Buttercup squash is a dark green, turban-shaped winter squash with a little button on the bottom, and it hides some of the sweetest, creamiest flesh in the squash family. It is dense and dry rather than watery, which gives a rich, almost sweet-potato-like mash once cooked. From around 6 months, roasted or steamed until soft and scooped from its hard skin, buttercup makes a smooth, satisfying purée. Because the flesh is so dense, you may want to thin it a touch more than a watery squash for a young baby.

Is buttercup squash safe? Choking & prep

Buttercup is safe and gentle when cooked soft. Do not offer the hard skin, and cook the flesh until it squashes easily between your fingers². Because the flesh is dense and dry, mash it well and thin it for younger babies so it is not too thick and sticky to swallow comfortably. Scoop out the seeds and strings first. It is not a common allergen and rarely causes reactions, but introduce it like any new food and watch for about 3 days. Keep your baby seated and supervised. Rarely, a buttercup squash tastes bitter. The bitterness comes from cucurbitacin, a natural toxin that cooking does not destroy, and it has turned up in store-bought squash as well as garden-grown ones.³⁴ Before cooking, taste a tiny bit of the raw buttercup squash yourself (not your baby), spit it out, and throw the whole squash away if it is bitter.³

Nutrition

Buttercup squash is rich and nutritious, with the beta-carotene that gives its flesh that deep orange color and converts to vitamin A for eyes, skin, and immunity. Its density means it is a bit more filling and calorie-rich than watery summer squashes, along with vitamin C, potassium, and fiber. That makes it a satisfying base for a meal, though it is still worth pairing with an iron- and protein-rich food so your baby gets the complete picture.

Goes well with

Soft-cooked red lentils · Full-fat plain yogurt · Shredded chicken or turkey · Cooked oats or rice · A pinch of cinnamon or nutmeg

Storage & freezing

Whole buttercup squash stores for a month or more in a cool, dry, dark place. Once cut, cover the raw squash, refrigerate it and use it within about 4 days. Cooked squash keeps 1 to 2 days in the fridge, or 1 to 2 months in the freezer.⁵ The dense mash freezes very well, so portion it into small containers or an ice-cube tray and thaw as needed for quick meals.
