Preheat air fryer to 400ºF. If your air fryer does not have a preheat button, simply turn it on 5 minutes before using.
Wash and dry 8 oz of fresh shishito peppers.
Cut a small slit in each pepper. You do this to allow the hot air to vent during the cooking process, otherwise they will explode open.
Place the shishito peppers in a bowl and add 1 tbsp olive oil, 1/8 tsp sea salt, and 1/8 tsp fresh ground pepper.
Mix until evenly coated.Place seasoned shishito peppers on an air fryer tray. Spread out so they don't overlap. Air fry at 400ºF for 7 minutes. Flip at the half way mark.
Shishito peppers will be ready when they are tender and slightly roasted.Remove from air fryer and place in a bowl. Serve and enjoy
