Foods & cuts · Spring onion

Spring onions

Three to four minutes whole. Among the fastest things on this list, and the one whose name changes most between territories.

What it is

Form: Whole vegetable
Typical weight: 10–20 g
Typical thickness: 8–15 mm
Cut: Not a cut of anything

Why it behaves as it does

North Dakota State gives three to four minutes for whole green onions. At that duration nothing about the interior matters — the cook is entirely surface char and wilt, and the failure mode is walking away. They are thin enough to fall through a standard grate, so they are usually laid across the bars rather than along them.

When is it done?

Food-safety endpoint

BBQHQ holds no food-safety rule for this food. We are not showing you another jurisdiction’s figure in its place — check your national food-safety authority.

Texture endpoint — how you actually know

Wilted and charred at the green end

The green has collapsed and blackened in places while the white is still firm. There is no interior to judge at this size.

How long it takes

Spring onions, grilled

Estimated cooking window

3 min–4 min

Low confidence

Why this is a range, not a number

Cookers hold temperature imperfectly
Individual animals and pieces differ

Cook to the endpoint, not to the clock. The window tells you when to start checking.

What this rests on

BBQHQ publishes a window for this cook.

Why confidence is not higher

At least one source does not state the cooker temperature.

How the sources were combined

ONE PUBLISHER, STATED AS A TOTAL. North Dakota State gives 3–4 minutes and no grill temperature, saying only that the time depends on the heat of the grill. BBQHQ publishes it as it stands and does not manufacture a second voice for it.

What makes the window as wide as it is

Cookers hold temperature imperfectly
Individual animals and pieces differ

When it goes wrong

Afterwards

Cooling, keeping and reheating what is left is general guidance for barbecue leftovers. Neither UK authority publishes anything specific to spring onions, and BBQHQ does not invent a distinction they do not make.
