Preheat oven to 425 degrees F.
Wash potatoes and cut them in half. Then, take a sharp knife and score them into a diamond shape.
Transfer the potatoes to a large bowl and toss with olive oil, parsley, garlic powder and salt. Set aside.
Next, grate the parmigiano reggiano cheese. Pour melted butter on top and mix until you get a thick paste.
Transfer the mixture to a large baking dish and spread into an even layer.
Take each potato half and press it into the cheese, cut side down. Repeat until all potatoes are in the dish.
Bake for 25-26 minutes.
Remove from the oven. Let the potatoes rest for 10 minutes so the cheese hardens and then take a spatula and remove from the pan.
Break into pieces and enjoy!
