Prep the air fryer: Preheat to 300°F (150°C) for 3 minutes. A moderate temp helps prevent scorching.

Cut the nori: Stack 2–3 sheets and use kitchen scissors to cut into rectangles, squares, or strips. Aim for bite-size pieces, about 2x3 inches.

Lightly oil: Place pieces shiny side down. Use a pastry brush to apply a thin film of sesame oil to the rough side. You only need a little—too much oil makes them bendy.

Season: Sprinkle with salt and your preferred seasoning. Go light, as flavors concentrate when crisp.

Load the basket: Arrange pieces in a single layer in the air fryer basket or on a perforated parchment sheet. Avoid overlap so they crisp evenly.

Air fry: Cook for 3–5 minutes at 300°F (150°C). Start checking at 2 1/2 minutes. They’re done when crisp and slightly darkened at the edges.

Cool to finish crisping: Transfer to a wire rack or plate. They’ll firm up as they cool. Taste and add a pinch more seasoning if needed.

Repeat: Continue with remaining pieces. If using multiple batches, keep finished snacks in a dry bowl or container with a paper towel.
