A tri tip on the gas grill should be cooked over indirect heat for best results. This cut of beef is lean and can dry out fast if you treat it like a steak. Learning how to cook tri tip on gas grill is simple once you understand the two-zone fire method. You will get a smoky crust and a juicy, pink center every time.
Tri tip comes from the bottom sirloin. It has a triangular shape and a thick fat cap on one side. The grain runs in two different directions, which matters when you slice it. This guide will walk you through every step from seasoning to resting.
Why The Gas Grill Works For Tri Tip
Gas grills give you precise temperature control. You can set one side to high heat and the other to low or off. This setup lets you sear the meat first, then finish it slowly without burning the outside. Charcoal grills work too, but gas is easier for beginners.
The key is to avoid flare-ups. Tri tip has enough fat to cause flames if you cook it directly over high heat the whole time. By using indirect heat for most of the cook, you keep the meat tender.
How To Cook Tri Tip On Gas Grill
Step 1: Choose The Right Tri Tip
Look for a tri tip that weighs 1.5 to 2.5 pounds. It should have a thick, even fat cap on one side. The meat should be bright red with no gray or brown spots. If the fat cap is too thin, the meat may dry out.
You can buy tri tip trimmed or untrimmed. If it has a thick fat layer, leave about 1/4 inch of fat on top. Trim off any hard, yellow fat.
Step 2: Season The Meat
Seasoning is simple. You need salt and pepper at minimum. For a classic Santa Maria style, use garlic powder, onion powder, and a little paprika. Rub the seasoning all over the meat, including the fat cap. Let it sit at room temperature for 30 to 45 minutes before grilling.
Do not skip the rest time. Cold meat cooks unevenly on the grill. A room-temperature tri tip will cook more evenly.
Step 3: Set Up Your Gas Grill For Two-Zone Cooking
Turn all burners to high and close the lid. Let the grill heat up for 10 to 15 minutes. Then turn off one or two burners on one side. You want one side hot (around 450°F to 500°F) and the other side cool (around 250°F to 300°F).
Place a drip pan under the grate on the cool side if you want to catch fat. This step is optional but helps prevent flare-ups.
Step 4: Sear The Tri Tip
Place the tri tip directly over the hot burners. Sear each side for 3 to 4 minutes. You want a deep brown crust, not black. Use tongs to flip the meat. Do not poke it with a fork, or you will lose juices.
Sear the fat cap side last. This renders the fat and adds flavor. The whole searing process should take about 8 to 12 minutes.
Step 5: Move To Indirect Heat
After searing, move the tri tip to the cool side of the grill. Place it with the fat cap facing up. Close the lid. Let it cook slowly until it reaches your desired internal temperature.
For medium-rare, aim for 130°F to 135°F. For medium, go to 140°F to 145°F. Do not cook it past 150°F or it will be tough.
Use a meat thermometer inserted into the thickest part of the meat. Check the temperature every 10 minutes after the first 20 minutes of indirect cooking.
Step 6: Rest The Meat
Once the tri tip hits your target temperature, remove it from the grill. Place it on a cutting board and tent it loosely with foil. Let it rest for 10 to 15 minutes. Resting allows the juices to redistribute. If you cut it too soon, the juices will run out and the meat will be dry.
Step 7: Slice Against The Grain
Tri tip has two grain directions. Look at the meat and find the lines of muscle fiber. Slice perpendicular to those lines. For the narrow end, the grain runs one way. For the wider end, it runs another way. Slice each section separately.
Cut the slices about 1/4 inch thick. Thinner slices are more tender. Serve immediately or keep warm in a low oven.
Common Mistakes To Avoid
Overcooking The Meat
Tri tip is lean and cooks fast. If you leave it on the grill too long, it becomes dry and chewy. Use a thermometer and pull it off 5°F below your target temp. The temperature will rise during resting.
Skipping The Rest
Resting is not optional. Without it, the juices spill out when you slice. The meat will taste dry even if you cooked it perfectly.
Not Trimming The Fat Cap
A thick fat cap can cause flare-ups. Trim it to 1/4 inch. If you leave it too thick, the fat may not render fully and will taste rubbery.
Using Direct Heat The Whole Time
Direct heat only works for thin steaks. Tri tip needs indirect heat to cook through without burning the outside. Always sear first, then move to the cool side.
