In Korea there are many versions of tong sam gyup goo yi (literally "whole pork belly"), a favorite ingredient that is often grilled, roasted in the oven or fried on the stovetop. Here it is cooked in an air fryer, which is gaining in popularity there, for an easier, splatter-free alternative to traditional versions; it also makes clean-up a breeze. The pork belly is just as browned and crispy on the outside while the interior stays tender and juicy. This update also gets a spicy kick from a streamlined gochujang sauce made with pantry staples. Brush it on in the last few minutes of cooking to create a gorgeous, caramelized coating. Kabocha squash, air fried with the pork belly, rounds out the meal.
