03Preheat oven to 400ºF. Line a 9×11 baking dish with nonstick foil or use regular foil and spray with cooking spray.
04Using tongs, transfer the pork loin to the prepared baking dish. Pour the marinade over the pork loin. Bake for 1 hour, turning pork loin every 20 minutes, or until internal temperature reaches 145-150ºF. Remove loin to serving plate, cover with foil, and let rest for 15-20 minutes while you finish the sauce.
05Empty the pan drippings into a small sauce pan and heat over medium heat. Combine the cornstarch with room temperature chicken broth and whisk until smooth. Add the broth to the boiling pan drippings and cook for a minute or two. Remove from heat.
06Slice pork loin and place on serving platter. Drizzle sauce over all before serving and place any extra sauce in an extra dish on the side. Garnish with sliced green onions if desired.
