Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). In a small bowl, combine 1 tbsp chopped rosemary, 1 tbsp chopped thyme, 3 minced garlic cloves, 1 tsp salt, 1/2 tsp black pepper, and 2 tbsp olive oil to create an herb rub.
  2. Step 2: Pat dry 1 lb pork tenderloin and rub the herb mixture evenly all over the meat.
  3. Step 3: Toss 3 peeled and chopped carrots, 2 peeled and chopped parsnips, and 4 quartered red potatoes in 1 tbsp olive oil and a pinch of salt and pepper.
  4. Step 4: Place the pork tenderloin on a roasting pan and surround with the seasoned root vegetables. Roast in the oven for 25-30 minutes until pork reaches an internal temperature of 145°F (63°C) and vegetables are tender and caramelized.
  5. Step 5: Remove from oven, let pork rest for 5 minutes before slicing. Serve pork slices alongside roasted vegetables for a warming, balanced meal.
