Asparagus in the air fryer
Asparagus takes 5 to 8 minutes at 365°F (185°C) in an air fryer, shaken or turned at 4 minutes.
What to know about air frying asparagus
Cosori lists whole spears at 365°F for 5 to 8 minutes — the lowest temperature of any vegetable on its chart. That is deliberate: asparagus tips are far more delicate than the stems, and at 425°F the tips are ash before the stems are tender. The lower heat lets the whole spear catch up with itself. Thick spears take the top of the range, pencil-thin sprue can be done in four.
The mistake people make
Cutting the woody ends off with a knife at a fixed point. Where the spear turns woody varies from stalk to stalk, so a straight cut leaves some tough and wastes the good part of others. Bend each spear until it snaps and it breaks exactly where the woodiness ends.
How to tell when it's done
Bright green turning olive at the tips, with a spear that bends under its own weight when lifted from the middle but does not flop. Still-rigid spears are undercooked; limp grey ones have gone.

How long does asparagus take in an air fryer?
5 to 8 minutes at 365°F, shaking or turning at 4 minutes. That figure comes from Cosori. Cook times shift with the size and power of your machine, so treat the lower end as the point to start checking.
What temperature should I air fry asparagus at?
365°F, or about 185°C. That sits inside the 350–400°F band the USDA describes as typical for air frying.
Can you air fry asparagus?
Yes. Use a light spray of oil. Keep it to a single layer — crowding the basket blocks the air circulation the machine depends on, which the USDA specifically warns about. Preheat the machine first.
