Sirloin Tip Roast Recipe Traeger: Wood-Fired Flavor with Melt-In-Your-Mouth Tenderness

I tested this one in my tiny Boston kitchen, and it’s a game-changer for Traeger owners. The wood-fired flavor turns a humble sirloin tip into something extraordinary.

This method delivers melt-in-your-mouth tenderness without fancy techniques. Just season, smoke, and let the Traeger do the work.

Low and slow is the secret—around 225°F until it hits that perfect internal temp. Every bite carries that smoky depth you can’t fake.

Serve it up with roasted veggies or mashed potatoes. Honestly, leftovers might be even better the next day.

Ingredients for Sirloin Tip Roast Recipe Traeger

Wood-fired magic starts with this simple but intentional ingredient list for your Traeger.

The roast is everything here. Look for a well-marbled sirloin tip—it’s leaner than chuck but still tender when cooked low and slow. Costco has great options in bulk, or ask your butcher to cut a custom piece. Avoid anything with heavy connective tissue. The kosher salt (I swear by Diamond Crystal) makes a noticeable difference in the crust formation.

No smoked paprika? Regular paprika plus a pinch of chipotle powder works in a pinch. Swap fresh garlic for the powder at a 3:1 ratio (3 cloves = 1 tbsp powder). The beef broth can be homemade or Better Than Bouillon paste—just watch the salt. For extra depth, add a splash of Worcestershire sauce (or coconut aminos for a non-fish option).

Leftovers keep beautifully—shred for sandwiches or slice thin for tacos. Stores 4-5 days in the fridge, freezes for 3 months. Reheat gently in the broth to prevent drying out (trust me on this one).

Step-by-Step Instructions for Sirloin Tip Roast on Traeger

Here’s how I achieve melt-in-your-mouth tenderness with wood-fired flavor every time.

Step 1: Create the Flavorful Dry Rub

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, 2 tsp Smoked Paprika, 1 tsp Dried Rosemary, and 1 tsp Dried Thyme. I always crush the rosemary and thyme between my fingers to release their oils—this makes a huge difference in flavor intensity.

This blend delivers a balanced profile: the salt and pepper provide the foundation, while the smoked paprika adds depth that complements the Traeger’s wood smoke. The garlic and onion powders create that classic savory base we all love in a good roast.

Step 2: Prep and Season the Roast

Pat the 3 lb Sirloin Tip Roast dry with paper towels to ensure the rub adheres properly. I like to trim any large fat caps, but leave a thin layer for flavor and moisture. Brush the entire surface with the 1 tbsp Yellow Mustard and 1 tbsp Apple Cider Vinegar—this helps the dry rub stick and adds a subtle tang.

Now coat the roast evenly with the dry rub, pressing it gently into the meat so it forms a crust during cooking. Then drizzle with the 2 tbsp Olive Oil and rub it all over to create a sealed surface. Let it sit at room temperature for 30-45 minutes while you preheat your Traeger.

Step 3: Smoke to Perfection on the Traeger

Preheat your Traeger to 225°F with your preferred wood pellets—I use hickory or oak for this roast. Once the grill reaches temperature, place the sirloin tip roast directly on the grates. Insert a meat probe if your model supports it.

Smoke the roast undisturbed until the internal temperature reaches 135°F for medium-rare, which typically takes 2-2.5 hours for a 3 lb roast. You’ll know it’s getting close when the exterior develops a rich, dark bark. Resist the urge to peek—every time you open the lid, you lose heat and smoke.

Step 4: Rest and Serve with Pan Juices

Remove the roast from the Traeger when it hits 135°F and transfer it to a cutting board. Tent it loosely with aluminum foil and let it rest for 15-20 minutes. This step is non-negotiable—it allows the juices to redistribute for maximum tenderness.

While it rests, pour the 1 cup Beef Broth into a small saucepan and bring to a simmer. Whisk in the 2 tbsp Unsalted Butter until melted, then use this to baste the roast just before slicing. The combination of smoky crust, juicy interior, and this simple au jus takes this dish to the next level.

Pro Cooking Tips for This Recipe

Pellet Selection Matters

For this cut, I always use hickory or oak pellets on my Traeger. Hickory gives a stronger, bacon-like smoke that stands up to beef, while oak offers a more subtle, balanced flavor. Avoid mesquite—it can overpower the meat. 🌡️

Temperature Control

Maintain a steady 225°F throughout the cook. I check my Traeger’s built-in thermometer against a ThermoWorks Smoke probe for accuracy. Fluctuations above 250°F can dry out the sirloin tip before it reaches perfect doneness.

The Bark Trick

When the roast hits 110°F internal, spritz with apple juice every 45 minutes. This keeps the surface moist while building that coveted dark bark. I use a spray bottle from my Boston kitchen for even coverage.

Probe Placement

Insert your meat probe into the thickest part, avoiding fat pockets. For a 3 lb roast, the center is usually ideal. I learned this the hard way after pulling one too early—now I wait for 135°F for perfect medium-rare.

Resting Technique

After pulling at 135°F, tent with foil and rest for 20 minutes. I place it on a wire rack over a baking sheet to prevent steam from making the bark soggy. This step ensures juices redistribute properly. 💪

Slicing Against Grain

Locate the grain direction before slicing—it runs perpendicular to the long axis of the roast. Cut against it in ¼-inch slices for maximum tenderness. My Nonna’s knife skills come in handy here.
