Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the spice rub:

• 1/2 cup light brown sugar, packed
• 3 tablespoons chili powder
• 2 teaspoons ground cumin
• 2 teaspoons paprika or smoked paprika
• 1/2 teaspoon garlic powder
• 1/4 teaspoon cayenne pepper (optional)

For the chicken and vegetables:

• 2 pounds sweet potatoes, peeled and diced into 1-inch chunks
• 4 tablespoons olive oil, divided
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 2 pounds boneless skinless chicken breasts
• 1 large red onion, cut into thick wedges
• 2 tablespoons fresh parsley or cilantro, chopped for garnish

Directions

1. Preheat your oven to 425°F. Line a large baking sheet with parchment paper or foil for easier cleanup.
2. Place the diced sweet potatoes on the baking sheet. Drizzle with 2 tablespoons olive oil and season with half the salt and pepper. Toss well to coat evenly.
3. Roast the sweet potatoes for 8 to 10 minutes while preparing the chicken.
4. In a medium bowl, combine the brown sugar, chili powder, cumin, paprika, garlic powder, and cayenne pepper. Stir until fully mixed.
5. Pound the chicken breasts lightly so they are an even thickness. This helps them cook evenly and stay juicy.
6. Rub the chicken generously with the spice mixture, coating both sides completely.
7. Remove the baking sheet from the oven. Push the sweet potatoes to the sides and place the chicken breasts in the center. Add the red onion wedges around the pan.
8. Drizzle the remaining olive oil over the onions and chicken if needed.
9. Return the sheet pan to the oven and bake for 18 to 22 minutes, or until the chicken reaches an internal temperature of 165°F.
10. Let the chicken rest for 5 minutes before slicing. Garnish with fresh parsley or cilantro and serve warm.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days.

To reheat in the microwave, warm individual portions for 1 to 2 minutes until heated through.

For the best texture, reheat in a 350°F oven for about 10 minutes. This helps the sweet potatoes stay slightly crisp and keeps the chicken juicy.

You can also freeze the cooked chicken and vegetables for up to 2 months. Thaw overnight in the refrigerator before reheating.
