I've been making my own recipe which is almost identical to this for years. It has excellent flavor and everyone always enjoys these. When in a hurry, I bake the potatoes at 450 degrees, turning after 10-15 mins. Depending on size, they can be on the table in under 30 mins. I also line my cookie sheet with nonstick foil and spray it to make turning the potatoes easier and to keep clean-up to nothing more than tossing the foil away.
