What Is Acorn Squash?

Available year-round and at peak production from September through March, acorn squash is a sought-after vegetable that’s known for its nutty flavor. Plus, it’s filled with vitamins A and C, antioxidants, fiber, and potassium. Just like other winter squash such as butternut, delicata, buttercup, and spaghetti squash, it has a hard skin. But don’t let that hard skin scare you away—after you bake it, the skin will become soft and easily separate from the flesh, so there’s no need to worry about peeling it. The squash’s dense texture and firm flesh will hold up well in your favorite squash recipes. Its small size makes it easy to cook it in a slow cooker, puree it for soups, add it to salads, and even create an edible bowl by filling it with cooked rice or stuffing. And don’t forget about its seeds—try roasting squash seeds to make a nutritious snack.

How to Select Acorn Squash

Choose firm squash that are heavy for their size—the heavier the squash, the denser the flesh inside. Look for those with smooth, unblemished skin with a stem still attached. If it has a soft spot, put it back on the shelf because you don’t want a rotting squash. Also steer clear of squash that has a lot of orange coloring since they tend to be tough and fibrous. Make sure you buy enough acorn squash for your recipe—keep in mind that a 2-pound squash will make 6 cups of cubed squash.

How to Store Acorn Squash

When you find a perfect squash in the grocery store or in your garden, you can store it whole in a cool, dry place between 50°F and 60°F up to 2 months. Be sure to refrigerate cut squash, wrapped in plastic, up to 4 days.
