Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a small bowl, combine 3 tbsp avocado oil, 4 minced garlic cloves, 1 tbsp chopped fresh rosemary, 1 tsp sea salt, and 1/2 tsp black pepper.
  2. Step 2: Place 1.5 lbs pork tenderloin in the center of a large rimmed baking sheet. Toss 1 lb halved Brussels sprouts with half of the garlic-rosemary oil mixture and spread around the pork.
  3. Step 3: Brush the remaining garlic-rosemary oil evenly over the pork tenderloin. Roast everything in the oven for 25-30 minutes, turning Brussels sprouts halfway, until pork registers 145°F internal temperature and sprouts are tender with crispy edges.
  4. Step 4: Let the pork rest for 5 minutes before slicing. Serve slices alongside the roasted Brussels sprouts.
