Sirloin Tip Roast Recipe Pellet Grill: Wood-Fired Tenderness with Bold Smoke

My pellet grill has turned more tough cuts into tender masterpieces than I can count, and this sirloin tip roast proves it every time.

Low and slow smoke transforms this lean cut into juicy, flavorful perfection. The key is maintaining a steady 225°F while letting the wood do the work.

I developed this method after years of competition cooking, where consistency separates good from great. A simple dry rub enhances without overpowering.

What emerges is a roast with a beautiful bark and pink center that slices like butter. Serve it with roasted vegetables for a complete meal.

Ingredients for Sirloin Tip Roast Recipe Pellet Grill

Lean cut, bold smoke, simple rub. Pellet grill does the rest for this showstopper.

The sirloin tip roast is the star—look for marbling throughout (not just on the surface) at your butcher or Costco. Avoid pre-cut steaks; a whole roast gives you better control over thickness. Diamond Crystal kosher salt is my go-to for the dry rub—its coarse texture adheres better and draws out moisture for that perfect bark. Don’t skip toasting your spices if using whole (I keep a dedicated coffee grinder for this).

No smoked paprika? Regular paprika plus a pinch of chipotle powder works. Fresh herbs can replace dried at triple the amount, but they’ll burn faster—spritz with water during the cook. Traeger’s signature blend pellets are great, but any 100% hardwood (no fillers) works. If you’re out of apple cider vinegar, white vinegar in a pinch—just use half as much.

Store the roast wrapped in the fridge for up to 4 days before cooking, or freeze for 6 months. Leftovers (if any) slice beautifully for sandwiches and keep 5 days refrigerated. The dry rub mix keeps 3 months in a cool, dark place—make extra for next time.

Step-by-Step Instructions for Sirloin Tip Roast on Pellet Grill

This method delivers that perfect balance of smoky depth and fall-apart tenderness you’re after.

Step 1: Prepare the Sirloin Tip Roast with Dry Rub

Pat the 3 lb Sirloin Tip Roast completely dry with paper towels. This ensures the dry rub adheres properly and creates that beautiful bark we’re aiming for. Trim any remaining excess fat if needed.

In a small bowl, combine the 1.5 tbsp Coarse Kosher Salt, 1 tbsp Freshly Ground Black Pepper, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 1 tsp Smoked Paprika, 1 tsp Dried Thyme, and 1 tsp Dried Rosemary. Rub the herbs between your fingers as you mix to release their essential oils.

Brush the 2 tbsp Yellow Mustard evenly over the entire surface of the roast. This acts as a binder for the dry rub. Then coat the roast thoroughly with the spice mixture, pressing it into the meat so it sticks. Drizzle the 2 tbsp Olive Oil over the roast and rub it in, then finish with the 1 tbsp Apple Cider Vinegar for a touch of brightness.

Step 2: Preheat and Set Up the Pellet Grill

Fill your pellet grill hopper with the 20 lb Pellet Grill Wood Pellets—hickory or oak work beautifully here. Preheat the grill to 225°F using the smoke or low setting. This temperature allows for a slow cook that breaks down the connective tissue without drying out the meat.

Once preheated, place a water pan or drip tray filled with water on the grill grates. This adds moisture to the cooking environment, which is especially important for leaner cuts like sirloin tip. The water also helps maintain a consistent temperature throughout the cook.

Step 3: Smoke the Roast to Perfection

Place the seasoned roast directly on the grill grates, fat-side up. Insert a meat probe into the thickest part of the roast, avoiding any large pockets of fat. Close the lid and smoke undisturbed for 2 to 2.5 hours.

You’re aiming for an internal temperature of 130-135°F for medium-rare. Resist the urge to peek—every time you open the lid, you lose heat and smoke. The roast is ready when the probe slides in with minimal resistance and the bark has developed a deep, rich color.

Step 4: Rest and Slice for Maximum Tenderness

Once the roast reaches your desired internal temperature, remove it from the grill and transfer it to a cutting board. Tent it loosely with aluminum foil and let it rest for 15-20 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful.

After resting, slice the roast against the grain into ½-inch thick slices. Slicing against the grain shortens the muscle fibers, making each bite more tender. Serve immediately while still warm, with any accumulated juices spooned over the top for extra flavor.

Dietary Considerations for This Recipe

Gluten-Free Friendly

This dish is naturally gluten-free as written, with no flour or breadcrumbs in the rub or cooking process. I always verify my spices at the store—some brands add anti-caking agents that may contain gluten. Stick with McCormick or Penzeys for safe options. 💪

Low-Carb Option

With zero added sugars and only 3g net carbs per serving from the rub, this fits perfectly into keto or low-carb diets. The apple cider vinegar adds minimal carbs while balancing flavors beautifully.

Dairy-Free Naturally

No butter, cheese, or cream here—just meat and spices. This makes it ideal for dairy-sensitive folks. I’ve served this to lactose-intolerant friends at competitions without any issues.

Sodium Considerations

The recipe uses 1.5 tbsp kosher salt for 3 lbs of meat. To reduce sodium, cut the salt by half and boost other spices. The smoked paprika and herbs will still deliver bold flavor.

I’ve found Diamond Crystal salt has larger crystals, so you get more flavor with less sodium by volume.

Protein-Packed

A 4-ounce serving provides about 30g of high-quality protein. This lean cut is perfect for muscle maintenance or weight management. Pair with roasted veggies for a balanced meal. ✨
