Cut potatoes into wedges by cutting lengthwise in half then slice each half into 3 slices.
Place potatoes in a bowl of water with about 2 cups of ice cubes. Let them stand for 30 min then pat dry with paper towels.
Place 1/4 tsp salt, 1/4 tsp garlic powder, 1/2 tsp paprika and 1/4 tsp black pepper in to a large ziplock bag. Add potatoes and shake them together. Next add 1/4 cup of olive oil to the bag and toss until potatoes are coated.
Line baking sheet with foil. Place potatoes on the lined sheet and bake at 450˚F for 30-35 min until the potatoes are cooked through, browned and crispy.
