“Best Potatoes ever! Not many ingredients and easy recipe.” – Terry
Be sure to scroll down to the recipe card for complete measurements.
- Hashbrowns – thawed or frozen will work just fine. We prefer the cubed hashbrowns, but the shredded hash brown potatoes will also work, just a different texture. You could also shred your own potatoes!
- Cream of Chicken Soup
- Sour Cream – provides that creamy base!
- Minced Onion- the dried type. Or you can swap it out for chopped onion if you prefer.
- Cheese – a good cheddar cheese is what you’ll need for best flavor.
- Corn Flakes – provides the perfect crunchy topping. You can also use ritz crackers (like we do with our homemade mac and cheese). Cracker barrel hashbrown casserole is topped with shredded cheese and no cornflakes.
How to Make Hashbrown Casserole
- Mix it all in a large bowl.
- Pour it in a pan. We use a 13×9 baking dish.
- Add the topping. Lightly crush the cornflakes, avoid turning them into crumbs!
- Bake. Cover the casserole dish with foil and bake until bubbly.

Best cheesy potato casserole I’ve even made. Easy too!
We use potato O’Brien instead of hash browns. It already has the onion and we love the green peppers too!
ps…mix and freeze a week?! I freeze from Thanksgiving to Christmas or longer every year…..NO PROBLEMS.
I too have been making these for years. Only two of us now so I know about freezing them…GREAT! I do not care for cheddar as much so I use half Swiss or motz. Saltines mixed with butter for top are good too.too
So stinking good! These stuff is addicting
Wow!! Yum. Can you freeze any leftovers? Thanks.
What are your thoughts on mixing and freezing a week in advance?
My favorite side dish for every occasion….we use cornflakes too!
Love the corn flakes idea, can’t wait to try your version the next time I make these potatoes. YUM!
I’ve never put the corn flakes on top!! can’t wait to try this!
This is so simple! I love it!
This cheesy hashbrown casserole is some serious comfort food! My family loved it!
These are really yummy! I also like to do mine without the corn flakes.
