Work smarter, not harder, this holiday season. Preparing dishes in your slow cooker can be a lifesaver, especially when the oven and stovetop are all spoken for. And when it comes to mashed potatoes, they come out wonderful when made in the slow cooker.

These mashed potatoes are creamy. They’re a dream. They’re smooth and delicious as if they have been whipped to perfection. Cover them in gravy for the perfect side. Or eat them as is.

Cover and cook on the high setting for 4 hours or on the low setting for 8 hours, until the potatoes are tender.

Open the lid. The potatoes should be tender at this stage and slightly brown. You’ll notice a lot of water. Do not fret; mash the potatoes with a fine potato masher until mashed and creamy. You can also use an electric mixer to beat the potatoes until whipped and smooth. The potatoes will thicken while mashing.

Storing leftover Crock Pot Mashed Potatoes

Refrigerate leftover mashed potatoes in an airtight container in the refrigerator for 3-5 days.

Prepare your dish ahead of time

Time is precious during the few hours we have to prepare our holiday dishes, so if you are making these delicious creamy mashed potatoes in a slow cooker this year, planning this dish could save some time and headache.

Peel and cube your potatoes the day before. Keep them covered in a bowl of water in the fridge until you’re ready to use them.

You can even par-boil cubed potatoes the day before and keep them in an airtight container in the fridge before returning them to the crock pot the next day. This might be a good option if you are short on time.

What do you serve them with?

Mashed potatoes are a great everyday side dish, but these are also impressive enough to serve at larger gatherings and throughout the holidays. Try them with:

Creamy slow cooker mashed potato FAQs

What are the best Potatoes for mashing?

The two most popular potatoes perfect for mashing are russet potatoes and Yukon gold potatoes. Both are starchy, which makes for a light and fluffy mashed potato. If you’ve chosen a waxy potato, chances are your mash will have some lumps in it. Some people prefer that, though.

How do you keep mashed potatoes from drying out in a crock pot?

Before placing your potatoes in the crock pot, greasing the bowl beforehand will help to prevent any burning or sticking that could dry out your potatoes. Leaving your mashed potatoes in a crock pot for a few hours may cause them to start browning on the edges. To prevent this, stir the potatoes often, and keep a few pats of butter on top to keep them moist. Leaving the lid on will greatly reduce dryness as well.

Why so much liquid?

This recipe calls for more liquid than most slow-cooker potato recipes. The extra liquid makes these potatoes extra creamy as the potatoes absorb the excess liquid. I do the same with my pressure-cooker mashed potatoes.

To halve the recipe

To halve this recipe to 8 servings rather than 16, cut the ingredients in half and cook in a 4-quart slow cooker on high for 4 hours or low for 7-8 hours.

Notes:

  • Feel free to leave the skin on the potatoes if you prefer. 
  • The potatoes will have a lot of liquid in the slow cooker when you take the lid off; this is expected. Immediately mash the potatoes. The potatoes will soak up the excess liquid. 
  • Keep the mashed potatoes in a warm setting until ready to serve.
