Appearance and Identification
Summer squashes can be identified by their vivid colors and unique shapes:

- Yellow Squash: Bright yellow; may be straightneck (evenly thick) or crookneck (curved and bulbous at the bottom); glossy skin.
- Pattypan Squash: Small, round, with scalloped edges; pale green, yellow, or white.
- Other varieties in the summer squash family may display combinations of these characteristics, but zucchini and yellow squash are the most commonly confused.
Nutritional Comparison
Both summer squash and zucchini are low-calorie and water-rich, making them excellent choices for light summer meals.
- 1 cup of raw sliced squash or zucchini contains only about 20-25 calories. Boiled slices provide around 30-35 calories per cup.
- Both are good sources of dietary fiber, vitamin C, vitamin B6, folate, magnesium, potassium, and manganese.
- Zucchini contains more vitamin K and riboflavin, as well as higher levels of beta carotene, lutein, and zeaxanthin—compounds beneficial for eye health.
- Yellow squash tends to be higher in copper.
- All types offer antioxidants, and eating the skin boosts nutritional value since most nutrients are concentrated there.
How to Select the Best Squash
Choosing quality summer squash and zucchini enhances both flavor and nutrition. Here are essential selection tips:
- Opt for vegetables that feel firm and heavy for their size, with smooth, glossy skin.
- Inspect for blemishes or soft spots—these can lead to spoilage and decrease shelf life.
- Choose smaller, younger squash for sweeter flavor and tender texture. Overly large squash may become seedy and watery.
Proper Storage Tips
To maintain the freshest quality, use these storage guidelines:
- Ideal storage temperature: 41–50°F (too cool for counter, too warm for fridge; but the crisper drawer is best).
- Place squash in a perforated plastic bag in the refrigerator’s veggie drawer to retain moisture.
- Do not wash or cut squash until ready to use, as moisture accelerates spoilage.
- When stored properly, summer squash and zucchini will last at least 3–5 days.
Culinary Uses and Cooking Methods
Both summer squash and zucchini are versatile ingredients that can be used interchangeably in most recipes. Here are popular ways to prepare these vegetables:
- Raw: Chop, slice, or grate for salads, slaws, sandwiches, or veggie trays.
- Baked: Add to casseroles, gratins, lasagna, or savory pies.
- Grilled or Roasted: Brush with olive oil; season and grill or roast for smoky flavor.
- Sautéed: Mix with garlic, onions, and other summer produce like tomatoes and peppers.
- Stuffed: Hollow out large squash or zucchini; fill with grains, cheese, and herbs; bake until tender.
- Stir-fried: Slice into ribbons or coins for use in Asian stir-fries.
- Baked Goods: Grate into quick breads, muffins, cakes, or pancakes for moisture and nutrition.
- Pasta Substitutes: Spiralize into “zoodles” as gluten-free pasta alternatives.
