Baked smashed potatoes

It's been a while since I updated my recipes. Ages ago, when potatoes were new, I made some smashed potatoes, inspired by this.

Basically just take some boiled potatoes (I don't remember if I used warm or cold ones, either should work?), put in a baking tin and squash with the back of a big wooden spoon. Then drizzle with olive oil, sprinkle with salt and pepper, and put in the oven at 200C for about 30 min / until golden and crispy around the edges.
