Mashed potatoes have never been easier! Using a slow cooker removes the need to keep your stove on for hours at a time. The slow cooker softens these potatoes to perfection, giving you smooth, creamy mashed potatoes every time. The heavy cream helps to thicken the mashed potatoes and keeps them from drying out as they cook.

These potatoes are great for any occasion and are sure to be gone as soon as you put them on the table. Whether you need an easy side on a busy weeknight or to serve with our Grilled Flank Steak or a delicious potluck food, these slow cooker mashed potatoes have you covered.

Ingredients:

  • 4 pounds Yukon gold (yellow) potatoes, peeled and diced
  • 1 cup salted butter
  • 2 cups heavy whipping cream
  • 1 ½ teaspoon black pepper
  • 1 ½ teaspoon sea salt

Equipment You Will Need

You will want a slow cooker that can hold about six and a half quarts. This will give you enough space to cook and mash the potatoes without them spilling over as you mix them. You will want to have a metal potato masher on hand to mash your potatoes. To make your clean-up process easier, you can use a plastic liner in your slow cooker. You can also use a pressure cooker on the slow cooker setting.

How to Make Slow-Cooker Mashed Potatoes

  • Peel your potatoes and dice them into small pieces about ½ inch wide.
  • Place the diced potatoes in your slow cooker with the butter, heavy cream, salt, and pepper. Cook the potatoes on high until the potatoes are soft.
  • Use a metal potato masher to mash the potatoes until the mixture is creamy and mostly smooth. A few chunks of potato are okay.
  • Top with salt and pepper as desired, serve, and enjoy!

Serving Ideas For Mashed Potatoes

This side goes great with a wide variety of dishes. From grilled chicken to pork chops, this side is sure to be the superhero of your next meal. Try making a simple gravy to take your mashed potatoes to the next level.

How to Store Leftover Mashed Potatoes

Your leftover mashed potatoes can be stored in the fridge for up to a week in an airtight container. Alternatively, you can freeze your leftovers for up to 3 months. Frozen mashed potatoes should be thawed overnight in the fridge and then reheated on the stovetop with a little bit of heavy cream.

Frequently Asked Questions

How long can I keep my mashed potatoes in the slow cooker?

After mashing your potatoes, you can store them in the slow cooker on a warm setting for up to 4 hours. After that, you should transfer them to a different container. Leaving your mashed potatoes in the slow cooker for too long will cause some of the liquid to begin cooking off. To avoid dry potatoes, it is best to store your mashed potatoes in a separate container once they are fully mashed.

What is the best way to freeze mashed potatoes?

As we previously mentioned, freezing your mashed potatoes is a great option for long-term storage. To keep your mashed potatoes fresh, it is best to transfer the potatoes to an airtight, freezer-safe rubbermaid container. You can also put your mashed potatoes in a large freezer-safe Ziploc bag. If you are using a bag, be sure to squeeze all the air out to keep your mashed potatoes as fresh as possible.

What potatoes work best for mashed potatoes?

While russet potatoes are traditionally used for mashed potatoes, we recommend using Yukon gold or yellow potatoes. These hearty potatoes mash well once they have been cooked and will absorb any flavors you add. Their natural flavor compliments a wide array of dishes, making it a great choice for mashed potatoes.

Expert Tips and Tricks

  • Cutting your potatoes into smaller pieces helps them cook faster, which means you don’t have to run the slow cooker as long.
  • We like to use sea salt in this recipe, but any type of salt will get the job done.
  • If you like your mashed potatoes a little creamier, you can use an immersion blender to break up the remaining potato pieces.
