Eight Ways to Cook and Serve Summer Squash

Stuffed zucchini bakedSummer or tender squash can be sautéed, steamed, boiled, baked,  grilled, microwaved, or eaten raw. Use raw tender squash as an addition to crudités trays and salads

The tender summer squashes–zucchini, Costata Romanesca, round and globe, scallop or pattypan, yellow crookneck, and yellow straightneck, and Zephyr–mature during the summer and can be claimed as baby or mini-squashes in late spring.

Tender summer squashes are ready for picking as early as 7 days after flowering and are best eaten raw or cooked before they reach maturity while their skins and seeds remain soft and edible.

Tender squashes are soft-skinned and slice easily. They are mild-flavored–even buttery, nutty, or cucumbery tasting. They are high in water content which means that they are perfect for eating raw or cooking quickly–but won’t store long.

(By contrast, winter or hard-skinned squashes–which get their start in the spring and summer along with summer squashes–can not be eaten before they mature. Their skins must grow hard and their flesh starchy before they are ready for cooking. (This, in turn, allows them to be stored and used into the winter–thus the name “winter squash.”)

Types of Summer Squashes

  • Zucchini is a smooth-skinned, cylindrical squash measuring 2½ to 8 inches (6.4-20 cm) long. The skin color is yellow but a concentration of green pigments gives it an appearance of pale and dark green stripes. Sometimes called the “classic zucchini”, this vegetable resembles a large cucumber. It has a cream-colored watery flesh that can be bland tasting. The name “zucchini” came into general use in California in the 1920s and 1930s. Before that the Italians referred to the same vegetable as “cocozelle” and the French and British called this vegetable “courgette.” A more flavorful variety of zucchini is the golden zucchini which is the same size and shape as the classic green zucchini but with a glossy bright yellow skin. Golden zucchini has a light, buttery flavor.
  • Squash Costata Romanesca

    Costata Romanesca–sometimes called ribbed Roman zucchini and also called cocozelle–is an elongated slightly bell-shaped, pale green squash with raised ribs that measures 10 to 15 inches (25-38 cm) long and about 5 inches (13 cm) thick in diameter. The green skin is marked by light greenish-yellow stripes that run the length of the vegetable. Costata Romanesca is juicy and sweet flavored but does not keep long. Costata Romanesca is sometimes called marrow squash or vegetable marrow.

  • Yellow crookneck and yellow straightneck squashes are bright yellow-skinned squashes that measure from 8 to 10 inches (20-25 cm) long with slightly swollen or bulbous bases that taper to slender necks. Their skins are slightly pebbly or warty and their flesh is off white. The crookneck variety has a swan-like neck. Both varieties have mild sweet to bland zucchini-like flavor and crunchy texture.
  • Zephyr is a cross between the Delicata and yellow Acorn squashes with a slightly crooked neck about 5 to 8 inches (13-20 cm) long. This squash is bi-colored–pale green at the stem end and bright yellow most of the length. Zephyr has a somewhat sweet flavor.
  • Scallop or pattypan–also called custard squash or cymling–is a saucer- or mushroom cap-shaped squash with a pale green skin bordering on white. It can also be golden yellow and white. This squash is best eaten when 3 to 4 inches (7.5-10 cm) in diameter. The flesh of the pattypan has less moisture than zucchini and becomes hard as it ripens, much like winter squash. This squash is smooth fleshed but rather bland flavored. Cymling is an American Indian word for a white scalloped squash.
  • Scallopini is similar in shape to pattypan with speckled green skin similar to a zucchini.
  • Sunburst is a hybrid small- to medium-sized scalloped squash that looks something like a plump pattypan. It has bright yellow skin and off-white meat with a delicate, mildly sweet flavor.
  • Round zucchini

    Round zucchini or globe squash is about 5 inches (13 cm) in diameter with a skin of varying shades of green. This is a seedless and smooth textured squash that is nearly seedless. It is a juicy and flavorful squash with green-tinted flesh.

  • Tatume is an oval, egg-shaped, pale green squash about 5 inches (13 cm). This seedless, smooth-fleshed squash weighs about 1 pound (.45 kg) and has a slightly sweet flavor.
  • Middle Eastern-type zucchini–also called Lebanese, Egyptian, Cousa, Kuta, and Magda–is a usually stocky, pale-green tapering squash about 5 inches (13 cm) long. It has a smooth, thick, dark green skin with solid, crisp, moist and flavorful flesh.
  • Baby squash or mini-squash is any squash harvested when very young.

