Place scrubbed and quartered potatoes into a 6-quart slow cooker.
5 lbs Yukon Gold potatoes
Add chicken broth.
1 cup chicken broth
Add whole cloves of garlic.
4 cloves garlic
Cover slow cooker with lid and cook on high for 3-4 hours. Potatoes should be fork tender.
Do not drain broth from slow cooker. Add sour cream, cream cheese, and butter. Add salt and pepper to taste. Mash the potatoes with a vegetable masher. Stir and turn potatoes from the bottom of the crock, continue mashing until you reach your desired consistency.
I use Yukon Gold potatoes and I leave the skins on. There are lots of nutrients in the skins so why discard them? Once these potatoes are mashed up you can't even tell the skins are still in them because of how the slow cooker method softens them.
However, if you prefer your potatoes without the skins, you can absolutely peel them first and then proceed with the recipe. You can also use Russet potatoes or red potatoes instead of Yukon Gold.
These Crockpot mashed potatoes take about 3-4 hours to cook, so you can work on other things while they cook, and no "watched pot" syndrome!
