Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, combine 3 tbsp softened unsalted butter, 1 tbsp chopped fresh thyme, 1 tbsp chopped fresh rosemary, 3 minced garlic cloves, 1 tsp lemon zest, 1 tsp salt, and 1/2 tsp black pepper to make the herb butter.
  2. Step 2: Pat the 1.5 lb pork tenderloin dry and rub the herb butter all over the surface. Heat 1 tbsp olive oil in an ovenproof skillet over medium-high heat and sear the pork for 3-4 minutes per side until golden brown.
  3. Step 3: Transfer the skillet to the oven and roast the pork for 15-20 minutes until an internal temperature of 145°F is reached. Remove pork and let rest on a cutting board.
  4. Step 4: Place the skillet on the stove over medium heat, add 1/2 cup dry white wine, and scrape up browned bits, simmering until the sauce reduces by half and slightly thickens, about 3 minutes. Slice the pork and serve drizzled with the pan sauce.
