Onions and garlic are two basic ingredients in every cuisine. But if not stored properly, they can sprout, mold or soften quickly. Fortunately, there are some simple and effective tricks to keep them fresh for weeks or even months without losing their taste or qualities.
In this article you will learn:
- how to properly store onions and garlic
- where to store them
- what mistakes to avoid
- how to prepare them for winter
- answers to frequently asked questions
Why do onions and garlic spoil?
Both vegetables are sensitive to moisture, excessive heat and lack of ventilation. Among the most common problems are:
- Sprouting - sign that they are kept in an environment that is too warm or bright
- Rotting – occurs due to moisture or storage in closed bags
- mold – due to the lack of air circulation
How do you keep onions and garlic in optimal conditions?
1. Cool, dry and dark place
- Ideal: a well-ventilated pantry, a kitchen cupboard or a mesh basket in a shady corner
- Recommended temperature: 4–10°C
- Avoid direct sunlight and damp spaces (e.g. near the sink or stove)
2. Excellent ventilation
- Keep the onion and garlic in jute bags, perforated bags, cardboard boxes with holes, reed baskets or cotton nets
- DO NOT store them in plastic bags – they retain moisture and promote decay
3. Separation from other vegetables and fruits
- Do not store them near potatoes – they release moisture and gases that accelerate sprouting
- Garlic and onions should be stored separately from each other to avoid cross contamination
Useful tricks for prolonging freshness
Onion:
- Do not clean it until use
- Do not wash it before storage
- If you have peeled onions, store them in an airtight glass jar in the refrigerator (max. 5 days)
Garlic:
- Keep it with everything in the skin
- If you've split a head, wrap the rest in a paper towel and place it in a ceramic container or jar without a lid
- Peeled garlic (individually) can be kept in the refrigerator with a little olive oil (max. 7–10 days)
❄️ What do we do in winter? Longer preservation methods
1. Drying onions and garlic
- Place them in airy layers on newspapers, in well-ventilated, dry spaces without direct sunlight
- In 1–2 weeks they become completely dry and can be put in jute bags
2. Rope braiding (traditional)
- A method used mostly in rural areas – braid onion/garlic tails and hang them in the air
3. Preserving garlic in oil (carefully)
- Peel and chop the garlic, then cover with oil in a sterilized jar
- ⚠️ Store in the refrigerator and consume within 7 days - there is a risk of botulism if left at room temperature
❌ Common mistakes to avoid
| Mistake | Why is it problematic? |
|---|---|
| Storing in the fridge (for whole onions) | Promotes softening and mold |
| Use of plastic bags | Holds moisture, leads to spoilage |
| Storing next to potatoes | Accelerates germination |
| Leave in closed boxes without ventilation | It spoils quickly due to lack of ventilation |
