Why You’ll Love These Slow Cooker Mashed Potatoes
I boiled this slow cooker mashed potatoes recipe down (ha ha) to the essential reasons why it rocks:
Fastest prep ever — These crockpot mashed potatoes require, seriously, 7 minutes of preparation. All you have to do is cut up your potatoes (you don’t even have to peel them if you don’t want to!) and then let them cook for a few hours. When they’re done, you come back, dump the last few ingredients in, and whip those babies up in a matter of about 1 minute.
No peeling — This point deserves to stand out because peeling potatoes is a total bummer. No need for this recipe! You’ll get perfect, creamy slow cooker mashed potatoes every single time without peeling, boiling, or mashing! Just a whole lot of amazing mashed potato eating going on. Once you try these, you will never need another mashed potato recipe for as long as you live.
Red skin potatoes — I’m a sucker for those baby reds. So quick to cook up and so easy to whip together, they don’t taste gluey like other potato varieties will sometimes after they’re mashed. Plus, the skins are so thin, they whip right into this slow cooker mashed potatoes recipe, which helps with that whole not-having-to-peel thing.
Reheats well — If you’re lucky enough to have leftovers, all you have to do is microwave them to desired warmth, give them a stir, and be done! If they seem kind of dry add a tablespoon or two of milk to them before microwaving. Great for a side or a midnight snack.

Ingredients for Crockpot Mashed Potatoes
Red potatoes — These make ahead mashed potatoes in the slow cooker work best with red potatoes cut into 2 inch pieces. I don’t even peel them!
Sour cream — If you don’t have sour cream you can use plain Greek yogurt. Both taste great in this creamy mashed potatoes recipe, but sour cream will be a little tangier and creamier.
Milk — Any milk you have on hand is good for these, it helps to thin them out a bit and makes them easier to mix.
Minced garlic — I use jarred garlic in my easy mashed potatoes but you can mince your own or use those frozen, finely minced cubes they have in the freezer section now.
Salt & Pepper — I add these two to taste.
What to Serve With Slow Cooker Mashed Potatoes
How to Make Mashed Potatoes in the Slow Cooker
Wondering how to make mashed potatoes in a slow cooker? It couldn’t be easier, honestly. One trick though? Spray the inside of your slow cooker crock with cooking spray to make the clean up of this creamy mashed potatoes recipe that much easier.
- First, add the cut potatoes to the prepared crock, put the lid on it and cook on high for 2-3 hours or on low for 5-6 hours. (Or use the instant pot for even quicker results! Pressure cook on HIGH for 8 minutes with 1 cup of water, quick release, drain the water and proceed with the next step!)
- When the potatoes are done, add the sour cream, milk, garlic, salt, and pepper to the potatoes and use a hand mixer to blend together all ingredients.
- Taste and add salt and pepper as desired and SERVE.
Tips for the Creamiest Mashed Potatoes
Want the creamiest crockpot mashed potatoes recipe? Try adding butter when you add the sour cream, milk, garlic, and seasonings. How much is up to you. I start with about 4 tablespoons and go from there.
Another way to make these mashed potatoes in the crockpot the best they can be is to add cream cheese. I like to add about 8 ounces. For best results, let the cream cheese come up to room temperature before mixing.
Make Ahead and Storage Instructions
You can cook and mash this crockpot mashed potatoes recipe ahead of time and store them in an airtight container in the fridge until you’re ready to serve. Simply reheat in a pot on the stove and stir in some additional milk if you feel like they got too thick.
FAQs
This is obvious, but the best way to serve mashed potatoes is with a big scoop or two of gravy. Try my recipe for Easy Chicken Gravy for starters.
Not into gravy? These mashed potatoes are so good topped with some cheddar, Gruyere, parmesan, or any of your favorite cheeses.
What about bacon and some chives and a big dollop of sour cream? Yes, please!
Make them spicy by adding in chili powder, a can of diced green chilis, or chipotles in adobo. Taste as you go to make sure they aren’t too spicy.
Not sure how long to keep these slow cooker mashed potatoes cooking? Generally they cook for 3-4 hours on high or 6-8 on low. You’ll know they’re done when they are fork-tender and starting to fall apart. Once they reach that consistency, you can begin to mix in the other ingredients.
I swear by red potatoes but you can also use yukon gold, fingerling, or even russet if they are cut up into equal-size pieces before cooking to ensure even cooking. If you’re feeling crazy, you can mix up various potato types.
Expert Tips
- To keep your mashed potatoes from being too gluey, make sure you don’t over-mix them. That’s why I use a hand mixer, I feel like I can control the amount they’re whipped better. Stop when you still have a few lumps, those are supposed to be there. And please don’t use a food processor unless you need glue.
- I recommend cooking these slow cooker potatoes in a new(ish) crock pot. It has been my experience that older models don’t get hot enough to get these done in 3 hours. If you have an older model, then add another hour or so on to the cooking time.
- For the best-textured potatoes, add the sour cream and milk at room temperature. I have found that everything mixes together better if it’s all the same temperature. The dairy ingredients don’t have to be HOT per say but don’t pull them right out of the fridge and pop them into the slow cooker without letting the chill come off of them for a bit first.
- Store these holiday mashed potatoes in an airtight container in the fridge for up to 5 days. They’ll last about 10 months in the freezer. Thaw before reheating.

