Ingredients

Instructions

  1. Step 1: Preheat the oven to 400°F. Toss 1 pound halved Brussels sprouts with 2 tablespoons olive oil, 4 thinly sliced garlic cloves, 1 teaspoon salt, 1/2 teaspoon black pepper, and 1 tablespoon chopped fresh thyme in a bowl until well coated. Spread on a rimmed baking sheet and roast for 20-25 minutes, stirring once halfway through, until tender and caramelized on the edges.
  2. Step 2: While the Brussels sprouts roast, pat dry 4 bone-in, skin-on chicken thighs and season both sides with 1/2 teaspoon salt and 1/2 teaspoon black pepper. Heat 1 tablespoon olive oil in a large ovenproof skillet over medium-high heat until shimmering.
  3. Step 3: Place the chicken thighs skin-side down in the skillet and sear without moving for 6-7 minutes until the skin is golden brown and crispy. Flip the thighs and sear the other side for 3 minutes.
  4. Step 4: Transfer the skillet to the oven and roast the chicken with the Brussels sprouts for an additional 10-12 minutes, or until an internal temperature of 165°F is reached. Remove from the oven and let rest for 5 minutes.
  5. Step 5: Serve the chicken thighs alongside the roasted Brussels sprouts with lemon wedges for squeezing over the top.
