Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 1 lb halved Brussels sprouts and 6 whole peeled garlic cloves with 2 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper until evenly coated. Spread on a rimmed baking sheet in a single layer and roast for 20-25 minutes, stirring halfway through, until edges are crispy and golden.
  2. Step 2: While Brussels sprouts roast, pat dry 4 bone-in, skin-on chicken thighs and season both sides with 1/2 tsp sea salt, 1/4 tsp black pepper, and 1 tbsp chopped fresh thyme.
  3. Step 3: Heat remaining 1 tbsp olive oil in a large skillet over medium-high heat. Place chicken thighs skin-side down and sear for 6-7 minutes until skin is deep golden brown and crispy. Flip and cook for another 5 minutes.
  4. Step 4: Transfer skillet with chicken to the oven alongside Brussels sprouts and roast for an additional 10 minutes until internal temperature reaches 165°F and juices run clear. Remove from oven and let rest for 5 minutes before serving.
