Step 1

Put the steamer basket in the pressure cooker pot. Add the water, potatoes, and eggs. Lock lid in place, select High Pressure, 4 minutes cook time, and press start.

Step 2

When the cook time ends, turn off pressure cooker and do a quick pressure release. When the pressure valve drops, carefully remove the lid.

Step 3

Remove the steamer basket from the pressure cooking pot. Put the eggs into ice-cold water to cool. Allow the potatoes to cool separately.

Step 4

In a large bowl, combine the onion, mayo, parsley, pickle juice, and mustard. Add the cooled potatoes and gently mix the mayonnaise mixture into the potatoes.

Step 5

Peel and dice three of the cooled eggs and stir into potato salad. (If needed, add more mayonnaise to achieve desired consistency.) Add salt and pepper to taste.

Step 6

Chill at least one hour before serving. Just prior to serving, top with slices of remaining hard-boiled egg.
