Grilling Tips for Pork Sirloin Roast

Follow these tips to ensure your grilled pork sirloin turns out perfectly:

Choose the right size – Pick a 2-3 lb roast for the most efficient grilling. Larger roasts may not cook evenly.
Trim the fat – Use a sharp knife to trim excess fat, leaving about 1/4 inch. This prevents flare-ups.
Bring to room temperature – Let the roast sit out for 30 minutes before grilling for more even cooking.
Use indirect heat – Grill the roast over indirect medium heat, not directly over the flames.
Use a meat thermometer – Insert a digital meat thermometer to check the internal temp, not just rely on time.
Allow resting time – Let the roast rest for 10-15 minutes before slicing to allow juices to redistribute.

Step-by-Step Instructions

Follow these simple steps for grilling pork sirloin roast to juicy perfection:

1. Prepare the Roast

Take a 2-3 lb pork sirloin roast and trim off any excess fat or silverskin. Leave about 1/4 inch of fat.
Pat the roast dry with paper towels. This helps the rub adhere better.
Coat all sides of the roast liberally with olive oil or vegetable oil.

2. Apply Rub

For incredible flavor, make a simple dry rub. Combine 1 tbsp each of garlic powder, onion powder, salt, brown sugar, and paprika.
Generously apply the rub all over the roast, coating all sides.
For extra flavor, rub it under the fatty side flap as well. Press the rub into the meat.

3. Preheat Grill

Preheat your gas or charcoal grill to 350-400°F, using an oven thermometer placed on the grate.
For charcoal, spread hot coals evenly for indirect cooking.
For gas, turn off the burner where the pork will be placed.

4. Grill the Roast

Place the seasoned pork roast on the grill grate over indirect heat, with the fatty side up.
Close the grill, vent open. Grill for 90-120 minutes, with the lid closed as much as possible.
Use tongs to turn the roast every 30 minutes for even cooking.
Insert a digital meat thermometer into the thickest part. Grill until it reaches 145°F.

5. Rest and Slice

Transfer the roast to a cutting board and tent it loosely with foil.
Allow it to rest for 10-15 minutes to let juices redistribute.
Carefully slice the pork against the grain into 1/2 inch thick slices.
Serve warm with your favorite sides and enjoy!
