Add potato wedges to a bowl of ice water. Allow the potatoes to soak for 30 minutes. Drain potatoes and blot dry with paper towel.

Preheat oven to 450F. Coat baking sheet with cooking spray and set aside.

In a mixing bowl, whisk together oil, garlic powder and paprika, and salt. Add potatoes and toss until evenly coated. Arrange potatoes on prepared baking sheet.

Roast for 30 minutes or until the wedges are crispy and golden brown on the outside, and fork tender on the inside, flipping the wedges halfway through cooking.

Allow to cool slightly and sprinkle with fresh parsley and parmesan before serving.
