When the asparagus are clean and ready, place them on a baking sheet or in the basket of your air fryer in a single layer. If necessary you can use a baking paper Spray with olive oil spray and put a good pinch of salt.

If necessary, preheat your air fryer to 375ºF (200ºC), pop in the asparagus for 8-10 minutes or until cooked.

Place on an extended platter and finish with lemon juice.
