Ingredients

Instructions

  1. Step 1: Preheat your oven to 425°F. In a large bowl, toss 2 cups peeled and cubed sweet potatoes with 1 tablespoon olive oil, 1/2 teaspoon salt, and 1/2 teaspoon black pepper until evenly coated.
  2. Step 2: Arrange the sweet potatoes on a large rimmed baking sheet in a single layer. Roast in the oven for 10 minutes to begin softening.
  3. Step 3: Meanwhile, in the same bowl, toss 1 pound halved Brussels sprouts with 1 tablespoon olive oil, 1/2 teaspoon salt, and 1/2 teaspoon black pepper.
  4. Step 4: Remove the baking sheet from the oven, add the Brussels sprouts around the sweet potatoes, and nestle 6 bone-in, skin-on chicken thighs on top.
  5. Step 5: Drizzle the remaining 1 tablespoon olive oil over the chicken thighs, then sprinkle 1 teaspoon garlic powder, 1 teaspoon smoked paprika, and 1 tablespoon chopped fresh thyme evenly over everything.
  6. Step 6: Roast for an additional 25-30 minutes, until the chicken skin is golden and crispy and the vegetables are tender when pierced with a fork.
  7. Step 7: Let rest for 5 minutes before serving. Enjoy the savory chicken combined with sweet and earthy vegetables.
