What is Boston Butt Pork Roast?
Boston butt roast comes from the upper shoulder of the hog. It’s a well-marbled, flavorful cut that contains a good amount of fat, making it ideal for roasting.
The name “Boston butt” originated in New England, where pork shoulders were packed into barrels called “butts” for storage and shipping. Despite the name, it’s not actually the rear end of the pig.
Benefits of Choosing Boston Butt
There are several reasons why Boston butt makes a great roast
- It’s very flavorful and juicy due to ample marbling.
- Abundant collagen breaks down into gelatin, keeping it tender.
- More affordable than premium cuts like loin or tenderloin.
- Low cost per serving when feeding a crowd.
- Versatile – shred for tacos, slice for sandwiches, dice for stews.
How to Choose the Right Size Roast
Boston butts are sold bone-in or boneless, ranging from 3 to 10+ pounds. Choose based on:
- Boneless is easier to carve. Estimate 1/3 pound per average serving.
- For a smallergathering, select a 3-5 pound roast.
- For a crowd, choose a larger 8-10 pound roast.
- Allow for leftovers – they make amazing sandwiches!
Ingredients & Equipment Needed
Ingredients:
- 1 boneless Boston butt pork roast (3-10 lbs)
- Olive oil or vegetable oil
- Dry rub – salt, pepper, spices like garlic powder, paprika, oregano
- Chicken broth or apple cider vinegar (for pan)
Equipment:
- Roasting pan with rack
- Instant-read meat thermometer
- Aluminum foil or parchment paper
- Large cutting board
- Carving knife
Step-by-Step Cooking Instructions
Follow these simple steps for roasted pork perfection:
1. Remove Roast from Packaging
Rinse roast under cold water and pat dry completely with paper towels. Trim off any excess hard fat.
2. Prepare the Roast
Coat all sides of the roast lightly with oil. This aids browning.
Make a dry rub with spices like salt, pepper, garlic powder, onion powder, paprika, oregano, etc. Apply the rub generously on all sides.
Gently cut small slits around the roast and insert slivers of garlic into the meat, if desired. The garlic infuses extra flavor as it roasts.
3. Preheat Oven to 325°F
Heating the oven while you prep allows it to fully preheat.Be sure to position racks in the center.
4. Sear the Roast (Optional)
For deeper flavor, sear the roast on all sides in a skillet with oil over high heat before roasting.
5. Place Roast on a Rack in a Pan
The rack elevates the roast to allow air circulation for even cooking. Add 1 cup broth or vinegar to the bottom of the pan.
6. Cover Pan Tightly with Foil
The foil helps retain moisture and promotes even cooking. Make sure the foil is sealed tightly.
7. Roast at 325°F for 4-6 Hours
Cooking times vary based on size. Estimate 1-1 1⁄2 hours per pound. Check at 4 hours.
8. Uncover and Roast for 1 Hour
Remove foil for the last hour to brown and crisp the exterior. Baste with pan juices.
9. Test Temperature & Check for Doneness
Use an instant-read thermometer to test the thickest part of the roast. It should register 200-205°F when done.
The roast should be very tender when poked with a fork. The bone (if any) should wiggle loose.
10. Remove from Oven & Let Rest 20 Minutes
The resting time allows juices to reabsorb for maximum tenderness and flavor.
11. Slice, Serve and Enjoy!
For carving, use a sharp knife to cut against the grain into slices or chunks. Serve with pan juices for added flavor.
How Long to Cook a Boston Butt Roast
- Boneless roast – Estimate 1-1 1⁄2 hours per pound at 325°F. A 5 lb. roast takes about 5-7 hours.
- Bone-in roast – Allow for additional cooking time since the bone conducts less heat. Figure 1 1⁄4 – 1 1⁄2 hours per pound at 325°F.
The roast is done when it reaches 200-205°F internally and the meat is fork tender. Always rely on a meat thermometer for doneness, not just cooking time.
What Internal Temperature Should the Roast Reach?
To ensure it’s safe to eat and falls apart tender, the Boston butt must reach an internal temperature of 200-205°F when finished cooking.
- At 160°F, the collagen begins breaking down.
- Between 185-203°F is ideal for maximum tenderness.
- Don’t go above 205°F or the meat may dry out.
Use an instant-read thermometer to check temp in the thickest section, without touching any bone.
How to Tell When the Roast is Done
Here are ways to check for doneness:
- Meat thermometer reads 200-205°F at thickest part.
- Fork inserted meets little resistance when twisting.
- Meat has visibly shrunk back from the ends of any bones.
- Bone moves freely when wiggled (if bone-in).
When done, the roast will be extremely tender and literally falling apart!
Let the Roast Rest Before Carving
After roasting, always let the pork rest for 20-30 minutes before slicing.
This resting period allows the juices to reabsorb back into the meat. If you skip this step, the pork will leak juices excessively when carved.
Tent loosely with foil to keep warm. The temperature will continue rising 5-10 degrees during resting.
Carving and Serving the Roast
To serve the pork roast:
- Place rested roast on a cutting board.
- Use a sharp carving knife to slice across the grain into 1⁄4-1⁄2 inch thick slices or chunks.
- Cut the roast into smaller sections if needed for easier slicing.
- Arrange slices on a platter and drizzle with pan juices.
Serve it with classic pairings like mashed potatoes, stuffing, roasted veggies, cornbread, coleslaw, applesauce, etc.
Leftovers hold up beautifully. Slice or shred for sandwiches, tacos, casseroles, soups, and more!

Tips for Maximizing Flavor and Tenderness
Follow these tips when cooking a boneless Boston butt roast:
-
Trim fat – Leave a thin layer for moisture. Too much fat can cause the meat to steam.
-
Apply a spice rub – Flavorful spice blends boost flavor and promote bark formation.
-
Brown the roast first – Quickly searing all sides adds deeper, richer taste.
-
Use a meat thermometer – It’s the only way to accurately determine doneness.
-
Cook low and slow – Low oven temps tenderize collagen and fats. Be patient!
-
Let roast rest before slicing – Resting allows juices to redistribute into the meat.
-
Slice across the grain – Cutting against the grain shortens tough muscle fibers.
-
Make use of leftovers – Shred, slice or dice leftovers for easy meals all week long.
As you can see, cooking a perfect boneless Boston butt pork roast is easy when you follow this simple process. Low, slow roasting at 325°F tenderizes the meat beautifully. Allow 1-1 1⁄2 hours per pound, and roast to an internal temperature of 200-205°F.
