Curing and Storing Onions and Garlic: The Ultimate Guide for Long-Lasting Flavor
Onions and garlic are kitchen staples that every home cook and gardener treasures. They add incredible depth to meals, have powerful health benefits, and—when properly cured and stored—can last for months without losing flavor or quality. If you’ve recently harvested onions and garlic from your garden or purchased them in bulk, knowing how to cure and store them properly is crucial for preventing rot, sprouting, or mold.
In this comprehensive guide, we’ll walk you through everything you need to know about curing onions and garlic, including when to harvest, how to prepare them for storage, and the best ways to keep them fresh for long-term use.

Why Curing is Essential for Onions and Garlic
Curing is the process of drying out the outer layers and necks of onions and garlic after harvest. This step is critical because it allows excess moisture to evaporate, toughens the papery skin, and seals the bulb, protecting it from bacteria, mold, and rot. Without curing, your harvest will spoil quickly and won’t be suitable for long-term storage.
Both onions and garlic are harvested in late summer, but proper curing conditions can ensure they last well into winter—or even spring.

When to Harvest Onions and Garlic
The timing of your harvest directly impacts how well your onions and garlic will store.
Onions:
Harvest onions when 70–80% of the tops have naturally fallen over and started to dry.
Gently lift them out of the soil using a garden fork, being careful not to puncture the bulbs.
Garlic:
Garlic is typically ready to harvest when about 40–60% of the leaves have turned brown but 3–4 green leaves remain.
Carefully dig up the bulbs with a fork or spade rather than pulling on the stalks, which can damage the neck.
Both crops should be handled gently to avoid bruising, as damaged bulbs are more prone to spoilage during storage.

How to Cure Onions
Curing onions is straightforward, but it does require patience and proper conditions.
1. Brush Off Soil:
Gently remove excess dirt from the bulbs, but don’t wash them with water. Any moisture will slow down the curing process.
2. Lay Out to Dry:
Spread onions out in a single layer in a dry, airy, and shaded location. An open shed, barn, porch, or covered patio works well.
3. Maintain Airflow:
Ensure good ventilation by placing the onions on a screen or mesh surface rather than solid flooring. This allows air to circulate around each bulb.
4. Curing Duration:
Let the onions cure for 2–4 weeks until the necks are completely dry and papery, and the outer skins are crisp. The roots should also be dry and brittle.
5. Trim and Store:
Once cured, trim the roots and cut the tops to about 1 inch, or leave the tops attached if you plan to braid them.

How to Cure Garlic
Garlic follows a similar curing process but requires slightly more attention to avoid mold and sprouting.
1. Clean the Bulbs:
Shake off soil, but don’t remove the papery skins or wash the garlic.
2. Hang or Lay Flat:
The traditional method is to tie garlic stalks into bundles of 6–8 and hang them in a well-ventilated, shaded area. Alternatively, you can lay them flat in a single layer on racks or screens.
3. Curing Duration:
Garlic generally takes 3–4 weeks to cure. The skins will become papery, and the roots will dry completely.
4. Trim and Prepare for Storage:
Once fully cured, cut the roots short and trim the stems down to 1 inch unless you prefer to braid your garlic for storage.

Best Storage Conditions for Onions and Garlic
Once cured, proper storage is key to keeping onions and garlic fresh for months.
Temperature: Store at 32–40°F for the longest shelf life. A cool pantry, root cellar, or basement is ideal. Avoid refrigeration for long-term storage, as it can cause sprouting.
Humidity: Low humidity (65–70%) is essential to prevent mold and rot.
Light: Keep them in a dark space to avoid sprouting.
Containers: Use mesh bags, baskets, or breathable crates. Avoid plastic bags, which trap moisture and lead to decay.

How Long Do They Last?
Onions: Properly cured and stored onions last 3–6 months. Sweet onions have higher water content and store for a shorter time (1–2 months), while storage onions last much longer.
Garlic: Well-cured garlic can last 6–8 months in ideal conditions, though softneck varieties typically last longer than hardneck types.

Tips to Prevent Spoilage
Check Regularly: Inspect your stored onions and garlic every few weeks. Remove any bulbs that show signs of sprouting, softness, or mold to prevent them from affecting the rest.
Separate Crops: Store onions and garlic separately if possible. Onions emit moisture and gases that may shorten garlic’s shelf life.
Avoid Plastic or Closed Containers: Lack of ventilation is the fastest route to mold. Always keep them in breathable storage options.
Use Imperfect Bulbs First: Any that have slight bruising or cuts should be used promptly, as they won’t store well.

Bonus: Braiding Garlic and Onions
Braiding garlic and onions not only looks rustic and beautiful but also allows better airflow around each bulb. To braid garlic:
1. Use softneck garlic varieties for best results.
2. Start by laying three bulbs side by side, then weave additional stalks in, alternating sides, while tightly crossing each stalk.
3. Hang the braid in a cool, dry location for easy access in the kitchen.
Onions can also be braided using the same method with their dried tops intact.
