How to Make Cheesy Hashbrown Casserole

Not only is this recipe super easy to make, but it’s also easy to make ahead when you use prepared potatoes. It only takes a few minutes to mix together! 

COOK ONIONS Start by preheating the oven to 350 degrees F. In a large pot over medium heat, melt butter, then add green onions, and sauté for about 3 minutes, until onions are tender and fragrant.

MAKE SAUCE  To the pot, add the shredded cheddar cheese, sour cream, and cream of chicken soup. Stir to combine and cook for a few minutes until melted and bubbly. 

PRO TIP: Make sure to use freshly grated cheese, not pre-shredded! Pre-shredded cheese has additives in it to prevent clumping, but those additives can also make the sauce grainy in texture once melted.

ADD POTATOES  Add the shredded potatoes all at once to the cheesy sauce and mix well until the potatoes are evenly coated.

TRANSFER  Pour cheesy potato mixture into a greased 9×13 inch baking dish and set aside. 

MAKE CRUNCHY TOPPING  Add the crushed corn flakes with 1/2 cup melted butter and stir to coat. Spread on top of the potatoes in an even layer.

BAKE  Transfer the pan to the oven and bake for 40-45 minutes or until the center is hot and bubbly. Serve warm. 

How to Make Ahead

This recipe is SO easy to make ahead and bake later! 

To Refrigerate: Make the recipe as directed, then cover and refrigerate for up to 5 days before baking. 

To Freeze: Make the recipe as directed, do not add the cornflakes. Freeze covered in a freezer-safe baking pan for up to 3 months.  Refrigerate overnight to thaw. 

Before baking, add the topping and increase the baking time if needed till the center is hot and bubbly.

What Kind Of Potatoes To Use? 

This recipe uses frozen shredded potatoes or hashbrowns, but you could also use freshly grated potatoes, cubed potatoes fresh or frozen, or thinly sliced potatoes. 

Keep in mind that if you use fresh potatoes, you’ll need to decrease the baking time in order to prevent mushy potatoes. 

Tips and Variations

  • Add 2 cloves of minced garlic to the onion when sauteing in butter for a little extra flavor! 
  • If you don’t like green onions, leave them out. 
  • Add pre-cooked diced ham for more flavor and protein! 
  • Change up the cream of chicken soup! You could use cream of mushroom, cream of celery, or canned cheddar soup for extra cheesy goodness.

  1. Yum! There are tons of similar versions of this classic recipe for a reason…everyone loves it! I don’t make often but when I do I always remember yours and come back to it because your response to the snarky comment about being glad you don’t live at her house made me giggle. So delicious!

  2. Has anyone ever topped with French fried onions? Just curious. This recipe looks amazing. Just not sure about the corn flakes.

    1. The french fried onions would be a great addition to this recipe. I would wait to add them until about 5 minutes left of baking though. No need to toss them with butter. But you should try the corn flakes on top… it’s a game changer!

  3. I was reading this recipe (Cheesy Hashbrown Casserole) and thought I would share this story. When we have a pot luck at work, Pati always bring this recipe but adds cooked breakfast sausage in one pan and crumbled cooked bacon in the other. We start the morning off with this casserole and finish the day with desserts,

  4. Several in my family don’t care for the crunch of onions in this casserole so a few years ago I started substituting french onion dip for the sour cream and not using the raw onions. You still get the flavor and everyone seems to like it better. This was not my original idea, I read it someplace else, but it works for my family.

    1. Brilliant! I don’t care for the crunch of raw onions either. Thank you so much for the idea, now to sell my onion=loving family on the idea…

  5. This looks great. I’m going to add some browned ground beef to the casserole and pair with a salad for supper tonight.

    1. Hi Millete, shredded potatoes are simply hash brown potatoes. You can find them in the frozen section of your grocer.

  6. So are these the widely spoken about funeral potatoes? I am LDS, but did not grow up LDS and have heard (for 29 yrs) about funeral potatoes, but never had them. Apparently, funeral potatoes and those little cheesecake cherry tarts were relied upon so much that people no longer make them for church functions. I have had the cheesecake tarts (only once at a 50’s themed ward party); when I asked for the recipe the whole kitchen laughed. Never did get that recipe. maybe you can help.

    1. Haha!! Yes, these would be considered Funeral Potatoes. I think they’re just a common dish that’s taken to funerals, so they acquired the name over the years. As for the Cherry Cheesecakes… I actually attended a Stake Relief Society function when we were first married, and it was a BIG recipe exchange. Everyone made their favorite easy dish, brought the recipe and then the Presidency printed up cute little books of recipes. I still have mine, and you can see it in the picture above of my recipe box (it’s the group of yellow/orange cards)!! Anyways- the famous Cherry Cheesecakes are in there (a few times), so I should probably share that recipe too. They’re crazy simple, so that’s probably why those people giggled when you asked. I’ll share it on here soon!

  7. Yikes. Terribly high in calories + sodium. I’ve never purchased frozen potatoes. Cannot even remember if I’ve tasted tater-tots. Usually, frozen items are loaded with salt, fat and all sorts of other junk. To taste (if someone else prepared!) would be okay. I’d never make this dish. On the other hand, give me a bowl of corn flakes! I’m happy.

    1. Best answer ever! Shawn, I have tried several of your recipes already and they all were a huge success with my family. I am making this one tonight and I am absolutely excited and sure it’s going to be just as good as the others 🙂
      Thank you for sharing this recipe with us!

    2. This recipe is so easily adaptable Marcee is really missing out. I used fresh shredded potatoes and low fat sour cream and fat free soup. It was awesome. Thanks for sharing we love it!

    3. Marcee, please keep your negative comments to yourself. You are not the food police!!

    4. 5 stars
      Hi Marcee,

      It isn’t necessary to use frozen potatoes. Just grate fresh potatoes and use them. I realize that I am responding to a 2014 post, but that is always an option…

  8. Those crispy cornflakes are what really make this casserole amazing! I remember my mom making this almost every Sunday. 🙂

  9. I wasn’t expecting to read this recipe and see some version of a million other recipes. Wrong! Wow this one is totally different. And easy. Breakfast for some reason possibly is my most favorite meal. Not sure why.
    But I like the fact this one is make ahead, so you can concentrate on the eggs or sit around and drink coffee! Right, like women and/or cooks do much of that. Smiles—-
