Ingredients

2-3 cups cooked and shredded chicken (breasts or thighs work great)
4 cups fresh spinach or 1 package frozen spinach (thawed and drained)
8 ounces cream cheese (softened)
1/2 cup sour cream
1 cup shredded mozzarella cheese
1/4 cup grated Parmesan cheese
2 cloves garlic (minced)
1 small onion (finely chopped)
1/2 teaspoon salt
1/4 teaspoon black pepper
Pinch of nutmeg (optional)
Sliced mushrooms, artichoke hearts, or cooked pasta (optional)

Instructions

Step 1: Prepare the ingredients by cooking and shredding chicken if it’s not pre-cooked. For fresh spinach, sauté lightly until wilted; if using frozen spinach, thaw and drain well.
Step 2: In a mixing bowl, combine cream cheese, sour cream, minced garlic, finely chopped onion, salt, black pepper, and nutmeg if using. Stir until smooth and well blended.
Step 3: Preheat your oven to 375°F (190°C). Grease a casserole dish and layer the shredded chicken, spinach, and creamy sauce. Mix gently to combine evenly.
Step 4: Sprinkle shredded mozzarella and grated Parmesan cheese evenly over the top of the casserole.
Step 5: Bake uncovered for 25-30 minutes, or until the top is golden and bubbly. Remove from oven and let cool slightly before serving.

Tips & Variations

For extra flavor, add sliced mushrooms or artichoke hearts to the casserole before baking.
Mix in cooked pasta such as penne or rotini to create a more filling meal.
If fresh spinach isn’t available, frozen spinach works well—just be sure to thaw and drain it thoroughly to avoid extra moisture.
Feel free to swap mozzarella cheese for cheddar or a blend of Italian cheeses to vary the taste.

Scale

Chicken and Vegetables

2–3 cups cooked and shredded chicken (breasts or thighs work great)
4 cups fresh spinach or 1 package frozen spinach (thawed and drained)
2 cloves garlic (minced)
1 small onion (finely chopped)
Optional: sliced mushrooms, artichoke hearts, or cooked pasta

Dairy and Cheese

8 ounces cream cheese (softened)
1/2 cup sour cream
1 cup shredded mozzarella cheese
1/4 cup grated Parmesan cheese

Seasonings

1/2 teaspoon salt
1/4 teaspoon black pepper
Pinch of nutmeg (optional)

Instructions

Prepare the Ingredients: Cook and shred your chicken if it’s not already cooked. If using fresh spinach, sauté it lightly in a pan until wilted. For frozen spinach, ensure it is fully thawed and well-drained to prevent excess moisture in the casserole.
Make the Sauce: In a mixing bowl, combine the softened cream cheese, sour cream, minced garlic, finely chopped onion, salt, black pepper, and nutmeg if using. Stir the ingredients until the mixture is smooth and well blended.
Assemble the Casserole: Preheat your oven to 375°F (190°C). Grease a casserole dish. In the dish, layer the shredded chicken, sautéed spinach, and creamy sauce, gently mixing them together to distribute the ingredients evenly.
Add Cheese and Bake: Sprinkle the shredded mozzarella and grated Parmesan cheeses evenly over the top of the assembled casserole. Place the dish in the preheated oven and bake uncovered for 25 to 30 minutes, or until the cheese topping is golden brown and bubbly.
Serve and Enjoy: Allow the casserole to cool slightly before serving. This dish pairs wonderfully with a fresh salad, crusty bread, or rice for a complete and satisfying meal.

Notes

You can substitute cooked pasta for the spinach or add mushrooms or artichoke hearts for extra flavor and texture.
If using frozen spinach, be sure to wring out as much water as possible to avoid a watery casserole.
Adjust seasoning according to taste; adding nutmeg is optional but adds a warm depth to the cream sauce.
Leftovers can be refrigerated for up to 3 days and reheated in the oven to maintain crispy topping.
To make this casserole lighter, consider using reduced-fat cream cheese and sour cream.
