Watch out for

• !Trim only the stem end, not both — the curved tip is fine to eat and helps anchor the bean to the basket grate.
• !Do not crowd. Stacked beans steam and stay limp.
• !If using haricots verts (thin French beans), reduce time to 6 minutes.

Do you need to preheat the air fryer for green beans?
