Ingredients

  • 3-4 pound boneless pork loin roast (not a tenderloin), tied
  • 2 Tablespoons Extra Virgin Olive Oil, divided
  • 2-3 cloves fresh garlic, minced
  • 2 Tablespoons Fresh rosemary, chopped (or 1 Tbsp dried)
  • 2 Tablespoons fresh thyme, chopped (or 1 Tbsp dried)
  • 1 Tablespoon fresh oregano, chopped (or 1 tsp dried)
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • 1 teaspoon black pepper

Instructions

  • TIP: About 30 minutes before cooking take the pork out of the refrigerator. This will ensure even cooking.
    Preheat oven to 375° F
  • In a small bowl prepare the herb coating paste by combining 1 Tablespoon of olive oil, garlic, rosemary, thyme, oregano, onion powder, salt, and pepper. Set aside.
  • Prepare the pork by rinsing and patting it dry with paper towels.
    "Score" pork roast by creating shallow diagonal lines making a diamond pattern on the surface. Scoring the meat helps ensure even cooking as well as helping the herbs and spices settle into the pork for a more flavorful end result.
  • Pat the roast all over with the herb paste.
  • Heat a large oven-proof heavy-bottom skillet, cast iron skillet, or Dutch oven over medium heat. Add and heat the remaining 1 Tablespoon of olive oil until shimmering.
  • Add the pork and sear it on all sides until golden brown (including the ends). This should take about 2 minutes on each side.
  • Place the pork in the oven and cook, uncovered, until the pork reaches an internal temperature of 150˚F. (If you don't have a thermometer plan on about 20-22 minutes per pound of pork).
  • Remove from the oven and place on a cutting board, loosely tented with aluminum foil, for 10 minutes to allow all of the juices to redistribute in the meat.
  • Slice and serve.
    For added flavor spoon the pan juices that have accumulated in the pan over the pork

For Slow Cooker / Crock Pot Pork Roast

  • Prepare meat and herb blend as instructed above. Sear meat in a pan and then place fat cap side up in a slow cooker.
    Add ¼ cup water (or broth) and cook on low for 4-6 hours (actual time depends on the size of roast), or to internal temperature of 150°F.
    Remove and rest for 10 minutes before slicing.

Notes

  • If you don't have a cooking thermometer, a good rule of thumb, is to cook a pork loin roast for 20-22 minutes per pound at 350˚ F (177˚ C).
  • The internal temperature should be at least 145˚F (63˚ C)
  • Pork can become dry if overcooked. Here is a general chart:
  • Medium-Rare = 145-150˚ - lightly pink inside and still moist
  • Medium = 150-155˚ – inside will be a little pink and moist
  • Medium-Well = 155-160˚-  no pink color remaining and not much moisture
  • Well Done = 160-165˚overall brown, dry inside (overcooked - please don't!)
