Ingredients

• 6 pieces bone-in, skin-on chicken thighs
• 4 medium, peeled and cut into 1-inch chunks carrots
• 3 medium, peeled and cut into 1-inch chunks parsnips
• 1 large, cut into wedges red onion
• 6, minced garlic cloves
• 4 fresh thyme sprigs
• 3 tablespoons extra virgin olive oil
• 1 1/2 teaspoons sea salt
• 1 teaspoon black pepper
• 1 tablespoon lemon juice

Instructions

1. Step 1: Preheat oven to 425°F. In a large bowl, toss 4 peeled and chunked carrots, 3 peeled and chunked parsnips, and 1 large cut red onion with 2 tablespoons extra virgin olive oil, 1 teaspoon sea salt, and 1/2 teaspoon black pepper until evenly coated.
2. Step 2: Spread the vegetables evenly on a large rimmed baking sheet. Arrange 6 bone-in, skin-on chicken thighs on top of the vegetables. Drizzle the chicken with the remaining 1 tablespoon olive oil and sprinkle with 1/2 teaspoon sea salt, 1/2 teaspoon black pepper, and 6 minced garlic cloves. Nestle 4 fresh thyme sprigs among the chicken and vegetables.
3. Step 3: Roast everything in the preheated oven for 35-40 minutes, until the chicken skin is golden and crisp and an instant-read thermometer inserted into the thickest part reads 165°F. Stir the vegetables halfway through roasting for even caramelization.
4. Step 4: Remove the pan from the oven and drizzle 1 tablespoon fresh lemon juice over the chicken and vegetables. Let rest for 5 minutes before serving, allowing flavors to meld and juices to redistribute.
