1 teaspoon kosher salt, plus more to taste
1/2 teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon Italian seasoning or dried oregano and basil mix

Cream cheese sauce

1/2 cup chicken broth or stock
1 teaspoon Dijon mustard
3 cloves garlic, minced, or 1 extra teaspoon garlic powder
1/2 teaspoon smoked paprika or regular paprika
1/4 teaspoon crushed red pepper flakes, optional for a mild kick
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese

Spinach and mix-ins

8 to 10 ounces fresh baby spinach, roughly chopped

How to Make Chicken and Spinach Casserole with Cream Cheese

Step 1: Prep the oven and pan

Preheat your oven to 375°F. Grease a 9×13 inch baking dish with a little oil or butter so nothing sticks. Set the dish aside while you cook the chicken and mix the sauce.

Step 2: Cook the chicken

Heat 1 tablespoon of oil in a large skillet over medium high heat. Season the chicken pieces with salt, pepper, garlic powder, onion powder, and Italian seasoning. Add the chicken to the hot skillet in a single layer and cook for 5 to 7 minutes, stirring once or twice, until the pieces look golden and cooked through.

If the skillet feels crowded, cook the chicken in two batches so it browns instead of steaming. Turn off the heat and set the cooked chicken aside.

Step 3: Sauté the onion and spinach

In the same skillet, add a small splash of oil if the pan looks dry. Add the diced onion and cook over medium heat for 3 to 4 minutes until it softens and turns lightly golden. Add the chopped spinach in handfuls and stir as it wilts, which takes about 2 to 3 minutes.

If you use frozen spinach, add it after the onion softens and stir until it warms through. Season the spinach mixture with a pinch of salt and pepper, then remove the skillet from the heat.

Step 4: Mix the cream cheese sauce

In a medium bowl, add the softened cream cheese, sour cream or Greek yogurt, and chicken broth. Whisk until the mixture turns smooth and creamy. Add Dijon mustard, minced garlic, paprika, red pepper flakes if you use them, and a pinch of salt and pepper.

Stir in 1 cup shredded mozzarella and 1/2 cup Parmesan until they blend into the sauce. Taste a small spoonful and adjust the seasoning so it matches your preference.

Step 5: Assemble the casserole

Spread the cooked chicken evenly in the greased baking dish. Spoon the spinach and onion mixture over the chicken and spread it out. If you use artichoke hearts, scatter them over the spinach layer.

Pour the cream cheese sauce over everything and use a spatula to nudge it into the corners. Gently stir in the dish so the sauce coats the chicken and spinach without splashing over the sides. Smooth the top so the casserole bakes evenly.

Step 6: Add the cheesy topping

In a small bowl, mix the remaining 1/2 cup mozzarella, 1/4 cup Parmesan, panko breadcrumbs, and melted butter or oil. Stir until the crumbs look evenly coated and slightly clumpy. Sprinkle this mixture evenly over the top of the casserole.

This topping gives you that crunchy, cheesy lid that makes casseroles feel special. If you prefer a lighter version, skip the crumbs and just use a thin layer of cheese.

Step 7: Bake

Place the baking dish on the middle rack of the oven. Bake at 375°F for 20 to 25 minutes until the casserole bubbles around the edges and the top looks golden. If the top browns too quickly, tent the dish loosely with foil and keep baking until the center feels hot.

If you want extra color, switch the oven to broil for 1 to 2 minutes at the end and watch closely so the topping does not burn. Remove the casserole from the oven and let it rest for 5 to 10 minutes so the sauce thickens slightly.

Step 8: Serve

Scoop the Chicken and Spinach Casserole with Cream Cheese into bowls or onto plates. Garnish with chopped fresh parsley or green onions if you like a fresh pop of color. Serve it hot while the cheese stretches and the sauce tastes velvety.

Storage Success

Let the Chicken and Spinach Casserole with Cream Cheese cool to room temperature, then cover the dish tightly or portion it into airtight containers. Store it in the refrigerator for up to 3 to 4 days. Reheat portions in the microwave or in a covered dish in a 350°F oven until hot and bubbly. If the sauce thickens a lot in the fridge, stir in a splash of milk or broth during reheating to bring back that silky, creamy texture.
