What Is This Korean Dish?
These easy Korean-style cucumber pickles are a colorful, refreshing side dish inspired by the sweet-and-tangy pickles often enjoyed alongside Korean meals. Crisp cucumbers are combined with onion, red and yellow bell peppers, and Cheongyang chili peppers, then covered with a hot vinegar brine seasoned with sugar, salt, and pickling spices.
Unlike long-fermented Korean pickles, this recipe is designed to be quick and convenient. The vegetables remain crisp while absorbing a bright balance of sweetness, acidity, saltiness, and gentle heat. The colorful vegetables also make the finished pickles especially attractive on the table.
Serve them cold as a refreshing side dish with rice, grilled or fried foods, noodles, or rich Korean dishes. Their tangy flavor is particularly useful for balancing heavier meals.
Why You'll Love This Recipe?
This recipe combines crunchy vegetables with a sweet, tangy, lightly spicy brine and requires only simple preparation.
The cucumbers and bell peppers retain a satisfying bite, while the onion and chili peppers add extra aroma and flavor. Because the vegetables are packed into the jar before the boiling brine is added, preparation is straightforward.
It is also a convenient make-ahead side dish. After chilling in the refrigerator, the flavor improves as the vegetables absorb the brine more evenly.
Ingredients
Main
- 4 Korean cucumbers (or pickling cucumbers)
- 1 onion
- 1 yellow bell pepper
- 1 red bell pepper
- 2 Cheongyang chili peppers (or substitute with jalapeños or serranos)
Pickling Brine
- 4 cups (800 ml) water
- 2 cups (400 ml) white vinegar (approximately 5% acidity)
- 2 cups (320 g) sugar
- 2 tablespoons (30 g) salt
- 2 tablespoons (20 g) pickling spice
- 2 bay leaves (optional)
How to Make It
Step 1 – Sterilizing the Jar
Place a heat-resistant glass jar upside down in a pot of cold water.
Bring the water to a boil and sterilize the jar. Carefully remove it and allow it to air-dry completely before adding the vegetables.
Step 2 – Preparing & Cutting the Vegetables
Wash the cucumbers by rubbing the skin with coarse salt.
Slice the cucumbers into round pieces about 0.7–1 cm thick. Using a crinkle cutter will give them an attractive ridged appearance, but a regular knife works as well.
Cut the bell peppers and onion into bite-sized pieces, approximately 2.5–3 cm cubes.
Slice the Cheongyang chili peppers approximately 0.5 cm thick.
Step 3 – Packing the Jar
Make sure the prepared jar is dry.
Tightly pack the cucumbers, onion, red and yellow bell peppers, and chili peppers into the jar, distributing the vegetables so you get a balanced mixture throughout.
Step 4 – Boiling the Brine
Add 800 ml water, 400 ml white vinegar, 320 g sugar, 30 g salt, 20 g pickling spice, and 2 optional bay leaves to a pot over high heat.
Stir until the sugar and salt have completely dissolved.
Allow the brine to boil vigorously for about 1–2 minutes to release the flavors, then turn off the heat.
Step 5 – Pouring & Aging (Crucial!)
Pour the boiling hot brine directly over the packed vegetables.
If you prefer not to have whole pickling spices in the finished jar, pour the brine through a fine-mesh strainer.
Let the jar cool slightly at room temperature until the hot steam subsides. Close the lid and transfer it to the refrigerator.
Do not leave it at room temperature for too long.
The pickles can be eaten after approximately 24 hours in the refrigerator, but after 1–2 days, the vegetables will absorb the brine more evenly and develop a fuller flavor.

Storage
Keep the cucumber pickles refrigerated at all times after preparation.
They are usually at their best after 1–2 days, when the cucumbers and other vegetables have had enough time to absorb the sweet-and-tangy brine while still maintaining their crisp texture.
For the best quality, enjoy the pickles within approximately 2–3 weeks. Always use clean utensils when removing vegetables from the jar. Avoid introducing food crumbs or other contaminants into the brine, as this can reduce storage quality.
Keep the vegetables submerged in the brine as much as possible. As the pickles sit, their texture will gradually soften, so earlier consumption is recommended if you prefer very crunchy cucumbers.
If you notice an unusual odor, unexpected mold growth, excessive bubbling, or other clear signs of spoilage, discard the pickles rather than tasting them.
