This recipe is designed to be make-ahead, a true lifesaver for busy holiday hosts.

Prepare for a truly satisfying experience with this hearty Mashed Potato Casserole. Each spoonful offers a harmonious balance of savory, tangy notes from the cheeses and dairy, complemented by aromatic onion and garlic powder, and a subtle warmth from smoked paprika and a touch of cayenne pepper.
