Cut the potatoes into cubes and boil them starting from cold water for about 10-15 minutes; they should soften but not fall apart.
Transfer them to a bowl and season with plenty of oil, plenty of breadcrumbs, salt, pepper, paprika, and Parmesan, then gently mix with a spatula so all the seasonings stick well.
Spread them out on a baking tray lined with parchment paper, well spaced apart, add another drizzle of oil on top, and cook in the oven or air fryer at 200 degrees for 15-20 minutes or until perfectly golden.
Perfect both in the oven and in the air fryer.
