Cheesy Hashbrown Potato Casserole is a great addition to any meal! It’s pure comfort food that’s easy to make and is always a crowd-pleaser at family gatherings, potlucks, and a must for breakfast or brunch.
It’s really hard for me to think of a potato dish that I don’t love. Whether it’s an Air Fried Baked Potato, Scalloped Potatoes are Twice Baked Sweet Potatoes, I’m a fan!
That’s why it was fitting that I add this recipe to my list of potato recipes. Hashbrown Casserole is a classic recipe that’s been around for years. I’ve skipped the gloppy canned soup and put my own spin on things with the addition of 2 kinds of cheese and extra seasoning for a mix of flavors that are outstanding.
Cheesy Hashbrown Potato Casserole is a smash hit side dish that not only is easy to make but can also be prepped and made ahead of when you want to serve it.
Ingredients You Need For This Recipe

Can This Recipe Be Made Ahead Of Time?
You bet! Just make it the evening before you want to serve it, wrap with foil or plastic wrap and store in the refrigerator. When you are ready to serve, take it out of the oven, and bake.
You can also make it ahead and freeze! Put the casserole together ahead of time, tightly cover with plastic wrap then in tin foil then freeze. Thaw completely and proceed to cook per instructions.

Can you use fresh grated potatoes?
Sure – make sure to squeeze out any liquid.
Does the casserole look “curdled” after it comes out of the oven???
Hey there Diane!
Thank you for your interest in the recipe! After it comes out of the oven it should look more like the pictures I included on the post. The texture will come out pretty soft and creamy from the potatoes and sour cream in the middle with crispy edges and a nice cheesy top. I hope you like the recipe, let me know how it goes!
Can I use the dehydrated hashbrowns from Costco? Should I reconstitute them?
Yep, I’d do that. You’ve got instincts, Tamara. Let me know how it turns out.
Have a great day,
Can I add pork sausage or ground beef to this?
Sure! It sounds like a good idea to me!
Can I make it the night before and leave in the fridge overnight and bake it in the oven in the morning?
Hey Sam. Yes, you sure can make it overnight. It turns out great.
Happy New Year!
Hi! If I’m using bagged hashbrowns, do I need to thaw them first?
Hey Lauren! Yes, thaw the hashbrowns first. When I use frozen, I place them in a mesh strainer and just let them thaw so that any moisture will drip out. Hope this helps! Let me know how the dish turns out.
This is the perfect recipe! Made this and it’s delicious
Thank you so much Melossa! I love it when someone let’s me know about their love of one of my recipes.
This sounds good but I didn’t see what temperature to bake. What temperature?
Thanks Brenda! Bake at 350 degrees. I updated the post as well.
