What’s the difference between squash and zucchini?

The main difference between zucchini and squash is their color. It’s usually the simplest way to tell them apart!

Zucchini are typically a dark green color and sometimes have dark and light green variations on the same vegetable. Squash is usually yellow. It can be golden to bright yellow in color and usually has a softer more easily pierced skin.


Another differentiating factor is the shape. Squash are usually more bulbous on the bottom while zucchini are more straight and usually are more uniform in size throughout. They may have a slight taper towards the top but typically do not have a curve or a bulbous bottom.

Looking for kitchen essentials for preparing a simple dinner casserole?

When you head into the kitchen to make some of these great recipes you’ll want to have the best tools on hand.


I like half sheet baking pans that are quality (hello no noisy pops or sloshed cookie dough from twisting), I line my cookie sheets with silicone baking mats. These are great for all kinds of baking and not just cookies! My husband loves them for making biscuits, pizzas, and more!


Of course mixing bowls, a mixer, spatula, and some whisks should be on your list if you don’t have ones that you love. I also like to have a set of cooling racks so that my recipes can properly cool before they’re scarfed down by my family!
