Now this is an all-in-one breakfast! This easy Hash Brown Casserole with Corn Flakes is loaded with breakfast favorites, all baked into one casserole.

It’s also known as Cheesy Hash Brown Casserole or Funeral Potatoes, because it’s a popular dish at funerals in the South.

Personally, I love serving it for a make-ahead brunch (alongside my Overnight French Toast Casserole)—just prepare the night before and bake it in the morning.

It’s a real crowd pleaser, because it has something for everyone! Hash browns, cheese, tender sautéed bell peppers and onions, and a creamy sauce made with sour cream and cream of mushroom soup are all loaded into this casserole, and it’s topped with buttery corn flakes.

It’s an explosion of breakfast flavors and textures, in the best possible way. And it’s seriously CHEESY!

Along with Cherry Coffee Cake and some Praline Candied Bacon, it’ll be the star of your next brunch.
