Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Pat dry 1 lb pork tenderloin and season all over with 1 teaspoon sea salt and 1/2 teaspoon black pepper.
  2. Step 2: In a small bowl, mix 3 tablespoons Dijon mustard, 3 minced garlic cloves, 1 tablespoon fresh thyme leaves, and 1 tablespoon chopped fresh rosemary.
  3. Step 3: Spread the mustard-herb mixture evenly over the pork tenderloin. Heat 2 tablespoons olive oil in a large oven-safe skillet over medium-high heat. Sear the pork on all sides for 2 minutes each until golden brown.
  4. Step 4: Transfer the skillet to the preheated oven and roast the pork for 15-18 minutes until the internal temperature reaches 145°F (63°C).
  5. Step 5: Remove from oven, tent with foil, and rest for 5 minutes before slicing. Serve with roasted vegetables or a fresh salad.
