Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Pat chicken thighs dry; season with 1/4 tsp sea salt and 1/8 tsp black pepper. Cut sweet potatoes and parsnips into 1-inch cubes.
  2. Step 2: In a large bowl, toss vegetables with 1 tbsp olive oil, 1/2 tsp rosemary, 1/4 tsp sea salt, and 1/8 tsp black pepper until evenly coated. Spread in a single layer on a sheet pan.
  3. Step 3: Place chicken thighs on top of vegetables. Drizzle with remaining 1 tbsp olive oil and sprinkle with remaining 1/2 tsp rosemary. Roast for 30-35 minutes until chicken is cooked through (165°F/74°C internal) and vegetables are caramelized at the edges.
