Can Babies Eat Sea Kale? Yes, From 6 Months

Sea kale is a mild coastal brassica, usually eaten as its pale blanched stems, and babies can have it from around 6 months. It is not a common allergen. Cook it until soft and finely chop it, since firm pieces are a choking risk.

Sea kale is a handsome coastal cabbage relative that old kitchen gardeners prized, growing it under pots to blanch the young stems pale and tender. Those forced stems are the classic part to eat, with a mild, sweet, nutty flavor a bit like a cross between asparagus and cabbage. The leaves are edible too when young. From around 6 months, cooked until soft and finely chopped, sea kale is a gentle brassica for a baby. It is not a common allergen. The thing to manage is firmness: the stems need cooking right through until soft and cutting small before they reach a baby.

Is sea kale safe? Choking & prep

Sea kale is not a common allergen, so texture is the priority. The stems are firm when raw or undercooked, which is a choking risk, so cook them right through until soft and cut them into small pieces or mash them for a baby¹. Cook young leaves soft and finely chop them as well. Wash everything thoroughly, especially anything foraged from the coast, and be sure of your source, since sea kale is a protected wild plant in some places and cultivated sea kale is the reliable option. Add no salt. Introduce it on its own for a couple of days if you want to watch how your baby handles it, then mix it in.

Nutrition

Sea kale offers the brassica strengths of vitamin C, vitamin K, and folate, plus fiber, in a mild and slightly sweet package. Like other cabbage-family vegetables it brings the beneficial plant compounds that make this group worth eating often. The vitamin C helps a baby absorb iron from the same meal, so it pairs well with iron-rich foods. Because the tender blanched stems are so mild, sea kale is an easy way to keep offering the cabbage family without the strong flavors that can put some babies off, which helps build familiarity with those tastes over time.

Goes well with

Mashed potato · Soft-cooked rice or pasta · Soft-scrambled egg · Shredded chicken or flaked fish · A little olive oil or unsalted butter

Storage & freezing

Keep sea kale wrapped in the fridge and use it within a few days, as the tender stems do not last long. Wash it just before cooking. Once cooked, cover leftovers and use within a day, or freeze small portions of cooked, chopped sea kale and thaw in the fridge before serving.
