Instructions

  1. Step 1: Preheat oven to 400°F. Pat the pork tenderloin dry and season with 1/2 tsp salt and 1/4 tsp black pepper.
  2. Step 2: In a small bowl, mix 2 tbsp fresh rosemary, 1 tbsp fresh thyme, 3 minced garlic cloves, 1 tbsp Dijon mustard, and 2 tbsp olive oil to form a paste. Rub the paste evenly over the entire surface of the pork tenderloin.
  3. Step 3: Place the pork tenderloin in a ring mold (or shape it into a circle on a baking sheet) and wrap the herb paste around it. Surround the pork with 2 medium peeled and cut carrots, 2 medium peeled and cut parsnips, and 1 medium cut red onion wedges. Drizzle with any remaining herb paste and season with an additional pinch of salt and pepper.
  4. Step 4: Roast for 25-30 minutes, or until the internal temperature reaches 145°F, turning the vegetables halfway through. Let rest for 5 minutes before slicing and serving with the roasted vegetables.
