Reheating egg rolls in an air fryer is a simple and effective way to regain their delightful crispiness without compromising on flavour. Start by preheating your air fryer to around 180°C (350°F). While it’s warming up, take your leftover egg rolls out of the fridge and, if desired, lightly spray them with a bit of cooking oil to enhance the crunchiness. Once preheated, place the egg rolls in a single layer in the air fryer basket, making sure not to overcrowd them to ensure even heating. Heat for about 5 to 7 minutes, turning them halfway through to achieve a golden, crispy finish. Keep an eye on them, as cooking times may vary depending on your air fryer model. Once they’re heated through and crispy to your liking, remove them with caution, as they will be hot. Serve immediately and enjoy the delightful texture as if they were freshly made!
