How to Make It
Scrub potatoes and put in a 10- by 15-inch pan. Add oil and roll potatoes to coat them.
Bake on the bottom rack of a 350° oven for 20 minutes, then turn temperature to 400°. Continue baking until potatoes are very tender when pierced, about 30 minutes longer.
Serve whole or cut in half. Season to taste with salt and pepper.
