Step 1

If Using Only the Oven (see note): Preheat oven to 375°F (190°C). Using a fork or paring knife, puncture potatoes in several spots. Rub each potato with a light coat of oil. Arrange on a rack set on a baking sheet, or directly on an oven rack, and bake until a fork can easily be inserted into the center of each potato, about 1 hour. If setting potatoes directly on oven rack, set a sheet of foil on the rack below to catch any oil drips.

Step 2

If Using the Microwave and Oven (see note): Preheat oven to 450°F (230°C). Using a fork or paring knife, puncture potatoes in several spots. Microwave potatoes for 5 minutes. Rub each potato with a light coat of oil. Arrange on a rack set on a baking sheet, or directly on an oven rack, and bake until a fork can easily be inserted into the center of each potato, about 20 minutes. If setting potatoes directly on oven rack, set a sheet of foil on the rack below to catch any oil drips.

Step 3

Let potatoes rest 5 minutes. Slice each open lengthwise and scoop flesh into a mixing bowl. Add butter, season with salt and pepper, and roughly mash, just until butter is incorporated but potatoes are still chunky.

Step 4

Scoop mashed potatoes back into skins. (You can refill each skin, making 4 smaller potatoes, or use all the mashed potato to refill only half the skins, making 2 overstuffed potatoes.) Using your hands, reshape each stuffed potato back into a classic baked-potato shape.

Step 5

Top with toppings of your choice. To melt cheese, add it first, then return potatoes to oven until cheese melts, about 1 minute; alternatively, use a torch to melt cheese. Serve right away.
