Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
Bring a large pot of salted water to a boil and cook potatoes until tender, for about 10-15 minutes. Drain and let cool slightly.
Spray the oil all over the baking sheet and transfer the potatoes. Use the bottom of the glass ( or jar or measuring cup) to smash each potato flat. Spray the oil over the surface and season with salt and pepper. Roast for 40-45 minutes until crispy and golden brown. Remove from the oven and let cool slightly.
