How To Pickle Red Onions Fast

1. Preparation: Thinly slice the onions (using a mandoline is recommended for uniform thin slices). Divide the sliced onions between 2 (16-ounce) jars or 3 (10-ounce) jars. If you’re using garlic and peppercorns, place them in each jar.
2. Making the Brine: In a medium saucepan, heat the vinegar, water, sugar, and salt over medium heat. Stir the mixture until the sugar and salt dissolve, which should take about 1 minute. Allow the brine to cool.
3. Pickling the Onions: Pour the cooled brine over the onions in the jars. Set them aside to cool to room temperature. Once cooled, store the jars in the fridge.
4. Ready to Eat: The pickled onions will be ready to eat once they turn bright pink and become tender. This can take about 1 hour for very thinly sliced onions or overnight for thicker sliced onions. They can be stored in the fridge for up to 2 weeks.

Recipe Tips

• Try adding some peppercorns or garlic to the onions for a different taste.
• Play around with different vinegars. Mixing white wine with rice vinegar or using apple cider with white vinegar can be tasty.
