I wanted to try making baked potatoes on the BGE for over a year, and I finally tried it. This is based on the directions by The Naked Whiz, a ceramic cooker expert.
You can go here to see the original recipe. http://www.nakedwhiz.com/bakedpotato.htm
I cut the salt down to one-half cup and scrubbed the potatoes to make sure all traces of dirt were removed from the skin. I used my own “universal rub” for meats instead of the Dizzy Pig rub.
And this made me think about creating a rub for baked potatoes. Something like onion and pepper and garlic – sounds almost like the rub I use for Santa Maria Style tri-tip.
I cooked an entire 5 pound sack of russet potatoes for this trial.
The original procedure said to turn the spuds half-way through the cooking time. I just let them bake on their own and did not turn them.
Naked Whiz says to bake the potatoes for one hour – My potatoes took one hour plus 10 minutes. If you try this, test for doneness using a skewer – it should easily push into the potato.
These were excellent – the texture is very good. The skin has a smoky flavor, which could be another area to play with – add hickory chips next time? More baked potato experiments are in order.
Here are some pictures. . .

Nice. I’ve wanted to do baked potatoes on the Egg ever since I got one, but for some reason or another I never do. Probably poor planning on my part. Maybe this week…
