Ensure there is a grated rack on the top level of your air fryer oven to prevent the seaweed sheet from floating up to the element and ensure air flow! Place a grated rack on the top rack, the other grated rack on the center rack and the solid tray on the bottom.
Line up your seaweed sheets, place a few drops of oil onto each. Either with a brush or your hands, spread the oil around the sheets.
Sprinkle the oiled seaweed sheets with salt.
Place one sheet on the center rack of the air fryer, and one on the bottom.
Air fry on the fries setting, 400 degrees for 4 minutes, rotating the sheets half way. Alternatively, you can cook one sheet at a time for 2 minutes on the center rack.
Cut into six rectangles with some scissors and enjoy!
