Slow Cooker Mashed Potatoes

Are you ready for these make-ahead Crockpot Mashed Potatoes to become your favorite go-to potatoes?  You will never need to peel or boil potatoes again!

I have always been obsessed with potatoes.   From my Potatoes Au Gratin with Bacon to my Twice Baked Potatoes to my Roasted Potatoes with Bacon and Parmesan,  I could eat potatoes for every meal.

And my absolute favorite?  Company Mashed Potatoes!  Although in our home, our version of mashed potatoes were what we called “whipped” potatoes – potatoes whipped in my mom’s mixer to light and airy, fluffy perfection so each creamy spoonful melted in your mouth.  In fact, I never knew people actually “mashed” their potatoes until I was in my twenties.  And frankly, I never thought they were as good my mom’s “whipped” version.

Until now.

When I first saw the idea of slow cooker mashed potato recipes last year flooding Pinterest, I was intrigued but skeptical.  It just was too easy – no boiling, no peeling and wouldn’t the mixer scrape the slow cooker?  So, I finally decided to answer my own skepticism with the most palate pleasing potatoes yet.  These potatoes are so good, I was craving them up until they were gone – and after, which was probably like 3 sittings because I just couldn’t stop eating them!  sooooooooooo creamy….

Crockpot Mashed Potatoes Recipe

Not only are these Crockpot Mashed Potatoes potatoes crazy delicious, they are life changing!  As in they seriously changed my whole outlook, process, and frequency of making mashed potatoes.   Although I loved mashed potatoes as a kid, I hardly ever made them as an adult because I hated the tediousness of peeling the potatoes.  Peel no more.

To make these potatoes, you simply add all your potatoes – skin on – to your slow cooker along with some water, butter, garlic, spices, cook until tender, then mash with butter and sour cream.  How easy is that?

Now mashed potatoes don’t have to be just for special occasions like  ThanksgivingValentines Day,  but can be the easiest side to any weeknight dinner. 

Mega creamy, mega flavorful, mega easy make-ahead Slow Cooker Mashed Potatoes are about to become your favorite go-to mashed potatoes. You will never need to peel or boil potatoes again!

What Ingredients are in Crockpot Mashed Potatoes?

These Crockpot Mashed Potatoes are fabulously flavorful but still subtle enough you can douse them with your favorite gravy.

They are made with red potatoes, butter, milk, sour cream, water, garlic, salt, pepper, paprika, onion powder and my secret ingredient – pesto!  

The red potatoes have pleasant edible skin, but you can also use russet potatoes, but you will have to peel them first. 

The pesto infuses the potatoes with flavor without overwhelming them so once you mix them with some sour cream and milk, you not only have potatoes with the creamiest, most addicting texture but the flavor to go with it!

These mashed potatoes are so good, you will be shoveling bite after bite into your mouth while no one is looking – and then you won’t be able stop so you won’t care who is looking!

How to Make Crockpot Mashed Potatoes

Use a crockpot liner:  You will want to grease your slow cooker so the potatoes don’t stick to it, especially after they are mashed.  If want zero cleanup, then use a slow cooker liner. 

Wash potatoes:  We are leaving the skin on the potatoes, so make sure they are washed and scrubbed or else you will end up with gritty potatoes!

Cut potatoes uniform size:  Chop the potatoes into 1 1/2″ pieces.  Try and chop them roughly the the same size so they cook evenly.  Be aware that the smaller the potatoes, the faster they will cook.

Add butter and seasonings:  add butter, pesto, water, garlic and spices to slow cooker.  You can customize the seasonings to suit your personal preference.

Cook:  Cook on HIGH for 3-4 hours, or on LOW for 7-8 hours OR until potatoes are very tender. You want the potatoes to be very tender so they mash easily.  Your Slow Cooker Mashed Potatoes might require longer cooking time if you have an older crockpot or if you cut your potatoes into a larger size. 

Add milk:  Add milk and sour cream.  Make sure you warm your milk first so it incorporates easily into the potatoes which means less beating and less chance of gummy potatoes.  It also helps keep your potatoes warm while beating, which is also critical for fluffy potatoes. 

Mash potatoes: mash potatoes with a potato masher or beat with an electric mixer.  I highly recommend an electric mixer to make the process more efficient – its quicker, easier and creates much smoother potatoes.  If you prefer chunky potatoes, then you can certainly mash by hand, but an electric mixer eliminates the elbow grease.  No matter which method you use, don’t overwork potatoes or they might become gummy.

Season to taste:  Finally, taste your potatoes and add additional salt, pepper or other seasonings to taste.

Can I Add Parmesan?

Yes!  You can completely customize these Slow Cooker Mashed Potatoes.  After your potatoes are mashed, you can stir in about ½ cup freshly grated Parmesan.   You can also add different cheeses such as cheddar, blue cheese, etc. 

Can I Add fresh herbs?

Absolutely!  The pesto already adds a wonderful depth of flavor, so you will want to taste the Crockpot Mashed Potatoes before adding any additional herbs or spices.  I personally also love freshly chopped chives and bacon! 

