Slow Cooker Cheesy Potatoes is an incredibly simple side dish that is perfect for a holiday meal but it’s easy enough to serve for a simple weeknight family dinner.

Crockpot Cheesy Potatoes

Since gooey cheese makes almost everything better, this cheesy potato side will probably be the most popular thing on the dinner table! The diced potatoes are smothered in a creamy cheese sauce made with cheddar cheese, sour cream, and cream of onion soup. 

Since it uses pre-made ingredients, you can make it even if you’re distracted or super busy, which is most likely the case around holiday dinners or even busy weeknights. 

I have a baked cheesy potato casserole (aka funeral potatoes) but this crockpot version leaves plenty of oven space for other things, or it’s helpful to prep before leaving for awhile. 

This, my friends, is why I love the slow cooker. You just add everything to it, and then let it cook the food for you. It’s your kitchen’s best friend! 

And that’s why my slow cooker recipes are some of my favorite ones!

Equipment you’ll need

Ingredients

Below is a list of the ingredients you’ll need to gather to make this recipe, why you need them, and possible substitutions. Scroll all the way down for the full recipe card with measurements.

  • Potatoes – Save yourself time and use a 2 lb bag of frozen diced potatoes. You do need to thaw them first so move them to the fridge the night before you need them, if you remember.
  • OnionI used white onion, but any variety will work.  
  • ButterUse unsalted butter so you can control how salty it is. Don’t forget cheese, and creamed soups usually contain a fair amount of salt as is.
  • Cream of Onion Soup – The condensed soup adds to the creaminess of this cheesy potato recipe and great flavor, but you can use cream of mushroom soup, celery, or cream of chicken
  • Sour CreamUse full-fat sour cream so that the sauce is extra tasty and robust. 
  • Garlic PowderThis rounds out all the flavors.   
  • Salt and Pepper – Can be adjusted as needed. 
  • Cheese – Cheddar cheese is sharp and melts easily. I always recommend shredding your own cheese off a block to prevent anti-caking agents

FAQs

What is in cheesy potatoes?

Cheesy potatoes are made with just 9 simple ingredients – potatoes, cheese, sour cream, “cream of” soup, onion, butter, and seasonings.

How do you make low-carb cheesy potatoes?

Use cauliflower instead of potatoes, like in my loaded cauliflower casserole. Cauliflower cooks faster than potatoes, so only cook them for about an hour or two. 

How long to cook cheesy potatoes in slow cooker

It will take about four hours for potatoes to get soft in a crock pot that is on HIGH. If they are diced into small pieces, it might only take 2-3 hours.

Why are my cheesy potatoes runny?

This is probably because you either used frozen hashbrowns before thawing them or you didn’t pat them dry with a paper towel after thawing them. When frozen potatoes thaw, they contain a lot of moisture, which would make the cheese sauce runnier.

What are the best potatoes to use?

I personally prefer diced potatoes for the texture, but you can use hashbrowns if you prefer.
If starting with raw potatoes, starchy Russet potatoes would be my pick.
