Anyone who has tried a full roast dinner knows exactly what it’s like to be under pressure on a Sunday afternoon. The gravy is thickening too quickly, the Yorkshire puddings are in danger of collapsing, the chicken needs to be basted, and the roast potatoes are patiently waiting in the back of the freezer. Aunt Bessie’s has subtly emerged as the solution to that pressure for a generation of British home cooks. However, a new query has recently surfaced in kitchens across the nation: is it possible to cook Aunt Bessie’s roast potatoes in an air fryer?
In a nutshell, the answer is yes. The slightly more intriguing response is that they might turn out better than they do in the oven.

By now, air fryers are far from novel. It’s easy to understand why what began as a device gathering dust on worktops has evolved into a true mainstay in British cooking. These machines’ forced hot-air circulation produces a type of intense, dry heat that works wonders for frozen goods, especially those with a fat coating, which is almost always present in frozen roast potatoes. Before freezing, Aunt Bessie’s roasties are pre-coated in oil, and once the air fryer starts up, that fat becomes the source of crispiness.
The process is quite simple, according to Aunt Bessie’s own instructions. After preheating the air fryer to 200°C for about three and a half minutes, load the basket with no more than 250g of frozen potatoes, or about two portions, and cook for 20 to 22 minutes. Halfway through, give the basket a shake. That’s pretty much it. The 250g cap may irritate those preparing food for a full table, but there’s a reason for this restriction: packing the basket too full prevents airflow, which eliminates crispness. If you stack them too high, the result will resemble steamed potatoes, which is not what anyone wants on Sunday.
The consistency of the results is noteworthy. For the past few years, home cooks from a variety of online communities have been reporting back, and the results are remarkably consistent: golden on the outside, fluffy on the inside, and finished more quickly than an oven could. A Facebook community recommended 15 minutes at 200°C and deemed it adequate. 15 minutes at 180°C is recommended by recipe websites such as Recipe This. The official recommendation is 20 to 22 minutes. There’s a feeling that the precise timing is largely dependent on the brand of air fryer you’re using because different brands have different wattage and basket designs. The most honest advice anyone can give is probably to check them after 15 minutes and judge them by color.
It’s difficult to ignore the timing’s allure. At a much higher temperature, oven-roasted frozen potatoes require 25 to 30 minutes, meaning the oven must run and use energy for almost 30 minutes. In contrast, the air fryer takes less than four minutes to preheat and completes the task in about the same amount of time, frequently producing a crispier outcome. Having the potatoes handled separately in the air fryer frees up shelf space for everything else during busier cooking sessions when oven space is actually contested. When you’re juggling several dishes at once, that’s not a minor issue.
For many years, Aunt Bessie’s has held a special place in British freezer culture. The frozen roast potato is still the company’s most recognizable product, and it has long promoted the idea of homemade results without homemade effort. They are truly accessible and can be found in stores like Tesco, Sainsbury’s, Morrisons, ASDA, Waitrose, and Ocado. Though it’s important to note that Aunt Bessie’s themselves describe the product as “if anyone asks, you made them from scratch.” Whether this makes them a shortcut or just a useful ingredient depends mostly on attitude.
The no-refreeze rule is the one thing to remember. It is not recommended to put the potatoes back in the freezer after they have been cooked or defrosted. The air fryer method takes care of everything else; just cook what you need and maintain sensible portions. The performance of different batches at different times of the year is another variable. Aunt Bessie’s recognizes that potato quality varies seasonally, so it may take a little longer to achieve the perfect golden color. Toward the end of cooking, a little visual attention is always worthwhile.
Cooking Aunt Bessie’s roast potatoes in the air fryer is definitely worth trying, whether you’re trying a full Sunday roast or just want something proper to go with a weeknight chicken. Given the minimal effort required, the results are dependable in a way that seems almost unfair. In roughly twenty minutes, the edges are crispy, and the centers are soft. That’s precisely what’s required on certain Sundays.
