Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, combine 3 tbsp olive oil, zest and juice of 1 large lemon, 4 minced garlic cloves, 1 tbsp fresh thyme leaves, 1 1/2 tsp sea salt, and 1 tsp black pepper; whisk until well blended.
  2. Step 2: Add 6 bone-in chicken thighs to the bowl and toss to coat evenly with the lemon-garlic marinade. Let sit while preparing vegetables.
  3. Step 3: On a large rimmed baking sheet, spread 3 peeled and chopped carrots, 2 peeled and chopped parsnips, and 1 medium red onion cut into wedges; drizzle with a little olive oil and sprinkle with a pinch of salt.
  4. Step 4: Nestle the marinated chicken thighs skin-side up among the root vegetables on the baking sheet.
  5. Step 5: Roast in the preheated oven for 35-40 minutes, until chicken skin is golden and crisp and internal temperature reaches 165°F, and vegetables are tender when pierced with a fork.
