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.
Remove the meat from the marinade and pat the extra marinade off with paper towels. Place your tri-tip on a low-temperature spot on the grill, once your grill is ready. Grill your tri-tip, turning it occasionally with grilling tongs, until it is medium-rare---about 35 to 40 minutes.The tri-tip's internal temperature should be 135 degrees F when you cook it, which is just below medium-rare. Remove the tri-tip from the grill onto a platter. Let it rest for 15 to 20 minutes.During this time, the tri-tip's internal temperature will continue to rise 5 to 10 degrees F, cooking it to medium-rare.repare your barbecue grill while your tri-tip is coming up to temperature. If you are using a charcoal grill, rake the coals slightly to one side of the grill so that you will have a low-temperature spot, away from the flames, where you can cook your tri-tip.
