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)
Modernist Cuisine (Nathan Myhrvold) is the canonical reference for sous-vide egg science.
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.
