Instructions

Step 1: Preheat oven to 425°F. In a large bowl, toss 2 medium peeled and cubed sweet potatoes with 1 tablespoon olive oil, 1 teaspoon Cajun seasoning, and 1/2 teaspoon salt until evenly coated. Spread on one half of a rimmed sheet pan.
Step 2: In the same bowl, mix 1.5 pounds boneless skinless chicken thighs with 2 tablespoons olive oil, remaining 1 tablespoon Cajun seasoning, 1 teaspoon garlic powder, 1 teaspoon smoked paprika, 1/2 teaspoon black pepper, and 1/2 teaspoon salt until well coated.
Step 3: Arrange the seasoned chicken thighs on the other half of the sheet pan next to the sweet potatoes. Roast for 20 minutes.
Step 4: After 20 minutes, add 12 ounces trimmed green beans tossed with 1 tablespoon olive oil and a pinch of salt to the sheet pan. Roast everything together for another 12-15 minutes until chicken reaches 165°F internal temperature and vegetables are tender with slightly crisp edges.
Step 5: Remove from oven and squeeze fresh lemon wedges over the chicken and vegetables before serving.
