Acorn Squash: A Comprehensive Guide
Introduction & Overview
Acorn squash (Cucurbita pepo) is a winter squash known for its distinctive ridged shape and nutty, mildly sweet flavor. Despite its classification as a winter squash, it belongs to the same species as summer squash like zucchini. Native to North and Central America, acorn squash has been a staple in indigenous diets for centuries. Today, it is widely cultivated and enjoyed worldwide.
Common Varieties:
• Green Acorn Squash – The most common type with dark green skin and deep ridges.
• Golden Acorn Squash – Features a bright yellow-orange exterior with a sweeter taste.
• White Acorn Squash – Creamy white in color, with a slightly milder flavor.
Seasonality & Availability
Acorn squash is harvested in late summer through early fall and is available throughout the winter. It is commonly grown in the United States, Mexico, and Canada. The flavor and texture of acorn squash improve with storage, as starches convert into natural sugars over time. It is available fresh in most supermarkets and can also be found frozen or canned in pureed form.
How to Choose the Best & Freshest
• Look for squash that is heavy for its size, indicating high moisture content.
• The skin should be firm, dull, and free from soft spots or blemishes.
• A dark green skin with a bright orange patch is a sign of ripeness.
• Avoid squash with wrinkled skin or excessive surface cuts, as this indicates deterioration.
Storage & Shelf Life
• Store whole acorn squash in a cool, dry place (50-55°F) for up to 2-3 months.
• Once cut, wrap tightly and refrigerate for up to 5 days.

How to Prepare Acorn Squash Like a Chef
1. Wash and Dry: Before cutting, thoroughly rinse the squash under running water to remove any dirt. Dry it completely to prevent slipping while cutting.
2. Stabilize the Squash: Since acorn squash has a rounded shape, place a damp towel under the cutting board to prevent movement.
3. Cut Safely: Use a sharp chef’s knife. If the squash is too hard to cut, pierce it with a knife and microwave for 2-3 minutes to soften.
4. Halving the Squash: Trim both ends slightly to create flat surfaces, then carefully slice the squash in half through the stem.
5. Remove the Seeds: Use a sturdy spoon to scoop out the seeds and fibrous strands. The seeds can be roasted for a crunchy snack.
6. Peeling (Optional): The skin becomes tender when roasted, but if peeling is needed, use a sharp vegetable peeler or paring knife.
7. Cut into Desired Shapes: Depending on the dish, cut into wedges, cubes, or slices.
8. Season & Cook: Drizzle with spices, herbs, and oil-free marinades before roasting, steaming, or sautéing.
