Once your peel your potatoes, you want to cut them into uniform pieces.  Not too big or too small.  Doing this will ensure that all of the potatoes cook the same.

Then, when the potatoes are done cooking you just mash them right in the crock.  You don’t even need to dirty another bowl! That’s a big win in my book!

The Best Potatoes for Mashed Potatoes

The best potatoes to make these easy crockpot mashed potatoes are russet potatoes.  The higher starch content ensures that they come out light and fluffy.  Using a waxier potato will make your mashed potatoes gummy.  I don’t know anyone that like gummy mashed potatoes.
