What Is This Korean Dish?
Korean Onion Pickles, known as Yangpa-Jangajji (양파장아찌), are a simple Korean side dish made by soaking fresh onions and chili peppers in a sweet, tangy soy sauce brine. The onions stay pleasantly crisp while absorbing a balance of savory, sweet, and sour flavors.
In Korea, jangajji-style pickles are commonly served as a banchan, or side dish, alongside rice and many main dishes. The refreshing acidity of the pickled onions is especially enjoyable with rich or savory foods. Green and red chili peppers add freshness, color, and a mild spicy kick. This recipe is easy to prepare at home and requires only a handful of everyday ingredients. After the onions have had time to absorb the brine, they become flavorful while still retaining their satisfying crunch.

Ingredients
This recipe uses only a small number of ingredients. For the best texture, choose firm, fresh onions and fresh chili peppers without soft spots.
- 2 onions (400 g)
- 3 green chili peppers (or regular mild chili peppers)
- 1 red chili pepper
- 200 ml water
- 160 ml soy sauce
- 120 g sugar
- 130 ml vinegar
The onions are the main ingredient, while the green and red chili peppers add both flavor and color. The water, soy sauce, sugar, and vinegar form the pickling brine.
How to Make Korean Onion Pickles
The process is simple, but preparing a clean, dry jar and following the order of the brine ingredients are important. Follow the six steps below in order.
Step 1: Sterilize the Jar
Place a heat-resistant glass jar upside down in a pot of cold water. Bring the water to a boil to sterilize, then dry out any moisture completely.
Starting with a clean jar helps keep the finished pickles fresh during refrigerated storage. Make sure there is no remaining moisture inside the jar before adding the vegetables.
Step 2: Prep the Vegetables
Cut the onions into bite-sized pieces that easily fit on a spoon. Slice the green and red chili peppers into 1 cm rounds.
Keeping the onion pieces at a convenient eating size makes the finished pickles much easier to serve directly from the jar.
Step 3: Pack the Jar
Tightly pack the dried jar with the mixed onions and chili peppers, alternating them evenly without any empty spaces.
Distributing the peppers throughout the onions helps spread their flavor more evenly through the jar.
Step 4: Boil the Pickling Brine
Combine 200 ml water, 160 ml soy sauce, and 120 g sugar in a pot. Simmer over medium heat, stirring until the sugar dissolves.
Be careful, as it can boil over quickly!
Stirring while heating helps the sugar dissolve evenly into the soy sauce mixture.
Step 5: Add Vinegar and Pour
Once the brine boils and the sugar dissolves, turn off the heat and stir in 130 ml vinegar to preserve its fresh aroma.
Adding the vinegar after turning off the heat helps retain its bright, tangy character.
Step 6: Cool and Store
Pour the hot brine over the vegetables. Let it cool slightly, then refrigerate. Consume within a week.
Make sure the vegetables remain well surrounded by the pickling liquid while stored.

Serving Suggestions
Korean Onion Pickles are designed to be eaten in small portions as a side dish rather than as a main dish. Their sweet-and-sour flavor can provide a refreshing contrast when the rest of the meal is rich or strongly seasoned.
Serve a few pieces of onion together with some of the chili slices and a small amount of the brine. Because the onions are cut into bite-sized pieces, they are easy to pick up with chopsticks or eat with a spoon.
They can be served as part of a larger Korean meal with steamed rice and several other banchan, or simply added to an everyday meal when you want something crisp and tangy on the side.
Storage
Store the Korean onion pickles in a clean, airtight container in the refrigerator.
Keep the onions submerged in the pickling brine as much as possible. This helps them absorb the seasoning evenly and maintains the characteristic flavor of the dish.
For this recipe, the pickles are best consumed within 1 week.
Always use clean utensils when removing onions from the container. Avoid repeatedly leaving the jar at room temperature for long periods, and return it to the refrigerator after serving.
Ingredient Substitutions for International Readers
Some Korean chili peppers may be difficult to find outside Korea. These substitutions can make the recipe easier to prepare internationally without changing its basic character too much.
Green chili peppers → Jalapeño or mild chili peppers
If Korean green chili peppers are unavailable, jalapeños can be used when you want more heat. For a milder version, choose a mild green chili pepper instead.
Red chili pepper → Red bell pepper or omit
If you cannot find an appropriate red chili pepper, a little red bell pepper can provide color with much less heat. You can also leave it out.
Soy sauce → Tamari
Tamari can be used when regular soy sauce is unavailable. Because products can differ in saltiness, keep the flavor difference in mind when choosing a substitute.
Sugar → Brown sugar or honey
Brown sugar or honey can be used as alternatives, although either substitution may slightly change the flavor and character of the brine.
Shopping Tips
For the best results, choose firm, heavy onions with dry skins and no obvious soft spots. Fresh onions provide a better crisp texture after pickling.
Choose chili peppers that feel firm and look fresh. Avoid peppers that are wrinkled, damaged, or unusually soft.
For the soy sauce, use a good-quality soy sauce suitable for everyday Korean cooking. Since soy sauce is one of the main components of the pickling liquid, its flavor has a noticeable effect on the finished dish.
Frequently Asked Questions (FAQ)

Yes. Use mild peppers or omit the chili peppers. The onions and soy-vinegar brine will still provide plenty of flavor.

For best quality and food safety, make fresh brine for a new batch.
Why should the jar be completely dry?
A clean, dry container helps maintain better storage conditions for the finished pickles.
Can I use regular mild chili peppers?
Yes. The original recipe already allows regular mild chili peppers as an alternative to the green chili peppers.
How should I serve the pickled onions?
Serve a small portion as a Korean side dish alongside rice and other savory foods. A few onion pieces and chili slices are usually enough to add a refreshing contrast to a meal.
