How To Make Mashed Potatoes In Crockpot

We love these for Sunday dinners or busy weeknights, and especially for Thanksgiving. Some of our favorite side dishes to serve along with these potatoes are Green Bean Casserole and my Grandma's Famous Homemade Rolls.

Ingredients:

  • Water
  • Salted Butter

I like to use russet potatoes for this recipe. You can use new potatoes or Yukon gold potatoes instead, just make sure that you use 5 lbs. of potatoes.

As soon as potatoes are soft, mash them with a potato masher.

Add milk, butter, salt and pepper to taste. Taste as you go and add more milk until you get your desired consistency. 

Pro Tips:

  • Don't over-mash your potatoes. Mash until they are soft and creamy, then stop. 
  • You can add other mix-ins to these potatoes. Some of our favorite things to add are sour cream, cream cheese, garlic, chives, dill, or rosemary.

Can you warm mashed potatoes in a crock pot?

Yes! Whether you make them in the crock pot like in this recipe, or make them on the stove top and transfer them to keep them warm until dinner, the crockpot is a great vehicle to keep potatoes warm until ready to serve. 

How long can mashed potatoes stay warm in crock pot? 

You can make mashed potatoes the day before Thanksgiving and re-warm them with great success.

Once mashed potatoes are cooked, add an extra dose of milk and butter, so that the potatoes are kind of... soupy. This would not be ideal if you were eating them right away, but this will ensure that after being refrigerated, they will still be soft and creamy.

Put them in a deep casserole dish and store in the fridge overnight. Warm them up in the oven the next day, uncovered, with a little butter on top. 

Transfer the mashed potatoes back into the slow cooker, and set it to low. Do this for up to 4 hours, stirring once an hour. Stir before serving. The mashed potatoes will stay warm and creamy.
