This is summer squash—either yellow crookneck or green zucchini—that has been cooked from frozen with a small amount of added fat. The texture is tender and slightly soft, with a mild, subtly sweet, and buttery flavor. Nutritionally, it's a very low-calorie, high-volume food that provides a good source of fiber and vitamin C.

↓ Full nutritionPeople love it for its incredible versatility and mild flavor, which acts as a blank canvas for herbs, spices, and other ingredients. It's a beloved staple in summer gardens and kitchens worldwide, symbolizing seasonal abundance.
The main downside is its high water content, which can lead to a soggy texture if overcooked. To counteract this, avoid overboiling; instead, sauté, roast, or grill it to evaporate moisture and concentrate flavor. Those watching sodium intake should check labels, as frozen vegetables sometimes contain added salt.
Despite its common name, summer squash is botanically a fruit, specifically a berry, as it develops from the flower's ovary and contains seeds.

Is frozen summer squash as nutritious as fresh?
Yes, often more so. Flash-freezing locks in nutrients at their peak. Frozen squash is picked ripe and processed quickly, preserving vitamins like C better than fresh squash that has traveled long distances.
Why is there added fat in the frozen product?
The fat (often oil or butter) is added during processing to help maintain texture, prevent freezer burn, and enhance flavor upon reheating. It also helps with the absorption of fat-soluble vitamins like A and K.
Can I refreeze cooked summer squash after thawing?
It's not recommended. Refreezing will significantly degrade the texture, making it very mushy and watery. It's best to cook only what you'll use from a thawed package.
