How Long to Cook Grilled Asparagus (Thick Spears) in the grill
Specification: 1 lb thick asparagus spears (pencil-plus diameter), woody ends snapped off, tossed in a thin coat of neutral oil and salt
3-Step Execution Protocol
Preheat grill to Medium-high direct, 450°F (232°C), grate cleaned and oiled. Clean and oil grates. Prepare grilled asparagus (thick spears) (1 lb thick asparagus spears (pencil-plus diameter), woody ends snapped off, tossed in a thin coat of neutral oil and salt).
Cook for 5–8 mins (roll a quarter-turn every 90 seconds, laid perpendicular to the bars so they do not fall through). Flip at the 2-minute mark for even browning.
Spears are bright green with light char blisters on all sides, and a spear held horizontally by one end bends into a gentle arc without snapping — a straight spear is undercooked, a floppy spear is overcooked. Rest for 0 minutes before serving.
No internal temperature target — asparagus is judged by the bend test and colour, so internalTempTargetF is omitted per HR-2, matching the corn and mushroom conventions in this dataset.
