How to Smoke a Pork Butt

Updated November 2026 · 10 min read

Pork butt is the best first big cook on any smoker. It's affordable, loaded with fat and connective tissue, and very forgiving if your temperature drifts. This guide explains every decision, from the butcher counter to the final pull.

What a pork butt is (and what to buy)

Despite the name, pork butt comes from the upper shoulder of the pig. It's also sold as Boston butt or pork shoulder roast. The lower part of the shoulder is the picnic, which is leaner, has more skin, and is harder to pull evenly. For pulled pork, buy the butt.

• Bone-in vs. boneless: buy bone-in. It holds its shape better, and the bone slides out clean when it's done, which is a built-in doneness test.
• Size: most are 7–10 lb. Plan on about ⅓ lb of cooked meat per person. Pork butt loses roughly 40% of its weight during the cook, so an 8 lb butt feeds about 12–16 people.
• Look for good marbling and a fat cap that isn't excessively thick.

Trimming

Pork butt needs very little trimming. Your goals:

• Trim any thick, hard fat cap down to about ¼ inch. Hard fat won't render, and it blocks seasoning and bark.
• Cut off loose flaps and thin edges that would dry out or burn.
• Remove any bone fragments or glands (small gray lumps) you notice.

Seasoning and injecting

Binder (optional): a thin coat of yellow mustard or oil helps the rub stick. The mustard flavor cooks off completely.

Rub: season heavily on every side. A big cut needs a lot of seasoning. Use about ½–¾ cup for an 8 lb butt. Our All-Purpose BBQ Rub is built for this, or try one of the pork butt rubs.

When: you can season right before it goes on, or the night before. Seasoning it overnight, uncovered in the fridge, works like a dry brine and gives deeper seasoning and a better crust.

Injecting (optional): injecting a mix of apple juice, a little salt and sugar into the meat adds flavor and moisture deep inside. It's not required, since pork butt is naturally juicy, but it's popular in competitions.

Smoker setup and temperature

• Temperature: 225–275°F. 250°F is the sweet spot between bark, tenderness and time.
• Wood: hickory is the classic. Apple, cherry, pecan or oak are all great. A mix of hickory and a fruitwood is hard to beat. See our wood pairing guide.
• Fat side up or down? Put the fat facing your heat source. On most smokers where heat comes from below, that means fat side down, to shield the meat. On a pellet grill it matters less.
• Probe: place a leave-in probe in the thickest part, not touching the bone.
• Spritzing (optional): after about 3 hours, once the bark has started to set, spritz with apple juice or cider vinegar every hour if the surface looks dry.

The stall and wrapping

Somewhere around 150–170°F internal, the temperature will stop rising, sometimes for 3–5 hours. Evaporation from the surface is cooling the meat as fast as the smoker heats it. That's normal, so don't turn up the heat.

If you wrap, do it once the bark is dark mahogany and doesn't come off when you touch it, usually around 160–170°F. Adding a splash of apple juice inside a foil wrap is optional.

Knowing when it's done

Pulled pork is done at 195–205°F internal, but the real test is feel:

• A probe or skewer slides in and out with almost no resistance, like soft butter, in several spots.
• The bone wiggles freely and starts to pull away.

If it reads 200°F but still feels tight in places, give it more time. Pork is safe to eat from 145°F, but it isn't tender enough to pull until it's much hotter than that.

Not sure how long you'll need? The Smoke Time Calculator estimates it. Plan on roughly 1½–2 hours per pound at 250°F.

Resting, holding and pulling

• Rest at least 1 hour. Keep it wrapped, wrap it again in an old towel, and set it in an empty cooler. It will stay hot and safe (above 140°F) for 3–4 hours, which is your safety margin if it finishes early.
• Pull while it's still hot, using heat-resistant gloves or two forks. Slide out the bone, then shred, discarding large pieces of unrendered fat.
• Mix the bark through the meat so every bite gets some. Toss with the juices from the wrap and a sprinkle of extra rub.
• Serve sauce on the side so people can choose.

A sample timeline

For an 8 lb butt at 250°F, eating at 6:00 PM:

Starting this early looks extreme, but finishing early and holding the pork in a cooler is always better than serving late.

Common mistakes

1. Starting too late. Build in at least 2 hours of buffer.
2. Turning up the heat during the stall. Wait it out or wrap instead.
3. Pulling at a number instead of by feel. Probe tender is what counts.
4. Skipping the rest. Shredding it straight off the smoker lets the juices run out.
5. Under-seasoning. It's a big cut. Be generous.
