Why We Love Them

Mashed potatoes are always a great side dish, and go with almost everything. They require you to work quickly right at the busiest time of dinner prep though, mashing, mixing in additions, working with hot potatoes.

The CrockPot or slow cooker takes all of the work out of them. You can mash them once they’re softened and keep warm, saving so much time while finish up the meal.

How To Make Slow Cooker Mashed Potatoes

  1. Prep: prepare the potatoes by cutting them into 1″ chunks, as evenly as possible. Add them to a slow cooker with chicken broth.
  2. Cook: Slow cooker on high for 3 hours or low for 6 hours, or until potatoes are fork tender.
  3. Mash: Add the sour cream, butter, heavy cream, salt and pepper. Mash until no lumps remain.

Tips and Substitutions

  • We love leaving the skin on the potatoes, they add some great texture and flavor. You’re welcome to peel them first if you prefer.
  • If the potatoes are mashed too much, they will become gluey. A hand masher is the best way to ensure they don’t get overmashed.
  • We find russet potatoes work best for mashed potatoes. Yukon gold is another great option.
  • If doubling the recipe for a larger crowd, you may need to adjust the cooking time on the slow cooker.
  • Leftover mashed potatoes are great reheated, but have a bunch of other uses. They’re great in pierogi, and delicious turned into mashed potato cakes!

  • Herb and garlic cream cheese (trust me on this one)

Storing and Reheating Slow Cooker Mashed Potatoes

Mashed potatoes last 3-5 days in the fridge. Once they’re cooled, transfer them to a plastic bag or container.

Most potato dishes don’t freeze well, but mashed potatoes are the exception. Mashed potatoes freeze super nicely, as long as you have added the butter and cream.

Once cooled, place the mashed potatoes into a ziplock bag. Flatten the bag out, then freeze for up to 8 months.

To defrost, place the bag in the fridge, or cut a piece of the mashed potatoes off using a sharp knife.

To reheat slow cooker mashed potatoes:

  • Microwave: Add 1 tablespoon of cream or milk per cup. Reheat in 30 second intervals, stirring between each for even heating.
  • Oven: place mashed potatoes in a baking dish. Add 1 tablespoon of milk or cream per cup, and reheat for 10 minutes at 350°F, covered.
  • Stovetop: Place mashed potatoes with cream or milk into a pot, and heat, stirring constantly, for 5 minutes on medium heat.
  • Slow cooker: Reheat on high for 1 hour with 1 tablespoon of cream or milk per cup of mashed potatoes.
