Baked Cheesy Potatoes

Who knew that 3 simple ingredients could come together in such a magical way?! If you’re planning your holiday menu, or even if you just need a new easy side dish for your next weeknight dinner, I hope that you’ll add this Cheesy Potato Casserole to your list! It’s a staple on our Christmas dinner table, and it seriously couldn’t be easier. Best of all, you can make the entire dish in advance and just bake it off when you’re ready to enjoy. We could all use simple, reliable, baked cheesy potatoes during a busy holiday season!

Ingredients

Since you only need 3 ingredients (plus salt and pepper) for this dish, it’s important to use the best, high-quality products available. Each ingredient plays a prominent role in creating the ultimate cheesy potatoes!

  • Potatoes: red potatoes are our top pick for this dish.
  • Cheddar cheese: extra sharp cheddar is our preference for maximum flavor, but you can substitute with a mild cheddar or even a combination of cheddar, American, mozzarella, Gruyere, Colby, or Pepper Jack. Use a block of cheese that you grate by hand.
  • Sour cream: thick, rich, full-fat sour cream. Don’t water down your casserole with low-fat varieties that lack flavor and texture.

The Potatoes

Red potatoes work particularly well in this dish because they keep their shape — giving the casserole that great shredded hash brown texture — but they also provide a creamy consistency. Red potatoes are low in starch and high in moisture, so they’re perfect when boiled. Other good options include white potatoes or russet potatoes.

How to Make Cheesy Potato Casserole

This make-ahead side dish comes together easily, but you’ll need to allow plenty of time to boil, cool and peel the potatoes. That’s the hardest part!

Process shot showing how to make cheesy potato casserole

  1. Boil potatoes for 10-15 minutes, or until fork-tender. Cool.
  2. Peel potatoes and shred with the large holes on a grater.
  3. Stir together grated potatoes, most of the cheese, and all of the sour cream. Season with salt and pepper, to taste.
  4. Transfer to a greased baking dish and top with remaining cheese.
  5. Bake in a 350° F oven uncovered for about 25 minutes, or until the cheese is melted and the potatoes are heated through.

What to Serve with Cheesy Shredded Potatoes

This rich, decadent and easy potato casserole is a simple side dish that pairs perfectly with just about any entrée! Here are a few ideas that go well with the cheesy potatoes:

Make Ahead Cheesy Potatoes

This casserole is the perfect stress-free option for a big holiday meal because you don’t have to worry about last-minute prep when you’re busy with everything else on the menu. Simply assemble the casserole as instructed, but do not bake. Cover and refrigerate the dish for up to 24 hours. When ready to bake, allow the dish to sit on the counter at room temperature for about 1 hour before baking in a 350° F oven for 25 minutes. If the dish is still cold when it goes into the oven, you will likely need to increase the baking time to make sure that the potatoes are completely warmed through.

Storage

If you have leftover potatoes, you can keep them in an airtight container in the refrigerator for 3-4 days. To reheat the potatoes, warm individual portions on a covered plate in the microwave. To reheat a larger dish of potatoes, cover and bake in a 350 degree F oven for about 20-25 minutes.

I do not recommend freezing these potatoes, as the sour cream may “break” when thawed and the potatoes may have a gummy, mushy texture.

Recipe Variations

  • Instead of sharp cheddar cheese, use a different good melting cheese (or a blend of cheeses). Nice options include Velveeta, Gruyere, Swiss, Colby, Colby Jack or Pepper Jack.
  • Instead of the red potatoes, try white potatoes, Russet potatoes or Yukon Gold potatoes.
  • Add Corn Flakes on top! To do so, toss together 1 cup of crushed Corn Flakes cereal with 1 tablespoon of melted butter. Sprinkle on top of the casserole before baking.

Tips for the Best Cheesy Potato Casserole Recipe

  • Don’t over-cook the potatoes. Keep an eye on them and boil them just until they’re fork-tender (this will typically take about 10-15 minutes, depending on the size of your potatoes). Overdone potatoes will have a wrinkly skin and the insides will appear gummy.
  • Make sure that your sour cream and cheese are at room temperature. This will help them combine with the potatoes.
  • I prefer to use cheddar cheese from a block that I grate by hand. It melts smoother into the potatoes.

  1. You had me at three ingredients! I can never resist potatoes, especially the cheesy kind. I just want to dig into that dish! I bet this would be so fun to jazz up too. Love the ease of this dish, which is just what I need for the holidays!

    1. Thanks, Gayle! You’re right — these could totally be jazzed up, but I still think that the simple original is the best! 🙂

  2. Hi, Marjie! I don’t care for sour cream on its own or as a garnish on dishes like tacos, but I love these potatoes. You might be pleasantly surprised! 🙂

    I have no idea if the Greek yogurt would work as a substitute. It would definitely change the taste and texture of the dish, but maybe that would still be okay for your tastebuds?

  3. Hi, Teresa! I agree — there are certain pre-shredded cheeses that don’t melt well. The Horizon cheese melts and works perfectly in this recipe!

  4. I always chuckle, whenever you post a recipe of your aunt “BEE’S”! Is her ‘real name’ “Beatrice”? If so, her nick-name should be spelled “BEA”, NOT “Bee” (as in bumble-bee!), unless she also raises bees which produce honey, and she’s known by that moniker locally, and also on numerous websites & blogs.

    1. Nope, her name isn’t Beatrice. Her real name is actually Blossom, but she has been known by her nickname, “Bee” her whole life. 🙂

    1. Hi, Lesli! No, I don’t recommend peeling before boiling. Peeled potatoes will absorb more water while boiling, which can result in watery, grainy potatoes (not a great texture, in other words). You want to preserve that starch in the potato. Plus, peeling after boiling is easier because they slide right off. 🙂

    1. Hi, Darlene! I don’t know. I worry that the cubed potatoes will not give it the same thick texture that it has with the shredded potatoes. It might work, it will just be different. Let me know if you give it a try! 🙂

    1. Hi, Melinda! Yes — I think that the Greek yogurt would work fine as a substitute for half of the sour cream. Enjoy!

  5. well I could not find the recipe that I wanted to do but I winged it I used onion and lots of different cheeses but added Frozen California Vegetable mix and can of cream of Chicken and then I saw this recipe …I was way off ,,wish me luck

    1. Hi, Melissa. I suppose you could, but it will give the dish a different flavor and texture, since the sour cream is much thicker (more like a Greek yogurt) and has a tangy texture. The sour cream also helps to hold everything together in a way that the heavy cream will not. I’m not sure of the measurements since I haven’t tried it myself. I would start with a small amount, and then stir everything together until it looks moist but not runny.
