First, preheat the grill or oven to 450ºF.
Run potatoes under warm water and use a scrubby to remove any dirt or residue.
Drizzle potatoes with olive oil and use your hands to massage the oil into the skin. Then, generously season the entire potato with salt and pepper.
Individually wrap each potato in a piece of tin foil.
Grill: Place potatoes directly on the grill grates over direct heat. Cover, and let cook for 45-60 minutes.
Oven: Place potatoes directly on your oven racks and let cook for 45-60 minutes rotating after 30 minutes.
After 45 minutes, pierce one of the potatoes with a fork to see how tender they are. Once they are easily poked you know they are done!
Remove from heat, let sit for 15 minutes to cool, and then unwrap from foil to eat.
Top with your favorite toppings and enjoy!
