We all know the sheer convenience of throwing a batch of potatoes into the Air Fryer. It is the ultimate kitchen hack for mimicking our favourite pub grub. But if we are being brutally honest, achieving that elusive, shatteringly crisp exterior while maintaining a fluffy centre is easier said than done.

The Great Oil Myth

For years, home cooks have been led to believe that the secret to the perfect crunch lies in the oil. A generous glug of sunflower or olive oil before hitting the basket seems logical, right? Wrong. Over-oiling your spuds is the exact reason they are coming out soggy, greasy, and limp. The true secret to flawlessly crispy air fryer chips doesn’t come from a bottle at all—it comes from a humble box sitting right at the back of your baking cupboard.

The Secret Ingredient: Cornflour

Yes, you read that right. The missing puzzle piece to your fakeaway Friday is standard cornflour. While usually reserved for thickening gravies or sauces, a light dusting of this powdery pantry staple is the ultimate game-changer for homemade chips.

When you coat your raw, sliced potatoes in a fine layer of cornflour, it immediately absorbs any residual surface moisture. In the intensely hot, circulating environment of the Air Fryer, this starch forms a microscopic crust that crisps up incredibly well, sealing the fluffy potato inside without ever needing a deep-fat fryer.

How to Make the Ultimate Crispy Air Fryer Chips

Ready to massively upgrade your side dish game? Follow this foolproof method for the perfect crunch:

  • Choose the right spud: Opt for floury potatoes like Maris Piper or King Edward for the absolute best texture.
  • Soak and dry: Cut your chips and soak them in cold water for 30 minutes to remove excess potato starch. Drain and pat them completely dry with kitchen roll. Remember, moisture is the ultimate enemy of crispness!
  • The magic dusting: Toss the dry chips in a large bowl with just one tablespoon of cornflour until evenly coated. This is also the perfect time to add your favourite seasonings like smoked paprika, garlic granules, or a hearty pinch of sea salt.
  • Oil lightly: Now, add just one tablespoon of oil or a few sprays of cooking oil, tossing again to combine everything.
  • Air fry to perfection: Cook at 200°C for 20-25 minutes. Crucially, ensure you give the basket a rigorous shake every 8 minutes to guarantee an even, golden crunch across every single chip.

Serve immediately and prepare to be absolutely amazed. Your belief that loads of oil is the only path to a perfectly crispy finish will completely vanish with the very first bite!
