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

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

Instructions
- Step 1: Prepare the ingredients. Cook and shred your chicken if not already cooked. If using fresh spinach, sauté it lightly until wilted. For frozen spinach, thaw completely and drain well.
- Step 2: Make the sauce by combining the softened cream cheese, sour cream, minced garlic, chopped onion, salt, black pepper, and nutmeg (if using) in a mixing bowl. Stir until smooth and well blended.
- Step 3: Preheat your oven to 375°F (190°C). Grease a casserole dish, then layer the shredded chicken, spinach, and creamy sauce inside. Gently mix to combine all ingredients evenly.
- Step 4: Sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the top of the casserole.
- Step 5: Bake uncovered for 25-30 minutes, until the cheese is golden and bubbly. Allow the casserole to cool slightly before serving.
Tips & Variations
- For extra flavor, add sautéed mushrooms or artichoke hearts to the mixture before baking.
- Swap out mozzarella for a sharper cheese like cheddar for a different taste.
- If you prefer a pasta casserole, stir in cooked pasta before baking.
- Use fresh garlic and onions for best flavor, but powdered can work in a pinch.
Storage

FAQs
Can I use chicken thighs instead of breasts?
Yes, both chicken breasts and thighs work well in this recipe. Thighs tend to be juicier and more flavorful, making them a great choice.
Is it necessary to sauté fresh spinach before baking?
Sautéing fresh spinach removes excess moisture and helps prevent the casserole from becoming watery. If using frozen spinach, make sure it is well thawed and drained thoroughly.

Instructions
- Prepare the Ingredients: Cook and shred your chicken if it’s not pre-cooked. If using fresh spinach, sauté it lightly in a pan until wilted. For frozen spinach, make sure to thaw and drain it well to remove excess moisture.
- Make the Sauce: In a mixing bowl, combine the softened cream cheese, sour cream, minced garlic, finely chopped onion, salt, black pepper, and a pinch of nutmeg if using. Stir thoroughly until the mixture is smooth and evenly blended.
- Preheat the Oven: Set your oven to 375°F (190°C) to ensure it reaches the desired temperature by the time your casserole is assembled.

Notes
- You can substitute cooked chicken thighs for breasts to add a richer flavor and moist texture.
- For a lower-fat option, use reduced-fat cream cheese and sour cream.
- Fresh spinach should be cooked until just wilted to avoid excess water in the casserole.
- If using frozen spinach, be sure to squeeze out all water to prevent a watery casserole.
- Adding sliced mushrooms or artichoke hearts gives extra texture and flavor; cooked pasta can turn it into a heartier dish.
- Letting the casserole rest before serving helps it set and makes serving easier.
