Remove the roast from the refrigerator. Brush olive oil on all sides. Season it with your seasoning blend or dry rub, making sure to cover the entire roast.
Preheat the smoker to 225 degrees.
Sear the roast on all sides in a pan with a drizzle of oil.
Add the roast to the smoker, close the lid, and cook for 3-5 hours. For the last 1-2 hours, wrap the roast tightly in foil. When done, the roast should reach about 180 degrees and be fork-tender.
Rest the roast for 10-15 minutes before serving.
