Start by bringing the roast to room temperature for 30 minutes.
Preheat oven to 400º F.
Mix seasonings together in a small bowl. Generously rub the seasoning into the roast.
Place roast fat side up on roasting pan equipped with a rack.
Roast uncovered for 15 minutes until a golden-brown crust forms.
Reduce the heat to 325 º F and continue to roast uncovered for about 1 and a half to 2 hours. This will vary depending on the size of your roast. Pork roast is done when a meat thermometer reaches an internal temperature of 160 degrees Fahrenheit for a well-done roast. For a more rare roast, a temperature of 145º F is a safe temperature.
Remove pan from oven and place on cutting board. Let rest for 10 minutes before slicing. This keeps all those tenderizing juices inside the roast.
you can safely cook pork to 140 degrees, but I don't like any pink in my pork so I cook to 160 degrees.
