Ingredients

Scale
  • 2 cups cooked chicken breast, shredded or cubed
  • 3 cups fresh spinach, chopped
  • 1 cup heavy cream
  • 1 cup sour cream (or Greek yogurt for a lighter option)
  • 1 ½ cups shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon paprika
  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt (adjust to taste)
  • ½ teaspoon black pepper
  • 1 tablespoon olive oil
  • ½ cup chicken broth
  • ½ teaspoon red pepper flakes (optional, for spice)
  • ½ cup cooked bacon bits (optional, for extra flavor)

Ingredient Highlights

 

  • Chicken: Use pre-cooked shredded or cubed chicken for convenience. Rotisserie chicken works great!
  • Spinach: Fresh spinach adds nutrients, but frozen spinach (thawed and drained) can be used as well.
  • Cheese: Mozzarella provides creaminess, while Parmesan adds a rich, savory depth.
  • Heavy Cream & Sour Cream: These create a luxuriously creamy sauce that binds the casserole together.
  • Seasonings: Italian seasoning, garlic, and paprika enhance the flavors without overpowering the dish.

Instructions

Prepare the Ingredients:

  1. Preheat the Oven: Set your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil or cooking spray.
  2. Cook the Spinach: In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the chopped spinach and sauté for 2-3 minutes until wilted. Remove from heat.
  3. Mix the Sauce: In a large bowl, combine heavy cream, sour cream, chicken broth, garlic powder, onion powder, paprika, Italian seasoning, salt, and pepper. Stir until well blended.
  4. Assemble the Casserole: In the greased baking dish, layer the cooked chicken evenly. Add the sautéed spinach on top. Pour the creamy sauce over the mixture, ensuring everything is evenly coated.
  5. Add the Cheese: Sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the casserole. If using bacon bits, sprinkle them on top for extra flavor.

Bake the Casserole:

 

  1. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly.
  2. Broil for a Golden Top (Optional): For a golden, crispy cheese layer, broil the casserole for an additional 2-3 minutes.
  3. Rest Before Serving: Let the casserole sit for 5 minutes before serving to allow the flavors to meld together.
