Poke holes into the potatoes with a fork several times.
Rub the potatoes with olive oil.
Sprinkle the potatoes generously with salt and pepper. You really want that flavor to come out!
Wrap the potatoes in foil. (If you didn’t know, this traps the heat and makes sure the potato cooks evenly. Just make sure you’re cautiously pulling the potatoes out again since the foil and potatoes will be hot!)
Place the potatoes into the slow cooker, covering the crock with the lid.
Cook on high for 3-4 hours, or on low for 8-10 hours.
Remove the potatoes from the crockpot, carefully remove foil. Dress the potato with desired toppings.
Notes
Use any kind of potato for this recipe - larger ones may need more time to cook, and smaller ones may need slightly less time.
