In this article, we highlight the differences between acorn squash and butternut squash, and how they both can be used in the kitchen. We also provide some recipe ideas to get you started.

Differences Between Acorn Squash and Butternut Squash 

1. Acorn vs. Butternut Squash: Shape and Appearance

Acorn squash (Cucurbita pepo var. turbinata) is usually dark green with deep ridges and looks like an acorn. There are also some varieties with orange or white skins. It’s easy to spot in the grocery store, with its compact, round shape.

Acorn squash has a more delicate skin and doesn’t store as long as butternut squash. If stored in a cool, dark place, acorn squash will last up to a month.

Butternut squash, on the other hand, can last up to three months. It’s thicker skin and dense flesh make it more durable. Consider freezing squashes to extend its shelf life.