Temperature Guide For Tri Tip
- Rare: 125°F (remove from grill at 120°F)
- Medium-rare: 130°F to 135°F (remove at 125°F to 130°F)
- Medium: 140°F to 145°F (remove at 135°F to 140°F)
- Medium-well: 150°F to 155°F (not recommended for tri tip)
- Well done: 160°F+ (will be tough)
For the best flavor and texture, stick with medium-rare or medium. Anything past medium-well will be disappointing.
How To Add Smoke Flavor On A Gas Grill
Gas grills do not produce smoke like charcoal or wood. But you can add smoke flavor easily. Use a smoker box or a foil packet filled with wood chips. Place it directly over the hot burners during the searing phase.
Soak wood chips in water for 30 minutes first. Drain them and put them in the smoker box or foil packet. Poke holes in the foil. The chips will smolder and produce smoke.
Good wood choices for tri tip are oak, hickory, or mesquite. Oak is traditional for Santa Maria style. Mesquite is stronger, so use less.
Marinades And Rubs For Tri Tip
Simple Dry Rub
- 2 teaspoons kosher salt
- 1 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon paprika
Mix and apply generously. Let it sit for at least 30 minutes.
Santa Maria Style Rub
- 2 teaspoons salt
- 1 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika
- 1/2 teaspoon cayenne (optional)
This rub is classic for California-style tri tip. It pairs well with a simple salsa or grilled vegetables.
Wet Marinade Option
If you prefer a marinade, use a mix of olive oil, soy sauce, Worcestershire sauce, garlic, and rosemary. Marinate for 2 to 4 hours in the fridge. Do not marinate longer than 6 hours or the acid will break down the meat too much.
Pat the meat dry before grilling. A wet surface will not sear properly.
What To Serve With Tri Tip
Tri tip goes well with simple sides. Grilled vegetables like asparagus, bell peppers, and zucchini are good. A green salad with vinaigrette cuts the richness. Garlic bread or roasted potatoes also work.
For a Santa Maria style meal, serve with pinquito beans, salsa, and grilled French bread. This is the traditional pairing in California.
Storing And Reheating Leftovers
Store leftover tri tip in an airtight container in the fridge for up to 4 days. To reheat, slice the meat and warm it in a skillet over medium heat with a little beef broth. Do not microwave it, or it will become tough.
You can also use leftover tri tip for sandwiches, tacos, or salads. Slice it thin and add to a bun with horseradish sauce for a quick lunch.
Frequently Asked Questions
Can I Cook Tri Tip Directly Over High Heat The Whole Time?
No, that will burn the outside and leave the inside raw. Use indirect heat for most of the cook. Sear first, then move to the cool side.
How Long Does It Take To Cook Tri Tip On A Gas Grill?
Total time is about 30 to 45 minutes. Searing takes 8 to 12 minutes. Indirect cooking takes 20 to 30 minutes depending on thickness and desired doneness.
Do I Need To Flip The Tri Tip During Indirect Cooking?
Flipping is optional. You can leave it fat cap up the whole time. If you want more even cooking, flip it once halfway through.
What If I Don’t Have A Meat Thermometer?
You can use the touch test, but it is not accurate for tri tip. A thermometer is highly recommended. Without one, you risk overcooking or undercooking.
Can I Marinate Tri Tip Overnight?
It is not recommended. The acid in most marinades will break down the meat fibers too much. Stick to 2 to 4 hours for best texture.
Final Tips For Perfect Tri Tip
Let the meat rest before slicing. Slice against the grain. Use a sharp knife. Serve with a simple sauce like chimichurri or horseradish cream.
Practice makes perfect. The first time you cook tri tip, it might not be perfect. That is fine. Adjust your grill temperature and timing next time. You will get better with each cook.
Remember that the internal temperature will rise about 5°F during resting. Pull the meat off the grill a little early to account for this. A medium-rare tri tip should be removed at 125°F to 130°F.
If you want a darker crust, sear for an extra minute per side. But watch closely so it does not burn. Burnt seasoning tastes bitter.
Gas grills vary in heat output. Some run hotter than others. Learn your grill’s hot spots. Use an oven thermometer on the grate to check actual temperature. This will help you get consistent results.
Tri tip is a forgiving cut if you follow the indirect heat method. It is also affordable compared to other roasts. You can feed four people with one tri tip easily. Leftovers are great for sandwiches the next day.
So fire up your gas grill, season that tri tip, and cook it low and slow after a good sear. You will end up with a juicy, flavorful roast that impresses everyone at the table.
