This Hash Brown Casserole with Corn Flakes is a cheesy, creamy comfort food classic - and it's perfect for holidays, potlucks. .The buttery cornflake topping is what makes it extra special (and the reason people always ask for the recipe).
I've been making this corn flake topped hash brown casserole for years, and it's consistently one of our most popular casserole recipes. Shredded hash browns, cream of chicken soup, sour cream, and plenty of cheese bake into a rich, cozy casserole with a crispy topping that everyone loves.
This is the kind of casserole that works just as well for a holiday dinner as it does for a weekend brunch. It's simple, reliable, and made with ingredients most of us already have on hand. Once you try it, it tends to become one of those recipes you keep coming back to.

You may have also heard this dish called funeral potatoes, since it's a comforting hash brown casserole often served at potlucks and family gatherings.

Ingredients For Potato Casserole With Corn Flakes
- Hash brown potatoes - Shredded hash browns work best. Be sure to thaw them first so the casserole doesn't turn watery.
- Cream of chicken soup - Helps bind the casserole and creates a creamy base.
- Sour cream - Adds richness and a slight tang to balance the cheese.
- Cheddar cheese - Sharp cheddar adds the most flavor, but a cheddar jack blend works too. Pre-shredded is fine, or grate your own if you prefer.
- Onion - Finely chopped. A white or yellow onion both work well.
- Butter - Tossed with the cornflakes so the topping bakes up golden and crisp.
- Corn flakes - Crushed for a crunchy topping with just a hint of sweetness.

How This Hash Brown Casserole Comes Together
This casserole starts with thawed shredded hash browns mixed with a creamy base of soup, sour cream, cheese, and onion. Make sure the hash browns are fully thawed before mixing - excess moisture can make the casserole watery.
Once everything is combined, the mixture should be thick and evenly coated, not soupy. If it looks overly wet, the hash browns likely need to drain a bit longer. Spread the mixture evenly into a greased baking dish, pressing it down lightly so it bakes evenly.
At this point, you can cover and refrigerate it overnight if you're making it ahead. Just wait to add the cornflake topping until right before baking so it stays crisp.

For the topping, toss crushed cornflakes with melted butter and sprinkle them evenly over the casserole. As it bakes, the edges will begin to bubble and the top will turn golden brown. If the cornflakes start browning too quickly, loosely tent the dish with foil for the last 10-15 minutes. You're looking for a hot, creamy center and a crisp, buttery topping.

Tips for the Best Hash Brown Casserole
- Make sure the hash browns are fully thawed and any excess moisture is drained before mixing. This helps prevent a watery casserole.
- If you're making this ahead, wait to add the cornflake topping until just before baking so it stays crisp.
- Crush the cornflakes gently - you want some texture, not fine crumbs.
- For extra flavor, stir in a handful of shredded sharp cheddar on top before adding the cornflakes.
- If serving for brunch, this pairs especially well with eggs and fresh fruit to balance the richness.

Hash Brown is one of my family favorite dish any day. But have never tried it with this amazing and unique topping of Corn flakes.
Slee says
This casserole is a favorite for our church dinners. We make 2 large pans and NEVER have any left over. I guess we should start making 3 large pans! Thank you for sharing.
Sarah says
I made a very similar recipe to this today, but had a problem with the corn flake crust, so I looked online and found your recipe, and I thought maybe you could help me. The casserole was great, but the cornflake topping was not crunchy/crispy...instead it was kind of tough and chewy. I used 1 1/2 cups of crushed cornflakes and 3 TBS of melted butter, except I meted the butter stove-top, then mixed in the cornflakes. Do you think that might be the problem? Because you say to put the dry cornflakes on the casserole first, then pour the butter over top. Doing it this way would seem to not get all the cornflakes fully wet and immersed into the butter...so is that the key? I cooked on 350 for 50 minutes. Thanks for any advice you can give!

Vicky says
Thanks for the kind words!
Sumer says
I'm absolutely doing this for dinner tonight! Going to throw in some breakfast sausage so the meat eaters won't complain but this looks delicious!!!!
Ashley says
How did adding meat to it work out? Has anyone tried adding eggs as well?
P. Casey says
Oven failure. Company coming. I have casserole ready to go. It needs to have cornflake topping added. then baked. Can it be salvaged by doing in microwave?
Vicky says
Oh my gosh, what a nightmare. So sorry to hear the oven gave out. Never tried it in the microwave. If you did, please let me know how it turned out.
Cody says
I wouldn't think so, but who am I? I'm no cook. The cornflakes would be gross and chewy, I'm pretty sure. They need real heat. Sorry for reviving a zombie thread.
Halle says
Can I separate into two dishes and freeze one dish (prior to baking) for future use?
Vicky says
I have never tried that. If you do, please report back and let us know how it worked.
