Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 lb halved Brussels sprouts with 2 tbsp olive oil, 1 tsp sea salt, and 1/2 tsp black pepper. Spread on a baking sheet and roast for 20-25 minutes, turning halfway until edges are golden brown and crisp.
  2. Step 2: In a medium saucepan, combine 4 chopped carrots with 1 cup water and 1/2 tsp sea salt. Bring to a boil, then reduce heat and simmer for 15 minutes until carrots are very tender.
  3. Step 3: While carrots cook, pat dry 4 bone-in chicken thighs and season both sides with 1/2 tsp sea salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat. Place chicken thighs skin-side down and sear for 6-7 minutes until skin is deep golden and crispy.
  4. Step 4: Flip chicken thighs and cook for another 5-6 minutes until internal temperature reaches 165°F. Remove from skillet and keep warm.
  5. Step 5: Drain carrots, reserving 1/4 cup cooking liquid. Transfer carrots to a blender, add 1 tbsp lemon juice, 3 minced garlic cloves, and 1 tsp chopped fresh thyme. Blend until puréed smooth, adding reserved liquid as needed to achieve creamy consistency.
  6. Step 6: Serve chicken thighs alongside roasted Brussels sprouts and a generous dollop of carrot purée.
