Pull the roast out of the refrigerator, sprinkle ¼ of the Montreal seasoning on the non-fatty side. Re-wrap and let rest for a half hour outside of the refrigerator.

Preheat the oven to 375 degrees Fahrenheit.

While oven preheats, Place the roast fat side up in a roasting pan fitted with roasting racks. Drizzle with grape seed oil and rub the roast with all the Montreal Steak seasoning. Make sure the seasoning is coated on all sides of the roast. Pour the water in the bottom of the roasting pan.

Place the roast in the oven and cook for 1 hour, 10 minutes. *Place an oven-safe thermometer in the roast to ensure internal cooking temperature. Then, reduce the heat to 250 degrees Fahrenheit and cook for an additional 20-30 minutes or until internal temperature reaches 135 degrees Fahrenheit.

Remove from the oven and let rest for 10 minutes until internal temperature reaches 145 degrees. Slice against the grain and serve immediately.
