Ingredients for Pickled Red Onions

You only need a handful of ingredients to make this best pickled red onion recipe at home.

Red onion

Use 1 large red onion, thinly sliced. Red onions are naturally colorful and slightly sharp, which makes them perfect for quick pickling. Once they sit in the brine, they soften and turn a bright pink color.

For the best texture, slice the onion as thin as you can. A sharp knife works fine, but a mandolin can help you get even slices.

White vinegar

White vinegar gives these Pickled Red Onions a clean, sharp, tangy flavor. It is also easy to find and works well for quick pickling.

If you are wondering about the best vinegar for pickled red onions, white vinegar is a great classic choice. Apple cider vinegar also works if you want a softer, slightly fruity taste. You can see the same bright, tangy idea in this easy pickled cauliflower recipe if you want another simple pickled vegetable to try.

Sugar

Sugar balances the sharp vinegar and gives the onions a light sweetness. The goal is not to make them taste sugary. It simply rounds out the flavor.

Salt

Kosher salt works well here. You can also use fine sea salt, but you will need a little less because it is more concentrated by volume.

Cold water

Cold water softens the brine and keeps the vinegar from tasting too harsh. It also helps cool the mixture before the onions go into the fridge.

How to Make Pickled Red Onions

This method is simple and quick. It is not fully no cook because the vinegar, sugar, and salt are briefly warmed to dissolve everything, but it still takes only a few minutes.

Step 1: Slice the onion

Thinly slice 1 large red onion. Add the onion slices to a clean mason jar.

Try to keep the slices thin and even. Thin slices soften faster and absorb the brine better.

Step 2: Make the brine

In a small saucepan, add:

• 1 cup white vinegar
• 2 tablespoons sugar
• 1 tablespoon kosher salt or 2 teaspoons fine sea salt
• Heat over medium heat and whisk until the sugar dissolves.

You do not need to boil it for a long time. Just heat it enough so the sugar and salt melt into the vinegar.

Step 3: Add cold water

Remove the saucepan from the heat and stir in 1 cup cold water.

This helps balance the vinegar and cools the brine slightly before it goes over the onions.

Step 4: Pour over the onions

Pour the brine over the sliced onions in the jar.

Use a fork or spoon to press the onions down so they are fully covered by the liquid.

Step 5: Chill before serving

Seal the jar with a lid and refrigerate for at least 1 hour.

You can taste them after 1 hour, but the flavor gets even better after a few hours. The onions will soften, turn bright pink, and become tangy, crisp, and lightly sweet.
