Preheat your oven to 350 degrees F.
In a small bowl, mix together melted butter, thyme, oregano, cayenne pepper, onion powder, garlic powder, paprika, black pepper, and salt.
Generously rub the roast with butter. Then, rub over the entire surface of the roast, making sure to cover all sides.
Place the roast on a roasting pan and put it in the preheated oven. Let it cook for two hours or until a meat thermometer reads 140 degrees F.
Once it's cooked, take the roast out of the oven and let it rest for 15 minutes before slicing and serving.
Slice the roast into thin slices and serve with your favorite sides.
