How Long to Roast Potatoes
Quick Scoop
There’s something deeply comforting about golden, crispy roast potatoes — the kind that crackle when you bite into them, giving way to a soft and fluffy center. But the tricky question everyone asks at holiday dinners or Sunday roasts is: how long should you roast potatoes? Let’s break it down precisely — with temperatures, timings, and a few chef’s tricks.
Perfect Roast Potato Timing
The general rule: roast potatoes for 45–60 minutes at 200°C (400°F). But timing depends on the type of potato, size of the chunks, and oven temperature. Here’s a quick reference table for clarity:
| Potato Type | Oven Temperature | Chunk Size | Cooking Time | Texture |
|---|---|---|---|---|
| Maris Piper / Yukon Gold | 200°C / 400°F | 2-inch cubes | 45-55 mins | Crispy outside, fluffy inside |
| Russet / King Edward | 220°C / 425°F | 2-inch halved pieces | 40-50 mins | Extra crisp |
| Red potatoes | 190°C / 375°F | 1-inch wedges | 35-45 mins | Firm and golden |
| New potatoes | 200°C / 400°F | Whole | 30-40 mins | Soft skin, tender flesh |
Step-by-Step Roasting Guide
- Preheat your oven — Set it to 200°C (fan-assisted ovens can go slightly lower).
- Parboil first (optional but worth it): Boil potatoes for about 8–10 minutes until just tender on the outside. Drain well.
- Rough up the edges: Shake them gently in the pot — this helps them crisp up in the oven.
- Use hot oil or fat: Preheat your roasting tray with oil, goose fat, or olive oil until shimmering before adding potatoes.
- Roast and flip: Roast uncovered for 20 minutes, then turn the potatoes for even browning. Continue another 25–35 minutes until golden.
Chef’s Tips for Ultimate Crispiness
- Sprinkle a pinch of semolina or cornmeal after parboiling for extra crunch.
- Choose high-starch potatoes — waxy ones tend to stay soft rather than crisp.
- Don’t overcrowd the pan. Potatoes need air circulation to roast, not steam.
- A touch of garlic, rosemary, or thyme in the oil elevates the aroma.
