To make these potatoes, start by preheating your oven to 425 F.

Next, wash the potatoes and cut them in half.

Then, take your knife and "score" the potatoes by cutting diagonal lines alongside the cut-side of each potato.

Transfer the cut potatoes to a large bowl and add in the olive oil, parsley, garlic powder, sea salt, and black pepper. Toss until the potatoes are fully coated in the oil and seasonings.

Next, grate the parmigiano reggiano into a bowl and pour the melted butter on top. Mix them together until a thick paste forms.

Transfer the paste to a large baking dish and use a spoon or spatula to spread it out evenly across the bottom of the dish.

Then, transfer the potatoes to the baking dish and place them cut-side down, pressing them into the cheese mixture. Repeat until all of the potatoes are in the dish.

Finally, bake the potatoes for 25-26 minutes.

Once they're done, remove them from the oven and allow the potatoes to rest for 10 minutes, until the cheese hardens.

Then, use a spatula to remove the potatoes from the pan, serve, and enjoy!
