Slow Cooker Creamy Garlic Mashed Potatoes


With slow cooker season in full swing, what better to serve on a cold day than these Slow Cooker Creamy Garlic Mashed Potatoes? These are comfort food not only at it’s best but they’re also incredibly easy to make! These are a side you’ll definitely want to add to your Thanksgiving menu! They’re nearly guaranteed to be a crowd pleaser! My whole family loved them and I couldn’t get over their delicious garlic flavor. The garlic flavor resembles that of roasted garlic, you’ll notice in the photos below it appears as though it’s become roasted after so many hours of slow cooking.

These potatoes are perfectly hearty and creamy and it’s a forgiving recipe so you can make them just as your prefer. If you want to make them a little lighter you can use mostly milk and light sour cream. If you don’t like peels just peel the potatoes first or if you like some peels then peel half or use larger potatoes so there’s less peel to potato. And if you prefer your potatoes slightly chunky just don’t whip them very long. You can also adjust the garlic to suit your taste, a little more or less won’t hurt. Then of course, as with all mashed potatoes I recommend starting with less liquid then add more as you go until they are the consistency you prefer.

Now pass me a heaping bowl of these for dinner and that’s all I need, yum yum YUM. Try them soon! They’re the perfect easy side dish that everyone will love!

Slow Cooker Creamy Garlic Mashed Potatoes

5 from 2 votes

Yield: About 8 servings


  • 4 lbs red potatoes , cleaned (peeled or unpeeled), cut into 1 1/2-inch pieces
  • 1/2 cup water
  • 1 tsp salt , or to taste
  • 1/2 tsp , pepper, or to taste
  • 1 1/2 Tbsp minced garlic (4 cloves)
  • 1/4 cup butter , melted
  • 2/3 cup sour cream
  • 1/2 cup cream , warmed in the microwave
  • 1/2 cup milk , warmed in the microwave, or as desired
  • Minced chives and butter , for serving (optional)


  1. Spray a 6 - 7 quart slow cooker with non-stick spray. Place potatoes in slow cooker then pour water evenly over top (if your slow cooker allows excess moisture to evaporate from the slow cooker I'd recommend adding in an extra 1/4 cup of water). Toss with salt and pepper then add garlic and pour butter evenly over potatoes and garlic. Cover and cook on high heat 4 - 4 1/2 hours until potatoes are tender when pierced with a fork (don't drain!). Mash potatoes with a potato masher then add sour cream, heavy cream. Whip with an electric hand mixer until desired texture is reached, while adding in milk to reach desired consistency. Serve warm with more butter if desired and minced chives.

  • Michelle: These were amazing! I fell in love with the garlic mashed potatoes that come in a box but have eliminated processed foods from my pantry.

      • Hayley: Hello! If I need more servings can I just double everything? November 15, 2016 at 4:06pm Reply

  • Tami: Hi, just wondering about doubling this recipe? What do you think? November 20, 2015 at 7:05pm Reply

    • Jaclyn: I might recommend using two slow cookers (just borrowing one from a neighbor or friend) instead. I think a batch that large might cook unevenly. November 21, 2015 at 4:47pm Reply
