Kiawe wood chips in a foil pouch on a gas grill burner

Smoking with Kiawe on a Gas Grill

The rig most people actually own, and the one most barbecue writing pretends doesn't exist.

Roughly six in ten American households with a grill have a gas grill, and almost every word written about wood smoke assumes they own something else. That is a strange gap, because a gas grill smokes perfectly well. It just needs one thing added and one habit broken.

The thing to add is a smoke source, since propane produces heat and no flavor. The habit to break is cooking over lit burners. Almost everything worth doing with kiawe on gas happens on the side of the grill where the burners are off.

What to Burn

Kiawe Chips in a smoke tube, or a Kiawe Chunk wrapped in foil (poke holes) on the burner.

Gas gives you control; the chips give you the island. Keep the lid closed - every peek costs smoke.

The foil pouch, in detail

Two big handfuls of kiawe chips go in a double layer of heavy foil, folded into a flat packet roughly the size of a paperback. Poke six or eight holes in the top only. Set it directly on the flavor bars or heat tent over a lit burner — not on the grate, and not on the unlit side, where it will never reach smoking temperature.

Give it eight to twelve minutes before the food goes on. When you see thin blue-grey smoke rather than thick white, the pouch is working. A pouch runs about 45 to 60 minutes; for a long cook, build three or four before you start and swap them as each dies.

A stainless smoker tube does the same job with less fuss and holds longer, and it is the better buy if you plan to do this often. Chips beat chunks on gas either way — a chunk needs sustained high heat to keep smouldering, and it tends to sulk and go out when the burner cycles.

Two zones, always

On a three-burner grill: light the left burner, run it as low as it will hold, put the pouch over it and the food on the right. On a four-burner, light the outside two and cook in the middle. Lid down, top vent open, and let the grill's own thermometer tell you what you have — most read 25 to 50 degrees high, so check it once against a probe on the grate and remember the offset.

Gas grills leak heat badly compared to a kamado or a pellet grill. On a cold or windy day you may not be able to hold 225°F at all. That is fine. Run at 275°F instead and accept a shorter cook — a slightly hot pit is a much smaller problem than opening the lid every ten minutes to fight it.

What goes wrong

  • Soaking the chips. Wet wood does not smoke, it steams, and then it smokes late and badly. The advice is everywhere and it is wrong. Use them dry.
  • Chasing thick white smoke. White billowing smoke is smouldering wood depositing soot and creosote. Thin blue is what you want, and it looks like almost nothing.
  • Pouch on the grate. It needs burner-level heat, not grate-level heat.
  • Lid up. Every look costs you five to ten minutes of recovery and all the smoke in the chamber.

Settings by Cook Style

What changes on a gas grill depending on what you are cooking.

Low & Slow

Light one burner, meat over the dead burners. Run a smoke tube of chips, or foil-wrap 2 kiawe chunks (holes poked) on the lit burner - chunks smolder about an hour each, half the refills.

Fuel load: A 12-inch smoke tube holds enough chips for 4-5 hours; refill for long cooks.

Roasting

Outer burners on, meat in the middle, tube smoking in a back corner.

Fuel load: One tube, lit at the start.

Hot & Fast

All burners high. Chips in a foil pouch, or better: one kiawe chunk wrapped in foil with holes poked, set right on a burner - it smolders about an hour.

Fuel load: One foil pouch of chips = ~30 min of smoke; one foil-wrapped chunk = ~1 hr.

Planking

Medium heat, soaked plank over a lit burner until it starts to crackle, then food on.

Fuel load: The plank is the smoke - chips optional.

Cold Smoke / Cure

One burner at its lowest, tube smoking, thermometer watching - gas runs hot, stay under 200F.

Fuel load: One tube, half-filled, relit as needed.
