Ingredients

Instructions

  1. Step 1: Preheat the oven to 425°F. In a small bowl, whisk together 3 tbsp Dijon mustard, 2 tbsp honey, and 3 minced garlic cloves until smooth and fragrant.
  2. Step 2: Place 1.5 pounds pork tenderloin on a large rimmed sheet pan. Brush the mustard glaze evenly over the pork, coating all sides.
  3. Step 3: In a large bowl, toss 3 large peeled and chunked carrots, 2 medium peeled and chunked parsnips, and 4 small quartered red potatoes with 3 tbsp olive oil, 1 tbsp chopped fresh rosemary, 1.5 tsp salt, and 1 tsp black pepper until vegetables are well coated.
  4. Step 4: Arrange the vegetables around the pork tenderloin on the sheet pan in a single layer.
  5. Step 5: Roast in the preheated oven for 25-30 minutes, or until the pork reaches an internal temperature of 145°F and the vegetables are tender and caramelized at the edges.
  6. Step 6: Remove from oven and let the pork rest for 5 minutes before slicing. Serve the sliced pork with the roasted root vegetables.
