Rub potatoes in olive oil & sprinkle with kosher salt. (I lined my potatoes up on the foil drizzled olive oil on top of each one. With one had I rubbed the oil on the potato, with the other I sprinkled salt as I rotated the potato.
Wrap in foil & bake on low for 7-8 hours.
Split & top with your favorite toppings!
Notes
*Olive oil & salt are optional, but they make it taste so good!**You can stack your potatoes if you have a smaller slow cooker, but if you only have a large one & they are all on the bottom of the crockpot, check the potatoes's doneness at the 7 hour mark.
