Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 12 oz halved Brussels sprouts and 1 medium cubed sweet potato with 2 tbsp avocado oil, 1/2 tsp sea salt, and 1/4 tsp black pepper until evenly coated. Spread on a rimmed baking sheet and roast for 25-30 minutes, stirring halfway, until tender and caramelized.
  2. Step 2: Meanwhile, pat dry 4 bone-in, skin-on chicken thighs with paper towels. Season both sides with 1 tsp garlic powder, 1 tsp smoked paprika, remaining 1/2 tsp sea salt, and 1/4 tsp black pepper.
  3. Step 3: Heat 1 tbsp avocado oil in a large skillet over medium-high heat until shimmering. Place chicken thighs skin-side down and sear for 6-7 minutes until skin is golden brown and crispy. Flip and cook for another 6-7 minutes until internal temperature reaches 165°F and juices run clear.
  4. Step 4: Remove chicken from skillet and let rest for 5 minutes. Sprinkle roasted Brussels sprouts and sweet potatoes with 1 tbsp chopped fresh thyme leaves for a fragrant finish. Serve chicken alongside the roasted vegetables.
