Preheat oven to 400°F (200°C).
In a large bowl or the baking dish you'll use for roasting, combine the 2 pounds potato wedges, 3 crushed garlic cloves, 4 tablespoons extra virgin olive oil, 1/2 teaspoon salt, 1/2 teaspoon pepper, and the chopped leaves from the 2 rosemary sprigs (discard the stems). Toss until the potatoes are evenly coated.
Spread the potatoes in a single layer in the baking dish so they have some space between them for crisping.
Bake for 30 minutes.
Remove the dish from the oven and evenly sprinkle 3/4 cup grated low-fat Parmesan over the potatoes.
Return to the oven and bake an additional 15 minutes, or until the potatoes are tender, golden, and the cheese is melted and slightly crisp at the edges.
Remove from the oven, sprinkle with 1/4 cup finely chopped fresh parsley, and serve warm.
