Boston butt, also known as pork shoulder, is one of the best cuts of meat for slow-cooking on a grill. This cut is rich in marbling, making it perfect for low and slow cooking, which breaks down the connective tissue and renders the fat, resulting in juicy, tender, and flavorful meat. Whether you’re preparing pulled pork for sandwiches or serving sliced smoked pork, grilling a Boston butt can take your BBQ skills to the next level.
This guide will walk you through the entire process, from selecting the right cut to grilling and serving the perfect Boston butt. Get ready to impress your guests with a delicious smoked pork shoulder cooked right on your grill!
Choosing the Right Boston Butt
When selecting a Boston butt, you should consider the following factors:
Bone-In vs. Boneless
- Bone-in: Provides more flavor and retains moisture better.
- Boneless: Easier to carve and cook slightly faster but may require more careful handling to keep it intact.
Ideal Weight
- A 6-8 lb Boston butt is the best size for grilling. This ensures an even cook and makes it easier to manage on the grill.
Quality Matters
- Look for good marbling as this adds tenderness and flavor.
- Opt for fresh, not frozen cuts if possible.
- If available, heritage-breed pork (such as Berkshire) will have superior flavor and texture.

Preparing the Boston Butt
Trimming the Fat
- Some fat is necessary for flavor, but trimming excess fat (leaving about 1/4 inch) helps prevent flare-ups and promotes even cooking.
Seasoning & Marinade Options
- Dry rub: A well-balanced mix of salt, pepper, garlic powder, onion powder, paprika, and brown sugar enhances the flavor.
- Wet marinade: Combining apple cider vinegar, Worcestershire sauce, and a blend of spices can help tenderize the meat overnight.
- Resting time: Allow the rub or marinade to sit for at least 4 hours, preferably overnight, to let the flavors fully absorb.
Setting Up the Grill
Charcoal vs. Gas Grill
- Charcoal grill: Provides better smoky flavor but requires more heat management.
- Gas grill: Easier temperature control but needs wood chips for added smokiness.
Indirect Heat Setup
- Use a two-zone cooking method, keeping the heat source on one side and placing the meat on the opposite side.
- Maintain a consistent 225-250°F temperature for slow cooking.
- Add a water pan to keep moisture levels high.
Wood Chips for Smoke Flavor
- Best woods for smoking pork: Hickory, apple, cherry, or pecan.
- How to use: Soak the wood chips in water for 30 minutes, then place them in a smoker box or directly on hot coals.
Cooking the Boston Butt
Placing the Meat on the Grill
- Fat cap up or down?
- Placing the fat cap up allows it to render and baste the meat.
- Placing the fat cap down helps protect the meat from direct heat.
Temperature Control & Cooking Time
- Maintain a steady 225-250°F.
- Cook for approximately 1.5-2 hours per pound.
- Use a probe thermometer to monitor internal temperature without opening the lid too often.
Using a Meat Thermometer
- At 160°F, consider wrapping the butt in foil or butcher paper to retain moisture and speed up cooking.
- Continue cooking until the internal temperature reaches 195-205°F for fall-apart tenderness.
Resting and Serving
Resting the Meat
- Let the Boston butt rest for 30-60 minutes after removing it from the grill.
- This allows the juices to redistribute, ensuring a moist final product.
Shredding vs. Slicing
- Shredding: Use two forks or meat claws to pull apart the pork for sandwiches, tacos, or BBQ platters.
- Slicing: Cut against the grain for tender, flavorful slices.
Pairing with Sauces & Sides
- BBQ sauces: Vinegar-based (North Carolina style), mustard-based (South Carolina style), or classic tomato-based.
- Side dishes: Coleslaw, baked beans, cornbread, mac and cheese, or grilled vegetables complement the flavors.
Tips for the Best Grilled Boston Butt
- Keep grill temperature stable by adjusting vents and adding fuel as needed.
- Spritz with apple cider vinegar or apple juice every hour to keep the meat moist.
- Don’t rush the process—low and slow cooking ensures the best results.
- Avoid over-smoking by using wood chips sparingly.
- Let the fat render naturally—don’t trim too much before cooking.
