Crock Pot Sour Cream and Chive Mashed Potatoes

Let your slow cooker do all the work this Thanksgiving with these fluffy Crock Pot Sour Cream and Chive Mashed Potatoes.

You can make these Sour Cream and Chive Mashed Potatoes in the slow cooker! It'll leave you plenty of space in the oven for a Thanksgiving turkey!

I know some families like to mix it up with their Thanksgiving menus. Maybe they have a different theme every year. Asian style this year. Appetizers and cocktails the next. Maybe they don’t even have turkey. Maybe some families have a Thanksgiving duck or Thanksgiving lasagna or Thanksgiving vegan butternut soup.

Some families like to have a culinary adventure on Thanksgiving, but my family isn’t one of them. I’ve tried to mix things up, but in the end, tradition always wins. And you know what? I’m okay with that.

Slow Cooker Sour Cream and Chive Mashed Potatoes--the perfect Thanksgiving side!

I’ll save my experimenting for all the other holidays. At Thanksgiving, I like the classics–the things we’ve come to love and expect around our table every November. Roast turkey and gravy. Sweet potato casserole. My sister-in-law’s deviled eggs. My Aunt Florence’s Butterhorns. Stove Top stuffing (don’t judge me! I have a strange love for boxed stuffing mix). Pecan Pie Bars. Custard Pie. And either mom’s cheesy party potatoes or classic, creamy mashed potatoes.

We always like to add a little sour cream to our mashed potatoes, so these Sour Cream and Chive Mashed Potatoes are nothing new around here. What is new is the way we made them. This year, we’re freeing up oven space by tossing our taters in the slow cooker and letting it work its magic. It only takes about four hours for the potatoes to cook down enough to mash them. Once the potatoes are soft, I add a generous amount of sour cream, milk, and butter then mash them into oblivion. Watching the potatoes slowly slurp up all the liquid is oddly entrancing.

Save a handful of chives and plenty of melted butter for the top, and you’ve got classic mashed potatoes without ever having to turn on the stove.

Make these Sour Cream and Chive Mashed Potatoes in the slow cooker!

When I make mashed potatoes, I always choose starchy Idaho® russet potatoes. They fall apart as they cook and soak up butter like a dream. No gumminess or heaviness here, just pillows of light, fluffy taters. Whether you’re a traditionalist or an adventurer, these Crock Pot Sour Cream and Chive Mashed Potatoes deserve a spot on your Thanksgiving table.

Crock Pot Sour Cream and Chive Mashed Potatoes

Prep Time 20 minsPrep Time
Cook Time 5 hoursCook Time
Total Time 5 hrs 20 mins Total Time
Serves 8


  • 5 pounds russet Idaho® potatoes, scrubbed and peeled
  • 3 cups milk, divided
  • 1 1/2 teaspoons salt, plus more to taste
  • Fresh ground black pepper
  • 1/2 cup butter
  • 1 - 1 1/2 cups sour cream
  • 1/4 cup chopped chives, plus more for serving.
  • Additional melted butter, for serving


  1. Spray the slow cooker insert with non stick cooking spray. Chop the potatoes into 1 inch pieces and add them to the crock pot. Sprinkle the salt evenly over the potatoes and add a good amount of pepper. Pour 1½ cups milk over everything. Cook on high for 4-5 hours or until potatoes mash easily with a fork. If you prefer, remove any browned crusty bits from the side of the slow cooker. Mash the potatoes with a potato masher or use a hand mixer to whip until you get the smoothness you desire.
  2. Warm the butter and additional 1 cup milk until the butter is melted and liquid is warm to the touch but not scalding. Slowly stir in the butter and milk, rotating with the sour cream. Use a potato masher to work the liquid into the potatoes. It will be soupy at first, but the potatoes will soak up the liquid as you mash them in. Add the last ½ cup of milk and sour cream if you want them to be creamier. Taste for seasonings and add more salt and pepper if needed. Stir in the chives. To serve, melt more butter over top and sprinkle with chives.

    Hmm. Boxed stuffing, huh? OK, when we dine together, I’ll bring the stuffing, you bring these awesome potatoes. 🙂

    Very smart making your mashed potatoes in the crock pot for Thanksgiving! I know my oven is on full gear as it is for TG. Love the sound of sour cream and chive!

  • Jennie | One Sweet Mess November 30, 2015, 4:50 PM

    These have to be the creamiest mashed potatoes I’ve ever laid eyes on. Yup, my family is all for traditional flavor combinations. Love these!

      My mashed potatoes were mush. What did I do wrong? I thought they turned out horrible,

  • Lori | Foxes Love Lemons December 7, 2015, 1:52 PM

    Yep, tradition ALWAYS wins in my house. Heck, the one year I made cornbread stuffing, not a single person touched it besides Jeff and I 🙁 The *only* thing I’ll jazz up is the mashed potatoes. Sour cream and chive? Who wouldn’t love these?

  • Lauren @ HealthyDelish December 14, 2015, 11:21 PM

    I’ve never made mashed potatoes in the crock pot. This is brilliant!

  • littleredkitchen December 22, 2015, 2:08 PM

    I can’t get over how smooth these potatoes look! I’ve never done mashed potatoes in the crockpot but you are convincing me right now to give it a try!

  • Betty December 20, 2016, 12:39 PM

    These potatos were horrible. Pure mush. Potato liquid

    • Courtney December 21, 2016, 12:23 PM

      Hi Betty- I’m really sorry to hear that. Were they gluey? Or just too much liquid? The mixture will look soupy when you first add the milk, but the potatoes should soak it up as you continue to work it in with the potato masher.