How to Choose Summer Squash

  • Select summer squashes that are still tender. Summer squashes that reach maturity will be drier with thicker skins. Choose firm, undamaged squashes with glossy skins free of cracks and blemishes. Select smaller to medium-sized specimens. Overly large squashes tend to be fibrous and bitter, and very small squashes can lack flavor.
  • Zucchini and crooknecks that are 5 to 10 inches (13-25 cm) long are good for slicing into rounds; those 3 to 5 inches (7.5-13 cm) long are best for use whole. Yellow varieties are best when 4 to 7 inches (10-18 cm) long.
  • Scallop or pattypan varieties are best when 3 to 5 inches (7.5-13 cm) in diameter.

How to Store Summer Squash

  • Tender squashes placed in a perforated plastic bag in the refrigerator will keep for about 1 week. Handle summer squash with care because it is easily damaged.
  • Summer squash can be frozen but the flesh will be softer when served. Cut the squash into slices and blanch for 2 minutes before freezing. Frozen squash will keep for 3 to 4 months.

How to Prep Summer Squash

  • Before eating or cooking, wash and cut off both ends of the squash. Unless the skin is bitter, you do not have to peel tender squash.
  • Squash can be used whole, grated, halved, or cut into cubes, strips or slices. Trim the ends and cut into chunks or slice before cooking.
  • You can “drain” squash with high water content by cutting it into slices and arranging it in a shallow dish. Then sprinkle the slices uniformly with coarse salt and let drain for 20 to 30 minutes. Use a strainer and rinse the slices under cold running water, pat them dry, and proceed with your recipe.

Get to Know Summer Squash

  • Tender squashes are warm-season annuals. They are weak stemmed plants that usually grow as a bush. Tender squash has large, lobed cucumber-like leaves that are covered in small prickles.
  • The fruits of tender squashes are almost always eaten in the immature state before the skin hardens. Summer squashes are for warm weather harvest and are eaten when immature.
  • Squashes are in the same family as the melon and cucumber. Cultivated squashes are descended from wild squashes which originated in the American tropics–between Mexico and Guatemala.
  • Squash has been cultivated for more than 10,000 years. The ancient Aztec, Incan, and Mayan peoples considered squash one of the “three sisters” that should be grown together–corn for its stalk, beans that climb the corn, and squash to creep along the surrounding ground to keep the weeds away.
  • The name squash is an abbreviation of the Native American word askutasquash meaning eaten raw or uncooked.

The botanical name for tender squash is Cucurbita pepo.

  1. The summer squash you are describing is named ‘Zephyr.’ About 4 to 6 inches long at harvest time ‘Zephyr’ is a straigthneck squash that is yellow at the stem end. light green at the blossom end, with faint white stripes running the length. ‘Zephyr’ is a firm, nutty flavored squash perfect for quick cooking. ‘Zephyr’ is a hybrid, has an open form or habit, and is ready for havest about 54 days after sowing. If you are in a warm winter region, you have plenty of time to bring ‘Zephyr’ to harvest.

  2. Far from being an outdated term, what you call “zucchini” are still called “courgettes” in the UK and Europe. Even the Italian seed companies call them that.

    I’ve seen conflicting reports of whether the skin of uchiki kuri squashes is edible: some recipes claim it is, some expect one to peel them. Since I’ve got a number of baby ones, it would help to know if those are edible at that stage.

    • The younger the plant the more tender the skin; I would expect your baby kuri squashes to be wholly edible.The skin of a maturing kuri squash does harden with time, but even so the skin can be eaten at maturity–commonly after baking. Some recommend not eating the skin of winter squashes because of the length of time they are in the field and possible exposure to pesticides, but this would not be a concern for organically grown squashes.

  3. Hey Steve, I have recently moved from the US to Russia and they have here what I know as regular green zucchini and also what I now believe to be the Magda squash. It is a very pale green color, and they call it ‘squash’. My question is this, I love to bake and make zucchini breads, etc. Do you know if the Magda would be ok to bake with like I do regularly with the green zucchini? Thank you!
