Preheat your oven to 425°F (220°C). This high temperature will help achieve that perfect crispiness.
Wash and scrub the potatoes thoroughly to remove any dirt. Slice each potato into wedges, aiming for uniform sizes to ensure even cooking.
In a large mixing bowl, combine the potato wedges with the crushed garlic, olive oil, salt, pepper, and chopped rosemary. Toss everything together until the potatoes are well coated.
Spread the seasoned potato wedges in a single layer on the baking sheet, ensuring they are not overcrowded. This allows for better air circulation and crispiness.
Bake the wedges in the preheated oven for about 25-30 minutes, flipping them halfway through. You’ll want them to be golden brown and crispy.
Once the wedges are done, take them out of the oven and immediately sprinkle the grated Parmesan cheese on top. Let it melt slightly and then garnish with fresh parsley.
Serve your Crispy Oven Potato Wedges hot and enjoy them as a side dish or a delicious snack!
