# Expert Advice:

01 -
  • This casserole turns a chilly morning into a gathering spot, thanks to its creamy layers and crispy topping.
  • The prep is mostly mixing and layering, so you’ll have plenty of time to chat or sneak tastes of the cheesy filling.
02 -
  • If you use frozen hash browns without thawing them, the casserole won’t cook evenly and can turn watery.
  • Swapping cornflakes with breadcrumbs once dulled the crunch and the topping lost its charm—cornflakes really make a difference.
03 -
  • Mix the filling gently; over-stirring can make the potatoes mushy.
  • A sprinkle of extra cheese under the cornflakes gives an gooey layer that everyone loves.
