Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Pat chicken breasts dry with paper towels and season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper.
  2. Step 2: Whisk together 3 tbsp olive oil, lemon zest, lemon juice, minced garlic, and 1 tsp dried rosemary in a small bowl until emulsified.
  3. Step 3: Place chicken breasts on a large sheet pan, brush with half the lemon-herb mixture, then arrange carrots, parsnips, and sweet potatoes around the chicken.
  4. Step 4: Drizzle remaining lemon-herb mixture over vegetables, toss to coat evenly, and spread in a single layer.
  5. Step 5: Roast for 25-30 minutes, or until chicken reaches 165°F internal temperature and vegetables are tender with golden-brown edges.
