Barbecuing a tri tip on a gas grill is one of the best ways to enjoy this flavorful and tender cut of beef. The triangular shape of tri tip makes it ideal for both searing and slow finishing, giving you a beautiful crust and juicy interior. With proper preparation, timing, and temperature control, you can turn this simple cut into a delicious centerpiece for any barbecue.

1. Preparing the Tri Tip

Start by trimming off excess fat, leaving a thin layer for flavor. Then season the meat generously with salt, pepper, garlic powder, and herbs like rosemary or thyme. For a richer taste, marinate the tri tip for at least 2 hours, or overnight in the refrigerator. Before grilling, take it out and let it rest at room temperature for 30 minutes to ensure even cooking.

2. Preheating the Grill and Setting Zones

Preheat your gas grill for about 10–15 minutes with the lid closed. Set one side of the grill to high heat (450–500°F / 230–260°C) and the other side to medium or low heat (300–350°F / 150–175°C). This creates two cooking zones: one for searing and one for finishing the roast. A two-zone setup ensures that the tri tip cooks evenly without burning the exterior.

3. Searing the Tri Tip

Once the grill reaches temperature, place the tri tip on the high-heat zone. Sear each large side for 4–5 minutes, turning as needed to develop a dark, caramelized crust. Keep the lid open during this step to avoid flare-ups. This searing process locks in juices and creates that classic grilled flavor.

4. Finishing Over Indirect Heat

After searing, move the tri tip to the medium or low-heat zone and close the lid. Cook the meat slowly until it reaches your preferred internal temperature. Use a meat thermometer to check doneness rather than cutting into the meat.

Tip: Always cook to temperature, not time. Gas grills can vary depending on brand, BTU level, and outdoor conditions.

5. Resting and Slicing

Once your tri tip reaches the desired temperature, remove it from the grill and let it rest under foil for 10–15 minutes. Resting allows the juices to redistribute throughout the meat, keeping it moist and tender. When slicing, always cut against the grain, as this shortens muscle fibers and enhances tenderness.

6. Helpful Grilling Tips

• Avoid flipping too often – two or three turns are enough.

• Use a thermometer for accuracy instead of guessing.

• Keep lid closed during indirect cooking to retain heat.

• Oil the grates before cooking to prevent sticking.

• Clean after use to maintain grill performance and hygiene.

7. Flavor Enhancements

You can customize your tri tip flavor profile by adding:

• Smoked paprika or chili rub for a spicy crust.

• Wood chips in a smoker box for a smoky aroma.

• Glazed butter or garlic sauce brushed on during the final minutes of grilling.

These simple touches elevate the taste without complicating the cooking process.

8. Conclusion

Barbecuing a tri tip on a gas grill takes around 30 to 50 minutes depending on size and doneness. The process is straightforward: sear first over high heat, then finish slowly over indirect heat. With attention to temperature and resting time, you’ll achieve a perfectly juicy, flavorful roast.
