Ingredients

For the Casserole:

2 large chicken breasts (about 1.5 pounds), cooked and shredded or diced
1 tablespoon olive oil (if cooking chicken fresh)
1 teaspoon garlic powder
1/2 teaspoon onion powder
1/2 teaspoon paprika
1/2 teaspoon salt (or to taste)
1/4 teaspoon black pepper
4 oz (115g) cream cheese, softened
1/2 cup sour cream (or Greek yogurt)
2 cups fresh spinach (or 1 cup cooked spinach, drained well)
1 cup shredded mozzarella cheese
1/4 cup grated Parmesan cheese (optional for extra flavor)
1 teaspoon Italian seasoning or dried oregano
1/2 teaspoon crushed red pepper flakes (optional, for a little heat)

Optional Toppings:

Extra mozzarella for topping (1/2 cup)
Fresh parsley or basil for garnish

Directions

1. Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish (8×8-inch or similar) with a bit of butter or oil.

2. Cook the Chicken (if not already cooked)

In a skillet, heat 1 tablespoon of olive oil over medium heat. Season chicken breasts with garlic powder, onion powder, paprika, salt, and pepper.
Cook chicken for 5–6 minutes per side, or until fully cooked (internal temp 165°F/74°C). Remove and let rest for 5 minutes before shredding or dicing.

3. Prepare the Creamy Mixture

In a large mixing bowl, combine cream cheese, sour cream, Italian seasoning, red pepper flakes (if using), and Parmesan cheese. Mix until smooth.
Fold in the fresh spinach, cooked chicken, and half of the mozzarella. Stir until evenly mixed.

4. Assemble the Casserole

Transfer the creamy chicken and spinach mixture into your prepared baking dish. Spread it out evenly with a spatula.
Top with the remaining mozzarella cheese and an extra sprinkle of Parmesan if desired.

5. Bake

Bake uncovered in the preheated oven for 25–30 minutes, or until the cheese is bubbly and golden on top.

6. Garnish and Serve

Let rest for 5 minutes. Garnish with fresh chopped parsley or basil before serving.
