Ingredients
- 2-3 cups cooked and shredded chicken (breasts or thighs)
- 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 add-ins)
Instructions
- Step 1: Prepare the ingredients. Cook and shred your chicken if it’s not already cooked. If using fresh spinach, sauté it lightly until wilted. For frozen spinach, thaw and drain it well.
- Step 2: Make the sauce by combining the cream cheese, sour cream, garlic, onion, salt, pepper, and nutmeg in a mixing bowl. 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, sautéed spinach, and creamy sauce inside. Mix gently to combine everything evenly.
- Step 4: Sprinkle the mozzarella and Parmesan cheese evenly over the top of the casserole. Bake uncovered for 25-30 minutes, or until the top is golden and bubbly.
- Step 5: Let the casserole cool slightly before serving. It pairs wonderfully with a fresh salad, crusty bread, or rice.
