How to Smoke Pork Shoulder (Boston Butt) on the Big Green Egg

Learning how to smoke a Boston butt (pork shoulder) on the Big Green Egg is an essential skill for any backyard pitmaster. This classic low-and-slow method teaches fire management, temperature control, and patience while delivering some of the most flavorful barbecue you can make.

Despite its name, the Boston butt is not from the pig’s rear. It’s the upper portion of the pork shoulder. The terminology dates back to Colonial New England, when this cut was packed into large barrels called “butts” for transport and storage. The name stuck, even though the cut comes from the shoulder.

The Big Green Egg is ideal for this style of cooking. Its ceramic shell retains steady temperatures for long periods, and when combined with lump charcoal and hardwood smoke, it creates an excellent environment for tender pulled pork and a deep, well-developed bark.

When cooked correctly, a Boston butt develops a deep mahogany crust while staying moist and tender inside. This guide explains how to smoke a Boston butt on the Big Green Egg, covering setup, temperature targets, timing, and practical techniques to produce consistently great pulled pork.

Quick Answer: How Do You Smoke a Boston Butt on the Big Green Egg?

Set the Big Green Egg for indirect heat at 250°F using a convEGGtor. Generously season the Boston butt with your preferred BBQ rub and smoke until the internal temperature reaches about 165°F. At that point wrap the meat in foil or butcher paper and continue cooking until it becomes probe-tender at 200–204°F. Most butts take about 8–12 hours depending on size and fat content. Rest the meat for at least one hour before pulling to ensure juicy, tender pulled pork.

Tip: Times vary with size, marbling, and temperature consistency. Always use internal temperature and probe tenderness as your guide rather than relying solely on clock time.

Prepping the Boston Butt

For an 8–10 pound Boston butt, start by scoring the fat cap in a cross-hatch pattern about a half-inch deep. The small diamond cuts help the rub penetrate and increase the fat’s surface area so it renders and crisps more evenly. As the pork cooks, the scores open and allow smoke to reach the interior, helping create those prized caramelized edges often referred to as “burnt ends.”

Using a Binder

A binder helps the rub stick. I usually use a thin layer of yellow mustard; you won’t taste it after cooking but it acts like glue for the seasoning. If you prefer, substitute a light coating of olive oil or a bit of hot sauce for some background heat. The goal is simply to create a tacky surface so the salt and spices adhere and form a solid bark.

Seasoning the Boston Butt

Use a favorite BBQ rub and apply it generously—don’t be shy. Work the rub into the cross-hatch cuts and every seam so the seasoning clings to the surface. Pat the meat firmly to set the rub. Let the seasoned butt rest at room temperature while the Egg comes up to 250°F; this allows the rub to meld and the meat to lose its chill for more even cooking.

Setting up your Big Green Egg

Aim for a steady 250°F dome temperature for pulled pork. Fill the Egg with lump charcoal and tuck 3–4 chunks of hickory or your preferred hardwood into the coals for smoke. Wait until the thick white smoke clears and you see a clean, light grey “blue smoke”—that’s when to load the meat.

Place the Boston butt on the grate fat side down to shield the meat from direct heat. Then walk away—leave the lid closed for the first three hours to let the smoke penetrate and the bark begin to form.

Spritzing your Boston Butt

After the initial smoke period, start spritzing to build flavor and manage bark moisture. A simple spritz is a 50/50 mix of apple juice and apple cider vinegar with a few dashes of Worcestershire sauce and hot sauce. Mist the meat every 45–60 minutes—enough to rehydrate dry spots without soaking the bark. The spritz adds color, helps the rub set, and keeps the surface tacky so smoke continues to adhere.

Pull & Wrap the Boston Butt

When the internal temperature hits about 165°F and the bark is dark and set, pull the butt and wrap it. Wrapping—either in heavy-duty foil or butcher paper—helps you push through the stall and traps juices so the meat braises in its rendered fat. Before wrapping, give the meat one last spritz, then seal it tightly.

Return the wrapped butt to the Egg. You can slightly increase the temperature to around 275°F to speed the finish. Continue cooking until the meat is probe-tender and the internal temperature reaches about 200–204°F. Probe tenderness means the thermometer slides in and out with almost no resistance—think softened butter.

Pull and rest the Boston Butt

Once the meat reaches about 203°F and is probe-tender, remove it from the Egg. Crack the foil for 10–15 minutes to let steam escape—this prevents overcooking and helps maintain bark texture. Re-wrap the meat tightly and place it in a dry cooler (no ice) wrapped in towels for at least one hour, preferably two.

This rest period lets the juices redistribute and the collagen finish melting. When you unwrap the butt, the bone should slip out easily. Shred the meat by hand or with claws, mixing it with the accumulated juices for moist, flavorful pulled pork. Serve on buns, alongside classic sides, or use in tacos, bowls, and salads.

Enjoy the best pulled pork sandwiches you can make—deep bark, rich smoke, and juicy, tender meat that rewards the time and care you put into the cook.
