How to Pasteurize Eggs at Home: Easy Methods for Safe Baking

Healthy Tips and Tricks

Whether you’re making tiramisu, mousse, mayonnaise, or a no-bake dessert like coffee brick cake, pasteurizing eggs at home is a smart and safe choice. Here are all the best methods you can use in your own kitchen, with or without special equipment.

1. Hot Sugar Syrup Method (Yolks or Whites with Sugar)

✅ Perfect for zabaglione, semifreddo, tiramisu or Italian buttercream

You’ll need:

Saucepan and food thermometer

Steps:

Prepare a sugar syrup by boiling water and sugar to 121 °C (250 °F).
While beating the yolks, slowly drizzle the hot syrup into the bowl.
The heat from the syrup pasteurizes the eggs as they whip.

For whites:
Same process, but heat to 60 °C (140 °F).

This is a popular method in professional pastry kitchens.

2. Whole Egg in Shell – Hot Water Method

✅ Ideal for recipes using whole raw eggs

You’ll need:

Saucepan and food thermometer

Steps:

Heat water in a saucepan to 60 °C (140 °F).
Gently place the whole eggs in the water using a spoon.
Maintain the temperature between 60–61 °C (140–142 °F) for 3 to 5 minutes.
Remove the eggs and cool them quickly in cold water.

⚠️ Be precise: If the temperature goes over 61 °C, the eggs may start to cook.

3. Steam Oven Method (Only if you own a steam oven)

Set your steam oven to 60–62 °C (140–143 °F).
Place the whole eggs on a rack and steam them for about 10 minutes.
Cool them immediately in cold water.

✅ This method only works if your oven can control temperature and humidity precisely.

❌ Methods Not Recommended

Microwave: Very hard to control, risk of explosions or uneven cooking.
Boiling water without a thermometer: You could either under-pasteurize or cook the eggs unintentionally.

Always use a thermometer for safety and precision.

Storage Tips

Store pasteurized eggs in the refrigerator and use within 2–3 days.
You can freeze pasteurized egg whites, but not yolks on their own, as they become too thick or gelatinous when frozen.
