How Long to Cook Tri Tip on BBQ

Tri tip is a triangular cut of beef from the bottom sirloin that is popular on the west coast of the United States. When cooked correctly on the barbecue, it can be incredibly flavorful, tender and juicy. But knowing exactly how long to cook tri tip can be tricky. Here is a detailed guide on how long you should cook tri tip on the barbecue to get perfect results.

Introduction to Tri Tip

Tri tip has become a specialty in central California, but it has grown in popularity nationwide. It has a rich beefy flavor and can be prepared similarly to other grilling cuts like skirt or flank steak. Here’s a quick overview of tri tip:

Tri tip is a small triangular cut of beef from the bottom sirloin, weighing 1.5 to 2.5 pounds.
It has moderate marbling which gives it good natural moisture and flavor.
When cooked correctly, it is very tender and juicy.
It can be grilled, smoked, braised or roasted. Grilling tri tip on a BBQ is a popular preparation.
It’s important not to overcook tri tip or it can become tough.
Proper cooking times and temperatures are key for tender, juicy results.

Cooking times can vary considerably based on the thickness of the tri tip, type of BBQ, temperature control, and doneness preferred. Here are some general guidelines:

1. Thickness of the Tri Tip

1-inch thick – Grill for 45 to 60 minutes
1 1/2 to 2 inches thick – Grill for 60 to 75 minutes
2 1/2 to 3 inches thick – Grill for 75 to 90 minutes

The thicker the tri tip, the more time it will need on the grill. A meat thermometer is highly recommended to check for doneness.

2. Type of BBQ

Gas Grill – Higher heat allows for quicker cooking. Aim for 400-450°F.
Charcoal Grill – Slower, indirect heat around 325-375°F.
Smoker – Low, indirect heat of 225-275°F for very slow cooking.

Gas grills allow for faster cooking at higher heats. Smokers and charcoal grills use lower heat for slower cooking times.

3. Temperature Control

Cook over direct high heat first to sear both sides.
Then move to indirect lower heat to finish cooking more gently.
Try to maintain a steady temperature, not too hot or cold.
Avoid flare-ups from dripping fat causing burnt spots.

Controlling the temperature is key – high heat to sear, followed by lower gentle heat to cook through.

4. Doneness Preference

Rare – Cook to 135°F internal temp – red cool center.
Medium Rare – Cook to 145°F – warm red center.
Medium – Cook to 155°F internal temp – pink warm center.
Medium Well – Cook to 165°F – small amount of pink.
Well Done – Cook to 170°F+ – brown throughout, no pink.

Use a meat thermometer to test for doneness based on preference. Medium rare is recommended for most tender, juicy results.
