Cook potatoes: Begin by bringing a large pot of water to a rolling boil and adding 1 tbsp of salt. Add the potatoes and cook until tender—small potatoes will take about 20 to 25 minutes, while medium ones will require around 30 minutes. It's perfectly fine if the skins burst during cooking. Alternatively, you can steam or microwave the potatoes if preferred.
Preheat your oven to 200°C/390°F (180°C fan-forced).
Steam dry: Once cooked, drain the potatoes and allow them to sit in the colander for approximately 5 minutes to dry off.
Smash: Arrange the potatoes on a baking tray, then use a large fork or potato masher to gently press them down, keeping them mostly intact. Thinner potatoes will be crispier, while thicker ones will have a fluffier interior—both textures are delightful. The more uneven the surface, the crunchier the outcome!
Steam dry again: Leave the smashed potatoes on the tray for another 5 minutes to steam dry, enhancing their crispiness.
Drizzle: Generously drizzle the melted butter over the potatoes, followed by the olive oil. Season with the sprinkling salt and black pepper.
Bake: Place the tray in the preheated oven and bake for 45 minutes for small potatoes and up to 55 minutes for medium ones, or until they reach a deep golden color and become irresistibly crispy. Avoid flipping them during baking.
Serve the potatoes hot, optionally garnished with finely chopped parsley for a touch of freshness and color. Enjoy!
