Here's all you need to know about this low-cal veggie, including how to pick and prep it, and the best ways to cook it. Plus get top-rated recipes for putting your zucchini stock to good use.

How to Pick and Store Zucchini

Zucchini grown quickly, and they can become enormous if left unharvested. Leave zucchini on the vine too long, and the flesh becomes stringy, tough, and bitter tasting. Smaller zukes are typically the tastiest and most tender. They should be plump and firm without blemishes or soft spots and have a decent weight to them. Larger zucchini are good candidates for stuffing or turning into zucchini relish.

Zucchini are fairly delicate veggies. Store them in the refrigerator -- and if you have an abundance from the garden, it's okay to freeze them. To freeze zucchini, first bring a pot of salted water to boil; slice the zucchini in half and quickly blanch them for 2 minutes; then dunk them in ice water, pat dry, and store in the freezer in plastic freezer bags.

Zucchini Nutrition

This long, slim green veggie looks a little like a smooth cucumber with paler green skin. Because zucchini are mostly water (more than 90 percent!), they're very low calorie. Nutritionally, they feature fiber, along with vitamin C and potassium.

Do You Peel Zucchini?

You'll get the most health benefits if you eat the colorful skin, which holds the healthy carotenoids. Zucchini skin is soft, thin, and perfectly edible, so don't peel it off.

How to Cook Zucchini

Mild-flavored zucchini is something of a blank canvas. Like tofu, it tends to take on the flavor profile of the sauces and spices that accompany it. That could be why zucchini is one of the most versatile vegetables. You can grill, sauté, steam, stew, or bake zucchini with delicious results.

How to Sauté Zucchini

Remember, zucchini are mostly water. So when you cook them, you'll find they release a lot of moisture. To remove excess water, you can salt sliced zucchini like you would eggplant. Set the slices aside in a colander to allow the salt to draw water from the flesh. It takes about 12 to 15 minutes. Once you've prepped your zucchini, use this simple method for sautéing zucchini:

  1. Add oil or butter to a skillet over medium heat.
  2. Add the sliced zucchini to the skillet, stirring occasionally, until veggies are tender.
  3. Add any seasonings such as garlic, salt, and/or pepper. Stir for an additional minute and remove from heat.

Can You Freeze Zucchini?

Absolutely, you can freeze zucchini. In fact, it's a great way to save some of your bounty when you cannot possibly cook and eat it all before the veggies start to go bad.

How you'll freeze zucchini depends on what you plan to do with it. For quick side dishes and skillet meals, slice or chop the zucchini. Blanche it in boiling water for one minute. Then scoop the zucchini out of the pan and into a bowl of ice water. (This helps stop the cooking process.)

If you're planning to save zucchini for future zucchini breads or brownies, go ahead and shred the zucchini. Blanche these shreds, too, but for only about 20 seconds. Then drain and dunk them in an ice cold bath.

To actually freeze the zucchini, you'll want to pour out the rounds, pieces, or shreds onto a baking sheet and into a single layer. Freeze until hard, or about 24 hours. Then scoop the zucchini into zip-top bags or freezer containers, and put them back in the freezer. Now, you'll have fresh zucchini waiting on you when you need it, even if your garden is done for the year.
