bacon pieces.

Chicken Alfredo Spinach Bake

Swap mozzarella for parmesan and add more cream.

Broccoli Chicken Spinach Casserole

Add 2 cups cooked broccoli florets.

Mushroom Chicken Spinach Casserole

Stir in sautéed mushrooms for extra savory flavor.

Spinach Artichoke Chicken Casserole

Add chopped artichokes and extra parmesan for creamy dip vibes.

Serving Suggestions

• Garlic bread
