I cook pork tenderloin most weeks. I keep it as simple as possible, trim the tenderloin, put it in an ovenproof dish with olive oil, fresh rosemary, salt and pepper, cover it with foil and put it in a 300 degree oven for about an hour.hen oil begins to ripple, place tenderloin in skillet with tongs, don't move it. Let sear for 2 minutes, turn over & sear 2 minutes. Repeat process until all sides are seared. Put skillet in oven & cook approximately 35-40 minutes, or 20 minutes per pound.
