Begin by preheating your air fryer to 400ºF. If your air fryer does not have a preheat setting, simply turn it on 5 minutes before using.
Cut your romaine in half.
Wash and dry thoroughly. You don't want your romaine lettuce to still be wet, it will not air fry as nicely. Brush 1 tsp of olive oil on your romaine lettuce. Distribute as evenly as possible.
Sprinkle with salt and pepper.
Place seasoned romaine lettuce in the preheated air fryer. Air fry at 400ºF for 3-5 minutes. Check at the 3 minute mark and give it more time if needed. The romaine will be ready when the outside leaves are slightly crispy. Don't overcook, the romaine will become too wilted.
When ready, remove from air fryer. Enjoy as is or add your favorite dressing and toppings!
