This is a huge hit and a must try if you like pork. I'm not the biggest cranberry fan but this is delicious.
2 tablespoons olive oil, divided
1 pork tenderloin (about 1 lb.)
1/2 teaspoon coarse kosher salt
1/2 teaspoon freshly ground black pepper
1 small red onion, diced
2 cloves garlic, minced
1/2 cup reduced-sodium chicken broth
1/2 cup whole-berry cranberry sauce
2 teaspoons minced fresh rosemary
1 tablespoon balsamic vinegar
1. Preheat oven to 350°. In a large frying pan, heat 1 tbsp. oil over medium-high heat. Season pork with salt and pepper; brown lightly all over, about 5 minutes.
2. Transfer pork to a foil-lined 9- by 13-in. baking pan. Add remaining 1 tbsp. oil to frying pan, reduce heat to medium, and add onion. Cook, stirring, until softened, 3 minutes. Add garlic; cook 1 minute, then pour in chicken broth, cranberry sauce, rosemary, and vinegar. Cook 2 minutes.
3. Pour hot cranberry sauce over pork and bake, uncovered, until an instant-read thermometer inserted into meat registers 160°, about 20 minutes. Let pork rest 10 minutes, then slice and serve with sauce.
