How long will vegetables stay fresh at room temperature?

Vegetables stay fresh for varying periods of time at room temperature, depending on the type of vegetable and the storage conditions. Here are some general guidelines:

- Fresh leafy greens, such as spinach, lettuce, and arugula, will typically last for 1-2 days at room temperature.

- Cruciferous vegetables, such as broccoli, cauliflower, and cabbage, can last for 2-3 days at room temperature.

- Root vegetables, such as potatoes, carrots, and turnips, can last for up to a week at room temperature.

- Winter squashes, such as butternut squash, acorn squash, and pumpkin, can last for several weeks at room temperature.

- Onions, garlic, and shallots can last for up to 2 months at room temperature.

- Tomatoes will ripen at room temperature, and can last for up to a week.

It's important to note that these are just general guidelines, and the actual lifespan of vegetables at room temperature can be influenced by factors such as the temperature, humidity, and level of exposure to light.

To extend the shelf life of vegetables at room temperature, you can store them in a cool, dark place, such as a pantry or cupboard. You can also wrap them in plastic wrap or place them in an airtight container to help retain moisture.

If you're not sure whether a vegetable is still fresh, it's always best to err on the side of caution and discard it.
