Of everything you can cook sous vide, eggs are where the technique really shows off. A couple of degrees of water temperature is the entire difference between a jammy, spoonable yolk and a fully set, peelable one — and that's exactly the kind of precision a stovetop can't reliably deliver two days in a row. Once you know the temperature you're after, sous vide eggs come out identical every single time.
Why Eggs Are the Best Way to Test a Sous Vide's Accuracy
Egg proteins set at very specific, narrow temperatures — the white firms up around 145°F–149°F, while the yolk doesn't fully set until closer to 158°F. That narrow band is why a circulator with tight temperature accuracy matters so much here: a machine that drifts even a couple of degrees can turn a "jammy" egg into a fully hard one. The EMBENLY Sous Vide's ±0.3°C accuracy across its 50°F–194°F (10°C–90°C) range is well suited to this kind of precision cooking, since every egg style below sits comfortably within that window.
Sous Vide Egg Temperature Chart
| Style | Temperature | Time | What You Get |
|---|---|---|---|
| Warm & barely set | 140°F (60°C) | 45–60 min | Very soft, custardy white; liquid yolk |
| Onsen-style | 145°F (63°C) | 45–60 min | Jammy, spoonable white and yolk — the classic Japanese hot-spring egg |
| Soft-poached replacement | 149°F (65°C) | 45–60 min | Firmer white, still-runny yolk — good on toast or ramen |
| Jammy & peelable | 167°F (75°C) | 13 min | Fully set white, jammy yolk — cooked in the shell, easy to peel |
| Fully hard-cooked | 176°F (80°C) | 15 min | Firm white and yolk, peels cleanly like a traditional hard-boiled egg |
| Custard-style egg bites (out of shell) | 172°F (78°C) | 60 min | Smooth, silky texture — blend eggs with milk or cream and cheese, pour into small jars before cooking |
How to Cook Sous Vide Eggs
In the shell (onsen, soft, jammy, or hard):
- Fill your water bath and set it to your target temperature from the chart above.
- Once the water is at temperature, gently lower whole eggs (straight from the fridge) into the water using a spoon.
- Cook for the listed time.
- Transfer to an ice bath for a couple of minutes before cracking or peeling — this stops the cooking and makes peeling easier for the higher-temperature styles.
Out of the shell (egg bites):
- Whisk eggs with milk or cream, salt, and any mix-ins like shredded cheese or chopped vegetables.
- Pour into small, sealable jars, leaving a little headspace, and seal the lids.
- Submerge the jars in the water bath at 172°F (78°C) for about an hour.
- Cool slightly before unmolding.
Tips for Consistent Results
- Use eggs straight from the fridge and be consistent about it — starting temperature affects timing slightly, and keeping it the same each time makes your results repeatable.
- Don't skip the ice bath for the higher-temperature styles; it makes a real difference in how cleanly the shell comes off.
- Batch cook a dozen at once. Since the water bath holds temperature evenly no matter how many eggs are in it, cooking one egg or twelve takes the same amount of time.
- Label your jars if you're making a batch of egg bites in different flavors, since they all look similar once sealed.
Frequently Asked Questions
What's the difference between an onsen egg and a soft-poached egg made sous vide? It comes down to a few degrees. Onsen-style, at 145°F, gives you a jammy white and yolk that are both soft enough to eat with a spoon. A slightly higher temperature, around 149°F, firms the white up more while the yolk stays runny — closer to what you'd expect from a traditional poached egg.
Why does the jammy, peelable egg cook for such a short time compared to the others? At 167°F, the egg is cooking closer to the temperature it needs to fully set, so it needs far less time than the lower, slower styles — 13 minutes is enough to set the white and leave the yolk jammy, without needing the 45–60 minute window that lower temperatures require.
Can I cook a dozen eggs at once without changing the timing? Yes. Because the water bath maintains an even temperature regardless of how much is submerged, cooking one egg or a full dozen takes the same amount of time — this is one of the more convenient parts of doing eggs sous vide.
Do I need special containers for egg bites? Small, sealable glass jars (like small mason jars) work well, since they need to be fully sealed before going into the water bath.
Is precision really necessary for eggs, or is a couple of degrees not a big deal? For eggs specifically, a couple of degrees matters more than almost anything else you'd cook sous vide — it's the difference between a runny yolk and a fully set one. That's part of why an accurate circulator like the EMBENLY Sous Vide (±0.3°C) makes a visible difference with eggs in particular.
