Soft boiled eggs are one of the most timing-sensitive things you can make in a kitchen — 30 seconds too long and a runny yolk becomes jammy; another 60 seconds and it's fully set. The air fryer solves this by making the process completely repeatable: the same temperature, the same time, the same result every single morning without standing over a pot of water watching a clock.
| Doneness Level | Temperature (°F) | Cooking Time | Yolk Description |
|---|---|---|---|
| Very soft / dippy (just-set white) | 250°F | 11–12 min | White just set, very runny yolk |
| Soft boiled (classic runny) | 250°F | 12–13 min | Firm white, fully liquid golden yolk |
| Jammy / custardy yolk | 250°F | 13–14 min | Firm white, thick glossy jammy yolk |
| Medium — slightly set yolk | 250°F | 14–15 min | Firm white, yolk set but still creamy |
| Medium eggs | 250°F | 11–13 min | Reduce by 1 min vs large egg times |
| Large eggs (standard) | 250°F | 12–14 min | Reference size for all times above |
| Cold eggs (from fridge) | 250°F | +1 min | Cold start slows yolk cooking slightly |
The difference between runny and jammy is just 60–90 seconds at 250°F. Cook a test batch the first time you use this method — note the exact time that produces your preferred yolk, then repeat it exactly every time. The air fryer's consistency is its greatest advantage for eggs.
For ramen topping: Cook eggs to 13–14 minutes (jammy yolk). After the ice bath, marinate peeled eggs in a mixture of 3 tbsp soy sauce, 1 tbsp mirin, and 2 tbsp water for 2–4 hours in the fridge. The marinade seeps into the white through any micro-cracks, giving you the glossy, golden-brown marinated eggs found in Japanese ramen bowls.
For toast: Cook to 12–13 minutes (runny yolk). Halve lengthwise, place on thick buttered toast, and finish with flaky salt, cracked black pepper, and a pinch of chili flakes or za'atar. Serve immediately — a runny yolk waits for no one.

For a classic runny-yolk soft boiled egg, cook large eggs at 250°F for 12–13 minutes without preheating, then immediately transfer to an ice bath for 2–3 minutes. For a jammy custard-like yolk — the style popular in ramen — cook for 13–14 minutes. The first time you make them, test at 12 minutes and adjust by 30-second increments from there.
A preheated air fryer creates an immediate blast of heat that cooks the white much faster than the yolk can warm through. This leads to a rubbery, overcooked white with an undercooked yolk — the exact opposite of what you want. Starting in a cold basket allows the heat to build gradually, just like starting eggs in cold water on the stovetop.
For soft boiled eggs, 2–3 minutes in the ice bath is enough — just sufficient to stop carryover cooking without chilling the yolk completely cold. For hard boiled eggs, 5+ minutes is better. Don't leave soft boiled eggs in ice water for 10+ minutes as it cools the yolk to the point where it loses its runny texture entirely.
Soft boiled (12–13 minutes at 250°F) has a fully set white and a liquid, flowing yolk — the kind that runs when you cut it open. Jammy or custardy (13–14 minutes) has a fully set white and a yolk that's thick and glossy rather than liquid — it holds a shape when cut but is soft and rich rather than fully set. Jammy eggs are the style used as ramen toppings; soft boiled is the dippy egg for soldiers.
Yes — cook to your preferred doneness, transfer to the ice bath, then peel and refrigerate in an airtight container for up to 2 days. Unpeeled air fryer eggs can be refrigerated for up to 5 days. To reheat, place peeled eggs in a bowl of warm (not hot) water for 2–3 minutes — enough to take the chill off without cooking further.
Cooking times vary by air fryer model and egg size. Always start in a cold air fryer. Test at 12 minutes first and calibrate to your preferred yolk consistency from there. The ice bath is essential for stopping cooking at the right moment.
