Ginger-Marinated Pork Tenderloin - PCOS-Friendly Recipe

Whisk together 2/3 cup broth, soy sauce, brown sugar, ketchup, ginger, garlic, and vinegar and pour into a large sealable plastic bag. Add tenderloin and seal bag, then marinate, chilled, turning bag over occasionally, 2 hours.

Bring tenderloin to room temperature, about 1 hour.

Put oven rack in middle position and preheat oven to 425 °F.

Pat tenderloin dry and reserve marinade. Heat oil in a 12-inch ovenproof skillet over moderately high heat until hot but not smoking, then brown tenderloin on all sides, turning with tongs, about 3 minutes total. Transfer skillet to oven and roast pork until thermometer inserted diagonally into center of meat registers 155 °F, 12 to 15 minutes. Transfer to a cutting board and let stand, loosely covered with foil, 10 minutes.

While meat is roasting, pour marinade through a fine-mesh sieve into a small saucepan and boil until reduced to about 1/3 cup, 10 to 15 minutes. Stir in remaining cup broth and bring sauce to a simmer. Serve slices of tenderloin with sauce.
