Red, white, green, or yellow onions—if not stored properly, they spoil and sprout quickly, leading to waste. Fortunately, as a seasoned home gardener and kitchen expert, I've found a reliable, easy method using perforated kraft paper bags to keep them fresh for months. Here's how:
1. Get kraft paper bags like these.
2. Punch holes using a hole punch. No hole punch? You can find one here. To save time, fold the bag into thirds and punch two rows of holes:
3. Fill halfway to allow air circulation, fold the top, and secure with a paper clip.
4. Store bags in a kitchen drawer or closet shelf, spaced apart for airflow.
This technique keeps onions fresh for 3 months post-harvest or purchase. Skeptical? Try it yourself. Here's a heap of garden onions after 3 months in a ventilated bag—impressive, right?
It works for spring onions, sweet Cévennes onions, white, yellow, or red varieties, Lézignan onions, shallots, and garlic. Label bags with a marker for easy identification. Reuse bags multiple times.
- Keep in the darkest spot possible, away from light.
- Ideal temperature: 18-20°C; a cool cellar is perfect.
- Avoid the fridge—cold softens them and they taint other foods.
- Never use plastic bags; poor airflow causes sprouting and rot.
- Don't store near potatoes; their gases speed spoilage.
- Inspect for damage before bagging; use damaged ones immediately to avoid contamination.
- Opt for larger bags for better air volume—a few onions in a big bag is ideal.
