Roni's creamy cucumbers are the chilled side that earns a spot at every cookout: paper-thin cucumber rounds and onion folded into a garlicky olive oil mayo dressing with cider vinegar and parsley. Crunchy, cool, and ready in ten minutes. It is the salad people ask you to bring again.
Pro Tips
- Slice the cucumbers and onion as thinly as you can. A mandoline makes quick work of it, and the texture depends on it.
- Mix the dressing lightly with a fork rather than whisking hard. You want it combined but not loosened.
- A brief chill before serving lets the garlic and vinegar mellow into the cream.
- The French onion variation, with sauteed cooled onion and dried thyme, is a lovely winter twist on the same method.
- For a Middle Eastern version, swap in lemon juice, mint, za'atar, a pinch of cumin, and Aleppo pepper.
Frequently Asked Questions
How far ahead can I make creamy cucumbers?
A few hours is fine, and the flavors improve. Much longer and the cucumbers weep into the dressing, so fold it together the same day.
Can I use dried parsley instead of fresh?
Fresh matters here, since a third of a cup of leaves is part of the salad's freshness. If you must substitute, use 1 tablespoon dried and add it early.
What is Olive Oil Mayo?
It is an egg-free, oil-based paleo mayo that serves as the creamy base here. Any homemade or store-bought paleo mayo works in the same quantity.
What should I serve with this salad?
It is a natural beside anything grilled, like country captain chicken or salmon, and it cools down spicier dishes beautifully.
