Most British kitchens have a drawer that contains takeout menus, extra batteries, and rubber bands that have lost their elasticity. A bag of McCain chips is probably kept in the freezer somewhere close to this drawer. That has been the situation for many years. The brand has evolved into something of an institution—not in the grand ceremonial sense, but in the more subdued, sincere sense that things become a part of daily life. You’re not motivated to grab McCain chips. They work, so you reach for them.
The appliance that sits on the counter next to the kettle has changed recently, at least in many homes. Over the past few years, air fryers have become genuinely common in the UK, and the question that always comes up almost immediately after opening one is: Can I cook my chips in this? For McCain Home Chips Straight Cut, the answer is a clear-cut yes, and the timing is faster than most people anticipate.

McCain suggests using a 2000W or 1700W air fryer to cook their Home Chips Straight Cut for about 15 minutes at 200°C. Switch to a 1400W model, which has less power and can last up to 20 minutes. These are the numbers McCain publishes based on the chip’s engineering, not estimates based on conjecture. An air fryer produces high, circulating heat, which is exactly what the coating is meant to crisp under. In contrast, the oven requires 24 to 26 minutes at 210°C with the fan. Twenty-six minutes as opposed to fifteen. Until someone is hungry on a Tuesday night, that gap seems insignificant.
People seem to underestimate the importance of the shake. The chips are redistributed so that the sides that were resting against the metal are exposed to the air by removing the basket and giving it a firm shake about halfway through the cooking time, say seven or eight minutes. It’s the difference between chips that are uniformly golden and chips that are pale on one side and slightly overdone on the other. It’s a small action that becomes almost automatic after you’ve done it twice. The shake is required. It’s the action.
It’s important to note that air fryer models differ more than their manufacturers would like to acknowledge. Depending on the age, location of the heating element, and size of the basket, two air fryers with a 2000W rating can operate quite differently. Although the 15-minute mark is a good place to start, it’s beneficial to start around the 12-minute mark. This is acknowledged in McCain’s own instructions, which state that cook times should be modified in accordance with model variations. A minute’s difference at high heat can be seen on a chip, so yours may operate hotter.
The Home Chips Straight Cut’s construction is what makes them particularly durable in an air fryer. McCain applies what it calls a special crunchy coating to a potato that has been chosen for its fluffy interior. In contrast to the slower ambient heat of an oven, that combination—dense coating, soft core—responds well to the quick air circulation of a fryer. When the timing is right, the outcome is something that actually looks like the chips you’d get with a pub fish supper. Though not the same, it’s close enough that it doesn’t matter.
Writing so much about a frozen chip seems a little odd. However, it also contains an element of honesty. Most nights, cooking at home is about feeding people something delicious with the time and tools you actually have, not about aspirations. McCain Home Chips are one of those products that reward a little attention to technique, and the air fryer has quietly emerged as one of the more beneficial tools in that equation. Heat the basket, cook at 200°C, shake halfway through, and remove after 15 minutes. Really, that’s the whole point. It consistently functions, which is not insignificant.
