Preheat oven to 425F
Wash and scrub potatoes well, cut into long wedges, 8 per potato
Place potatoes into a large bowl, add olive oil and chopped garlic, toss to combine
Combine the dry ingredients: salt, rosemary, 1 teaspoon of pepper and cornstarch to a separate bowl and mix well
Add 1/3 of the dry ingredients to the potatoes and toss to combine, repeat adding dry ingredients two more times to ensure an equal distribution on the potatoes
Lay the potatoes in a single layer on a lined baking sheet, (silicon baking sheets works great for this)
Bake for 20 minutes, turn potatoes over, bake another 20-25 minutes,
Depending on how evenly you wedges are cut, some thinner wedges will bake faster than others, remove then faster baking ones if needed and return undercooked ones to the oven.
In a bowl, combine parmesan cheese, parsley and 1 teaspoon of black pepper
When fries come out of the oven, place them in a serving dish, add cheese mixture, and give them a gentle toss
