Instructions

1
Start with a nearly empty 30 oz mayonnaise jar, leaving the remaining mayonnaise at the bottom and on the sides.
2
Thinly slice the cucumbers and sweet Vidalia onion. A mandoline is helpful for uniform slices. Finely chop the fresh dill.
3
Pack the sliced cucumbers, onions, and chopped dill into the mayonnaise jar, layering them alternately.
4
Sprinkle the granulated sugar over the vegetables in the jar.
5
Pour white vinegar into the jar until the vegetables are covered and the jar is nearly full.
6
Add a pinch of salt.
7
Seal the jar tightly and shake vigorously to combine all the ingredients and coat the vegetables in the creamy dressing.
8
Refrigerate for at least a few hours before serving to allow the flavors to meld.

Tips & Notes

Pro tips

Slice cucumbers and onions uniformly thin (about 1/8 inch) so they absorb the dressing evenly and look appealing.
Use the last bit of mayo still clinging to the jar walls—it emulsifies better with vinegar when there's less air, creating a creamier dressing.
Add cucumbers and onions no more than 2 hours before serving to preserve crispness; add earlier if you prefer softer, more pickled vegetables.
Taste before serving and adjust salt and sugar to balance the vinegar's tang with sweetness.

Substitutions

Mayonnaise → Greek yogurt or sour cream (use same amount; dressing will be tangier)
White vinegar → Apple cider vinegar (reduces sweetness; use 1 tablespoon less sugar)
Fresh dill → Fresh tarragon or 1 teaspoon dried dill (changes flavor profile slightly)
Vidalia onion → Red onion (sharper taste; use only 3/4 of the onion and add 1/2 tbsp extra sugar)

Storage & make-ahead

Store in an airtight container in the refrigerator for up to 5 days; serve cold or at room temperature.

Common Questions

Can I use regular onions instead of Vidalia?

Yes, but Vidalia onions add natural sweetness that balances the vinegar. If using yellow or white onions, increase the sugar by 1/2 tablespoon to compensate.

How long do these cucumbers keep?

Store in an airtight container in the refrigerator for up to 5 days. The cucumbers will soften slightly over time as the vinegar penetrates.

Can I make this ahead?

Yes, prepare the dressing in the jar and add sliced cucumbers and onions up to 2 hours before serving for the crispest texture, or overnight for a more pickled consistency.
