Calabacitas
Calabacita is the Spanish word for a small, tender summer squash widely used in Mexican cooking, most often a round or oblong pale green variety (sometimes called Mexican squash or tatuma) that's related to zucchini but generally sweeter, thinner-skinned, and less watery. The name is also used loosely across Latin American markets to mean any young, tender squash, including standard zucchini. The dish called calabacitas, squash sautéed with corn, onion, tomato, and often cheese, takes its name directly from the vegetable.
Varieties
True calabacita (often the tatuma or gray Mexican squash variety) is rounder, paler green, and slightly sweeter than standard dark-green zucchini, but in most U.S. grocery stores the two are used interchangeably and often labeled simply as "Mexican squash."
Buying tips
Choose small to medium squash, no longer than about 6 inches, with smooth, glossy, unblemished skin. Smaller squash have fewer seeds and less watery flesh; larger, dull-skinned ones tend to be tougher and more bitter.
Substitutes
Zucchini — 1:1
The closest everyday substitute; use slightly less cooking liquid since zucchini releases more water as it cooks.
Yellow crookneck or straightneck squash — 1:1
Similar texture and mild flavor, though slightly firmer flesh that holds up a bit longer in a skillet.
Pattypan squash, diced — 1:1
Denser and slightly sweeter; dice small since the flesh is firmer than true calabacita.
Chayote, peeled and diced — 0.75:1
Crisper and less sweet, so use a bit less by volume and expect a longer cook time to soften.
Storage
Keep unwashed calabacitas in a perforated plastic bag in the refrigerator crisper drawer. They're more delicate than zucchini and are best used within 4 to 5 days before the skin starts to wrinkle.
How to use
Diced and sautéed with onion, garlic, corn kernels, and tomato for the classic calabacitas dish, often finished with queso fresco or shredded Monterey Jack. Also good grilled in thick slices, stuffed and baked, or simmered into soups and rice.
What it pairs with
Pairs naturally with corn, poblano or Anaheim chiles, tomato, epazote, cilantro, and queso fresco or crema.
Nutrition
Low in calories and mostly water by weight, calabacitas provide vitamin C, potassium, and small amounts of folate, similar to zucchini.
FAQ
Is calabacita the same as zucchini?
They're closely related but not identical. Calabacita usually refers to a paler, rounder Mexican squash variety that's sweeter and holds up slightly better in a skillet, though zucchini works as a near-identical substitute.
Do you need to peel calabacitas?
No. The skin is thin and edible, just like zucchini skin, and peeling it removes texture and nutrients without any real benefit.
Why do my calabacitas turn watery when cooked?
Squash releases water as it heats. Cook it over medium-high heat in a single layer rather than crowding the pan, and add tomatoes or other juicy ingredients only after the squash has started to soften.
Can calabacitas be frozen?
Yes, but only after blanching for about 2 minutes and cooling in ice water; raw frozen squash turns mushy once thawed. Blanched and frozen calabacitas keep for about 8 months and are best used in cooked dishes rather than raw.
