Sirloin Tip Roast on the Grill Recipe: Smoky Char with Herb-Infused Tenderness

This grilling method transforms a simple sirloin tip into a tender, smoky masterpiece. The key is slow, indirect heat that breaks down the fibers while building deep flavor.

I developed this technique after years of trial and error, perfecting the balance between charred exterior and juicy interior. The herb infusion adds complexity that elevates every bite.

A select cut, bold herbs, and smoky depth transform this into a standout dish.

The sirloin tip must be well-marbled for optimal tenderness. Whole Foods or Costco typically carry high-quality cuts with consistent marbling. Ask your butcher for a center-cut piece if available, as it provides the most uniform thickness. The Diamond Crystal kosher salt is essential for proper seasoning adhesion—its coarse texture and lack of additives make it superior for dry brining. Fresh herbs from the farmers market or a well-stocked grocer like Trader Joe’s deliver the vibrant flavor this technique demands.

No fresh rosemary? Dried rosemary at half the amount works, though the flavor profile will be more concentrated. Fresh thyme can be swapped for fresh sage or oregano in equal measure. If you lack hickory chips, apple or cherry wood provides a milder smoke that still complements the beef. The Worcestershire sauce can be replaced with soy sauce plus a pinch of sugar, though the depth of flavor will differ slightly.

The roast benefits from resting 15-20 minutes before slicing to redistribute juices. Leftovers keep well in the fridge for 3-4 days or can be frozen for up to 3 months. Slice against the grain before storing for easier reheating and serving.

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

Master the technique for tender, smoky results with precise timing and temperature control.

Step 1: Prepare the Herb Marinade

In a bowl, whisk together the 0.25 cup Olive Oil, 2 tbsp Red Wine Vinegar, 2 tbsp Dijon Mustard, and 2 tbsp Worcestershire Sauce until fully emulsified. This creates the flavor base that penetrates deep into the meat.

Add the 2 tbsp Kosher Salt, 1 tbsp Coarse Black Pepper, 6 cloves Garlic Cloves (smashed), 4 pieces Fresh Rosemary Sprigs, and 4 pieces Fresh Thyme Sprigs. The herbs should be bruised slightly to release their aromatic oils. Let the 3 lb Sirloin Tip Roast marinate in this mixture for at least 4 hours or overnight for maximum tenderness.

Step 2: Preheat the Grill and Soak Wood Chips

Soak the 2 cups Hickory Wood Chips in water for 1 hour to prevent them from burning too quickly. Drain them just before use—excess water causes steam rather than smoke.

Preheat your grill to 275°F for indirect cooking. If using a charcoal grill, bank the coals to one side. For gas grills, turn off the center burners and leave the outer ones on. This setup ensures even, low-temperature cooking that prevents the roast from drying out.

Step 3: Sear and Smoke the Roast

Remove the sirloin tip roast from the marinade (reserve the marinade) and pat it dry. Sear it directly over high heat for 3-4 minutes per side until a deep, dark brown crust forms. This step locks in juices and creates a flavorful bark.

Move the roast to the indirect heat side of the grill. Add the soaked hickory wood chips to the coals or a smoker box. Place a drip pan with the 1 cup Beef Broth beneath the roast to maintain moisture. Close the lid and cook for 1.5 to 2 hours, or until the internal temperature reaches 130°F for medium-rare.

Step 4: Rest and Serve

Transfer the roast to a cutting board and tent it loosely with foil. Let it rest for 15-20 minutes—this allows the juices to redistribute, ensuring every slice is moist and flavorful. The internal temperature will rise by 5-10°F during this time.

Slice the roast against the grain into ½-inch thick pieces. The meat should be tender with a slight pink center and a robust smoky aroma. Serve immediately with the reserved marinade reduced on the stovetop for 3-5 minutes as a finishing sauce, if desired.

Make-Ahead Tips for sirloin tip roast on the grill

Marinade Prep Ahead

I always mix my marinade the night before grilling. Combine the olive oil, red wine vinegar, Dijon mustard, and Worcestershire sauce in a bowl, then whisk in the herbs and seasonings. This gives the flavors 12-24 hours to meld beautifully.

Roast Seasoning

Pat the sirloin tip roast dry, then coat it thoroughly with the marinade. Place it in a resealable bag with the marinade and refrigerate. The kosher salt will begin to penetrate the meat, enhancing tenderness and flavor absorption.

Wood Chip Prep

Soak the hickory wood chips in water for 1 hour before grilling. I like to add a splash of beef broth to the soaking water for extra flavor. Drain just before use to avoid excess steam. 🌿

Grill Setup

Prep your grill for indirect heat the morning of cooking. For charcoal, arrange coals on one side; for gas, preheat outer burners. This setup ensures even cooking at 275°F without direct flame contact.

Room Temperature Tip

Remove the marinated roast from the fridge 1 hour before grilling. This allows the meat to come to room temperature, ensuring more even cooking throughout. I find this step prevents a cold center.

Sauce Reduction

While the roast rests, reduce the reserved marinade in a saucepan over medium heat for 3-5 minutes. This creates a flavorful sauce to drizzle over the sliced meat before serving. 🔥
