When I say these are QUICK Pickled Cucumbers and Onions, I am not kidding. Simply whisk together the vinegar/sugar mixture, slice the cucumbers and onions and stir them up. Refrigerate for 1 hour, up to 24 hours. They are perfectly tangy and crunchy. Pile them high on them to this Bulgogi Burger (photo below) or really any Burger, also great as a condiment to Asian food and BBQ.

5 Quick Pickled Cucumber & Onion Recipe

Ingredients

English Cucumber – these are the long cucumbers in the grocery store that usually come wrapped in plastic wrap. They may also be called hot house cucumbers, seedless cucumbers, or burpless cucumbers. They are crisper and denser than a garden cucumber. They also have thinner skin and less (to no) seeds.

Red Onion – a red onion gives the cucumbers a little bite and depth of flavor.

Rice Wine Vinegar – you can find rice wine vinegar with the Asian foods in the grocery store. It is a mild vinegar with a lovely flavor. Buy the natural or unseasoned vinegar- ((but if you bought or have the seasoned, that will work too)).

Ingredients for quick pickled cucumbers and onions

Sugar – a little sugar balances the flavors of the vinegar perfectly.

Canola or Vegetable Oil – just a little oil helps to emulsify the pickle liquid. You only need a little so canola or vegetable oil is the right choice here.

Red Pepper Flakes & Kosher Salt – just a light seasoning is all the pickled cucumbers and onion need.

OXO Mandoline Slicer

Slice Cucumbers & Onions

Slice the cucumbers and onions very thin. I like to use a mandoline on the thinnest setting for the job. But a sharp knife will work great too.

This OXO Mandoline Slicer is under $30 and is great for home kitchen use!

Pickling liquid in a cup

Make Pickle Liquid

Mix all the pickle liquid ingredients together; vinegar, sugar, oil, salt, pepper flakes. Whisk well so the sugar melts into the vinegar.
