This Slow Cooker Garlic Mashed Potatoes recipe is such an easy way to make mashed potatoes! Delicious mashed potatoes recipe that can also be made ahead!
If you are anything like me, you love to cook all of the family favorites for holidays, celebrations and even for weeknight suppers. Yet, you are always looking for a way to make things just a little bit more streamlined, a little easier, just a little smarter. Well, let me tell you, this slow cooker recipe for making mashed potatoes is like hitting the jackpot in that department!
It not only frees up a portion of your stove from cooking the potatoes, it also frees up your time by letting you prep the ingredients, pour them into the slow cooker, set the timer and walk away! Then, a few hours later, you just add the rest of the ingredients, mash the potatoes and serve.
How simple is that?
How to Make Slow Cooker Mashed Potatoes
For this recipe, I do go ahead and peel my potatoes. If you’d rather not, take a look at my easy smashed potatoes recipe where you leave the skins intact. It’s a mighty delicious one, too!
For this one though, I highly recommend using russet potatoes. This recipe is for a crowd, so you’ll use five pounds.
Once you have your potatoes peeled, you cube them into 1-inch pieces and add them to the slow cooker.
And since this is a garlic mashed potatoes recipe, you will want to add in the garlic! If you’d prefer to omit the garlic, you certainly can at this step without any problems – they are still delicious!
Then, add in the salt, pepper, and one and a half cups of the milk.
Give it a quick stir to make sure it is well combined, pop on the lid and set the timer.
Once the potatoes are very tender, pour in the remainder of the milk.
Then, add in the butter and mash the potatoes until they are smooth and creamy. You can add optional toppings to your slow cooker garlic mashed potatoes or serve them plain.
If you are making your mashed potatoes to serve the same day, you can keep them on the warm setting in your slow cooker for up to two hours, stirring every hour. You may need to add more milk and/or butter to keep your potatoes’ consistency correct.
Make Ahead Mashed Potatoes
You can also transfer them into an airtight container and store in the refrigerator for up to a week and then reheat, transfer to a serving dish and serve. Isn’t that perfect for an easy make ahead side dish? I sure think so!

I made these garlic mashed potatoes last week. Wow! We gobbled them all down and wished we had more!
Thanks for a great recipe.
I’m so glad you liked them, Allyn! Thanks so much! xo
Cook HOW LONG?
Recipe says cook on high for four hours
Planning on making these for Thanksgiving!
Great mashed potato recipe! Would love to try this one of these days. Thanks for sharing.
Thanks so much! I hope you enjoy it! xo
Can you freeze the leftover mashed potatoes?
Just pre-made these for Thanksgiving! They are delicious! One thing I did was mix with a hand mixer after mashing, as the mashed potatoes came out a bit grainy with only the potato masher. Great recipe!
Wonderful to hear, Rachel! Thanks! xo
I just put this together in the crockpot. I added 8 oz cream cheese. Yummy!!!!
Has anyone tried freezing the potatoes?
I included the freezing instructions for mashed potatoes on my Easy Mashed Potatoes recipe. They would be the same for the Slow Cooker Garlic Mashed Potatoes. Hope this helps!
