Pantry: Pickled Red Onions

There’s always a jar of something sharp in a good kitchen.

Not loud. Not complicated. Just sitting there—doing quiet work.

Pickled red onions are that jar.

They cut through richness, wake up leftovers, and make even the most thrown-together meal feel like it had a plan. Tacos, eggs, grain bowls, roast chicken straight from the fridge—suddenly it all lands a little brighter.

This is the version I come back to. Simple, balanced, and just aggressive enough to matter.

Ingredients

• 1 large red onion ( 250–300 g), very thinly sliced

• 120 g red wine vinegar

• 120 g water

• 25 g granulated sugar

• 8 g kosher salt

Optional, but worth it :

• pinch red pepper flakes

• strip of orange peel

• 1 small garlic clove, lightly crushed

Method

1. Slice the onions thin

As thin as you can get them. This is the difference between “good” and “you keep reaching into the jar.”

2. Make the brine

In a small saucepan, combine vinegar, water, sugar, and salt.

Heat just until everything dissolves—don’t boil it into submission.

3. Pour and press

Place onions in a jar or bowl. Pour the warm brine over the top.

Press them down so everything is submerged.

4. Let it sit

They’re ready in about 30 minutes, but better after a few hours.

Best the next day—when they’ve gone fully pink and a little softer around the edges.

5. Store

Keep in the fridge for up to 2 weeks (they won’t last that long).

Notes (the part that actually matters)

• Balance is everything: If they taste too sharp → add a pinch more sugar. Too flat → a splash more vinegar.

• Don’t overheat the brine: You’re dissolving, not cooking.

• Thinner = better texture: Thick slices feel aggressive in the wrong way.
