The Ancient Roots of Squash: A Journey Through History
Squash, a member of the Cucurbita genus, boasts a history stretching back millennia, deeply entwined with the agricultural evolution of the Americas. Archaeological evidence suggests squash cultivation in Mesoamerica (present-day Mexico) as early as 10,000 years ago, making it one of the earliest domesticated crops. It was a cornerstone of the ‘Three Sisters’ agricultural system, alongside maize (corn) and beans, providing essential nutrients and contributing to the dietary stability of indigenous populations. These early civilizations cultivated both summer and winter squash varieties, adapting them to local climates and culinary traditions.
European explorers later brought squash to the Old World, leading to its widespread adoption and adaptation across various cultures. Today, squash is a global staple, with diverse varieties reflecting regional preferences and unique culinary traditions. From the delicate courgette/zucchini of the Mediterranean to the hearty pumpkins of North America, the story of squash is a testament to its adaptability and enduring appeal.
Mastering the Art of Squash: Essential Cooking Techniques
Squash’s versatility shines through in the myriad of ways it can be cooked. Here’s a guide to popular cooking techniques, ensuring tender, flavourful results every time:
-
How to Cook Squash (General Overview): Begin by thoroughly washing the squash. Then, cut it open and scoop out the seeds. (Remember to save the seeds from winter squash for roasting!) Depending on the variety and your recipe, you may need to peel the squash. Cook until tender; the flesh should be easily pierced with a fork or knife.
-
How to Prepare Squash for Cooking:
- Summer Squash (e.g., courgette/zucchini, yellow squash): The skin is typically edible, so simply wash and trim the ends. Slice, dice, or grate as needed.
- Winter Squash (e.g., butternut, acorn, pumpkin): The thick skin is usually removed. See instructions in “Ingredient Preparation” below.
-
How to Grill Squash: Prepare the squash as described above. Toss diced or sliced squash with olive oil, salt, and pepper. Grill over medium heat, turning occasionally, until tender and slightly charred (approximately 10-15 minutes).
-
How to Bake Squash: Preheat your oven to 200°C (180°C fan/Gas Mark 6). Cut the squash in half lengthwise (or into cubes for easier cooking). Scoop out the seeds. Drizzle with olive oil, season with salt and pepper, and bake until tender, usually 30-60 minutes depending on the size and variety.
-
How to Sauté Squash: Dice or slice squash. Heat olive oil or butter in a pan over medium heat. Add the squash and cook, stirring occasionally, until tender and lightly browned (approximately 8-12 minutes). Consider adding herbs, spices, or other vegetables during the last few minutes for extra flavour.
Squash Preparation: From Farm to Table
Proper preparation is key to unlocking the best flavour and texture from your squash. Here’s how to handle different types:
-
How to Cut Squash:
- Summer Squash: Trim the ends and slice, dice, or cut into rounds as required.
- Winter Squash: Place the squash on a stable cutting board. Use a sharp, sturdy chef’s knife to cut it in half lengthwise. Scoop out the seeds and stringy fibres with a spoon. Always use caution when cutting! A rocking motion can help. As a tip, microwaving the whole squash for a few minutes can soften the skin slightly before cutting, especially for harder varieties.
-
How to Peel Squash (if applicable): After cutting, you can peel winter squash. Use a vegetable peeler to remove the skin, being careful of the firm flesh. For some varieties, like butternut, a vegetable peeler works well. For others, a paring knife might be necessary. Pre-roasting the squash for a bit can also help to peel the skin.
-
How to Dice Squash: After peeling (if necessary) and removing seeds, cut the squash into thick planks. Then, slice the planks into strips and, finally, dice the strips into cubes of the desired size.
-
How to Mince Squash (less common, but possible): Summer squash can be minced after washing and trimming the ends. It’s not typically done with winter squash, which has a firmer texture and is usually diced or sliced.
Preserving the Harvest: Proper Squash Storage
Proper storage is crucial for maintaining the freshness and extending the lifespan of your squash:
-
How to Store Squash:
- Whole Squash: Store whole, uncut winter squash in a cool, dry, dark place (e.g., a pantry or cellar) for several months. Summer squash should be refrigerated.
- Cut Squash: Wrap cut winter squash tightly in plastic wrap or place it in an airtight container and refrigerate. Use within 3-5 days. Refrigerate cut summer squash, and use it within 2-3 days.
-
How long does squash typically last under different storage conditions?
- Whole Winter Squash: Up to 3 months (or even longer) at room temperature in ideal conditions.
- Whole Summer Squash: Up to a week in the refrigerator.
- Cut Winter Squash: 3-5 days in the refrigerator.
- Cut Summer Squash: 2-3 days in the refrigerator.

Cleaning and Ripeness: Tips for Choosing and Preparing Squash
Here are some tips on choosing and preparing the perfect squash:
-
How to wash squash properly to remove dirt and contaminants: Rinse the squash thoroughly under cold running water. Use a vegetable brush to scrub the surface, especially the crevices and any areas with dirt. For summer squash, washing is usually sufficient. For winter squash, even after peeling, ensure you wash the flesh thoroughly to remove any remaining dirt or residue.
-
How to tell if squash is ripe:
- Summer Squash: Choose squash that are firm to the touch, with smooth, unblemished skin. They should be relatively small for their type, as they can become seedy and less flavourful as they grow larger. The skin should be easily pierced with a fingernail.
- Winter Squash: Look for squash that have hard, dense skin, free from soft spots, cracks or bruises. The stem should be firm and dry. Tap the squash; it should sound hollow. The colour should be vibrant and characteristic of the variety.
-
When is squash in season?
- Summer Squash: Peak season is typically from late spring to early autumn (May to September).
- Winter Squash: Peak season is from late summer through autumn and early winter (September to December). They often keep well, so you may find them available later.
