Ingredients
Method
- Cut the onions in half, then slice them very thinly. If you have a vegetable slicer or mandoline, it can make this step even easier.

- Place the sliced onions in a bowl. Add sugar, vinegar, soy sauce, salt, and black pepper. Mix well until the onions are evenly coated and start to soften.
- Transfer to a serving bowl. Enjoy as a refreshing side dish—especially perfect with grilled or BBQ meat.

Notes
-
Best served fresh:
You can enjoy it right after mixing, but letting it sit for 10–15 minutes helps the onions absorb more flavor. -
Slice thinly:
The thinner the onion slices, the faster they’ll soften and soak up the sauce. A mandoline slicer works great! -
Type of vinegar:
Apple cider vinegar adds a mild sweetness, while white vinegar gives a sharper tang. Use what you prefer! -
Adjust sweetness or acidity:
If you like it more sour, reduce the sugar or add a little extra vinegar. Prefer it sweeter? Add ½ tsp more sugar. -
Spicy kick:
Add a bit of wasabi, fresh chili, or even a dash of gochugaru (Korean chili flakes) for a spicy version. -
Storage:
This is meant to be a quick pickle, but it can be stored in the fridge for up to 2 days. The onions will soften more over time.
