Preheat oven to 180°C (350°F).
Thoroughly wash your white potatoes. Peeling is optional — if the skins are clean, I like to leave them on.
Chop each potato into quarters or eighths (depending on potato size).
Line a baking tray with baking paper and evenly spread out the chopped potatoes.
Bake for 20–25 minutes, or until the potatoes start to brown.
Remove from the oven and use a handheld masher to gently smash each piece.
Optional dressing: In a small bowl, mix olive oil, lemon juice, and salt. Drizzle the dressing over the smashed potatoes, and gently toss to coat.
Return the tray to the oven for another 5–10 minutes, or until you reach your desired crispiness.
Season with salt as per your taste.
Serve and enjoy!
