Dry Rub for Pork Butt: The Recipe We Give Every Customer

Short answer: Mix ½ cup brown sugar, ¼ cup kosher salt, ¼ cup smoked paprika, 2 Tbsp coarse black pepper, 2 Tbsp garlic powder, 1 Tbsp onion powder, 1 Tbsp yellow mustard powder, 1 Tbsp chili powder, and 1 tsp cayenne. Apply to a bone-in pork butt 12-24 hours before the smoke, refrigerated. Cook at 225°F to 203°F internal — about 1.5 hours per pound.

This is the rub we send customers home with after they buy a Bull pellet smoker or a Coyote kamado. It has landed on hundreds of butts across our customers' patios, and it works. Sweet enough to build a bark, salty enough to draw moisture and set the crust, spicy enough to notice, not so hot that it ruins the leftovers on a sandwich the next day.

Nothing fancy. No exotic ingredients you have to source. The pantry version of every good BBQ competition rub, without the marketing markup.

The rub — full recipe

Makes about 1½ cups, enough for two 8-10 lb pork butts.

½ cup light brown sugar, packed

¼ cup Diamond Crystal kosher salt (if using Morton, use 3 Tbsp — Morton is finer and heavier by volume)

¼ cup smoked paprika

2 Tbsp coarse ground black pepper (16-mesh if you can find it)

2 Tbsp granulated garlic powder

1 Tbsp onion powder

1 Tbsp yellow mustard powder (Colman's)

1 Tbsp chili powder (Chimayo or ancho if you're picky)

1 tsp cayenne (2 tsp if you like more heat)

Optional: 1 tsp ground cumin, 1 tsp dried thyme

Whisk together in a bowl until uniform. Store in a sealed jar — stays good for 6 months on a cool shelf. Double the batch if you're feeding a crowd or planning back-to-back cooks.

What each spice actually does

Brown sugar: the caramelization component. Melts around 300°F and locks the bark. Skip it and you'll get pale rendered pork instead of that mahogany crust.

Kosher salt: draws moisture up to the surface, dissolves into it, then re-absorbs — that's a dry brine, and it's why the rub goes on hours before the smoke. Table salt is too fine and over-salts by volume; iodized salt tastes metallic under long cook.

Smoked paprika: the color driver plus a second layer of smoke flavor that reinforces what the wood is doing. Regular sweet paprika works but loses about half the depth.

Coarse black pepper: big grains crack under the heat and release oils slowly across the 10-hour cook. Fine pepper burns off in the first hour.

Mustard powder: the emulsifier. Helps the rub stick to the meat and adds a tangy background note that plays off the sweet.

Cayenne + chili powder: heat you can adjust. Bump either up for spicier bark; leave both at recipe levels for something a mixed-age table will eat happily.

How to apply the rub

There are two schools: rub-and-cook (apply, wait 15 minutes, smoke) and rub-and-brine (apply, refrigerate 12-24 hours, smoke). Both work. The overnight version delivers a slightly firmer bark and more even seasoning; the same-day version is faster and 90% as good.

Either way, the technique is the same. Pat the butt dry with paper towels. Coat the whole surface — top, bottom, sides — with a thin layer of yellow mustard as a binder (you won't taste it after the smoke). Sprinkle the rub on generously; press it into every crevice with your palm; wipe your hands and go over once more if the coverage looks thin. You're targeting a solid, opaque coating — not a light dusting.

Refrigerate uncovered on a wire rack for 12-24 hours if you have time. This gives the salt time to work and dries the surface — a dry surface takes on smoke faster than a wet one. Pull it out of the fridge 45 minutes before the smoke starts so it comes up toward room temp.

Smoker settings

Temperature: 225°F throughout. Some pitmasters bump to 250°F to shave 2 hours off the cook — that's fine, but pull earlier and rest longer to compensate.

Wood: post oak is the classic pairing for pork butt (traditional in Texas central BBQ). Pecan and apple are the runners-up — pecan for a rich, slightly sweet smoke; apple for the lightest, most beginner-friendly flavor. Avoid mesquite on pork butt — it's too aggressive for a 10-hour cook.

Cook time: plan 1.5 hours per pound of raw weight. An 8-lb butt is a 12-hour cook. Don't chase the clock — chase the internal temperature. Every butt hits its own stall (usually 165-170°F) and comes out of it on its own time.

Wrap or no wrap: at internal 165°F, some pitmasters wrap in butcher paper or foil to push through the stall faster. If you want maximum bark, don't wrap. If you want to shave 2-3 hours off the cook and don't care about the very outermost crust, wrap in foil with a splash of apple juice.

Pull temp: 203°F internal, probe-tender (the probe should slide in like room-temperature butter). Rest wrapped in a cooler for 1-2 hours minimum before pulling.

What we cook this on

The recipe works on any smoker that will hold 225°F for 12 hours. Our top recommendations from the smokers we sell:

Bull Blackhorn 24" Kamado — ceramic-walled, holds 225°F effortlessly on a single load of lump charcoal, doubles as a hot grill for the rest of the week. Best if you want one cooker that does BBQ + steak + pizza.

Coyote / Bull pellet smokers — digital temperature control, hopper-fed, wake up in the morning and check the probe on your phone. Best for beginners and for folks who don't want to babysit.

Offset stick burners — if you already know you love wrangling a fire, you don't need our advice. If you're new to smoking, don't start here.

After the cook

Pull the pork with two forks, gloved hands, or bear claws — whatever's clean. Toss with the reserved juices from the resting tray. Serve on brioche or potato buns, in tacos, over grits, on nachos, or straight off the cutting board with your fingers while nobody's looking.

Leftovers keep 4 days refrigerated and 3 months vacuum-sealed and frozen. Reheat gently in a foil packet at 275°F with a splash of apple cider vinegar — that's the trick that keeps it from drying out.
