What do I need to get started?

  • Yukon Gold Potatoes. I prefer these over russet potatoes for this. The Yukon Golds produce a super dense and creamy. If you don’t want to bother with peeling the potatoes, use Red Potatoes.
  • Chicken stock. I always cook my mashed potatoes in chicken stock over water. It adds a little something special to the flavor.
  • Salted butter. If you don’t use salted, be sure to add extra salt.
  • Heavy cream.
  • Mayonnaise. I know how it sounds, but this homestyle ingredient lends a richness to these potatoes.
  • Salt and pepper. A lot of it – you can season these however much or little you want.

How to make Slow Cooker Mashed Potatoes

Start by peeling the potatoes and dicing them into one inch cubes. They will cook more evenly and quicker this way. Add the potato cubes to the slow cooker.

Pour the chicken stock over the potatoes and add one stick of butter.

Cover and cook on high for 4-5 hours, or until the potatoes are fork tender. Once the potatoes are cooked, drain them and then add them back to the slow cooker.

Mash with a potato masher until you’ve reached your desired consistency. I prefer super smooth mashed potatoes, but you can make these chunky if you prefer.

Add in the heavy cream, mayonnaise, other stick of butter, salt, and pepper. Keep mixing with the potato masher until they’ve reached your preference.

Set the slow cooker to warm so everyone can come back for seconds and serve with a pat of butter.

Storage and Freezing

Leftovers can be stored in the fridge in an airtight container for up to 3 days. Reheat in the microwave with some butter.

I do not recommend freezing the mashed potatoes. All the dairy doesn’t make it very freezable.

Tips and Tricks

  1. Choose the right potatoes: Opt for starchy potatoes like Russets or Yukon Golds, as they yield the creamiest texture when mashed.
  2. Cut potatoes evenly: To ensure even cooking, cut the potatoes into uniform-sized chunks before adding them to the crockpot.
  3. Don’t overfill the crockpot: Fill the crockpot no more than two-thirds full to allow enough space for the potatoes to cook evenly and prevent overflow.
  4. Use chicken or vegetable broth: For extra flavor, cook the potatoes in broth instead of water. This will infuse the potatoes with savory goodness.
  5. Mash with care: Once the potatoes are cooked, mash them directly in the crockpot using a potato masher or handheld mixer. Be careful not to overmix, as this can result in gummy mashed potatoes.
  6. Adjust consistency: If the mashed potatoes are too thick, add a splash of milk or broth to reach your desired consistency. If they’re too thin, continue cooking with the lid off to allow excess moisture to evaporate.
  7. Keep warm setting: If you’re not serving the mashed potatoes immediately, switch the crockpot to the “keep warm” setting to prevent them from drying out.
  8. Garnish before serving: Sprinkle chopped herbs, grated cheese, or crispy bacon on top of the mashed potatoes for added flavor and visual appeal.
