To avoid waste and savor them for longer, you need to know how to store sweet onions. This will help you save money and ensure you always have them ready to use.

This article will take you through the different ways to store sweet onions and keep them fresh for months.

Tips for Storing Sweet Onions

Sweet onions are a key ingredient in many recipes. So, it makes sense to keep some in hand at all times. Here are simple sweet onion storage tips to extend their shelf life.

Store Them Whole

Whether you have Vidalia onions, red onions, or even potatoes, the best way to enjoy them longer is by storing them whole. Their papery covers serve as natural protection from outside elements.

Whole onions should be stored in a well-ventilated container such as a mesh basket, open paper bag, or perforated plastic sack.

Ensure Proper Air Circulation

Good air circulation is key to preserving Vidalias as any moisture trapped around the onions will promote rot. Place each bulb individually in a single layer, wrapped separately in paper towels. The paper towels help to absorb moisture.

You can also store your Vidalia onions in the legs of clean sheer pantyhose. Tie a knot between each bulb and hang them in a cool, dry, well-ventilated place.

Avoid Direct Sunlight

Light and moisture lead to mold and sprouting of onions and potatoes. So ensure you store your bulbs of onion in a dry, well-ventilated basket or bin away from direct sunlight.

Store at Room Temperature

Place them in a dry, dark spot like inside a cabinet or the back of your pantry. Sunlight affects humidity and temperature, causing onions to go bad. Ideally, you should place them in a brown store at room temperature.

Refrigerate Sweet Onions

Alternatively, you can store the whole bulbs in the refrigerator’s veggie bin. First, wrap each bulb of onion individually in a paper towel to help absorb moisture.

Then, place them in the crisper with vents closed. Frozen Vidalias can keep for months.

Note, do not store your sweet onions with potatoes, which makes them go bad faster. When stored properly, whole sweet onions can last up to 2 months.

How to Store Peeled Sweet Onions?

Peeling sweet onions significantly reduces their shelf life. Once peeled, sweet onions should be stored in the fridge in an airtight container. Ensure the fridge is set to 40 degrees F. or below. These onions can last 10 to 14 days in the refrigerator.

How to Store Sliced, Diced, or Chopped Onions?

Most of the time, you want your onions ready for whenever you want to prepare a meal. So here are a few ways to preserve sweet onions that have already been chopped or diced.

Refrigerate Sweet Onion

It is common practice for most people to slice a whole onion bulb in half to use part of it. sweet onions are too yummy and valuable to discard. To store, simply chop sweet onions. The freshly cut onions require a lack of air to stay fresh.

Store the wrapped onion in a darker fridge area to prevent sprouting. A plastic bag can substitute a plastic wrap but make sure it is airtight. Store them in the fridge for up to 10 days.

Note: always check refrigerated onion for discoloration and contamination before use to ensure optimum freshness.

For long-term use, store your sliced, shopped, or cut onions in freezer containers in the freezer. Frozen onions can last for 3 to 6 months and are best used in stews. Soups and casseroles.
