Preheat oven to 425°F (220°C).
Wash potatoes and cut them in half. Using a sharp knife, score them into a diamond shape.
Toss potatoes with olive oil, Italian seasoning, garlic powder, salt, and pepper. Set aside.
In a bowl, mix grated Parmesan with melted butter until a thick paste forms.
Spread the Parmesan mixture evenly onto a large baking dish.
Press each potato half, cut-side down, into the cheese mixture.
Bake for 25-26 minutes until golden and crispy.
Remove from the oven and let rest for 10 minutes to allow the cheese to harden.
Use a spatula if needed to remove from the pan, break into pieces, and enjoy!
