Preheat your oven to 425°F (220°C).
Cut the potatoes in half and coat them well with oil.
Season the potatoes with freshly cracked black pepper and a pinch of sea salt.
Line a baking pan with parchment paper and place small pieces of butter along it.
Sprinkle the shredded sharp cheddar cheese (or parmesan) over the butter.
Arrange the potato halves, cut side down, on top of the butter and cheese.
Bake in the preheated oven for 30 to 40 minutes until they are crispy and fully cooked.
Carefully flip the potatoes and bake for a little longer if necessary to crisp the other side.
Add more cheese or your favorite toppings, serve, and enjoy.
