How Long To Cook Tri Tip On Grill

ByLily

Grilling tri tip requires understanding direct and indirect heat zones to nail that perfect slice. So, how long to cook tri tip on grill? For a standard 2 to 3 pound roast, plan on about 25 to 35 minutes total over medium-high heat, aiming for an internal temperature of 130°F to 135°F for medium-rare. The exact time shifts based on roast size, grill temp, and weather conditions outside.

Tri tip is a triangular cut from the bottom sirloin. It’s lean, flavorful, and cooks fast compared to brisket or pork shoulder. That makes it a great weeknight option once you know the timing.

The Best Way To Grill Tri Tip For Consistent Results

Before you worry about minutes, set up your grill properly. A two-zone fire gives you control. You sear over high heat, then finish over indirect heat so the inside cooks evenly without burning the crust.

Set Up Two Heat Zones

  • For gas: turn one burner to high, leave the other off. Close the lid to build ambient heat.
  • For charcoal: pile lit coals on one side of the grill. Leave the other side empty.
  • Target 450°F to 500°F over the direct zone and 300°F to 350°F on the indirect side.

If you skip the two-zone setup, you risk a charred outside and a raw center. Tri tip is thick at one end and thin at the other, so even cooking needs gentle heat after the sear.

Season And Prep The Roast

Pat the roast dry with paper towels. Moisture steams the meat instead of searing it. Apply a simple rub of salt, black pepper, garlic powder, and a little smoked paprika. Let it sit at room temp for 20 to 30 minutes before grilling.

Here’s the timing breakdown you came for. These numbers assume a 2 to 3 pound roast and a grill running at the temps above.

Time By Desired Doneness

  • Rare (120°F to 125°F): 20 to 25 minutes total
  • Medium-rare (130°F to 135°F): 25 to 35 minutes total
  • Medium (140°F to 145°F): 35 to 40 minutes total
  • Medium-well (150°F+): 40 to 45 minutes total, but expect a drier slice

These times include the sear and the indirect finish. Always trust a meat thermometer over the clock. Insert it into the thickest part, away from fat and bone.

Step-By-Step Grilling Process

  1. Preheat your grill with both zones ready. Clean and oil the grates.
  2. Place the tri tip over direct high heat. Sear for 4 to 5 minutes per side.
  3. Move the roast to the indirect zone. Close the lid.
  4. Cook for 15 to 25 more minutes, flipping once halfway through.
  5. Check the internal temp at the 20-minute mark. Pull it 5 degrees before your target temp.
  6. Rest the meat on a cutting board for 10 minutes under foil.
  7. Slice against the grain into thin strips.

Resting matters more than most people think. The juices redistribute, and the temp rises another 5 to 10 degrees. If you cut too early, the board gets a pool of juice and the meat turns dry.

Adjusting For Roast Size

A 1.5 pound tri tip cooks in about 18 to 22 minutes. A 4 pound roast may need 40 to 50 minutes. The thickness matters more than the weight. A thick, compact roast takes longer than a long, flat one of the same weight.

Cold meat also slows things down. If you go straight from the fridge to the grill, add 5 to 8 minutes to your estimate.

Common Mistakes That Ruin Tri Tip

  • Slicing with the grain. Tri tip has two grain directions. Look closely and cut across both.
  • Overcooking past 140°F. This cut has little fat, so it dries out fast.
  • Opening the lid every few minutes. Each peek drops the temp and adds time.
  • Using a sugary rub over high heat. It burns before the inside cooks.
  • Skipping the rest. Ten minutes is not optional.

Grill Temperature And Timing Chart

Use this quick reference when you fire up the grill.

  • High direct sear: 4 to 5 minutes per side
  • Indirect at 325°F: 15 to 25 minutes
  • Total cook time: 25 to 35 minutes for medium-rare
  • Rest time: 10 minutes
  • Final internal temp after rest: 130°F to 135°F

How To Tell When Tri Tip Is Done

A digital thermometer is the only reliable method. The touch test works for steaks, but tri tip varies in thickness, so feel alone can fool you. Check the thickest section and the thin end separately.

If the thin end hits 130°F before the thick end, move the roast so the thick side faces the heat source. Or tent the thin end with foil.

What If You Don’t Have A Thermometer?

Press the center of the roast with tongs. Rare feels soft and squishy. Medium-rare has a slight spring. Medium feels firm with little give. This method is rough, so buy a thermometer when you can. They cost less than one ruined roast.

Resting, Slicing, And Serving

Let the meat rest for 10 minutes on a cutting board. Do not wrap it tight in foil, or the crust turns soft. A loose tent is fine.

Find the grain lines on the flat end. They usually run at an angle. Slice thin, about a quarter inch, against those lines. When you reach the point where the grain shifts, rotate the roast and keep slicing against the new direction.

Serve with grilled vegetables, a simple salad, or warm tortillas. Leftovers keep in the fridge for three days and taste great in sandwiches or tacos.

Final Timing Tips

  • Start checking temps 5 minutes before your estimated finish time.
  • Windy days add 5 to 10 minutes. Cold weather adds more.
  • Let the grill preheat fully. Rushing this step throws off every time estimate.
  • Keep a log of your cooks. Note the weight, temp, and total minutes. After two or three tries, you will nail the timing for your setup.

With a two-zone fire and a thermometer, tri tip becomes one of the easiest roasts to grill. Stick to 25 to 35 minutes for medium-rare, rest it well, and slice against the grain. You will get tender, juicy slices every time.
