Place potatoes in a large bowl, add cold water and ice cubes to cover. Let stand for 15 minutes.

Preheat the oven to 425 F degrees. Spray a nonstick baking sheet with vegetable oil cooking spray and set aside.

Drain the potatoes in a colander. Spread on a double layer of paper towels. Cover with a second layer of paper towels. Press down on the towels to dry the potatoes. Transfer the wedges to a clean large bowl. Sprinkle with oil, pepper, and salt, toss gently to combine. Arrange seasoned potatoes in a single layer on the prepared baking sheet.

Bake the potatoes for 20 minutes. Using a spatula, turn the potatoes and sprinkle with minced garlic. Bake another 20 minutes until the potatoes are golden. You may want to turn your baking sheet once in the oven for more even browning about 30 minutes into the roasting process.
