Green plantains are one of those underrated ingredients that shine when you keep things simple, and frying them in coconut oil with just a hit of flaky sea salt is proof of that. Green plantains are naturally high in resistant starch, which passes through the digestive system largely undigested and acts as a prebiotic ā making them a genuinely smart choice for anyone focused on gut health. Unlike most store-bought chips, which can hide a long list of seed oils, additives, and flavor enhancers, this recipe uses exactly three ingredients, so you know precisely what you're eating. The coconut oil brings a subtle richness without overwhelming the mild, starchy flavor of the plantain, and frying in batches at a consistent 350°F is what gives each chip that satisfying, light crunch. Slicing the rounds as thin and uniform as possible ā ideally with a mandoline ā is the real secret to getting them evenly golden rather than soft in the middle. A sprinkle of flaky sea salt straight out of the oil is all the seasoning they need, and letting them rest on a wire rack means they crisp up beautifully as they cool. These disappear fast, so consider making a double batch.

Score the skin of each plantain lengthwise with a knife, then peel and discard the skin. Using a mandoline set to 1/16-inch (about 1.5 mm) or a sharp knife, slice the plantains crosswise into rounds as uniformly thin as possible ā consistent thickness ensures even frying.
Add the coconut oil to a large heavy-bottomed pot or deep skillet and heat over medium-high heat until it reaches 350°F (175°C) on a deep-fry thermometer.
