Want to make Rich & Creamy Slow Cooker Mashed Potatoes with sour cream and cream cheese?

Plan to make these incredibly rich and decadent slow cooker mashed potatoes for your next holiday meal! These are by far the most beloved of all of my mashed potato recipes. It’s a recipe that I found years and years ago and it’s remained the favourite for when we really want to indulge. When I say these are rich and creamy, I mean it. Hello decadent!

Sour cream and cream cheese truly make these the best Rich & Creamy Slow Cooker Mashed Potatoes you will ever make! Perfect for your holiday dinner!

Which Slow Cooker should I use to Make Rich & Creamy Slow Cooker Mashed Potatoes ?

For this recipe, we recommend a 6-8 quart oval shaped crockpot (slow cooker) such as the one pictured below. While this recipe will certainly work in other styles, this one affords the right amount of space for just the right amount of food. This is a large capacity crockpot at 8 quarts – if you are serious about slow cooking then this baby is affordable, has amazing reviews and is beautiful!

You can easily find this crockpot on Amazon here if you currently don’t own one and would like to purchase it.

Now, these slow cooker mashed potatoes are not the type that you cook IN the slow cooker. These are more of a life hack, you use your slow cooker to cook them a little it further with the sour cream and the cream cheese added, but mainly this type of slow cooked mashed potato is all about getting the cooking done beforehand. These rich, creamy slow cooker potatoes are good for holiday meals where you need to free up your stove top and your oven. It’s the same as making a pan of mashed potatoes the night before and reheating them the day of the holiday dinner. This way you have everything else free to cook the turkey or roast easily.

  • Using butter on the inside of the slow cooker makes the outside a little crisp and delicious! I love the browned milk and butter exterior that these can get! If you don’t like it, then don’t use butter on the slow cooker insert, just use cooking spray.
  • You could absolutely make these the night before, refrigerate them at the point where you place them in the slow cooker and then start them heating up the next day. I would add on an hour of cook time for a cold crockpot.

Happy cooking!
