Egg rolls are often deep-fried, but you can also easily make them in the oven or air fryer. Preheat the oven to 390 degrees Fahrenheit (200 °C) (not necessary for the air fryer) and bake the mini spring rolls on a baking sheet in a single layer for 8 minutes. They will be slightly lighter in color (see photo, the bottom mini spring roll is fried, the top mini spring roll is air fried), but just as tasty!
