The Healthy Indulgence
Kerala's banana chips, traditionally fried in coconut oil, are iconic. However, the deep-frying process means they absorb a significant amount of oil. An air fryer offers a fantastic alternative by using rapidly circulating hot air to cook and crisp the chips, reducing
the required oil by a huge margin. While a small amount of oil is recommended for achieving the best colour and texture, air frying can cut calories by 70-80% compared to deep frying. You get the satisfying crunch and authentic banana flavour without the guilt, making it a snack you can enjoy more often. The result is a chip that is crispier and drier, though it won't perfectly replicate the rich, oil-infused taste of the traditional version.
Start with the Right Banana
The secret to authentic, crispy chips lies in the banana itself. You must use raw, green plantains, specifically the Nendran variety if you can find it. This type of banana, also known as a Kerala banana or 'ethakka', is starchy, firm, and low in sugar. These qualities are essential for chips that hold their shape and become crunchy when cooked. Do not use regular yellow eating bananas; their high sugar and moisture content will cause them to caramelise and turn soft or even burn, rather than crisping up. The banana should be completely green and firm to the touch for the best outcome.
Perfect Preparation for a Perfect Chip
Proper prep work is non-negotiable for achieving that coveted crunch. Start by peeling the raw plantains. Many recipes recommend soaking the peeled bananas in a bowl of water mixed with turmeric and salt for 10-30 minutes. This step serves multiple purposes: it prevents the slices from browning, helps remove excess starch, and seasons the banana from the inside. After soaking, it is crucial to pat the bananas completely dry with a kitchen towel. Any remaining moisture will turn to steam in the air fryer, making your chips soggy instead of crispy. The final and most critical step is slicing. Use a mandoline slicer to create uniformly thin slices, about 1-2mm thick. Even thickness ensures the chips cook at the same rate, preventing some from burning while others remain soft.
The Air-Frying Method
Once your slices are prepped and dry, toss them in a bowl with a very small amount of oil—about one or two teaspoons is enough for a large batch. Coconut oil is the traditional choice and adds a hint of authentic flavour. Preheat your air fryer, as starting with a hot basket helps immediately crisp the surface of the chips. Temperatures between 160°C and 180°C (320°F to 350°F) are generally recommended. A lower temperature helps cook the chips through without burning the edges. Arrange the slices in a single layer in the air fryer basket, ensuring they do not overlap. Overcrowding the basket will cause the chips to steam. Cook for 12-18 minutes, shaking the basket every 4-5 minutes to promote even browning. Keep a close eye on them after the 10-minute mark, as thin chips can go from golden to burnt very quickly.
Achieving and Storing the Crunch
Don't be alarmed if the chips feel slightly soft or flexible when you first take them out of the air fryer. They will continue to crisp up as they cool on a wire rack or paper towel. If your chips aren't crispy, the likely culprits are slices that were too thick, bananas that were slightly ripe, or an overcrowded air fryer basket. Once completely cool, you can season them with a sprinkle of salt. For different flavour profiles, try adding a pinch of chilli powder or chaat masala while the chips are still warm. Store your homemade air-fried banana chips in an airtight container at room temperature. Because they contain so little oil, they stay fresh for longer than their deep-fried counterparts and can last for one to two weeks.
