How long does a sous-vide egg take?
Sous-vide eggs cook 45–75 minutes depending on target texture. Classic 63°C egg: 60–75 min. Soft set: 45 min. Hard cooked: 45 min at 75°C. Eggs are time-flexible at sous-vide.
The full answer
Sous-vide eggs are temperature-precise. The protein in egg whites coagulates at different temperatures than yolk — so the same temperature held for ~1 hour produces consistent results that hard-boiling can never match.
**The "63 egg" (classic sous-vide):** - Temperature: 63°C (145°F) - Time: 60–75 minutes (45 min minimum, 90 min max for flavor) - Result: white just set, yolk a custardy "molten" texture - Most iconic sous-vide preparation
**Other timing targets:** - 60°C (140°F), 60–75 min: barely-set white, runny yolk (egg drop-style) - 63°C (145°F), 60–75 min: classic onsen tamago / 63°C egg (standard) - 65°C (149°F), 60 min: firm white, soft-set yolk - 71°C (160°F), 45–60 min: firm everything (soft-boiled equivalent) - 75°C (167°F), 45 min: firmer hard-cooked
**Time vs. temperature:** At sous-vide temps, eggs are MORE forgiving than hard-boiling. After ~45 min, the egg reaches target temperature. Time past that doesn't dramatically change texture for up to 4 hours. Beyond 4 hours: yolk slowly firms.
**Method:** 1. Heat water bath to target temperature 2. Lower whole eggs (in shell) into bath via slotted spoon 3. Cook for time 4. Use immediately, or shock in ice for storage
**Storage:** Cooked sous-vide eggs hold in ice water 1–2 hours at most before texture changes. For batch cooking, do them right before service.
**Best applications:** - 63°C: topping rice bowls, ramen, salads, eggs benedict - 65°C: deviled eggs (clean peel, slightly creamy yolk) - 71°C: replacement for boiled eggs (easier-to-peel)

Time ranges by condition
| Condition | Duration | Note |
|---|---|---|
| Classic 63°C onsen egg | 60–75 minutes | — |
| Firm white, soft yolk (65°C) | 60 minutes | — |
| Sous-vide hard cooked (75°C) | 45 minutes | — |
| Extended hold time (any temp) | up to 4 hours | Texture forgiving in sous-vide |
What changes the time
- Temperature precision. Sous-vide circulator must hold within ±0.5°F; cheap kettle-with-thermometer drifts 5°F+
- Egg size. Standard large eggs; jumbo eggs add 5–10 min; medium eggs subtract 5 min
- Starting temperature. Cold from fridge adds ~5 min to reach equilibrium; room temp eggs faster
- Batch size. 1–12 eggs at once; doesn't change time as long as circulator maintains temp
Common questions
What does a 63°C egg taste like?
The white is barely set (slightly gelatinous), the yolk is custard-like (thick liquid). Falls into food like a sauce. Iconic in modern Japanese cuisine (onsen tamago) and high-end restaurants.
Can I make sous-vide eggs without a circulator?
Risky — eggs need temperature stable to within 2–3°F. A stovetop with a thermometer + babysitting can work but is tedious. Best to use a $50–100 immersion circulator.
Why don't hard-boiled eggs taste like sous-vide eggs at the same temperature?
Hard-boiled eggs are cooked from outside-in in 212°F water → outer white over-cooks before yolk reaches target. Sous-vide brings the whole egg to a single uniform temperature, producing precise textures impossible with boiling.
