National Acorn Squash Day Date in the current year: September 7, 2025

Although acorn squash is considered a winter squash because it is harvested and eaten when mature, it is actually the same species as summer squashes, such as yellow crookneck squash and zucchini. It is so named because its shape actually resembles that of an acorn. Acorn squash is typically dark green, although golden yellow, white, and multicolored varieties also exist.

Acorn squash is widely used in the kitchen. It is rich in potassium and dietary fiber, and also contains vitamins B and C, manganese, and magnesium. Acorn squash can be baked, sautéed, steamed, or microwaved. It is sometimes stuffed with meat, rice, or vegetables.
