The best BBQ chicken breast recipe features a bold dry rub that marinates overnight in the fridge, then cooks using a direct-indirect heat method for smoky, tender, juicy chicken breasts finished with BBQ sauce.
Pull the chicken off the indirect heat at exactly 160°F on an instant-read thermometer inserted into the thickest part; carryover cooking during the 5-minute rest reliably brings it to the safe 165°F without drying it out.
Mix and apply the dry rub before coating with olive oil so the sugar and spices bond directly to the meat surface rather than sliding around in the fat.
The most common mistake is applying the BBQ sauce too early: sugar in both the rub and the sauce will burn over direct high heat, so hold the sauce until the final 2-3 minutes on the indirect side only.
If chicken breasts are thicker than 1 inch, pound them to an even thickness before rubbing so they cook through on the indirect side in the same time window without over-charring the exterior.
The rubbed chicken can be refrigerated for up to 24 hours before grilling; beyond that, the salt begins to cure the surface and can make the texture slightly firm. Leftovers keep refrigerated for up to 3 days and reheat well wrapped in foil at 325°F for 10 minutes.
