This cheesy Hash Brown Casserole with Corn Flakes has all the good stuff: tender hash browns, a creamy sauce, lots of cheese, breakfast sausage, and corn flakes on top for crunch!
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!

How to make hash brown casserole with corn flakes
Start by sautéing breakfast sausage until browned and cooked through. Crumble it as it cooks.
Remove the sausage but keep any drippings in the pan. Use the drippings to sauté the bell peppers and onion.
I used half of a red pepper and half of a green pepper. You can use any color bell pepper that you like.
While the veggies cook, whisk together the sour cream and the cream of chicken soup in a very large bowl (use the largest bowl in your kitchen!).
Add the defrosted hash browns, cooked sausage, sautéed veggies, salt, and cheese. Mix thoroughly to combine.
Place the mixture into a greased 13×9 inch pan.
Toss the corn flakes with the melted butter.
Top the casserole with the corn flake mixture, and bake for 40–45 minutes, or until the corn flakes are beginning to turn brown on top.
Let the hash brown casserole cool for 5–10 minutes before serving.
Can I make hash brown casserole in advance?
You can easily make hash brown casserole in advance. Assemble the casserole but leave off the corn flake topping, and do not bake it. Refrigerate the casserole, covered, for up to 24 hours.
When you’re ready to bake it, let the casserole set at room temperature for 30 minutes, then top with the corn flake topping. Bake as directed.
- Use ground beef or cooked chicken (such as rotisserie chicken) in place of the breakfast sausage. You can also add ½ lb of cooked and crumbled bacon.
- Use whichever color bell pepper that you like.
- Swap the cheddar cheese for your favorite shredded cheese, such as swiss, colby jack, etc.
- Use cream of mushroom or cream of celery soup in place of the cream of chicken soup.
- Substitute Ritz crackers crumbs (1–2 cups) for the corn flakes.
Frequently Asked Questions
