Preheat your oven to 425°F and line a large rimmed baking sheet with parchment paper to prevent sticking.
Wash and scrub the Russet potato, then slice it into half-inch thick wedges.
Cut the chicken breast into long strips, roughly the same thickness as the potato wedges to ensure even cooking.
In a large mixing bowl, combine the potato wedges and chicken strips with the olive oil, garlic powder, sea salt, and black pepper.
Toss everything thoroughly until the potatoes and chicken are well-coated in the oil and seasonings.
Spread the mixture onto the prepared baking sheet in a single layer, making sure the pieces are not touching to allow for maximum crispiness.
Bake for 20 to 25 minutes, flipping the potatoes and chicken halfway through the cooking time.
Remove the pan from the oven once the potatoes are golden and the chicken is cooked through.
Immediately sprinkle the hot fries and chicken with the grated parmesan cheese and dried parsley.
Let rest for 2 minutes before serving to allow the cheese to adhere to the warm crust.
