Rub olive oil all over the potatoes then sprinkle generously with Kosher salt.
Place prepared potatoes on baking sheet and bake for 1 hour.
Notes
Piercing the potatoes allows extra steam to escape.
I wouldn't recommend wrapping potatoes in foil before baking unless you like wet, soggy potato skins. Wrapping them with foil essentially steams the potato as it bakes because it traps the moisture in.
Garnish baked potatoes with your favorite toppings. Some popular versions include sour cream, butter, and chives as well as cheddar cheese, broccoli, bacon bits, chili, or diced jalapenos. You can also add shredded pork, chicken, or beef on top. The options are endless!
