Pickled Red Onions v. Red Onions

Historically, pickling vegetables transforms their flavor and  is used to preserve extra produce you have in your kitchen. When you let red onions sit in a brine of vinegar and salt, the taste and texture slightly change, in the most delicious way. Instead of raw, crunchy onions, they become soft and packed with a zingy flavor. Bonus points for the gorgeous pop of pink they add to a variety of recipes that your kids love too. 

Pickled red onions are an easy way to stretch your grocery budget as well. The vinegar and salt mixture kills off any microorganisms that can live on produce, causing food to spoil. In fact, pickling can help your onions last up to two weeks longer! 

Think of it as a prep and preservation hack all in one.

White Vinegar

Vinegar is one of the most important ingredients for pickling because that is how you preserve your sweet red onions. White vinegar is a standard base ingredient because it has over 5% acidity and a neutral flavor to help preserve the sweetness of the onions. Every grocery store carries it near the cooking oils or salad dressings. Plus, it’s very affordable. 

If you have cider, malt, or wine vinegar on hand, you can use those as well. However, they’re likely to alter the flavor of your pickled red onions, so keep that in mind when making any substitutions.

Water

Vinegar has quite a harsh flavor. In order to have the correct amount of acidity to preserve your red onions and avoid overly sour and tart onions, you have to add water. You want a 1:1 ratio of water and vinegar for the best pickling brine. As long as you use water that’s safe to drink, you can use tap water, filtered water, or bottled water.

Cane Sugar

When you heat the brine, the sugar dissolves and balances out the sharp, harsh vinegar taste. You don’t want the liquid to become syrupy like with canned fruit. Add five tablespoons of cane sugar to cut back the acidity from the vinegar. Sugar also absorbs some of the water from the onions so that the water can limit the chances of bacteria growing. 

Sea Salt

It’s best to use salt without any additives when you pickle red onions so that the brine doesn’t become cloudy. We don’t recommend iodized salt, like table salt. Iodized salt has anti-caking agents that don’t dissolve in water and settle on the bottom. The sediments create a murky brine that just doesn’t look appealing. This can also change the taste and texture of your red onions, and we don’t want to lose out on that tangy crunch.  

Canning and kosher salt are also non-iodized salt options that you can use to pickle red onions.

How to Pickle Red Onions

Step 1: Slice your red onions into thin strips with a mandolin or a knife. The mandolin is a quick way to slice uniform strips, but you can still make this recipe with a traditional kitchen knife. 

If using the mandolin, Keep the root end of the onion intact and use a paring knife to cut off the other end. Use your fingers to remove the skin. Use a large knife to cut the onion in half. Hold one onion half with the root side in your dominant hand and the flat, cut side on the mandolin surface. Hold the mandolin with your other hand and gently move the onion back and forth until all of the onion is sliced. Repeat with the other half of the onion.

If using a knife, julienne your onions by cutting the onion in half, removing the skin, and slicing thin strips with a large knife. 

Step 2: Evenly divide the sliced Tanimura & Antle Artisan® Sweet Italian Red Onions, peppercorn, and garlic into three, 10 oz. Mason jars or a glass container with a lid. 

Step 3: In a saucepan, heat the vinegar, water, sugar, and salt over medium heat (you don’t want it to boil). Stir until the ingredients dissolve, about five minutes. Once dissolved, remove from the stovetop and let it cool for a few minutes, then evenly divide the brine mixture into your Mason jars and let it come to room temperature. 

Step 4: Store your red onions in the fridge overnight. Then they’re ready to be added to your favorite recipes.  

How to Store Pickled Red Onions

When stored properly, red onions last up to three weeks in the fridge. Storing onions is incredibly easy. No need to transfer your onions to a new container; keep the onions in the same Mason jars you used for pickling and pop them in your fridge.  If you keep your jars unopened, they can last up to a year. If you decide to stock up on pickled red onions, be sure to check for any discoloration, odd smells, or mold before using them in your dishes.
