  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 1 pound halved Brussels sprouts with 2 tablespoons olive oil, 1 teaspoon sea salt, and 1/2 teaspoon black pepper. Spread on a large rimmed baking sheet.
  2. Step 2: In the same bowl, mix 3 tablespoons olive oil, 1 teaspoon lemon zest, 2 tablespoons lemon juice, 4 minced garlic cloves, 1/2 teaspoon sea salt, 1/2 teaspoon black pepper, and 1 tablespoon fresh thyme leaves.
  3. Step 3: Add 6 bone-in, skin-on chicken thighs to the marinade and toss to coat thoroughly.
  4. Step 4: Nestle the chicken thighs skin-side up among the Brussels sprouts on the baking sheet.
  5. Step 5: Roast for 35-40 minutes, until the chicken skin is golden and crisp, and an internal temperature of 165°F is reached, while the Brussels sprouts are tender and caramelized.
