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.
Step 5. Lay the roast in the pan with the fatty side up so the juices will baste the roast naturally while cooking. Step 6. Cook for 12 to 25 minutes per pound of tri-tip, depending on how well-done you want the roast. When the internal temperature reaches 125 degrees, the roast is rare. A temperature between 130 to 135 degrees is medium rare, with a 145-degree internal temperature denoting a well-done roast.
