Using gentle heat to kill harmful bacteria like Salmonella without actually cooking the egg.

Pasteurizing chicken eggs at home is a simple process that uses gentle heat to kill harmful bacteria like Salmonella without actually cooking the egg. This is especially useful when making homemade mayonnaise, Caesar dressing, hollandaise, or any recipe calling for raw eggs. The key is maintaining a precise water temperature just hot enough to pasteurize but not so hot that the egg begins to cook. This method works best for large eggs – extra large or jumbo eggs may need an additional 30 to 60 seconds.

What you need

• Fresh chicken eggs, at room temperature
• A small saucepan
• An instant-read or candy thermometer
• A bowl of ice water

Directions

1. Remove your eggs from the refrigerator and let them sit at room temperature for at least 15 minutes before starting.
2. Fill a small saucepan with enough water to fully submerge the eggs and heat it over medium-low heat.
3. Using a thermometer, bring the water temperature to exactly 140°F (60°C). This is the critical target — do not let it exceed 145°F or the egg will begin to cook.
4. Gently lower the eggs into the water using a spoon and maintain the temperature steadily at 140°F for 3 minutes for a whole egg. Use your thermometer continuously to monitor and adjust the heat as needed.
5. Remove the eggs immediately and transfer them to the bowl of ice water for 5 minutes to stop any carryover heat.
6. Dry the eggs and use them right away or refrigerate and use within one week.

Tips and notes

• A digital instant-read thermometer is strongly recommended for accuracy because guessing the temperature is not reliable enough for food safety
• Room temperature eggs are important because cold eggs dropped into warm water can cause the temperature to drop too quickly and unevenly
• The egg will look completely raw and unchanged after pasteurizing, which is exactly what you want
• If you plan to use only the yolk, pasteurize the whole egg first and then separate it
• Store-bought pasteurized eggs are available at most grocery stores if you prefer to skip this process entirely

Reasons to pasteurize

• Chicken eggs, like duck eggs, can carry Salmonella bacteria on the shell or occasionally inside the egg, and consuming them raw without pasteurizing carries a real food safety risk
• Pasteurizing is especially important if you are serving food to anyone who is immunocompromised, elderly, pregnant, or very young.
• It gives you confidence when making raw egg recipes like homemade mayonnaise, Caesar dressing, hollandaise, or mousse without worrying about food safety
• Eggs from small farms or backyard flocks have not gone through commercial washing and inspection processes, making pasteurizing a smart precaution

Reasons you might skip it

• If you are using commercially sold pasteurized eggs, the work is already done for you
• The process requires close attention and a reliable thermometer – if you do not have one or are short on time, it adds friction to an otherwise simple recipe
• Some cooks accept the low statistical risk and use fresh, clean, high quality eggs from a trusted local source without pasteurizing
• Pasteurizing adds time and an extra step, which may not feel worth it when making a small batch just for yourself as a healthy adult
• There is a small margin for error – if your temperature creeps above 145°F even briefly, you risk partially cooking the white and the egg becomes unusable for raw preparations

The bottom line

If you are making homemade mayonnaise or any raw egg preparation for yourself alone and your eggs come from a clean, trusted source, the risk is low. If you are sharing it with others, especially anyone vulnerable, pasteurizing is the right call and takes less than 15 minutes total.
