Instructions

  1. Mix all marinade ingredients together and, using a cooking syringe, inject into the tenderloin until plump and evenly full.
  2. Sprinkle the outside of the tenderloin with a generous amount of Zatarain’s Creole Seasoning, at least 3-4 tablespoons.
  3. In a skillet, slightly brown all sides of the tenderloin and finish in the oven at 375°, to your preferred doneness (see below). I like mine to reach an internal temperature of 130° and then take out of the oven.
  4. Let sit at least 10 minutes before cutting to let the meat and juices rest.
  5. Cover in more melted butter and fresh chopped basil, oregano and/or garlic!
