Preheat the oven to 400°F (200°C). Line a baking tray with parchment paper.
Slice the sweet potato into wedges, toss with olive oil, garlic powder, paprika, salt, and pepper.
Place the sweet potato wedges on the baking tray and roast for 25-30 minutes, turning halfway through.
While the sweet potatoes roast, pound the chicken breast slightly for even cooking.
Season the chicken with salt and pepper.
Prepare a breading station: in one bowl, beat the egg; in another, combine the panko breadcrumbs with a pinch of garlic powder, paprika, salt, and pepper.
Dip the chicken breast first in the egg wash, then coat evenly with the breadcrumb mixture.
Place the breaded chicken on a separate sheet or space on the baking tray once the wedges are partially roasted, and bake for an additional 20 minutes or until the chicken is cooked through and crispy.
Check that the chicken reaches an internal temperature of 165°F (74°C) before serving alongside the roasted sweet potato wedges.
