For the air fryer method, you’ll want to keep the temperature relatively low. Preheat the air fryer to around 270 or 275 degrees Fahrenheit, which should lessen the risk of unevenly cooking or burning the eggs. Then, just let them cook for 15 minutes to transform them into a perfectly hard-boiled treat. You can adjust the cooking time if you prefer them to be less done than that. You’ll need about 12 minutes for medium-boiled eggs, while soft-boiled eggs are done in 10 minutes.
The difference between the three types of eggs has to do with the firmness of the yolks. Hard-boiled eggs have a completely firm yolk, which is ideal for preparing deviled eggs or whipping up some egg salad with a bit of Greek yogurt. Medium-boiled eggs have a slightly gooey yolk, which makes for a tasty egg salad or is great on top of toast. And soft-boiled eggs have a much gooier center; they’re the perfect addition to avocado toast. Remember that undercooked eggs carry a greater risk of foodborne illness, but it’s still a relatively rare concern at about one in 20,000 eggs.
