Prep the potatoes by poking holes in the skin, (5 to 7 pokes), then coat each potato with shortening.
Poke the fork into the potato and hold it over your sink, then sprinkle garlic salt and oregano on all of the potato.
Place the potatoes on a baking sheet and bake for 60 minutes. Check doneness with a fork or paring knife. They should easily penetrate the flesh of the potato. If there is some resistance yet, bake for another 10 to 15 minutes.
Serve hot with toppings of your choice.
