  • 1 (18.4 ounce) Garlic & Herb marinated pork tenderloin (such as one made by Smithfield; or see note below for a substitute)
  • 1 lb. baby red potatoes diced into small bite-sized pieces
  • 1 lb. carrots peeled and thinly sliced into bite-sized rounds (you can to make sure that your carrots and potatoes are chopped small enough so that they become tender by the time the pork is done cooking)
  • 1 onion coarsely chopped
  • 3 teaspoons minced garlic (I often use a squeeze bottle of pre-minced garlic from the produce section for a shortcut)
  • Salt and pepper to taste
  • 2 tablespoons olive oil
  • 2 sprigs fresh rosemary
  • 2 sprigs fresh thyme


  • Preheat oven to 425 degrees F.
  • Spray a large (about 9x13-inch) baking dish with cooking spray.
  • In a large zip-top bag, toss together potatoes, carrots, onion, garlic, salt and pepper, and olive oil until everything is completely coated.
  • Arrange vegetables in the bottom of the prepared dish. Place marinated pork on top. Tuck herbs among the vegetables.
  • Put dish in the oven (uncovered) and roast for 35-40 minutes, or until pork is cooked through (and thermometer reads 145 degrees F). Smaller tenderloins may need less time, so check the pork at the 25 or 30-minute mark.
  • Remove herbs from dish. Allow pork to rest for 5-10 minutes before slicing and serving. Garnish with fresh herbs, if desired.
