When we serve a Japanese Ichiju Sansai (one soup three dishes) style meal, there’s always one or two kinds of pickled vegetables as part of the set. The pickles are considered as a palette cleanser and are enjoyed between dishes.

In Japan, you can find a great variety of pickles being sold at the grocery stores or the supermarket. Here in the US, I often make my own quick pickles or what we call Asazuke (浅漬け), with vegetables that are readily available such as cucumbers and cabbage. They are easy and versatile, and today let’s make Spicy Japanese Pickled Cucumbers (ピリ辛きゅうりの浅漬け)!

How to Make Spicy Japanese Pickled Cucumbers

Ingredients You’ll Need

  • Japanese or Persian cucumbers – why this variety? Read below.
  • Salt
  • The pickle solution: soy sauce, sesame oil, sugar, and la-yu (Japanese chili oil)
  • Toasted white sesame seeds

What’s La-Yu?

La-yu (辣油, ラー油) is a Japanese chili oil. Japanese don’t really have many spicy dishes, but we use a few dollops of la-yu in some dishes when we want to create some heat.

Chili Oil with Chili Pepper (La-Yu)

You can find La-Yu at Japanese grocery stores, Asian grocery stores, or Amazon.

Overview Steps

  1. Cut cucumbers into chunks and sprinkle salt to withdraw some moisture.
  2. Marinate the cucumbers in the pickling solution for 6 hours or overnight.
  3. Sprinkle sesame seeds and enjoy!

It’s seriously simple yet packed with a lot of punch!

3 Key Tips To Pickle Cucumbers

Tip #1: Use Japanese or Persian cucumbers

Japanese Cucumbers | Easy Japanese Recipes at JustOneCookbook.com

These varieties have less seeds in the center of the cucumber, so when you pickle the cucumbers, they don’t release much moisture and dilute the solution.

Tip #2: Cut the cucumber using “Rangiri” method

Spicy Japanese Pickled Cucumber-step by step-5

Here I slice the vegetable diagonally while rotating the vegetable a quarter (or 45 degrees) between cuts so every cut is random. This Japanese cutting style is called Rangiri (乱切り) and it creates more surface; therefore the cucumbers can absorb more flavors.

3. Salt the cucumbers to withdraw moisture

Don’t worry about sodium here. To pickle the vegetables well, you need the salt to first withdraw some moisture out of the cucumber so it can better absorb the seasonings later.

What to Serve with Spicy Japanese Pickled Cucumbers

It pairs well with many mains and can be served as a snack too, and here are just my recommendations:

Pickles usually contrast in flavor, texture, and temperature to the main dish. They cleanse your palate and give a break between dishes. Hope you enjoy this homemade side dish!
