Ingredient Notes

• Chicken breast or thighs: Provides lean protein; thighs add juiciness. Cooked chicken can be shredded or cubed.

• Fresh spinach: Adds a mild, earthy flavor and nutrients; can substitute with frozen spinach (thawed and drained).

• Cream cheese: Creates a creamy texture; can swap with Greek yogurt for lighter version.

• Shredded cheese: Cheddar, mozzarella, or a mix works well. Choose high-quality cheese for best melt.

• Onion and garlic: Build depth of flavor; can use powdered versions if short on time.

• Heavy cream: Adds richness; milk or half-and-half works for a lighter option.

• Breadcrumbs or crushed crackers (optional): For a crunchy topping; Parmesan adds extra flavor.

• Butter or olive oil: Used for sautéing and topping; ensures a golden crust.

How To Make Chicken and Spinach Casserole

1. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish lightly with butter or cooking spray.

2. Cook the chicken. Season 2-3 chicken breasts with salt, pepper, and garlic powder. Sear in a skillet over medium heat for 5-6 minutes per side until golden and cooked through. Remove and let rest before shredding.

3. Sauté aromatics. In the same skillet, add 1 small chopped onion and 2 cloves minced garlic. Cook until softened (about 3 minutes).

4. Wilt the spinach. Add 4 cups fresh spinach to the pan and cook until just wilted. Season with salt and pepper.

5. Make the creamy sauce. Reduce heat and stir in 4 oz cream cheese and 1/2 cup heavy cream until smooth. Add 1 cup shredded cheese and stir until melted. Taste and adjust seasoning.

6. Combine chicken and sauce. Fold shredded chicken into the creamy spinach mixture. Pour into the prepared baking dish.

7. Add topping. Sprinkle remaining 1/2 cup shredded cheese and optional 1/4 cup breadcrumbs on top. Dot with butter for extra crispness.

8. Bake. Place in oven and bake for 25-30 minutes until bubbly and golden brown on top. Let rest 5 minutes before serving.

Helpful tips: Ensure spinach is well-drained to prevent a watery casserole. For extra flavor, add a pinch of nutmeg to the sauce.
