The Best Ways to Store Cut Red Onions for Longer Freshness

Red onions are a staple ingredient in many cuisines around the world. They add color, flavor and texture to dishes such as salads, sandwiches, and burgers. However, storing cut red onions can be tricky as they tend to spoil quickly due to their high water content.

In this blog post, we’ll show you how to store cut red onions properly so that they stay fresh for longer periods of time.

The Best Way To Store Cut Red Onions

1. Keep it Dry

The first step in storing cut red onions is to make sure they are dry before putting them away. Use a clean towel or paper napkins to pat the onion slices dry before storing them.

If you have sliced your onion with a wet knife, rinse the slices under cold water and then pat them completely dry with some paper towels before storage.

Moisture on an onion can cause bacteria growth on its surface which will lead it towards spoilage over time if not dried adequately.

2. Use an Airtight Container

After drying your sliced onion thoroughly put them into an air-tight container – this could be plastic containers or even heavy-duty zipper bags designed for food storage purpose – but ensure there is no air left inside after sealing tightly.

A sealed container helps keep the moisture level balanced and stops any additional moisture from entering in contact with your chopped onions while stored coolly in the fridge or pantry.

You should always avoid using plastic wrap when holding chopped vegetables like garlic/onion since it’s hard to seal tightly enough thus allowing air/moisture inside which will harm freshness within hours particularly during hot summer months.

3: Pick The Right Storage Location

Whether you’re keeping your chopped up red onions refrigerated or at room temperature depends upon how fast you intend consuming them- fridge storage might allow you up to three days of freshness, but the onions will last less time on a countertop.

For short term use, keep them at room temperature for up to 24 hours in a cool dry spot away from any heat sources.

However, if You wish to store cut red onions for longer periods or have leftover slices after using them during food preparation then refrigeration is your best option. Place sealed containers or bags of sliced red onion(s) inside the vegetable crisper section (the coldest area) in your refrigerator until ready for next use.

4: Use Acidic Preservation Methods

If you want to keep cut-up red onions fresh even longer, consider preserving them with an acidic solution made with vinegar and salt combination- this can extend their life by another week easily.

To make this solution mix equal parts of white vinegar and water together along with some salt; start by mixing one tablespoonful of kosher salt into every cup each water/vinegar mixture before pouring it over your freshly-chopped-up onion pieces in an air-tight container.

Conclusion

Now that you know how to store cut red onions properly they should last much longer than they usually would when left out exposed. Remember always try drying chopped vegetables like garlic/onion completely before storing them in air-tight containers/bags either on countertops or refrigerators where possible- also using acidic preservation methods as described above is a great way of extending their lifespan too!
