Boil potatoes until tender and allow to cool until they’re cool enough to handle.Preheat oven to 425.Once cool enough to handle, lay out your tea towel and line with wax paper. Line half of the wax paper with potatoes, leaving 1 inch between potatoes. Fold the tea towel in half, so the potatoes are fully covered with wax paper and the tea towel.Take your heavy pot and use it to pound down the potatoes – usually one heavy smack of the pot will work. The thinner you make the potatoes at this point, the crispier they’ll be.Transfer smashed potatoes to your sheet pan and drizzle both sides with olive oil. Top with sea salt and freshly cracked black pepper.Place in oven for 30 minutes, flipping once after 15 minutes. If you like your potatoes super crispy, feel free to leave them in for a couple of minutes extra.Serve hot and top with shredded cheese, sour cream, green onions, hot sauce, or any of your other favourite toppings.
