Choosing the Right Roast

When selecting a pork sirloin roast to smoke, you’ll want to look for a few important qualities:

• Weight – Aim for a 3 to 5 pound roast, ideal for smoking.
• Appearance – Choose a roast that looks evenly shaped and trimmed of excess fat.
• Color – Opt for roasts that are pink to light brown rather than pale.
• Marbling – Look for decent marbling throughout for flavor and moisture.

Make sure the pork sirloin roast hasn’t been enhanced or injected with a salt solution, which can make it overly salty. Also avoid roasts with knots and hang tags, indicating it was frozen prior.

Prepping the Roast

Before smoking, the roast needs some simple prep:

• Rinse under cold water and pat completely dry with paper towels.
• Trim off any excess hard fat or sinew.
• Apply a dry rub all over the roast. Use your favorite pork rub or make your own blend of spices like brown sugar, chili powder, garlic powder, paprika and pepper.
• Refrigerate for at least 2-4 hours, preferably overnight. This allows the rub to really penetrate the meat for flavor.

Setting Up the Smoker

On smoking day, set up your smoker or grill for low and slow cooking with indirect heat:

• Maintain a steady temperature between 225-250°F.
• Use favorite wood chips or chunks like hickory, apple, cherry or pecan. Soak chips in water first if needed.
• Place a drip pan filled with water, juice, beer or a marinade under the roast if your smoker has the option. This provides moisture.
• Insert a digital meat thermometer into the thickest part of the roast, without touching bone. This lets you monitor the internal temp.

Once your smoker is up to temp, add your soaked wood for flavor and place the seasoned roast directly on the grate.

The Smoking Process

With the pork sirloin roast placed over indirect heat, close the smoker and let it work its magic:

• Smoke the roast for approximately 1 hour per pound, 5-6 hours for a 4 pound roast.
• Check periodically and spray with apple juice or cider if the outside seems dry.
• Monitor the internal temperature, until it reaches 140-145°F for ideal doneness.
• At about 150°F, brush with your favorite barbecue sauce if desired to glaze the outside.

The roast should develop a nice bark and pink smoke ring as it cooks low and slow to perfection.

Resting and Slicing the Roast

Once the pork sirloin roast reaches the target internal temp, remove it from the smoker and let it rest:

• Allow it to rest tented with foil for at least 15-30 minutes.
• This resting period allows the juices to redistribute evenly throughout the meat.
• After resting, the internal temperature will rise another 5-10 degrees.

To serve, neatly slice the roast across the grain into 1⁄4 to 1⁄2 inch thick pieces. Be sure to catch any juices to drizzle over the top.

• Buns – for pulled pork sandwiches
