Put your rack right in the middle of the oven and warm it up to 425°F. Grab a baking sheet but don't line it with anything.

Take a potato and put it between two sticks or skewers. Make thin cuts down the potato about ⅛ inch apart, stopping when you hit the sticks so the bottom stays in one piece. Do the same with all potatoes.
03 -
Set your cut potatoes on the bare baking sheet. Take half your melted butter and brush it all over, making sure to get between the cuts. Sprinkle salt and pepper over everything.
04 -
Pop them in the oven for 30 minutes. When time's up, carefully pull the slices apart a bit with a knife.
05 -
Brush on the leftover melted butter. Stick them back in for another 30-35 minutes until they're crunchy outside but soft inside. Remember bigger potatoes might need more time.
06 -
Eat them while they're hot. Add more salt and pepper if you want.
