Drain and rinse the beans, then pour onto a rimmed baking sheet, on top of paper towels. Place more paper towels on top (or use kitchen towels), and roll and pat at the same time. The skins will come off. Discard the skins.
Remove the paper towels and drizzle oil over the beans.
Sprinkle with sea salt and fresh cracked pepper.
Bake at 400 degrees for approximately 30 minutes or until crispy. Turn the oven off and allow to continue baking (stirring every 10 minutes) until they are the texture you like.
At the very end of baking, add any additional spices (sweet or savory).
Remove from the oven; allow to completely cool before eating!
