Cut the potatoes into small bite-sized pieces, about ½” thick. Once all the potatoes are cut, use a clean towel to pat the potato pieces completely dry. You don’t want the potatoes to have any excess moisture.
Heat a 10 - 12 inch cast iron skillet over medium heat and add the oil. Let the pan and oil heat up for about 3 - 5 minutes. Place a piece of potato into the skillet and if it starts sizzling it’s ready.
Working in batches, add a handful of the cut potatoes into the hot skillet. Spread evenly so they all have space to cook. Do not overcrowd the skillet with too many potatoes.
Cook for about 7 minutes on the first side, then flip and cook for another 3 - 4 minutes or until the second side is golden brown and the potato is tender.
Remove the crispy potatoes from the pan and place onto a paper towel lined plate or baking sheet to drain the excess oil, and immediately hit with a pinch of salt.
Repeat with the remaining potatoes. This may be about 3 - 4 batches.
Notes
Don't overcrowd the pan with too many potatoes. If you do it will create steam and not get a crispy potato.
Do not cover the pan with a lid as this creates steam.
Keep the potatoes about ½” thick (not too small, but not too large) so that they will cook up crispy.
Please double check amounts when using the multiplying feature in the recipe card.
