Instructions

  1. Step 1: Preheat oven to 400°F. Pat dry 1 lb pork tenderloin and season all over with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: In a small bowl, combine 1/4 cup chopped fresh parsley, 1 tbsp fresh thyme leaves, 2 minced garlic cloves, and 1/2 cup panko breadcrumbs.
  3. Step 3: Brush half the pork tenderloin lengthwise with 3 tbsp Dijon mustard, then press the herb and breadcrumb mixture onto the mustard-coated half to form a crust.
  4. Step 4: Heat 2 tbsp olive oil in an ovenproof skillet over medium-high heat. Sear the pork tenderloin on all sides, about 2 minutes per side, until golden brown.
  5. Step 5: Transfer skillet to the oven and roast the pork for 15 minutes, or until internal temperature reaches 145°F.
  6. Step 6: Remove pork from skillet and rest on a cutting board. Place skillet back on stove over medium heat, add 1/2 cup chicken broth and scrape up browned bits, simmer 3 minutes.
  7. Step 7: Stir in 1 tbsp butter until melted and sauce thickens slightly. Slice pork and drizzle with pan sauce before serving.
