15 Popular Food Items You Should Not Refrigerate
Think the fridge is the ultimate food saver? Think again! While we often assume refrigeration keeps everything fresher for longer, certain foods lose their flavor, texture, or quality when chilled. Tomatoes turning mealy and olive oil solidifying are just a few examples of how refrigerating certain items can do more harm than good.
Research shows that foods like potatoes and melons retain more nutrients when kept at room temperature (USDA). Want to keep your food tasting its best and lasting longer? Let’s shake up your storage game with 15 everyday items that are way better off outside the fridge!
Potatoes
Refrigerating potatoes causes their starches to convert into sugar, producing an overly sweet and gritty texture when cooked. The USDA advises storing them in a cool, dark place like a pantry, ideally at 42-55°F, to maintain their quality and nutritional content.
The warmer the temperature, the greater the potential for sprout development. The cooler the temperature, the greater the increase in sugar concentration and the darker the fry color.
Tomatoes
Cold temperatures damage tomato cell walls, making them mealy and dulling their flavor. A study by the Proceedings of the National Academy of Sciences found that refrigeration reduces the volatile compounds responsible for a tomato’s taste.
Chilling tomatoes at temperatures below 12 degrees Celsius results in fruits that are relatively fresh but insipid. Store them at room temperature to preserve their juiciness and flavor.
Onions
Storing onions in the fridge can cause them to become soft, soggy, and spoil faster. They also release gases that can affect nearby produce. The ideal temperature to store onions is around 45 to 55 degrees Fahrenheit.
A cool, dry, dark, and well-ventilated place, like a pantry or cellar, is best. You can store onions in a perforated basket or bin in a kitchen cupboard.
Garlic
Refrigerating garlic can cause it to sprout, lose flavor, and spoil faster. Keep garlic in a well-ventilated container at room temperature to extend its shelf life. Properly stored, it can last up to 2-3 months.
Bread
Cold air dries out bread, making it stale faster than if left at room temperature. A study by the Journal of Food Science found that refrigeration accelerates the staling process by retrograding starch. Store bread in a breadbox or tightly sealed bag, and freeze it if long-term storage is needed.
Bananas
Refrigerating bananas slows the ripening process but can cause the peel to turn black and affect the fruit’s texture. Instead, keep bananas on the counter until they’re ripe. To extend their life, peel and freeze them for smoothies or baking.
Coffee Beans
Refrigerating coffee beans exposes them to moisture and odors, which can degrade their flavor. The National Coffee Association recommends storing beans in an airtight container in a cool, dark place to maintain their aroma and quality.
Honey
Honey crystallizes faster in cold temperatures, making it harder to use. Since it’s naturally antimicrobial and has an indefinite shelf life when sealed, the best way to store honey is in a tightly closed jar at room temperature.
Olive Oil
Cold temperatures cause olive oil to solidify, forming waxy clumps that take time to dissolve. Store olive oil in a dark cabinet, away from heat and light, to preserve its flavor and health benefits.
Unripe Avocados
Refrigerating avocados halts ripening, leaving you with underripe fruit that may never soften properly. Keep avocados at room temperature until they’re ripe, then refrigerate for a few extra days if needed.
Melons (Uncut)
Whole melons, such as watermelon, cantaloupe, and honeydew, lose some antioxidants when refrigerated. According to the USDA, melons stored at room temperature maintain their nutritional content better. Once cut, they should be refrigerated and consumed within 3-4 days.
Winter Squash
Butternut, acorn, and other types of winter squash lose flavor and firm texture when stored in the refrigerator. Instead, keep them in a cool, dry place like a pantry or cellar at temperatures around 50°F (10°C), where they can last for several months without spoiling.
Peanut Butter
Refrigerating peanut butter can make it difficult to spread and is often unnecessary, as most brands contain preservatives to maintain freshness.
The USDA says unopened peanut butter can be stored in a cool, dry place for 6 to 9 months, and opened peanut butter can be stored for 2 to 3 months. Keep it in a pantry at room temperature, and stir natural varieties regularly to prevent oil separation.
Chocolate
Cold temperatures can cause chocolate to “bloom,” forming a white coating from sugar or fat rising to the surface. To keep chocolate at its best, store it in a cool, dry place with a temperature of around 65-70°F, which helps maintain its appearance and flavor.
Ketchup
Ketchup doesn’t require refrigeration due to its high acidity, which inhibits bacterial growth. The acidity comes from the tomatoes and vinegar they contain. The acidity of ketchup is typically between 3.60–3.90.
Most commercial brands contain preservatives that keep them stable for weeks or even months after opening, allowing them to remain in the pantry. Once opened, the versatile condiment is safe to eat for about six months, according to the U.S. Department of Agriculture.
