There’s nothing quite like the satisfying crunch of a perfectly roasted potato – golden and crispy on the outside, fluffy and tender on the inside. After years of testing and tweaking, I’ve mastered the art of creating what I confidently call the best crispy roast potatoes ever. Today, I’m sharing my foolproof method that combines science-backed techniques with home cooking wisdom.
The Science Behind Perfect Roast Potatoes
Before diving into the recipe, let’s understand why certain steps are crucial for achieving potato perfection. The key lies in understanding the starch structure and how it reacts to different cooking methods. When you parboil potatoes before roasting, you’re actually creating a roughed-up exterior that will become magnificently crispy in the oven. Meanwhile, the interior starts its cooking process, ensuring that perfect fluffy center we’re all after.

Questions & Answers
Q: Can I make these ahead of time?
A: While they’re best served fresh, you can parboil the potatoes up to a day ahead. Store them in an airtight container in the fridge after they’re completely cool. Continue with the roasting process when needed.
Q: Why do you start with cold water for parboiling?
A: Starting with cold water ensures even cooking from the inside out. Hot water can cook the outside too quickly while leaving the center undercooked.
Q: Can I use olive oil instead of duck fat?
A: Yes, though the results won’t be quite the same. If using olive oil, choose one with a high smoke point and expect slightly less crispy results.
Q: How do I know when they’re perfectly done?
A: Look for a golden-brown color, listen for a hollow sound when tapped with tongs, and test one – it should be crispy outside and fluffy inside.
Q: Why do my potatoes sometimes turn out soggy?
A: Soggy potatoes usually result from overcrowding the pan or insufficient drying after parboiling. Ensure potatoes are well-spaced and thoroughly dried before roasting.
