When can babies have kidney beans?
Can babies have kidney beans?
Babies can have kidney beans from about 6 months, as soon as they are ready for solids. Kidney beans must be fully cooked, because raw or undercooked kidney beans contain a natural toxin, and they should be mashed or flattened for babies. Canned kidney beans are already cooked and are an easy option once rinsed.
How to serve kidney beans by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Blend fully cooked kidney beans into a smooth puree with a little olive oil, water, breast milk or formula, pressing it through a sieve or removing loose skins if your baby gags on them. Offer it on a spoon, alone or stirred into sweet potato or rice puree.
7–8 months
Mash cooked kidney beans with a fork so they keep some soft lumps, and stir them into rice or sweet potato. You can also spread a smooth kidney bean paste thinly on soft toast strips, or offer soft bean patties that squash easily between your fingers.
9–12 months
Flatten each soft cooked kidney bean between your fingers before serving so baby can pick it up with the pincer grasp. Mashed beans also work well in patties, quesadillas with soft tortillas, or mixed into pasta sauce.
12 months +
Serve soft whole cooked kidney beans in chili, stews, soups and rice dishes, and smash them if your toddler is still learning to chew. Cook family chili with little or no added salt and keep spice mild.
Why it’s good
Kidney beans give babies plant protein, iron, zinc, folate, potassium and plenty of fiber. Iron is especially important from 6 months, when a baby's stores start to run low. Serving kidney beans with vitamin C foods like tomato, peppers or broccoli helps the body absorb more of their iron.
Safety notes
- Never serve raw or undercooked kidney beans. They contain a natural toxin called lectin (phytohaemagglutinin) that can cause severe vomiting and diarrhea. Soak dried beans, discard the water, and boil hard in fresh water until completely soft.
- Do not cook dried kidney beans only in a slow cooker. Low temperatures may not destroy the toxin, so boil the soaked beans first, or use canned beans.
- Whole kidney beans are a choking risk for young babies because they are firm-skinned and round. Mash or flatten them until your child chews well.
- Canned kidney beans can be high in salt. Choose no-salt-added cans, or drain and rinse beans well to lower the sodium.
- Seat baby upright and stay within arm's reach while they eat.
A low-allergy food, still worth watching
Kidney beans are not one of the Top 9 allergens and reactions are uncommon, but legume allergies do occur. Babies with a peanut allergy are not automatically allergic to beans, but ask your pediatrician if you are unsure, and watch for hives, swelling or vomiting the first few times.

Are kidney beans a choking hazard for babies?
Kidney beans are a high choking risk for babies when served whole, because they are round with a firm skin. Mash kidney beans for young babies and flatten each bean for older babies until your child chews well.
Are kidney beans a common allergen?
No, kidney beans are not one of the Top 9 common food allergens. Bean allergy is uncommon but possible, so watch for hives, swelling or vomiting when you first serve kidney beans.
How do I serve kidney beans to a 6 month old?
To serve kidney beans to a 6 month old, blend fully cooked beans into a smooth puree with a little water, breast milk or formula. Offer it on a spoon, alone or stirred into grains or vegetable puree. Thin spreads on soft toast strips can follow at 7–8 months.
Can babies have canned kidney beans?
Yes, babies can have canned kidney beans, which are already fully cooked and safe. Choose no-salt-added canned kidney beans when you can, and drain and rinse them well to remove extra sodium.
Are undercooked kidney beans dangerous?
Yes, raw or undercooked kidney beans can make anyone sick, including babies, because they contain a natural toxin. Soak dried kidney beans, discard the soaking water, and boil them in fresh water until completely soft, which destroys the toxin.
Do kidney beans need to be soaked before cooking?
Dried kidney beans should be soaked for several hours or overnight before cooking. Soaking shortens cooking time and helps the beans soften evenly, and you should then boil them hard in fresh water rather than slow-cooking from raw.
Do kidney beans cause gas or constipation in babies?
Kidney beans are high in fiber, which usually helps prevent constipation, though some babies get extra gas at first. Start with small amounts, offer sips of water with meals, and increase slowly as your baby gets used to beans.
Should I remove the skins from kidney beans for my baby?
Removing kidney bean skins is optional but can help a young baby who gags on them. Blending or mashing kidney beans thoroughly usually breaks the skins down enough, and older babies can manage the skins on flattened beans.
The takeaway
- Babies can have kidney beans from about 6 months, as soon as they are ready for solids.
- Blend fully cooked kidney beans into a smooth puree with a little olive oil, water, breast milk or formula, pressing it through a sieve or removing loose skins if your baby gags on them.
