Squash and pumpkins last the longest in a dry, cool, well-ventilated place and do not need to be refrigerated. The following 25 foods can be kept in the refrigerator, but they don't have to be!
Broccoli can keep on the counter for up to two days, but the vegetable will keep better in the cold. Wrap broccoli in a producer bag upon purchase and refrigerate as soon as you can.
Do carrots need to be kept in the fridge? Carrots do not need to be kept in the fridge, but this is certainly the best place for them. Storing carrots that are fresh here will make them last for 3-4 weeks.
Many fruits and vegetables should only be stored at room temperatures. Refrigeration can cause cold damage or prevent them from ripening to good flavor and texture. For example, pink tomatoes ripen to a better taste and red color if they are left at room temperature.
Whole onions and shallots are best stored in a cool, dry, dark and well-ventilated room. Ideal places include the pantry, cellar, basement or garage. Peeled onions can be stored in the fridge for 10–14 days, while sliced or cut onions can be refrigerated for 7–10 days.
Don't store potatoes in the fridge.
Raw potatoes have lots of starches, and the cold temperatures can turn the starches into sugars. This can make your potatoes turn sweeter and darker during cooking.
Store fresh cauliflower heads in a loosely closed or perforated plastic bag in the refrigerator. Cauliflower needs air circulation, so don't seal or knot the bag closed. (If you bought a plastic-wrapped head of cauliflower from the grocery store, just loosen up the knot.)
If properly stored, zucchini will last up to a week. The best way to store zucchini is in the refrigerator, preferably in the crisper drawer where humidity is kept to a minimum.
Lettuce is particularly perishable, compared to many other vegetables. You will get a considerably longer storage lifetime if it is refrigerated, rather than kept at room temperature.
Cucumbers – Cucumbers do best stored at room temperature rather than in the refrigerator. They are also highly sensitive to ethylene and should be kept away from bananas, melons, and tomatoes. Eggplant – Best stored at room temperature; refrigerating eggplant can make it spoil quickly.
In the United States, fresh, commercially produced eggs need to be refrigerated to minimize your risk of food poisoning. However, in many countries in Europe and around the world, it's fine to keep eggs at room temperature for a few weeks.
Most vegetables, like carrots, potatoes, broccoli, cabbage and celery should be stored in a plastic bag or container in the crisper of your fridge. Mushrooms are best stored in a paper bag. Vegetables should be stored in a different part of the fridge than fruit. This will prevent them from ripening too fast.
Tomatoes contain an enzyme that reacts to cold temperatures and causes its cell membrane to break down, leaving you with a piece of fruit that's mushy and mealy. "You're essentially zapping flavor and texture from a tomato when you refrigerate it," says Gregory Lofts, deputy food editor at Martha Stewart Living.
Ripe tomatoes should still be kept at on your counter, uncovered, if you are going to enjoy the tomato in the next day or two. But any longer than that – the recommendation is to refrigerate. A so-so tomato is much better than a rotten, moldy tomato. Refrigeration will slow down the decay.
On your next shopping trip to Market Basket, notice how apples are displayed. They are unrefrigerated because apples do not need refrigeration until they began to soften slightly. Apples should be stored unrefrigerated for about 7 days after purchase. Apples refrigerated too soon lose flavor and sweetness.
Your refrigerator is the best place to keep fresh grapes. They thrive at about 30-32 degrees Fahrenheit with 90-95% humidity, so go ahead and throw them in the back of your crisper drawer (it's usually the coldest place in the fridge).
Put simply, peppers should always be kept in the refrigerator. However, if an uncut pepper is left out for a few hours or even overnight, it will probably not spoil. A pepper's skin will keep the softer inner flesh protected from drying out and beginning to rot.
