In a roasting pan, let the roast sit at room temperature for 60 minutes.
Preheat the oven to 375F. Mix the spices together in a small bowl.
Rub the roast down with the seasonings, making sure the whole top is liberally covered.
Now, for the hard part. Let the roast sit in the oven for 1 hour. After 1 hour, turn off the oven completely. Let the roast sit in the oven for 3 hours. Do NOT open the oven door – you want the residual heat to continue cooking the meat. Remove the roast from the oven and cover with foil. Let it rest for 10 minutes additionally.
Slice the roast as thick as you’d like it. Serve! I had this with a side of broccoli with ranch and hot sauce.
