Ingredients
- Cooked chicken: Use rotisserie or any leftover roasted chicken for maximum flavor and extra tenderness Try to shred or dice consistently for best bites

- Shredded mozzarella cheese: This melts beautifully into the sauce layer Try to buy a block and shred it yourself for best stretch and fewer additives

- Sour cream: Brings creaminess and a little tang to balance all the cheese
- Garlic powder: A hint of savoriness that pairs perfectly with chicken
- Onion powder: Lends quiet depth of flavor The casserole does not taste oniony
