Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 lb halved Brussels sprouts with 1 tbsp olive oil, 3 minced garlic cloves, 1/2 tsp sea salt, and 1/4 tsp black pepper. Spread on a rimmed baking sheet and roast for 20 minutes until tender and caramelized.
  2. Step 2: Meanwhile, pat dry 4 bone-in, skin-on chicken thighs and season both sides with 1 tsp sea salt, 1/2 tsp black pepper, and 1 tsp paprika.
  3. Step 3: Heat remaining 2 tbsp olive oil in a large cast-iron skillet over medium-high heat. Place chicken thighs skin-side down and sear without moving for 6-7 minutes until skin is deep golden and crisp.
  4. Step 4: Flip chicken thighs and add 1 tbsp fresh thyme leaves to the pan; cook for another 5-6 minutes until internal temperature reaches 165°F and juices run clear.
  5. Step 5: Remove chicken from heat and let rest for 5 minutes. Serve chicken thighs alongside the roasted Brussels sprouts, spooning any pan drippings over top.
