Why this recipe works:


  • Slow-cooked at a low temperature: Cooking at 325°F for 4 hours allows the pork loin to tenderize slowly for melt-in-your-mouth results.
  • Dutch oven magic: The heavy, Dutch oven locks in moisture and circulates the heat evenly, creating the perfect cooking environment for juicy pork.
  • Flavor: Garlic, fennel, and onion add layers of savory goodness, while orange lends a subtle sweetness and citrus brightness to the dish.

Tips & Tricks

  • Room temperature – Let the prepared pork loin sit at room temperature for 30 minutes before placing it in the oven to ensure even cooking
  • Meat Thermometer – Check for an internal temperature between 145°F to 165°F.
  • Rest the Meat – After cooking, let the pork rest uncovered for 10 minutes before slicing; this keeps the juices locked in.
