Make Cheesy Potato Casserole with fresh potatoes, sour cream, soup, green onions, & lots of cheddar cheese. Bake until golden and bubbly for an easy side.

Cheesy Potato Casserole may also be known as Cheesy Scalloped Potatoes, Cheesy Hash Browns, Funeral Potatoes, Mormon Potatoes, or Au Gratin Potatoes. Whatever you call it, they are a perfect side dish for any holiday like Easter, Thanksgiving, or Christmas.

Growing up, we ate them often for Family dinners on Sunday. If you only eat cheesy potato casserole on holidays, I highly encourage you to make them throughout the year! There’s no reason to deny yourself of this goodness! Seriously, do it!

Cheesy Potato Casserole Ingredients

Funeral Potatoes

As the name suggests, we’ll be using potatoes for this casserole. We’ll also be using cheddar cheese, sour cream, cream of chicken soup, green onions, and salt and pepper. An optional ingredient is butter, but I’ll talk more about that below.

What potatoes are best for a casserole?

When it comes to potatoes, almost any kind of potato will work for this recipe.

  • For a classic casserole, choose peeled russet potatoes for a fluffy thick texture.
  • To skip peeling, go for thin skinned potatoes like Yukon gold or red potatoes.
  • If you are short on time, use diced or shredded hash brown potatoes (30 oz) in place of boiling your own potatoes.

My dad taught me to make this dish using fresh potatoes. So, I have peeled a lot of potatoes in my lifetime. They can take more prep work, but the flavor is so worth it in my opinion. So, nine times out of ten, I use fresh potatoes.

What cheese is best for the casserole?

For the cheese, I don’t deviate from the classic, and I use cheddar cheese. I prefer to use either a mild or sharp cheddar cheese. While I love the flavor of extra sharp cheddar cheese, it can be drier. So, I tend to stick with either the mild or sharp varieties.

Additionally, for the creamiest potatoes, be sure to grate your own cheese. Prepackaged cheeses are often covered with starch that prevents the cheese from melting as well. Plus, the flavor is so much better if you grate it yourself.

I also like a LOT of cheese. So, I use more cheese than most recipes call for. Especially because I like to add an extra layer during the last 10-15 minutes of cooking. It gets all gooey and bubbly, and you are guaranteed to get cheese in every bite.

Do you add onion?

Get ready for a tangent: Have you ever seen that meme that goes, “Raisin cookies that look like chocolate chip cookies are the main reason I have trust issues.” Well, I feel the same way about Cheesy Potato Casserole. Unless, I know who made it, I have a hard time trusting it. One of the main reasons is onions.

If you’ve been read some of my other posts, you know I like the flavor of white and yellow onion. I really do. However, if there is even a hint of texture to the onion, I will gag when eating it. To me, the flavor of raw onion is way too sharp, and it completely overpowers the other flavors.

I’ve tried several cheesy potato casseroles that use white onion. To me, it seems the onion never gets fully tender. So, gagging inevitably happens. To compensate for this, my dad always uses onion powder in place of the raw onion. However, it seemed like something was always missing. It wasn’t until I tried my mother-in-laws’ potato casserole that I realized what it was.

My mother-in-law uses green onion in her casserole, and it is the perfect onion flavor without the gross raw texture. It’s such a simple swap, but she’s made the best cheesy potato casserole I’ve ever had.

So, the moral of that long story is, if you want a mild onion flavor, use onion powder. (That’s also a great option for kids who hate onion). Or, for a great onion flavor without the texture, use green onion.

Cheesy Potato Casserole Prep Tips

Cheesy Potato Casserole Process Shot

Because I like to use fresh potatoes, it does take more time to cook. To speed up baking time, I parboil the potatoes. This will significantly reduce the amount of time it takes to cook the casserole. Plus, potatoes need a lot of seasoning! By parboiling them, it allows more seasoning to get into the potatoes.

Growing up, there was a lot of argument in our house about the texture of the potatoes. We always diced them small. But my mom prefers a firmer potato, and my dad likes them more tender. Another thing I learned from my mother-in-law’s version, is that I like them more tender. So does my hubby.

So, for our perfect texture, I cut the potatoes in fairly large chunks. Then, I parboil them until a fork goes through the potato easily. Next, I roughly mash the potatoes with a potato masher. Mostly, I’m breaking up the large chunks of potato to keep some texture. But some of the potato will be more finely mashed which gives a creamier texture.

If you want a richer potato casserole, you can add butter as you mash the potato. Most of the time, I leave out this step. For me, the cheese, sour cream, and cream of chicken soup has enough richness, it doesn’t need butter. But, if you do add it, I will take the cheesy potato casserole over the top!

You can prepare this dish in advance and it will keep in the fridge for 2-3 days. When ready to eat, remove them from the fridge. Then, bake as directed in the recipe.
