I don't remember where I first saw this idea at but I tried it and it worked like a charm! I had perfectly baked potatoes when I got home from work.
First wash your potatoes
Wrap in foil
I put some butter and garlic salt in the foil before I sealed it
Place in your crock pot and cook on high 4-6 hours or low 7-8 hours.
Carefully remove and serve!
They do look a little more brown than white but they taste just as good as oven baked potatoes
