Slow Cooker Garlic Buttermilk Mashed Potatoes

Creamy, buttery, and delicious Slow Cooker Garlic Buttermilk Mashed Potatoes are so heavenly!  This is what mashed potato dreams are made of! Slow Cooker Garlic Buttermilk Mashed Potatoes with #CrockPot For you mashed potatoes lovers… AND the lovers of slow cooking!

Depending on where you live and how you were raised, you’re probably very particular how you like your mashed potatoes.  I definitely am!  

Growing up in Idaho, where there were just as many potato farms as there were dairy farms, I think I can safely say I know my way around a few potatoes.  Although growing up, we always had mashed potatoes from a can… in powdered form.  Have no clue why our massive potato cellar was even FULL of those large Idaho potatoes.  Maybe for a cold day when the 10 gallon can of potato powder ran low?!?   

In my little world of potato land, I’m a huge fan of Red and Yukon Gold potatoes.  Put them together and it makes an amazing texture for mashed potatoes.  Put them in a slow cooker and you have super, SUPER creamy Slow Cooker Garlic Buttermilk Mashed Potatoes!

The best thing about these mashed potatoes… besides how they are just absolutely mind blowing, is that they are cooked in the slow cooker.  You can go about your day and come back hours later to whip them up.  

There’s also another best thing about the potato action being in the slow cooker.  AFTER you whip them, they can sit in there to stay warm until you’re ready for them!

I like to leave the trimmed skins on the potatoes.  One huge reason being, I peeled waaaayyyy too many Idaho potatoes as a child.  And… I’m just too impatient to peel them all.  Besides, it gives it a much better texture.

Put the trimmed and cut potatoes in your crock pot.  Along with a bushel of green onions and a whole bulb of crushed garlic.  

Place the lid on and set it to HIGH or LOW– depending upon what you’ve got planned that day.

The creaminess is already taking place!  Notice how buttery yellow the Yukon Golds are?

To test when the potatoes are just right, poke a fork in one potato to see if it is soft.  When the potatoes are tender , it’s time to put in the cream cheese and grated Parmesan cheese.  

For the last step, drizzle in the buttermilk as you use your favorite potato masher of some sort.  I like to plug in the handy hand held mixer and mash with the beaters.  

Once you see that you’ve hit all of the potatoes in the pot, get it to the consistency you prefer.  I like a little rougher texture with my mashed potatoes.  If you like it to the max creamy, pour a little bit more buttermilk in when mashing.

      Cindy, the crock pot action is definitely the only way to go. Especially when it comes to serving mashed potatoes for guests. I started doing it this way years ago for Thanksgiving, because it was a stress reliever knowing I didn’t have to be tied to the stove while my guests were arriving… and warm mashed potatoes are the best! 🙂

    We think totally alike when it comes to mashed potatoes! I love using yukon gold and red potatoes, and leaving the skins on so I don’t have to peel them. Plus, I like the texture that the skins give to the mashed potatoes. I cannot get over how incredible these look with the garlic, Parmesan, cream cheese, and buttermilk! The fact that they’re made in the slow cooker is just a bonus!

      Jen, you’re definitely going to love how easy it is. It’s less messy if I do them in the crock pot rather than on the stove… I always put the lid on the pan when cooking them on the stove and set the burner on HIGH. Then I get distracted and walk away. Until I hear the boiling starch of madness beginning to boil out of the pan and onto the stove… huge mess! 🙂

    I absolutely LOVE doing mashed potatoes in the slow cooker, it’s such a time saver!! I usually stick to my version, but I love the additions of the green onions and parmesan cheese in yours, so the next time I make some, I’ll be trying this out for sure 🙂 Pinned ♥
