Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Pat dry 2 lbs pork loin roast and season all over with 1 1/2 tsp salt and 1 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. Sear the pork loin on all sides for 3-4 minutes per side until golden brown.
  3. Step 3: In a small bowl, whisk together 1/4 cup Dijon mustard, 2 tbsp honey, 1 tbsp apple cider vinegar, 3 minced garlic cloves, and 1 tbsp chopped fresh rosemary until smooth.
  4. Step 4: Brush the mustard glaze all over the seared pork loin, then transfer the skillet to the preheated oven.
  5. Step 5: Roast for 25-30 minutes, basting with additional glaze halfway through, until the internal temperature reaches 145°F.
  6. Step 6: Remove from oven and let rest for 10 minutes before slicing to retain juices and enhance flavor.