***RECIPE UPDATE*** A few readers have written in with a question about their potatoes tasting great but the consistency turning out “like glue” – I’ve never had this happen to my mashed potatoes but I did a little bit of research and found some information about how to avoid “gluey” potatoes. Click on the link for some tips for making perfect mashed potatoes.
***RECIPE UPDATE*** Some readers have reported that their potatoes were not nearly done cooking after 3-4 hours and not soft enough to mash at this point. After asking around and doing some digging, I’ve concluded that in most (if not all) of these instances, an older crockpot was being used (older than 2010-ish.). Newer crockpots should have no issue cooking the potatoes fully in about 3 hours.
Meshed potatoes are my favorite!
Awesome! I hope you enjoy this recipe 🙂
Great recipe!!! I love this blog and I am a regular viewer of the site. When I like any recipe I try to make it myself. Please keep it up to posting such great RECOPIES!

what do you think about cooking the potatoes and roast together in the slow cooker?
Then, remove the potatoes to another pot for the finishing touches.
For sure! You should check out my new pressure cooker version where this is done!

A word about the “gluey” potatoes…this usually happens when your cooked potatoes (mashed or not) are allowed to cool. You cannot do this. The complex starches will basically congeal and give you that “gluey” texture! You must keep them at a constant TEMPERATURE! For slow-cooker mashed potatoes, count back from when dinner will be served and make sure the crock-pot of potatoes is started.
Can the recipe be doubled by just cooking twice as long?
Nancy- because it’s a slow cooker, you shouldn’t have the double the cooking time! Just a little bit extra. Think of it as a pot of water.. depending on the amount in the pot will be how long it takes to get to boil. Less time if it’s shallow, more time if it’s a lot water. But once the water boils, it’s the same! Same with a slow cooker. Tack on a little extra for it to reach the appropriate temp, then the rest will be the same!
These are insane. I had never cooked mashed potato in a slow cooker before I read this post and now, I wont be turning back, they are the best!
looks interesting..gotta try this recipe!
These were AMAZING! This was my first time making potatoes this way so I was very attentive to the time they spent in the crock pot, and just as your notes said it took my new crock pot just over two hours for them to be perfect. I think next time I’ll take it a little easier on the sour cream (I eyeballed it and very possibly put too much 🤷🏻♀️).
My boyfriend said they were the best he’d ever had! I can’t wait to try more of your recipes !
I have for many,many years used can milk along with butter, to make my mashed potatoes, my family and friends loved them, my children has carried on this same tradition, my mother did the same recipe , for her many years, we really love these potatoes fixed this way, YOU must try them ONCE, you will hookdvfo life!!!!
Can you use any type of potato with this recipe?