Can I Use Greek Yogurt instead of Sour Cream?  

Yes!  Both sour cream and Greek yogurt and wonderfully creamy so I think it comes down to personal preference. 

How Do I make Creamy Crockpot Mashed Potatoes?

These Slow Cooker Mashed Potatoes emerge wonderfully creamy, but for even creamier mashed potatoes, you can stir in additional sour cream or swap the milk for heavy cream.  Also, mashing the potatoes more will make them creamier – just take care not to overmix.

Can I make Crockpot Mashed Potatoes in Advance?

Yes!  You can prepare your Crockpot Mashed potatoes completely ahead of time then keep warm on the WARM setting of your slow cooker for up to 4 hours, stirring occasionally and replacing the lid. 

How Do I reheat Crockpot Mashed Potatoes?

You can reheat mashed potatoes gently in the microwave, stovetop, oven or slow cooker.  over the stove, stirring occasionally or reheat the directly in your crockpot for about 2 hours on low.  

  • Microwave: Add mashed potatoes to a microwave safe dish. Cover and microwave for 2 minutes, then stir and continue to microwave stirring every 30 seconds until warmed through.  
  • Stovetop: Add mashed potatoes to a large pot and heat over medium heat, stirring occasionally.
  • Oven: Add potatoes to an oven proof baking dish.  Cover with foil and bake at 350°F for 30-40 minutes stirring occasionally and replacing foil.  Add additional 
  • Slow cooker: Add potatoes to the slow cooker and cook on low for approximately 2-3 hours, stirring occasionally.  Right before serving, add a generous dollop of sour cream and stir.  

Can I freeze Crockpot Mashed Potatoes?

Yes and no.  I personally am a mashed potato critic so I do not like frozen mashed potatoes.  Their texture changes when thawed and reheated and they become grainier.  If you are not a texture critic, or the mashed potatoes are going to be blanketed in gravy or sauce, then feel free to freeze them.  

If freezing mashed potatoes, don’t skimp on any of the butter and consider replacing the milk with heavy cream.  The extra fat will make the potatoes more freezer friendly.  You can even add additional butter than the recipe calls for for a better thawed result.

    Um, hello! These might change my life! I recently stopped peeling my potatoes before boiling, but I still have to cut them. This is brilliant! No peeling AND no cutting! And pesto? Totally doing that. Can’t wait to try these!

    • Jen says

      Yes, these are literally life changing!! I cannot wait for you to try them! I hope you love them Melissa!

  2. Melissa says

    OK. So it looks like there is a little cutting. But not the small cubes necessary for boiling 🙂

  3. Dorothy Dunton says

    Hi Jen! I haven’t peeled potatoes for years, I hand mash them with butter, cream or sour cream – smashed potatoes. Sometimes with herbs or cheese or bacon, whatever I feel like at the time! Why peel away the nutrients? They are quite addicting! PS Kevin is up and running again! 🙂

    • Jen says

      So happy to hear Kevin is up and running again – yay! Your version of potatoes sounds much like this one – so yummy and yes, completely addicting! 🙂

    These look so yummy. I will have to give it a try. I too hate peeling. So pretty much never make potatoes. Mmmm.

    • Jen says

      Hoe fully these will change all that Rachael! These are SO good and couldn’t be any easier!

  6. Layne says

    Potatoes is one thing Jesse misses in our marriage, haha! I finally decided to whip these up and holy cow- even I’m a fan (and I don’t like potatoes)! Haha. So easy and so good. Jesse’s parents (originally feom Idaho) said they were amazing and were impressed this was my first try of mashed potato making, Haha. Point is, these are goooood.

    • Jen says

      Sweeeet! I am honored I could make a fan out of a non-potato liker and even Idaho natives 🙂 Hope fully Jesse can enjoy more mashed potatoes from now on and you can enjoy an easy side! Thanks Layne!

  7. Kylie says

    Hi!

    I am not that big on pesto… Can you really taste the pesto? Can I use less pesto and still get the same texture and taste as if i used all 3 tablespoons?

    Thank you! – Kylie

    • Jen says

      Hi Kylie! Yes you can certainly use less pesto! I would start with 1 1/2 tablespoons to start and you can add more at the end if you want. Enjoy!

  8. Nicole says

    Hi! I saved a few of your recipes, and this is the first one I actually tried out. Mine didn’t turn out as pretty as the photo, kinda brown looking, but they tasted great, and so easy! I think maybe I’ll reduce the pesto a bit next time, but will definitely make again! Thank you!

    • Jen says

      You are so welcome! I’m so happy you enjoyed them! I hope you enjoy many more of my recipes!

  9. JOHN says

    Can one use an electric mixer in the crockpot with the liner therein?

  10. Shannon Falbo says

    Do you have a cooking estimate for peeled Russet potatoes?

    • Jen says

      I would chop into 1-inch chunks and cook on high for 4-5 hours.

  11. Kd June says

    Hi there, Would golden potatoes change recipe at all?

    • Jen says

      I think golden potatoes would also be great!
