EDIT: I do wrap them in foil . . where I said “no foil” should have said “with or without foil”. The first time I did them in the oven, I didn’t use foil and I think they dried out a bit but I only had 2 potatoes in the crockpot. I did 8 potatoes once and didn’t use foil but rotated the potatoes a few times. Those didn’t need come out dry but when I’m doing only 2, I do wrap them in foil. Try it and see what works for you. Either way, they were edible and no one complained.
I’ve had a few questions about baking potatoes in the crockpot. I just recently started doing it and I love it.
(1) I had always wrapped my potatoes in foil and baked them in the oven. Never liked them in the microwave.
(2) I always seem short on oven space, even with two ovens.
(3) I think, though I’m not sure, that it uses less power to keep the potatoes in the crockpot for 6 or 8 hours rather than in the oven for 1-1/2 hours. Am I wrong?
Anyway, I wash the potatoes the night before (someone told me they need to be completely dry before putting them in the crockpot or they’ll get icky); let them dry overnight; wrap in foil, stick them in the crockpot on low for 6 or 8 hours and they’re perfect.
One of my goals is to use the crockpot more.
