Kidney beans for babies

Kidney beans are an excellent iron food with one real caveat: raw and undercooked kidney beans contain a toxin, so tinned or thoroughly boiled is the only way to serve them.

When can babies have kidney beans?

From around 6 months, tinned or fully boiled, then mashed or squashed. Never serve kidney beans that have only been slow-cooked from dry without a hard boil first.

How do you serve kidney beans to a baby?

The shape is what makes a food safe, and it changes as your baby’s grip and chewing change. Find your baby’s age band.

6–8 months

Mashed into a thick paste and spread on toast, or mixed with mashed sweet potato or rice so it holds together on a spoon.
9–11 months

Squashed whole beans for pincer practice, or in a mild chilli with soft rice.
12–18 months

Whole soft beans, bean burgers, mild chilli, or in a soup.
18–24 months

Family portions, low salt.

Prep tip

If cooking from dry, soak for at least five hours, discard the water, then boil hard for at least 10 minutes before simmering. A slow cooker alone does not reach a high enough temperature to destroy the lectin.

Storage

Cooked beans keep four days refrigerated and freeze well. Rinse tinned beans thoroughly to remove sodium.

Is kidney beans a choking hazard for babies?

Choking risk Moderate

Whole kidney beans are large and firm-skinned. Squash them flat or mash them for the first year. Cooked properly they are soft enough to compress easily.

Whatever you serve, stay within arm’s reach, keep your baby upright in a supportive seat, and never let them eat in a moving car, buggy or carrier. Gagging is loud and normal. Choking is silent.

Is kidney beans a common allergen?

Common allergen No

Kidney beans is not one of the nine most common food allergens. Any food can trigger a reaction, though, so offer it on its own the first time and watch for hives, vomiting, swelling or a change in breathing over the next two hours.

Is kidney beans healthy for babies?

Kidney beans carry more iron than most legumes and a large amount of fibre and folate. Paired with a vitamin C food — tomato is the classic and works nutritionally as well as culinarily — they are a strong iron contribution in a meat-free meal.

Common questions about kidney beans

Why do kidney beans need a hard boil?

Raw and undercooked kidney beans contain phytohaemagglutinin, a lectin that causes vomiting and stomach upset. A 10-minute rolling boil destroys it. Tinned kidney beans are already cooked and are perfectly safe.

Are tinned kidney beans as good as dried?

Nutritionally very close, and safer for the reason above. Rinse them thoroughly — the canning liquid carries most of the added salt.
