This might be the simplest condiment I’ve ever taught—and somehow the one people obsess over most.
These pickled red onions convert even the “I don’t like raw onions” crowd. Thinly sliced, gently salted to soften their bite, then quickly pickled with vinegar, water, and a pinch of salt (plus sumac, if you want something special).
Tangy, slightly floral, and quietly transformative, they’re the kind of small, chef-tested upgrade that makes everyday food feel more alive. Once you keep a jar in the fridge, you’ll start adding them to everything—and wondering how you ever cooked without them.
This recipe has 6-8 servings
Ingredients
1 large red onion, very thinly sliced
1 teaspoon fine salt (for salting the onions)
For the quick pickle
1 part vinegar (apple cider or red wine vinegar both work well)
2 parts water
A pinch of salt
1 teaspoon sumac (optional, but highly recommended)
Method
Place the thinly sliced red onion in a bowl. Sprinkle with the salt and gently massage for 30–60 seconds until the onions soften and release some liquid.
Let the onions sit for 10 minutes, then lightly squeeze out the excess liquid and discard it.
In a small bowl or jar, mix the vinegar, water, a pinch of salt, and the sumac (if using).
Add the softened onions to the pickling liquid and toss to coat.
Let sit for at least 15–20 minutes before using. For deeper flavor, refrigerate for 1–2 hours.
Storage:
Keep in a sealed jar in the fridge for up to 1-2 months (but it won’t last that long :)
This is one of those recipes that quietly changes how your food tastes—without asking for extra time, effort, or fancy ingredients. Keep a jar in your fridge and let it do the work for you.
If everyday meals have been feeling a little flat, this is your sign to start here.
