Preheat your oven to 400°F and line a large sheet pan with parchment paper for easy cleanup.
Peel and cut the sweet potato into 1-inch cubes and slice the chicken breast into similar bite-sized pieces.
In a large mixing bowl, whisk together the maple syrup, olive oil, garlic powder, smoked paprika, sea salt, and black pepper.
Add the sweet potato cubes, chicken pieces, and broccoli florets to the bowl and toss until every piece is thoroughly coated.
Spread the mixture in an even layer on the prepared baking sheet, ensuring the ingredients are not crowded so they roast properly.
Bake for 20 to 25 minutes, stirring halfway through, until the chicken is cooked through and the potatoes have a golden, caramelized exterior.
