Certain vegetables are best kept away from the refrigerator, despite what your instincts might tell you.
Special Poll
Refrigeration may seem like the right choice for keeping produce fresh, but for these three common veggies, cold storage can quickly diminish quality, taste, and even nutrition.
- Basil
Basil is notoriously sensitive to cold temperatures. When placed in a refrigerator, this aromatic herb rapidly wilts and turns brown, losing its vibrant color and flavorful oils. Cold air triggers a reaction in basil’s delicate leaves, causing them to shrivel, discolor, and ultimately spoil prematurely.
To keep basil fresh, treat it just like a bouquet of flowers. Simply trim the stems slightly and place the bunch into a glass filled with room-temperature water. Keep the glass on your countertop away from direct sunlight, making sure the leaves remain above the waterline. Refresh the water every two to three days to preserve freshness, flavor, and aroma.
- Potatoes
Whether your potatoes are russets, Yukon golds, or sweet potatoes, the refrigerator is not your friend. The cool temperatures inside a fridge convert potato starches into sugars, altering the potato’s flavor and texture significantly. Instead of fluffy and delicious, refrigerated potatoes can become grainy, overly sweet, or bitter—certainly not the quality you want in your favorite dishes.
Additionally, the FDA explicitly advises against refrigerating potatoes due to a potential health concern. Cold-stored potatoes, when later cooked at high heat, can produce acrylamide—a chemical considered potentially harmful to health.
To store potatoes correctly, place them in a cool, dark, dry spot, like a pantry, basement, or cupboard. Many grocery stores package potatoes in paper bags with ventilation holes, designed to prevent moisture build-up. If you’ve discarded this packaging, use a mesh bag, basket, or bowl that allows airflow. This ensures your potatoes remain fresh and safe to eat.
- Yellow, White, and Red Onions
The common cooking onions—those with the dry, papery skins like yellow, white, or red varieties—should never see the inside of your refrigerator. Cold storage makes these onions soften quickly and leads to early spoilage. They can also absorb unwanted moisture, resulting in an unpleasant taste and mushy texture.
Instead, onions need a cool, airy, dry environment. Store them in mesh bags, paper sacks, or wire baskets. Be cautious not to store onions and potatoes side by side, as onions emit ethylene gas, which can accelerate sprouting in potatoes. Keep onions separate, ideally hanging in a well-ventilated place or stored on a different shelf entirely.
By understanding the proper storage methods for these popular veggies, you’ll enjoy fresher, tastier, and healthier meals—and get the best value from your grocery shopping.
