Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 2 medium peeled and cubed sweet potatoes with 1 1/2 tbsp olive oil, 2 minced garlic cloves, 1/2 tsp kosher salt, and 1/2 tsp black pepper.
  2. Step 2: In another bowl, toss 3 cups halved Brussels sprouts with 1 1/2 tbsp olive oil, 3 minced garlic cloves, 1 tsp dried thyme, 1 tsp paprika, 1 tsp kosher salt, 1/2 tsp black pepper, and 1 tbsp chopped fresh rosemary.
  3. Step 3: Arrange 4 bone-in skin-on chicken thighs on a large rimmed baking sheet, skin side up. Season each with 1/2 tsp kosher salt and 1/2 tsp black pepper.
  4. Step 4: Surround chicken with sweet potatoes on one side of the pan and Brussels sprouts on the other. Roast in the preheated oven for 35-40 minutes until chicken skin is golden and crispy, vegetables are tender, and chicken registers 165°F internally.
  5. Step 5: Remove from oven and let rest for 5 minutes before serving.
