Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, whisk together 3 tbsp maple syrup, 2 tbsp Dijon mustard, 2 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper to make the glaze.
  2. Step 2: Rub 1.5 lbs pork tenderloin with 2 tbsp olive oil and place on a baking sheet lined with foil. Brush the maple mustard glaze evenly over the pork.
  3. Step 3: Roast the pork in the preheated oven for 25-30 minutes, brushing with remaining glaze halfway through, until the internal temperature reaches 145°F.
  4. Step 4: While pork roasts, place 2 peeled and cubed medium sweet potatoes in a large pot and cover with water. Bring to a boil and cook for 15-18 minutes until tender when pierced with a fork.
  5. Step 5: Drain sweet potatoes and return to the pot. Add 2 tbsp unsalted butter, 1/4 cup milk, and 1/4 tsp ground cinnamon. Mash until smooth and creamy.
  6. Step 6: Remove pork from oven and let rest for 5 minutes before slicing. Serve sliced pork alongside the sweet potato mash.
