Part 3/5:
After the initial 15 minutes, take a moment to admire how beautifully the potatoes have started to roast. They will begin to take on a delightful golden color, signaling that they are well on their way to becoming irresistibly crispy.
At this point, it's time to add the final flourish: sprinkle the grated cheese over your potatoes. The cheese will melt and contribute a delightful layer of flavor to the dish. Return the baking sheet to the oven for an additional 5-7 minutes, allowing the cheese to become golden and bubbly.
