A dedicated offset smoker or pellet grill produces the deepest smoke ring and the most consistent bark on the finish pass — but neither is required for this recipe to succeed. A kettle grill or a standard two-burner gas grill set up for indirect cooking at 350°F delivers the same high-heat indirect environment with genuine wood smoke. Smoke penetration will be lighter than a dedicated smoker, but the texture, internal temperature, and structural outcome of the sous vide cook are entirely unaffected by which finishing device follows the bath.
This variation removes the equipment barrier for cooks who already own a grill and do not want to invest in a dedicated smoker to execute one recipe. The result is a finished chicken breast that reads as grilled-and-smoked rather than pit-smoked — a meaningful difference in smoke intensity, but not in quality or technique.
What changes for the indirect-grill finish?
On a kettle grill, bank a full chimney of lit coals entirely to one side of the coal grate. Place one fist-sized chunk of apple or cherry wood directly on top of the coals — not buried, not sealed in a foil pouch. A chunk placed directly on hot coals produces clean combustion smoke rather than the steam-and-smoke mixture that soaked wood chips generate; clean combustion delivers a higher proportion of the volatile aromatic compounds — guaiacol and syringol — responsible for characteristic smoke flavor.
Position the chicken breast on the grate opposite the coals, close the lid, and set the top vent directly over the chicken to draw smoke across the meat. This two-zone setup keeps the cooking side of the kettle at approximately 350°F while the smoke travels the full diameter of the grill before exiting.
On a gas grill, build a foil pouch from heavy-duty aluminum foil: add a handful of soaked wood chips, fold and crimp the pouch closed, and poke six to eight small holes in the top surface. Place the pouch directly on a lit burner. Leave the burners on the opposite side of the grill off, and cook the chicken breast exclusively on the unlit side with the lid down. Maintain 350°F measured at grate level on the cooking side. The smoke output from a foil pouch is lighter and shorter-lived than a wood chunk on open coals — which is why a dedicated smoker produces deeper penetration — but the foil-pouch method is sufficient for the approximately 15-minute finish window this recipe requires.
What stays the same as the original method?
The entire sous vide component — bath time, bath temperature, dry brine, and rub — is unchanged from the base recipe. The finish temperature target of 350°F and the finish duration are identical across all three finishing setups. The two-zone indirect principle is the same whether the cook is working on a kettle grill, a gas grill, or a dedicated smoker; only the smoke source and intensity differ.
When is the indirect-grill finish the better choice?
Choose this variation when you do not own a dedicated smoker, when weather or logistics make running a full smoker impractical, or when you are cooking a small batch of two to four breasts that does not justify firing a larger unit. This approach is also the right call for apartment patios, vacation rentals, and any setup where equipment access is limited but a standard kettle or propane grill is available.
