Ingredients
- 400 g potatoes (Maris Piper, Yukon Gold, or any floury potato)
- 3 tbsp olive oil (or duck fat / goose fat if you have it)
- 1 tsp salt
- 1/2 tsp black pepper
- 2 sprigs fresh rosemary (optional)
- 2 cloves garlic, whole and lightly crushed (optional)
Instructions
1. Preheat
- Preheat oven to 220°C (425°F).
- Pour the olive oil (or fat) into a roasting tray and place it in the oven to get hot.
2. Prep the potatoes
- Peel the potatoes (or leave skins on if you prefer).
- Cut into even-sized pieces — quarters or eighths depending on size. Aim for golf-ball sized chunks.
- Place in a pot of cold salted water.
- Bring to a boil and simmer for 5 minutes — just to parboil, not fully cook.
- Drain well in a colander.
3. Rough up the edges
- Give the potatoes a gentle shake in the colander to rough up the surfaces.
- The fluffy, roughened edges are what become crispy in the oven.
- Sprinkle with salt and pepper and toss.
4. Roast
- Carefully remove the hot tray from the oven — the oil should be shimmering.
- Add the potatoes to the hot oil. They should sizzle on contact.
- Turn each piece to coat in oil on all sides.
- Spread in a single layer, don’t crowd.
- Roast for 30–35 minutes, turning once halfway through.
- Add the rosemary and garlic for the last 10 minutes.
- They’re done when deep golden and crispy outside, fluffy inside.
5. Serve
- Remove from the oven.
- Drain briefly on kitchen paper if needed.
- Serve immediately — they lose crispiness as they sit.
Tips
- The secret is rough edges. Shaking the parboiled potatoes in the colander creates a fluffy surface that crisps up beautifully. Don’t skip this.
- Hot fat is essential. Putting potatoes into cold oil = soggy. Putting them into shimmering hot oil = crispy.
- Parboiling matters. It pre-cooks the inside so you get fluffy centers while the outside crisps. Raw potatoes in the oven take longer and don’t fluff up as well.
- Duck fat is next level. If you ever see it at the shops, try it once. It’s a game-changer.

Result
Golden, crunchy-on-the-outside, fluffy-on-the-inside roast potatoes with a hint of rosemary and garlic. The ultimate side dish — crispy potatoes done right.
