How To Cook Tri Tip On Bbq

ByLily

Firing up the BBQ for tri tip is all about balancing high searing heat with a gentle finish over indirect coals. If you want to know how to cook tri tip on bbq, the process is simpler than you think, but it does require a two-zone fire and a good instant-read thermometer.

Tri tip is a triangular cut from the bottom sirloin. It is lean, flavorful, and cooks fast compared to brisket or pork shoulder. That makes it perfect for a weeknight or a weekend cookout.

In this guide, you will learn how to set up your grill, season the meat, sear it, and slice it the right way. Follow these steps and you will get a juicy, tender roast every time.

What You Need Before You Start

Gather your tools and ingredients first. This keeps you from running around once the coals are hot.

  • One whole tri tip roast, about 2 to 3 pounds
  • Kosher salt and coarse black pepper
  • Garlic powder or your favorite dry rub
  • A charcoal or gas grill with a lid
  • An instant-read meat thermometer
  • A sharp carving knife
  • Aluminum foil for resting

If you use a gas grill, make sure you have at least two burners so you can create a hot side and a cool side. For charcoal, you will need a chimney starter and enough briquettes to fill half the grill.

This is the core method. It uses a reverse sear style approach, but with a hot sear first and a slower finish. That gives you a dark crust and even doneness inside.

Step 1: Trim And Season The Roast

Pat the tri tip dry with paper towels. Look for a thick fat cap on one side. You can trim it down to about a quarter inch, but do not remove it all. The fat adds flavor and helps protect the meat.

Season generously on all sides with salt, pepper, and garlic powder. Use more than you think you need. A good rule is one teaspoon of salt per pound of meat.

Let the seasoned roast sit at room temperature for 30 minutes while you prepare the grill. This helps it cook more evenly.

Step 2: Set Up A Two-Zone Fire

For charcoal, light a full chimney of briquettes. Once they are ashy gray, pour them on one half of the grill. Leave the other half empty. That empty side is your indirect zone.

For gas, turn the burners on one side to high and leave the other side off. Close the lid and let the grill heat up for 10 minutes.

You want the hot side around 450 to 500 degrees Fahrenheit. The cool side should be around 250 to 300 degrees.

Step 3: Sear The Tri Tip Directly

Place the tri tip over the hot coals or the lit burners. Sear it for 3 to 4 minutes per side without moving it. You want a deep brown crust.

Use tongs to flip it once. Do not poke it with a fork, because that lets juices escape.

After both sides are seared, move the roast to the cool side of the grill. Close the lid.

Step 4: Finish Over Indirect Heat

Cook with the lid closed for 15 to 25 minutes. The exact time depends on the size of your roast and the temperature of your grill.

Check the internal temperature every 5 minutes with your thermometer. Insert it into the thickest part of the meat.

  • Rare: 125 degrees Fahrenheit
  • Medium rare: 130 to 135 degrees Fahrenheit
  • Medium: 140 to 145 degrees Fahrenheit

Pull the tri tip off the grill when it is 5 degrees below your target. The temperature will rise as it rests.

Step 5: Rest And Slice Against The Grain

Wrap the roast loosely in foil and let it rest for 10 minutes. This allows the juices to redistribute. If you cut it right away, the juice will run out and the meat will be dry.

Now here is the most important part. Look at the direction of the muscle fibers on the roast. They change direction in the middle of a tri tip. You need to slice against the grain, which means cutting perpendicular to those fibers.

Start at the narrow end and cut thin slices, about a quarter inch thick. When you reach the point where the grain changes, rotate the roast and keep slicing against the new grain direction.

Tips For Better Results

These small details make a big difference.

  • Do not skip the rest. Ten minutes minimum.
  • Use a thermometer, not a timer. Every grill runs different.
  • If the crust is getting too dark, move the roast to the cool side sooner.
  • Let the grill lid stay closed during indirect cooking. Opening it loses heat.
  • For extra flavor, add a chunk of oak or hickory to the coals.

Common Mistakes To Avoid

Even good cooks run into problems with tri tip. Here is what to watch out for.

Cooking It Like A Steak

Tri tip is thicker than a steak. If you cook it entirely over high heat, the outside will burn before the inside is done. Always use a two-zone setup.

Slicing With The Grain

This is the number one reason tri tip turns out chewy. Take a close look at the meat before you cut. If the slices look stringy, you are going the wrong way.

Not Letting It Rest

Patience here pays off. A rested roast is juicier and easier to slice.

Serving Suggestions

Tri tip is great on its own, but it also works well in other dishes.

  • Slice it thin for sandwiches on crusty rolls
  • Serve with grilled corn and a simple green salad
  • Pile it on tacos with salsa and avocado
  • Chop leftovers for chili or hash

Store any leftover tri tip in the fridge for up to four days. Reheat it gently in a skillet over low heat so it does not dry out.

Now you have a clear plan for your next cookout. Get your coals ready, season that roast, and follow the steps above. With a little practice, you will be cooking tri tip on the BBQ like a pro.
