Ingredients Equipment Method Notes

Ingredients
  

  • 1 lb asparagus woody ends removed
  • 1 tbsp olive oil
  • 1/2 tsp fine salt
  • 1/2 tsp black pepper
  • 1/2 lemon zested, plus more zest to finish

Equipment

  • Air fryer

Method
 

  1. Rinse the asparagus and dry it thoroughly with a towel; surface water prevents crisping.
  2. Toss with the oil, salt, pepper, and lemon zest.
  3. Lay the spears in a single layer with the tips pointing toward the centre of the basket. Cook at 400°F for 5 minutes, shake, then 2 to 3 minutes more. Thin spears finish near 6 to 7 minutes total, medium 7 to 8.
  4. Add a micro pinch of salt and a swipe of lemon zest while hot. Serve immediately.

Notes

1 tablespoon of oil per pound, maximum — more makes the spears floppy.
Tips toward the centre so they don't scorch against the basket rim.
Dry the spears — skipping it gives you soggy asparagus.
