Preheat oven to 450º F.

Step 2

Add pork sirloin to a medium Dutch oven. Mix together olive oil, rosemary and garlic and rub onto the pork sirloin.

Step 3

Place the pork into the oven and cook uncovered for 30 minutes. Remove from oven, reduce temperature to 250º F, pour in chicken stock or other preferred liquid, cover and cook approximately 25 to 30 minutes per pound and until the internal temperature registers 145º F, basting with the pan liquids every 30 minutes.
