How long to cook asparagus in an air fryer?
Air fry asparagus at 200°C (400°F) for 7–9 minutes, shaking once, until tender with lightly charred tips. Thin spears need 6–7 minutes; thick spears 9–11. Toss with oil and lay them in a single layer.
Air fryer asparagus is springtime in under ten minutes: tender, grassy spears with blistered, savoury tips. Trim the ends, give it a light coat of oil, and don't crowd the basket — that's all it takes.

How to air fry asparagus
- 1
Snap or trim off the woody ends of the asparagus.
- 2
Toss with a little oil, salt and pepper — and a grating of parmesan or lemon zest if you like.
- 3
Preheat the air fryer to 200°C (400°F) for 2 minutes.
- 4
Lay the spears in a single layer and air fry, shaking once, until tender-crisp with charred tips.
- 5
Finish with lemon juice, parmesan or a pinch of chilli flakes.
Pro tips
- Match spears by thickness so they cook evenly — thin and thick together will cook unevenly.
- The delicate tips char fast, so start checking a minute or two early.
- A single layer matters; piled-up spears steam instead of roasting.
