Preheat the air fryer: Set your Ninja air fryer to 300°F (150°C) for 3–5 minutes.
Preheating helps keep timing consistent.
Arrange the eggs: Place eggs in a single layer in the basket. Leave a little space between them for even airflow. No water needed.
Choose your time: For soft-set jammy yolks, cook 10–11 minutes.
For classic hard boiled, cook 12–14 minutes. For fully firm yolks, cook 15–16 minutes. Most people love 13 minutes for a classic hard boiled texture.
Prepare an ice bath: While eggs cook, fill a large bowl with cold water and plenty of ice.
Chill immediately: When time is up, transfer eggs straight into the ice bath. Chill 5–10 minutes to stop the cooking and make peeling easier.
Peel and enjoy: Gently roll each egg on the counter to crack, then peel under a thin stream of running water if desired.
The shells should slide off cleanly.
