The Best Casserole Potatoes

Over 10 years ago I married into a beautiful family full of homemakers and just overall crafty people. My mother-in-law is the quintessential of all mothers- She raised 8 children on a very modest budget, she made home cooked dinners each night for her large family and you better believe they were good.

Naturally, my husband expected these things out of his new wife… gulp.

First of all – no way in heck am I having 8 children. I settled on 4, still a stretch for me, but on some days I look like I know what I’m doing.

Secondly- My cooking skills at the time of our nuptials consisted of macaroni and cheese (the boxed kind), and pizza (the frozen kind).

This Cheesy Potatoes Recipe is downright delicious!

Luckily, my mother-in-law equipped me with a recipe box full of my husband’s favorite recipes. Cheesy Potato Casserole was on the top of his list.

I have made these casserole potatoes so many times over the past 10 years that I know it by heart. I have even made many variations of it, like these Zucchini and Potato Casserole and this Jalapeño Popper Potato Casserole.

Cheesy Hashbrown Casserole

Not only can you use freshly shredded potatoes, but I love to use frozen hashbrowns as a quick alternative. You can also use cubed potatoes or sliced potatoes. The options are endless!

This simple casserole recipe is perfect for any meal, but we usually have them at family gatherings, holidays, birthdays, weddings, baptisms, funerals, Sundays, you get the idea.

  • 1/4 cup salted butter
  • 4 green onions, chopped
  • 1 cup sour cream
  • 10 oz can cream of chicken soup
  • 2 cups sharp cheddar cheese, shredded
  • 6 cups frozen shredded potatoes, I usually use a whole 26oz-28oz bag
  • 1/2 cup salted butter, melted
  • 3 cups corn flakes, lightly crushed


  • Preheat oven to 350 degrees F.
  • Saute the green onions in 1/4 cup butter for about 3 minutes, until soft. Add the sour cream and soup and stir till combined and bubbly. Stir in the cheese until melted.
  • Remove from heat and add the shredded potatoes, stir to coat completely.
  • Pour into a lightly greased 9x13in casserole dish, set aside.
  • Add the crushed corn flakes with the 1/2 cup melted butter and stir to coat. Spread on top of the potatoes in an even layer.
  • Bake for 40-45 minutes or until center is hot and bubbly.
You can use freshly shredded potatoes in place of the frozen variety and reduce cooking time to 30 minutes.
If you want to freeze the casserole, do so before adding the corn flakes. Before baking add the topping and increase baking time till the center is hot and bubbly.
