Instructions

  1. Step 1: In a bowl, combine 3 tbsp extra virgin olive oil, 1 tsp lemon zest, 2 tbsp lemon juice, 3 minced garlic cloves, and 1 tbsp finely chopped fresh rosemary. Add 4 bone-in chicken thighs and coat well. Marinate for 20 minutes at room temperature.
  2. Step 2: Meanwhile, peel and chop 3 medium carrots and 2 medium parsnips into 1-inch pieces. Place in a pot of salted water and bring to a boil. Cook for 20 minutes until vegetables are tender.
  3. Step 3: Preheat grill or grill pan to medium-high heat. Grill chicken thighs skin-side down for 6-7 minutes until skin is crisp and golden, then flip and grill 5-6 minutes more until internal temperature reaches 165°F.
  4. Step 4: Drain cooked carrots and parsnips. Mash with a potato masher or fork until smooth. Season with 1/2 tsp sea salt and 1/2 tsp black pepper. Add a drizzle of olive oil if desired for creaminess.
  5. Step 5: Plate grilled chicken thighs alongside the root vegetable mash. Garnish with remaining rosemary sprigs for aroma and serve immediately.
