Boil the potatoes with their skins on. Cut them in half. I left the skins on because I used baby potatoes.
Place some olive oil and grated cheese on parchment paper.
Place a half-boiled potato on the parchment, and gently press down with the bottom of a cup.
Sprinkle with salt, pepper, chili flakes, more olive oil, and additional cheese.
Bake in a preheated oven at 200 degrees Celsius (with fan) for 22 minutes until golden brown.
Enjoy with sour cream sauce!
