Duck eggs are a prized ingredient in cooking, especially for rich emulsified sauces and homemade mayonnaise. Their larger size, thicker shell, and denser, fattier yolk make them more flavorful than chicken eggs but also require a bit more care when pasteurizing. The goal is the same as with any egg – gently bring the interior temperature up high enough to eliminate harmful bacteria without beginning to cook the egg. With the right thermometer and a little patience, the process is straightforward and well worth the effort for the exceptional results duck eggs deliver.

What you need

• Fresh duck eggs, at room temperature
• A small to medium saucepan deep enough to fully submerge the eggs
• A reliable digital instant-read or candy thermometer
• A spoon or small ladle for lowering eggs into water
• A bowl of ice water large enough to hold the eggs

Directions

1. Remove the duck eggs from the refrigerator and allow them to sit at room temperature for at least 20 to 30 minutes before starting. Duck eggs are dense and need more time than chicken eggs to fully equalize in temperature.
2. Fill your saucepan with enough water to completely submerge the eggs by at least one inch and place it over medium-low heat.
3. Heat the water slowly, monitoring with your thermometer, until it reaches exactly 140°F (60°C). Take your time reaching this temperature – slow and steady gives you better control.
4. Gently lower the duck eggs into the water using a spoon. The water temperature will drop slightly when the eggs are added, so adjust your heat up just slightly to bring it back to 140°F as quickly as possible without overshooting.
5. Hold the water temperature steadily between 140°F and 144°F for 5 to 6 minutes. Stay at your thermometer throughout this entire time and make small heat adjustments as needed. Do not allow the temperature to reach or exceed 145°F or the egg whites will begin to set.
6. Remove the eggs promptly at the end of the hold time and transfer them immediately to the bowl of ice water.
7. Let the eggs cool in the ice water for 8 to 10 minutes to fully stop any residual carryover heat inside the dense yolk.
8. Remove, dry thoroughly, and use immediately or refrigerate.

Tips and notes

• A digital instant-read thermometer is not optional here — the margin between pasteurizing and cooking is narrow and guessing will not work
• Do not skip the room temperature rest before starting, cold duck eggs dropped into warm water create uneven heat distribution and unreliable results
• The eggs will look completely raw and unchanged after pasteurizing, the white will still be fully liquid and clear
• If pasteurizing more than two duck eggs at a time, use a wider pan and increase your hold time by an additional minute to account for the added mass cooling the water
• Pasteurized duck eggs should be used within one week and kept refrigerated
• If you are separating the yolk for mayonnaise, pasteurize the whole egg first and then separate — do not try to pasteurize a separated yolk
• Duck eggs from a local farm or farmers market are ideal since freshness significantly impacts both flavor and emulsification performance

Reasons to pasteurize

• Duck eggs, like chicken 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
• The risk is higher with duck eggs than chicken eggs because ducks are waterfowl and tend to have more exposure to environmental bacteria and contaminated water sources
• 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
• Duck 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 duck 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.
