How to keep fresh vegetables longer? Properly storing your vegetables helps preserve their texture, taste, and freshness while reducing food waste. In this CuisinerTelUnChef guide, discover where to store each vegetable, when to wash them, how to freeze them, and which foods to separate to truly extend their shelf life. The essential principle: adapt the temperature, humidity, and ventilation to each family of vegetables. A crisper drawer is not suitable for everything, and a closed plastic bag is rarely a good idea. The 7 rules for proper storage Do not wash vegetables before storing them, unless you can dry them perfectly. Remove the greens from carrots, radishes, and beets: they draw moisture from the root. Promptly remove damaged parts to limit the spread of mold. Promote airflow with a paper bag, mesh bag, or ventilated container rather than airtight plastic. Avoid overloading the crisper drawer: air must circulate around the vegetables. Apply FIFO rotation: first vegetable bought, first vegetable cooked. Separate ethylene producers from vegetables sensitive to this natural ripening gas. CuisinerTelUnChef Tip Reserve a visible area of the refrigerator for vegetables to be used first. A small "to cook this week" container turns forgotten vegetables into soup, stir-fry, or side dishes instead of letting them end up in the compost. Which vegetables should be stored in the refrigerator? The crisper drawer is particularly suitable for lettuce, spinach, broccoli, cauliflower, green beans, carrots, zucchini, cucumbers, leeks, celery, radishes, asparagus, fennel, and ripe peppers. Store them unwashed, in breathable packaging, using a paper towel if moisture accumulates. Carrots, radishes, and beets Remove the greens as soon as you buy them and store the roots in a perforated bag or a container with a paper towel. As for the greens, they can be cooked quickly as pesto or in soup. Estimated shelf life: 2 to 4 weeks for carrots, a few days for the greens. Lettuce and leafy greens Wash just before use. If the lettuce is already washed, dry it thoroughly and place it in a container with a paper towel. Estimated shelf life: 3 to 7 days. Broccoli and cauliflower Keep them unwashed in a perforated bag and consume them first. Slightly yellowed florets are still usable if they are firm and free of abnormal odors or mold. Estimated shelf life: 5 to 7 days. Zucchini and eggplant Place them in the crisper drawer, away from the coldest areas. Do not wash them before storage and avoid bruising them. Estimated shelf life: 5 to 7 days. Mushrooms Store them in a paper bag or their ventilated carton, never in closed plastic. Only brush them off when you are ready to cook them. CuisinerTelUnChef Tip For tender herbs like parsley and cilantro, place the stems in a glass of water, cover lightly, and change the water every two days. Basil is the exception: keep it at room temperature, never in the cold. Discover all our tips in the aromatic herbs guide. Which vegetables should be stored at room temperature? Potatoes, onions, garlic, shallots, and squash prefer a cool, dry, dark, and well-ventilated place, ideally between 12 and 18°C. Avoid the refrigerator, closed plastic bags, and direct light. Potatoes: cellar or dark cupboard, 2 to 8 weeks. Throw away any that are very green or have large sprouts. Onions and shallots: mesh bag or ventilated basket, separated from potatoes, 1 to 2 months. Garlic: dry and ventilated area, 2 to 3 months. Squash, pumpkins, and butternut squash: dry and tempered room. Tomatoes: at room temperature to preserve their aromas. Only refrigerate them if they are very ripe or if the room is very hot. CuisinerTelUnChef Tip Never store potatoes and onions together. Their moisture and gases accelerate sprouting and rotting. Use two separate baskets, away from light. Ethylene: why some foods must be separated Ethylene is a natural gas that accelerates ripening. Apples, ripe pears, bananas, ripe avocados, ripe tomatoes, and melons produce a lot of it. Broccoli, cabbage, lettuce, spinach, carrots, asparagus, cucumbers, and zucchini are sensitive to it. Place producers in a separate area from leafy vegetables. However, you can use an apple to intentionally accelerate the ripening of a hard avocado, then move the ripe avocado to the refrigerator. Freezing vegetables: the blanching method Blanching stops enzyme action, helps preserve color, and improves texture after thawing. It is especially useful for broccoli, cauliflower, green beans, carrots, peas, spinach, and asparagus. Wash, trim, and cut vegetables into uniform pieces with a kitchen knife on a cutting board. Plunge them into a large pot of boiling water for 2 to 3 minutes. Cool them immediately in an ice water bath. Dry them thoroughly to avoid ice crystals. Spread them on a tray, freeze individually, then transfer to a labeled bag with the date. Vegetable Estimated blanching time Freezer shelf life Broccoli and cauliflower 3 minutes 10 to 12 months Green beans 3 minutes 10 to 12 months Sliced carrots 3 minutes 10 to 12 months Peas 2 minutes Up to 12 months Spinach 2 minutes 10 to 12 months Sliced peppers and onions Not necessary 6 to 12 months Vacuum sealing Vacuum sealing limits contact with air and can be useful for vegetables prepared as part of batch cooking. It does not replace the cold chain: always keep bags in the refrigerator and follow recommended durations. Very watery vegetables, like tomatoes and cucumbers, often lose their texture when vacuum-sealed. Storing aromatic herbs Parsley, cilantro, and chives: stems in a glass of water, light cover, refrigerator. Basil: stems in water, at room temperature, away from direct sunlight. Thyme, rosemary, and sage: dry cloth or ventilated container in the crisper drawer. Freezing: chop the herbs and place them in an ice cube tray with olive oil, then use them in sauces and stews.

They depend on freshness at the time of purchase, temperature, and the state of the vegetable. Mistakes to avoid Washing and then sealing vegetables while still damp. Using an airtight plastic bag that traps condensation. Forgetting the greens on root vegetables. Storing potatoes and onions together. Leaving potatoes in the light, which promotes greening. Freezing without portioning or labeling. Storing a moldy vegetable in contact with others. Putting basil in the refrigerator, where it turns black quickly. Frequently asked questions Should I wash vegetables before storing them? No, it is better to wash them just before use. If you have already washed them, dry them completely before storing them. Why remove the greens from carrots? They continue to absorb water from the root. Remove them upon purchase and use them separately within two or three days. Can tomatoes be put in the refrigerator? Yes, if they are very ripe or if the room is very hot, but room temperature better preserves their flavor and texture. How can I avoid wasting wilted vegetables? Use vegetables that are starting to soften in soup, puree, stir-fries, quiche, or broth. Can you freeze raw vegetables? Some vegetables, like peppers and onions, can be frozen raw. For most others, blanching significantly improves color and texture.
