This slow-smoked barbecue chicken is a masterclass in outdoor cooking, delivering exceptionally tender meat with a complex, smoky depth. The heart of this dairy-free dish lies in the aromatic dry rub, which combines dark brown sugar and warming spices with ground espresso beans to create a beautifully dark, savoury crust. By brining the bird first, you ensure the meat remains succulent throughout the long, slow smoking process on the grill.
Ideal for weekend entertaining or a relaxed family feast, this homemade barbecue classic is naturally gluten-free and dairy-free. Serving the chicken alongside a fresh slaw or charred corn on the cob provides a balanced, healthy meal that feels like a true celebration of summer. Whether you shred the meat for pulled chicken sandwiches or serve it in traditional quarters, the intense flavour profile is guaranteed to impress your guests.

How to make Slow-Smoked Barbecue Chicken
Back to contentsCombine all the ingredients except for the chicken in a resealable container, cover tightly, and shake well to combine. (Dry rub can be stored, covered, in a cool, dry place for up to 2 months.)
In a stockpot, bring 3.8L water and 240ml dry rub to a boil, stirring until the sugar and salt are dissolved. Let the brine cool to room temperature, then transfer to a nonreactive container and refrigerate until chilled. Add the chicken to the cold brine and refrigerate for 4 to 8 hours.
Set a wire rack on a baking sheet. Remove the chicken from the brine, pat dry with paper towels, and place on the wire rack. Discard the brine. Refrigerate for 6 hours.
Put the chicken on a rimmed baking sheet and coat the chicken lightly all over with 120ml dry rub (you may not need all of the rub) and set aside.
Remove any ash and debris if the smoker has been previously used and clean the grates. Fill a chimney starter about halfway with hardwood charcoal. Loosely crumple a couple of pieces of newspaper and drizzle or spray them with vegetable oil (this helps the paper burn longer and speeds up the charcoal-lighting process). Stuff the paper into the chimney's lower chamber place the chimney on the smoker's top grate, and light it. Let the charcoal burn until the coals are glowing red and coated in gray ash, about 15 minutes. Put on a pair of heavy-duty fireproof gloves and carefully dump the charcoal into one side of the grill—over the bottom air vent if your grill has one—leaving the other half free of coals. Place a disposable aluminum tray on the other side to use as a drip pan.
Place a few hardwood chunks or a foil packet of wood chips over the coals. Add the top grate and put your meat over the drip pan. Cover the grill, placing the air vents in the lid over the meat. Open both vents about halfway.
Place the chicken in the smoker and smoke, maintaining a smoker temperature of between 200° and 107°C, replenishing the wood chunks or chips as needed, until an instant-read thermometer inserted into the centre of a leg registers 74°C, 3 to 5 hours. Transfer the chicken to a cutting board and let rest for 10 minutes.
At this point, you can cut the chicken into quarters or tear the meat into shreds to make pulled chicken. Or, if you want extra-crispy skin, you can briefly roast the chicken in a 232°C oven, or prepare a grill with hot and cool sides, put the chicken over the cool side, cover the grill, and cook for 5 to 10 minutes.
