How to BBQ a Sirloin Roast

A sirloin roast is a large cut of beef that comes from the back portion of the cow. Though not as naturally tender as the tenderloin sections, a properly cooked BBQ sirloin tip roast can yield moist, flavorful meat.

Barbecuing a sirloin roast on the grill adds flavor without adding fat. Because sirloin roasts benefit from long cooking times at low temperatures, you should set up the grill to use indirect heat.

Step 1: Prep Your Grill

Prepare the sirloin roast on the gas grill or charcoal grill for indirect cooking by pushing all lit coals to one side or by lighting only half of the gas grill burners. Indirect heat is preferred for a sirloin roast because it cooks the meat at a lower temperature, preventing it from burning.

Consider adding hardwood chips, soaked for at least one hour, on top of the charcoal or gas grill burner. Wood chips will infuse the sirloin roast with a smokier flavor characteristic of classic BBQ.

Step 2: Add a Drip Pan

Place a shallow drip pan filled with apple juice, beef broth, beer or wine on the empty, or unlit, side of the lower grill grate. Replace the grate on which the meat will be placed.

Step 3: Season Your Meat

Rub all sides of the sirloin roast liberally with the seasoning mix. Consider using spices that go well with traditional barbecue flavor such as pepper, garlic, mustard powder, paprika and chili powder.

Step 4: Grill Your Meat

A sirloin roast is a large cut of beef that comes from the back portion of the cow.

Place the seasoned sirloin roast over the drip pan and close the grill lid. Adjust the vents as needed to keep the temperature consistent. For a sirloin roast, aim for a grill temperature of approximately 350 degrees Fahrenheit.

If using a charcoal grill, you may have to add additional charcoal during the grilling process in order to maintain the temperature.

Step 5: Check the Temperature

Cook the roast until a meat thermometer inserted into the thickest part of the roast reads 135 degrees Fahrenheit. The Academy of Nutrition and Dietetics recommends cooking all raw meat to an internal temperature of 145 F.

However, the sirloin tip roast on the grill will continue to cook after being removed from the heat, normally rising another 5 to 10 degrees. Grilling a five-pound roast should take approximately two hours.

Step 6: Add Some Sauce

Apply barbecue sauce once the roast is removed from the heat. Applying the sauce earlier may cause the roast to burn and ruin its flavor, according to Utah State University Extension.

Step 7: Rest, Then Serve

Place the roast on a clean plate — not the one that held your meat when it was raw, as advised by Harvard Health Publishing. Tent it with aluminum foil and allow it to rest for at least 10 minutes.

Resting allows the cooking process to finish and encourages the interior juices to be distributed through the meat, keeping the meat tender. After resting, slice thinly across the grain with a sharp knife and serve.
