Sear the tri-tip for about four minutes. Turn it over, and place it in a baking dish with the seared side facing up. Cook for 30 minutes for rare or medium rare meat or 45 minutes for well-done. Use a meat thermometer to check that the internal temperature is between 135 and 150 degrees, then emove the meat from the oven and place it on a cutting board.
4 Cover the grill and cook until the temperature of the interior of the tri-tip reaches 120Â°F for a rare roast, 130Â°F for medium-rare and 140Â°F for medium. At this point the meat will take anywhere from 20 to 40 minutes to cook, depending on how hot your grill is, how well done you want it, and the size of the cut. 1 tri-tip roast, also known as triangle steak, a bottom sirloin cut (anywhere from 2 1/2 pounds to 4 pounds), look for one well-marbled with fat.