Ingredient Substitutions for International Readers
Korean Cucumbers
If Korean cucumbers are difficult to find, pickling cucumbers or Persian cucumbers are good alternatives.
Choose small, firm cucumbers with crisp flesh whenever possible. Very large cucumbers can contain more water and larger seeds, which may produce a softer finished pickle.
Cheongyang Chili Peppers
Cheongyang chili peppers provide a distinct Korean chili flavor and moderate heat.
Outside Korea, jalapeño or serrano peppers are practical substitutes. Adjust the amount according to the heat level of the peppers available to you and your personal preference.
Pickling Spice
Commercial pickling spice is convenient, but if it is unavailable, you can use a simple mixture containing peppercorns and mustard seeds.
Different commercial pickling-spice blends contain different herbs and spices, so the aroma of the finished brine can vary slightly.
White Vinegar
Use regular distilled white vinegar with approximately 5% acidity.
Because vinegar provides the main acidity in this recipe, avoid replacing it casually with a much weaker vinegar. Different vinegars can also noticeably change the flavor and color of the finished pickles.
Bay Leaves
Bay leaves are optional. If you don't have them, simply leave them out rather than replacing them with an unrelated herb.
Shopping Tips
For the best texture, choose small, firm cucumbers without soft spots or wrinkled skin. Fresh cucumbers should feel heavy and crisp.
Choose red and yellow bell peppers that are firm, glossy, and crisp. Fresh peppers contribute both texture and bright color to the finished jar.
Onions should also be firm and free from soft areas.
When buying chili peppers, choose fresh, firm peppers. If Cheongyang chilies are unavailable, fresh jalapeños or serranos are suitable alternatives.
For the vinegar, check the label and choose white vinegar with about 5% acidity. This also provides the clean, sharp flavor intended for this recipe.
Frequently Asked Questions (FAQ)
Can I use regular cucumbers?
Yes, but Korean cucumbers, pickling cucumbers, or Persian cucumbers are preferable because their firm texture works particularly well for this recipe.
If using a larger cucumber, choose the firmest one available. Cucumbers with very large, watery seed centers may become softer after pickling.
When can I start eating the pickles?
You can begin eating them after approximately 24 hours of refrigeration.
However, waiting 1–2 days allows the brine to penetrate the vegetables more evenly, producing a more balanced flavor.
How long do these cucumber pickles keep?
For best quality, keep them refrigerated and enjoy them within approximately 2–3 weeks.
Their texture will gradually become softer the longer they remain in the brine.
Can I make the pickles less sweet?
You can adjust sweetness to personal preference in a future batch, but changing the original proportions will change the flavor balance of this recipe.
For your first batch, following the original recipe is recommended so you can taste the intended balance of sweet, sour, salty, and spicy flavors.
Can I make them spicier?
Yes. The Cheongyang chili peppers already provide some heat. If you enjoy spicy food, you can use hotter fresh chilies or increase the chili flavor according to your preference.
Keep in mind that the heat can become more noticeable as the peppers sit in the brine.
Do I have to use pickling spice?
No. If you prefer a cleaner and simpler brine, you can omit it.
You can also strain the brine through a fine-mesh strainer when pouring it into the jar if you want the spice aroma without leaving the whole spices among the vegetables.
Why do I need to sterilize and completely dry the jar?
Starting with a clean, heat-resistant jar helps keep the finished pickles in better condition during refrigerated storage.
Allowing the jar to dry also prevents unnecessary water from diluting the prepared brine.
Why is the hot brine poured directly over the vegetables?
The boiling brine quickly surrounds the packed vegetables and begins the pickling process while dissolving and distributing the sugar, salt, vinegar, and spices evenly.
Follow the recipe's cooling instructions and refrigerate the jar once the heavy steam has subsided.
Can I add other vegetables?
For the original recipe, I recommend first making it with the listed cucumbers, onion, bell peppers, and chili peppers.
Once you know the original flavor and texture, you can experiment with other firm vegetables in a separate batch. Keep in mind that different vegetables release different amounts of water and absorb brine at different rates.
What should I serve with these pickles?
These pickles work especially well alongside rice dishes, grilled meats, fried foods, noodles, and rich or spicy Korean dishes.
Their cold, crisp texture and vinegar-based flavor help refresh the palate between bites.
