Guide to Winter Squash: How to Buy, Store, and Cook

Let’s talk about winter squashes. The first thing you should know is that the term ‘winter squash’ is a bit of a misnomer. You see, these thick-skinned vegetables are usually harvested in late summer and autumn, but keep well through the cold winter months — earning them their name.

Since pumpkins, acorn squash, and butternut squash are often the most common squashes to find at a grocery store, our Guide to Winter Squash is based on those 3 types. However, the buying, prepping, and flavor-pairing tips we put together will apply to almost all winter squash varieties. Just double check cook times when working with types other than acorn, butternut, and pumpkin.

Winter Squash Basics

Winter squashes have a tough skin and come in a variety of sizes and colors. They are packed with vitamins and minerals and have a flavor range of mild to sweet. Here are a few of the most common winter squash varieties in the U.S. so you can understand some of their basic differences:

• Acorn: Named for its acorn-like shape, it is smaller with sweet flesh and comes in orange, yellow, and green.
• Buttercup: Not to be confused with butternut squash, this green-skinned squash is turban-shaped and has a very mild flavor after cooking.
• Butternut: Bulb-shaped with tan skin, this variety is one of the most common because it is so versatile with it’s thin skin and unimposing flavor.
• Carnival: This variety comes in many shapes and colors. Although it makes adorable fall decor, its sweet flesh can also be cooked in several delicious ways.
• Delicata: Oblong and football-looking, this squash is yellow or orange and has a taste almost like a cross between sweet potato and squash. It has thin skin so you don’t need to bother with any peeling, and you can eat the skin!
• Dumpling: Whitish-yellow and green, this squash is compact and has flesh that tastes almost like a sweet potato.
• Kabocha: Since ‘kabocha’ is the Japanese word for winter squash, that means there are several types. The most common ones in the U.S. have green or grayish skin and are often sold in hunks due to its tough skin and large size. Once cooked, its flesh is a bit like velvet.
• Spaghetti: Light yellow and football-shaped, it is often roasted whole before the flesh is pulled apart with a fork to resemble pasta.

What to Look For in a Winter Squash

What to look for: When shopping for winter squash, listen for a hollow sound when you tap it. If the stem is still attached, it should be firm and intact. Remember that some winter squash varieties have stripes, warts, or naturally splotchy coloring, and that is perfectly fine! Don’t fear the warts.

What to avoid: You should keep an eye out for actual blemishes and soft spots, which are signs that a squash is rotting. If you see shriveling or any broken skin, run the other way.
