A quick and easy casserole that transforms simple mashed potatoes into a crispy, loaded dish topped with cheese, bacon, green onions, and everything bagel seasoning for a flavorful crunch.
If topping browns too fast, tent loosely with foil halfway through baking. For extra creaminess, whip potatoes with a hand mixer before adding cheese and bacon. Use warm milk to keep mash smooth. Reserve some cheese and bacon for a crispy topping. Leftover mashed potatoes can be used. To get crispier topping, spread evenly and optionally broil for last 1-2 minutes while watching closely.
