Full Recipe:
-
3 lb / 1.5 kg high-starch potatoes (e.g., Russet or Maris Piper)
-
2/3 cup / 165 ml peanut oil (or safflower, rice bran, sunflower, corn oil)
-
2 tbsp semolina (or polenta as a substitute)
-
2 tsp salt (3 tsp if you prefer more salt)
Directions:
-
Preheat your oven to its maximum temperature (e.g., 250°C/480°F).
-
Pour the oil into a metal or cast iron roasting pan and place it in the oven while it heats.
-
Peel and cut the potatoes into large chunks (about 6cm / 2.2 inches wide).
-
Bring a large pot of salted water to a boil, then parboil the potatoes for 10 minutes.
-
Drain the potatoes, return them to the pot, add semolina and salt. Clamp the lid on and shake vigorously 5 times to rough them up. Let sit with the lid on.
-
Check if the oil is hot enough by tossing in a small piece of potato — it should sizzle immediately.
-
Carefully pour the potatoes into the hot oil, toss gently to coat, and spread them out evenly.
-
Reduce oven temperature to 220°C/425°F and roast for 50 minutes to 1 hr 15 min, turning once midway.
-
Remove when golden brown with some browned edges. Serve immediately for peak crunchiness.
-
Optional: Reheat leftovers at 220°C/425°F for 15 minutes to regain crunch.

The Magic Behind Truly Crunchy Roast Potatoes
Roast potatoes are a timeless comfort food, beloved for their crispy exteriors and fluffy, steamy interiors. But achieving that elusive truly crunchy texture—crispy enough to crunch audibly when you bite in, yet soft and fluffy inside—is often easier said than done. This version of roast potatoes is a game-changer. Inspired by techniques made popular by Nigella Lawson and elevated with tweaks for accessibility and affordability, this recipe has been crafted with precision to produce the crispiest, most addictive roast potatoes imaginable.
Whether you’re preparing a Sunday roast, holiday dinner, or simply satisfying a craving, this method consistently delivers restaurant-quality potatoes at home—no deep-frying, no goose fat required. The real magic lies not in the complexity, but in the attention to technique: high-heat roasting, parboiling, semolina dusting, and oil selection all work in harmony to transform humble potatoes into golden, crunchy gems.
Why Technique Matters More Than Fancy Ingredients
While some recipes rely on expensive fats like goose or duck fat for flavor and crunch, this approach proves that the how is often more important than the what. The steps used here optimize texture through method, not cost.
Parboiling the potatoes partially cooks them and helps to soften the outer layer. When shaken in the pot after draining, their surfaces become roughed up, forming crevices and cracks. These imperfect surfaces are precisely what allow fat to cling during roasting, ultimately creating a deeply textured, crunchy crust.
The potatoes are also tossed in semolina, a coarse wheat flour traditionally used in pasta and bread-making. In this case, it acts as a secret weapon for crunch. It adheres to the roughened surfaces and crisps up beautifully in the oven, contributing to that signature crunch without overpowering the natural potato flavor.
The Importance of High-Temperature Oil
Oil isn’t just a lubricant in this recipe—it’s a key contributor to crust formation. The type of oil used matters immensely. You’ll need an oil with a high smoke point, like peanut, sunflower, safflower, or rice bran oil. These oils can be heated to very high temperatures without burning, which is essential for starting the Maillard reaction (the chemical browning process that makes food delicious) the moment the potatoes hit the pan.
Preheating the oil in a metal or cast iron pan before adding the potatoes is another crucial step. This ensures the potatoes begin crisping immediately upon contact, locking in moisture and developing that crackly, golden exterior. Skipping this step—or using a pan that doesn’t retain heat well—results in soggy, limp potatoes.
The Right Potato Makes All the Difference
One often overlooked component of successful roast potatoes is the variety of potato used. For truly crunchy roast potatoes, high-starch varieties are a must. These include Russet potatoes (common in the U.S.), Maris Piper (popular in the U.K.), or Sebago (used in Australia). High-starch potatoes have a dry, floury texture that absorbs fat well and becomes wonderfully fluffy on the inside when cooked. In contrast, waxy potatoes retain too much moisture and never reach that fluffy-crisp contrast.
Using the right type of potato in conjunction with the above methods practically guarantees a stellar result. You get a potato that’s deeply golden on the outside, shatteringly crisp, and tender on the inside—the kind that disappears fast from the serving dish.
How This Recipe Elevates Everyday Meals
These roast potatoes may sound extravagant, but they are the epitome of smart, practical cooking. The ingredients are affordable, and the technique is straightforward once you understand the “why” behind each step. What you get is a dish that feels indulgent, like something you’d expect from a high-end gastropub or a professional chef’s kitchen.
Because of their neutral yet deeply satisfying flavor, these potatoes pair effortlessly with a wide range of main courses. Serve them alongside roast lamb, grilled chicken, pork tenderloin, or even plant-based mains like lentil loaf or baked tofu. Their crunchy texture also makes them a great contrast to creamy sauces or braised vegetables.
Reheating and Leftovers: Still Crunchy!
Another reason this recipe stands out? The leftovers are just as good. Most roast potatoes lose their crispness once refrigerated, but these reheat beautifully. A quick stint in a hot oven—about 15 minutes at 220°C/425°F—restores most of the original crunch. That means you can confidently make a larger batch without worrying about sogginess the next day.
This quality also makes the dish an excellent candidate for meal prep or holiday spreads where cooking ahead is crucial. You can roast the potatoes in advance and reheat them right before serving, keeping your kitchen more manageable when guests arrive.
Expert Tips and Variations
Here are a few additional tips for perfecting the dish:
-
Use a heavy-duty pan: Lightweight pans lose heat quickly, which prevents the potatoes from crisping properly. A cast iron pan or heavy-duty metal baking tray is ideal.
-
Don’t overcrowd the pan: Give the potatoes space to crisp. Overcrowding traps steam and results in soft, pale potatoes.
-
Add aromatics sparingly: While garlic, rosemary, or thyme can add flavor, they burn easily at high temperatures. If using, add them during the last 15–20 minutes of roasting.
-
For an indulgent twist: Swap a portion of the neutral oil with duck fat for a deeper, savory flavor—especially if you have it on hand from another recipe.
