Instructions
1
Place a rack in the center of the oven and preheat the oven to 400. Line a large, rimmed baking sheet with foil.
2
Place the sweet potatoes in a large bowl. Drizzle with olive oil and sprinkle with salt and pepper. Toss to coat and then spread into a single layer on the baking sheet. Bake for 10 minutes.
3
Meanwhile, cut the chicken and vegetables and place in the same bowl. Drizzle with olive oil, and add the lemon juice and spices. Toss to coat.
4
Transfer the chicken and vegetables to the sheet pan with the sweet potatoes, spreading everything into an even layer.
5
Return to the sheet pan to the oven and bake for 15 to 20 additional minutes, stirring once halfway through, until the chicken is cooked through and no longer pink in the middle. Sprinkle with Parmesan.
