Wash and scrub the potatoes to get any dirt off. I like to also run the water over them in a colander.
Preheat oven to 450 degrees.
Heat a stock pot with water and bring to a boil. Then add the potatoes and cook until they're soft enough to spear with a fork. This should take 15- 20 minutes.
While the potatoes cook, mix together the extra virgin olive oil, garlic, rosemary, salt and pepper and parsley.
Drain the potatoes and spread them out on a ton stick baking sheet. Smash them until they are somewhat flattened. I use a measuring cup to do this. You want them 1/3 inch thick or so.
Spoon the olive oil mix over each individual potato.
Bake for 20 minutes or until they edges are crunchy! Season to taste with additional salt and pepper.
If you decided to add the butter, drizzle it over the potatoes right before serving. Serve with fresh parsley and top with the pine nuts.
