Dump beans out onto a kitchen towel or a few layers of paper towels.
Pat beans dry. Be thorough - they need to be as dry as possible.
Heat 1/2" of oil in a Dutch oven to 325 F.
Working in batches, SLOWLY add the beans to the hot oil. The beans will most likely splatter, especially if they aren't very dry, so keep your face and hands back as you add them to the hot oil.
