Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a small bowl, combine 2 tsp paprika, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp cayenne pepper, 1 tsp dried thyme, 3/4 tsp salt, and 1/2 tsp black pepper to make the blackening spice blend.
  2. Step 2: Place 4 boneless skinless chicken breasts on a large rimmed baking sheet. Drizzle 1 tbsp olive oil over the chicken and rub evenly, then sprinkle the blackening spice blend over both sides of the chicken breasts.
  3. Step 3: In a large bowl, toss 2 medium peeled and cubed sweet potatoes and 1 lb halved Brussels sprouts with 3 tbsp olive oil, 3/4 tsp salt, and 1/2 tsp black pepper until evenly coated.
  4. Step 4: Spread the sweet potatoes and Brussels sprouts around the chicken on the baking sheet in a single layer.
  5. Step 5: Roast in the preheated oven for 25-30 minutes, flipping the vegetables halfway through, until the chicken reaches an internal temperature of 165°F and the vegetables are tender and caramelized at the edges.
  6. Step 6: Remove from oven and let chicken rest 5 minutes before serving alongside the roasted vegetables.
