{"schema":"askedwell-answer-v1","url":"https://askedwell.com/pages/how-long-does/sous-vide-egg","question":"How long does a sous-vide egg take?","short_answer":"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.","long_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.\n\n**The \"63 egg\" (classic sous-vide):**\n- Temperature: 63°C (145°F)\n- Time: 60–75 minutes (45 min minimum, 90 min max for flavor)\n- Result: white just set, yolk a custardy \"molten\" texture\n- Most iconic sous-vide preparation\n\n**Other timing targets:**\n- 60°C (140°F), 60–75 min: barely-set white, runny yolk (egg drop-style)\n- 63°C (145°F), 60–75 min: classic onsen tamago / 63°C egg (standard)\n- 65°C (149°F), 60 min: firm white, soft-set yolk\n- 71°C (160°F), 45–60 min: firm everything (soft-boiled equivalent)\n- 75°C (167°F), 45 min: firmer hard-cooked\n\n**Time vs. temperature:**\nAt 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.\n\n**Method:**\n1. Heat water bath to target temperature\n2. Lower whole eggs (in shell) into bath via slotted spoon\n3. Cook for time\n4. Use immediately, or shock in ice for storage\n\n**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.\n\n**Best applications:**\n- 63°C: topping rice bowls, ramen, salads, eggs benedict\n- 65°C: deviled eggs (clean peel, slightly creamy yolk)\n- 71°C: replacement for boiled eggs (easier-to-peel)\n\nModernist Cuisine (Nathan Myhrvold) is the canonical reference for sous-vide egg science.","duration_iso":"PT1H","ranges":[{"condition":"Classic 63°C onsen egg","duration":"60–75 minutes"},{"condition":"Firm white, soft yolk (65°C)","duration":"60 minutes"},{"condition":"Sous-vide hard cooked (75°C)","duration":"45 minutes"},{"condition":"Extended hold time (any temp)","duration":"up to 4 hours","note":"Texture forgiving in sous-vide"}],"variables":[{"name":"Temperature precision","effect":"Sous-vide circulator must hold within ±0.5°F; cheap kettle-with-thermometer drifts 5°F+"},{"name":"Egg size","effect":"Standard large eggs; jumbo eggs add 5–10 min; medium eggs subtract 5 min"},{"name":"Starting temperature","effect":"Cold from fridge adds ~5 min to reach equilibrium; room temp eggs faster"},{"name":"Batch size","effect":"1–12 eggs at once; doesn't change time as long as circulator maintains temp"}],"sources":[{"label":"Nathan Myhrvold, \"Modernist Cuisine\"","note":"Canonical sous-vide egg temperature/time science"},{"label":"J.

Falls into food like a sauce. Iconic in modern Japanese cuisine (onsen tamago) and high-end restaurants."},{"question":"Can I make sous-vide eggs without a circulator?","answer":"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."},{"question":"Why don't hard-boiled eggs taste like sous-vide eggs at the same temperature?","answer":"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."}],"keywords":["sous vide egg","63 egg","onsen tamago","sous vide cooking","how long to sous vide eggs"],"category":"cooking","date_published":"2026-05-20","date_modified":"2026-05-20","license":"CC-BY-4.0","attribution":"https://askedwell.com"}
