You can wrap them in foil. Didn't have any and I hate trying to unwrap them when they're hot. So we washed and stabbed 15 huge potatoes. I put them in the roaster at 350 degrees. But not for long enough. These were Monster Potatoes. For a crock pot (we had too many potatoes for ours), I think it was on low and they're ready by noon.
I fried some onions, and we had grated cheese, ham, onion, sour cream and butter on our potatoes. Yum!!!!
