Slow Cooker Creamy Mashed Potatoes

Mashed potatoes are a staple for any holiday or Sunday dinner. With these slow cooker creamy mashed potatoes recipe you will get the most creamy, flavorful, buttery, and delicious mashed potatoes you’ve ever tasted. When cooking a big meal, it's nice to have some of your side dishes done ahead of time and keeping warm in the slow cooker.

I don’t know about you, but mashed potatoes are one of my favorite dishes for holiday dinner. Add a little gravy (try our How To Make Turkey Gravy From Scratch) and you’ve hit the jackpot. 

This recipe for creamy slow cooker mashed red potatoes might just be the talk of dinner. Creamy mashed potatoes with sour cream are probably not something many people would think to combine together, but you’ll change that with this delicious recipe. 

More perfect recipes for a holiday dinner would be our 30 Minute Dinner Rolls, Green Bean Casserole, Grandma’s Thanksgiving Stuffing, Sweet Potato Casserole and of course knowing How To Cook a Thanksgiving Turkey will come in handy. 

Trying to figure out how much to make without having too many leftovers, or worse, not enough, can be pretty difficult. When it comes to knowing how many pounds of potatoes you need to make mashed potatoes for the number of guests coming,
THIS is the best little calculator that we like to use.

What all do you need to make these crockpot mashed potatoes?

Mashed potato ingredients:

  1. Red potatoes
  2. Minced garlic
  3. Chicken bouillon cubes
  4. Sour cream (lite or fat-free is fine)
  5. Cream cheese (lite or fat-free is fine)
  6. Butter 
  7. Salt
  8. Pepper 
  9. White ground pepper (optional)

I love to sprinkle some white ground pepper (you can just get it at the grocery store on the spices aisle). It adds an incredible flavor to these (but a little bit goes a long way)!

If you want to add even more flavor to these delicious creamy mashed potatoes, you can try and make this Homemade Ranch Seasoning Mix and add 2-3 tablespoons to the mashed potato mixture.

Kitchen items needed to make this Thanksgiving potluck crockpot recipe:

  1. 6 or 8-quart crock pot (THIS is a great one!)
  2. Large pan
  3. Colander
  4. Two large mixing bowls
  5. Spatula
  6. Mixer or potato masher (hand or stand mixer work, the KitchenAid I definitely a favorite here) 



  • You can double the recipe, you will just want to make sure that you have a large enough slow cooker to accommodate all the potatoes! I would recommend an 8-quart slow cooker if you double the recipe.
  • The recipe calls for red potatoes, but you could also use russet potatoes and Yukon gold potatoes – they are all delicious.
  • The secret to the creaminess is the mix of sour cream and cream cheese.
  • The reason you keep it in the slow cooker is to let the flavors meld together – it makes the best-flavored potatoes!
  • If you have to travel, this is a dish that can travel easily (especially if you use a slow cooker that has one of those locking lids!).
  • If you want smooth mashed potatoes I would choose either the hand mixer or stand mixer since they can eliminate most of the lumps.  

How to make the creamiest slow cooker mashed potatoes

Put water in a large pot of and place it on the stove, add some salt and bring the water to a boil. Once the water is boiling add in the chunks of red potatoes, garlic, bouillon, and cook them until the potatoes are tender but still firm. 

It should only take the potatoes are about 15 minutes for them to get to the right consistency.

Then drain the water from the pot, but be sure to place the colander over another bowl to catch the water as we will need it later. 

In another large bowl, mash together the tender red potato chunks with sour cream and cream cheese with either a mixer or a potato masher. 

To get the type of consistency you want gradually add in the reserved water.


Once the mashed potatoes have reached the type of consistency you like, transfer the potato mixture to the slow cooker and cover it. Then, turn the crockpot on Low for 2 to 3 hours. Just before you are ready to eat the potatoes, stir in butter, salt, and pepper to taste. 

These are great to stay warm in your slow cooker until the rest of the meal is ready. Just keep on warm setting.

  1. Want to step this recipe up just a notch?!?! I make these same potatoes all the time (Just this Sunday, in fact, for company, with our prime rib roast). I add a half packet of dry ranch dressing mix!!! Just adds one more dimension of YUM!!! I have not put them in the crock pot, but will for sure be doing that step from now on when I am entertaining so I am not mashing the potatoes and giving away all my secrets to deliciousness, while my guests are all sitting around the kitchen watching (critiquing, eww...Why are you putting cream cheese in the potatoes?? Because they are AMAZING - that's why!!!! And, of course they agree once they eat them!
  2. It's just as easy to make mashed potatoes in the crock from start to finish, rather than using the pot only to warm and meld the flavors after fixing the potatoes on the stovetop. I cut mine into a medium dice, toss them into the crock with 1/4 cup of water, cook on high for three hours or so, and they are ready to mash. I've never added cream cheese, tho I often use sour cream, butter, and milk at this point, and let it all meld for however long it takes for supperime to arrive, lol, on low or warm. I can try adding the cream cheese and see what happens, as your combo here sounds lovely.
  3. I plan on trying this sometime this week. I hate having to whip up the mashed potatoes just as the turkey or ham is coming out of the oven to settle for its little rest before carving, because as you know that is when all the other side dishes are ready also, lol. So if these taste as good as they look they will become a new staple item in our busy household.
