4. Add Parmesan:
Sprinkle the grated Parmesan cheese over the seasoned potatoes and toss them gently again to ensure the cheese adheres to the potatoes.
5. Bake the Potatoes:
Spread the potatoes out in a single layer on the prepared baking sheet, cut side down for extra crispiness.
Bake for 25-30 minutes, or until the potatoes are golden brown and crispy on the edges. Flip the potatoes halfway through the baking time for even crisping.
