Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper to ensure the fries don't stick.
Wash and dry the russet potato thoroughly, then slice it into 1/2-inch thick wedges; slice the chicken breast into strips of a similar size.
In a large mixing bowl, whisk together the extra virgin olive oil, garlic powder, sea salt, and black pepper.
Add the potato wedges and chicken strips to the bowl, tossing vigorously until every piece is evenly coated in the oil and spice mixture.
Arrange the potatoes and chicken in a single layer on the baking sheet, leaving space between each piece to allow for maximum air circulation and crispiness.
Bake for 20 to 25 minutes, flipping the pieces halfway through the cooking time, until the potatoes are golden brown and the chicken is fully cooked.
Remove from the oven and immediately sprinkle with the grated parmesan cheese and finely chopped fresh parsley while the heat can still melt the cheese slightly.
