Everything you need to know about your favorite summer squash, zucchini! Varieties, how to buy it, how to store it, and nutrition information.

My weather forecast reads 102 degrees F for the next eight days. It’s safe to say, summer is here. And with summer comes everyone’s favorite summer squash…zucchini! As with just about every other “vegetable” that has been an Ingredient of the Week here on Live Eat Learn, it’s not actually a vegetable. It’s a fruit. Like do real vegetables even exist? Ugh. We’re calling it a vegetable!

Did you know they can grow to be REALLY BIG? The biggest one recorded was 7 feet 10 inches! If left to its own accord, your average zucchini would grow to be as big as a baseball bat. But it wouldn’t taste so swell. Bigger zucchinis are tough and fibrous, so we pick them when they’re small (about 7 to 9 inches). Oh, also! They have a big, golden flower that’s edible (you know how I love edible flowers).

And everyone likes themselves some food history right? Well all squash plants originate in the Americas. When Europeans discovered these starchy plants, they brought them back home and started growing and cultivating them there. It was in Italy that the modern day zucchini finally came to be, where it was dubbed zucchino (little squash). The zucchini made its way back to America in the 1920s, where it was ignored by the average consumer for about 50 years. Poor zucchini. But it’s okay, we’ve got an entire week dedicated just to you, zucchini!

How to buy good zucchini

Zucchini grows best in temperate climates…not too hot, not too cold. While you can get it just about year-round, they’re out in full force during the summer months. As I mentioned earlier, bigger is not always better when it comes to zucchini. Generally, smaller zucchinis are less bitter, have softer seeds, and thinner skins. You’ll want to choose one with smooth skin that’s blemishes-free.

Types of zucchini

There aren’t many variations of zucchini, probably because anything varying far from your everyday  zucchini gets classified as another type of squash. The breakdown is pretty simple:

• Plain ‘ole Regular Zucchini: green
• Golden Zucchini: gold
• Globe Zucchini (8-Ball): round and softball-sized

How to store zucchini

• Be gentle! Small nicks and scratches in the skin can cause your zucchini to deteriorate quickly.
• Fresh zucchini can be stored for about a week. Store it in a cool, dry place (not the fridge!), and only wash it right before using.
• Freeze zucchini by chopping it into slice, steaming or boiling for about 3 minutes, then place it in an airtight container. Frozen zucchini is good for about a year.
