In recipes like Japanese mayonnaise (recipe coming up next), sukiyaki, carbonara, Caesar salad dressings, and ice cream which call for raw eggs or undercooked eggs, you may want to be safe and use pasteurized eggs. You can purchase eggs already pasteurized, but they are rather expensive and often hard to find at your local grocery stores.
However, if you already have an immersion circulator (sous vide machine), it’s actually simple to pasteurize eggs yourself at home.

Why Do We Pasteurize Eggs?
Roughly 1 egg out of every 20,000 eggs will contain the salmonella bacteria which cause food poisoning. Cooking the eggs kills the bacteria, but what about those recipes that require raw or undercooked eggs?
That’s where pasteurized eggs come in. They are gently heated in their shells, just enough heat to kill the bacteria without actually cooking the egg. They are similar to ‘raw egg’ but the only difference is that egg whites of pasteurized eggs are opaque, slightly cloudy, and thickened.
Using pasteurized eggs can reduce or eliminate the risk of being infected by the salmonella bacteria when preparing recipes that call for raw or uncooked eggs.
If you’re serving eggs to young children, pregnant women, or elderly people who may have weaker immune systems, pasteurized eggs are the safest choice.

How to Pasteurize Eggs

Equipment
- a large pot
Materials
- 6 large eggs (50 g each w/o shell) (see Notes below)
- water
Instructions
- Set up an immersion circulator in a large pot of water. Preheat to 135ºF (57ºC).

- Add 6 large eggs (50 g each w/o shell) directly to the water—no need to vacuum seal. Make sure they're fully submerged. Let sit for 75–80 minutes, keeping the water temperature steady.Nami's Tip: To help prevent cracking from thermal shock, let the eggs sit in a bowl of warm water for a few minutes before adding them to the pot (I usually skip this without issues).

- Transfer the eggs to a bowl of ice water for 30 minutes to stop the pasteurization process. Remove and pat dry before using.

To Serve
- Serve beaten pasteurized eggs as a dip for Sukiyaki.

- Use them in Tamago Kake Gohan (TKG) and Mazesoba (Mazemen).

- Pasteurized egg yolks are a key ingredient in Kewpie Mayo—see How to Make Japanese Mayonnaise at home.

To Store
- Keep pasteurized eggs in their shells in an airtight container and refrigerate for up to a week. I don't recommend freezing.
Notes
- This method is based on a Journal of Applied Microbiology study showing 135ºF (57ºC) for 75 minutes reliably kills Salmonella in shell eggs.
- Home pasteurizing doesn’t guarantee 100% safety, but it significantly cuts the risk compared to raw eggs.
- 6 eggs is just my batch size, not a safety limit. Scale up freely as long as your pot keeps them fully submerged with room for water to circulate.
