Loaded Twice-Baked Potato Casserole
Fluffy mashed russet potatoes bake together with sour cream, sharp cheddar, and crumbled bacon for a shareable, spoonable twist on the classic loaded potato.

This casserole takes everything wonderful about a loaded baked potato and turns it into a dish the whole table can dig into at once. It bakes up creamy in the middle with a golden, cheesy crust on top, and the bacon and green onions make it feel like a proper indulgence. It pairs with just about anything off the grill or out of the fryer.
