What is Pork Sirloin Roast?
Pork sirloin roast comes from the hip muscle of the pig. It’s a relatively lean cut that is oval shaped with a tapered end. Since it doesn’t contain as much fat or connective tissue as shoulder or butt roast, pork sirloin cooks up tender and juicy in a shorter amount of time.
When selecting a pork sirloin at the store, choose a 2-3 lb boneless roast for 4-6 servings. Pick one with nice marbling throughout for the most flavor and moisture.
