Can babies have brown lentils?
Babies can have brown lentils from about 6 months, cooked until very soft and mashed or mixed into other foods. Brown lentils are an inexpensive, iron-rich protein that many babies love. Well-cooked brown lentils are a low choking risk and are not a common allergen.
How to serve brown lentils by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Cook brown lentils until they are very soft and fall apart, then blend them with a little cooking water, breast milk or formula until smooth. Serve on a spoon or preloaded spoon, on their own or mixed into mashed sweet potato or oatmeal.
7–8 months
Mash soft-cooked lentils more roughly so they have small lumps, or stir them into thicker vegetable mashes. You can also spread lentil mash on soft toast strips or bind it with potato into soft patties that fall apart easily when pressed.
9–12 months
Offer whole, very soft cooked brown lentils on the tray for pincer practice, or mix them into rice, pasta or scrambled egg. Soft lentil patties or lentil meatballs cut into strips are easy for babies to pick up.
12 months +
Toddlers can have brown lentils in soups, stews, dal, sloppy joes, tacos and pasta sauce. Keep lentils well cooked and pair them with fruits or veggies high in vitamin C to help iron absorption.
Why it’s good
Brown lentils give babies plant iron, protein, zinc, folate and fiber, all important for growth and brain development. Pairing brown lentils with vitamin C foods like tomato, bell pepper, broccoli or strawberries helps baby absorb more of the iron. The fiber in lentils can also help keep stools soft.
Safety notes
- Cook brown lentils until they squash easily between your thumb and finger. Firm, undercooked lentils are hard to chew and can cause gagging or upset tummies.
- Never serve raw or sprouted raw lentils to babies. Raw legumes contain natural compounds that cooking breaks down.
- Rinse dry lentils and pick out any small stones or debris before cooking. A quick look on a light plate makes stones easy to spot.
- If using canned brown lentils, choose no-salt-added or low-sodium cans and rinse well to remove extra sodium.
- Cooked lentils can be grainy and coat the mouth for new eaters. Mash them with a little liquid, oil or yogurt so they are moist and smooth.
A low-allergy food, still worth watching
Brown lentils are not one of the Top 9 allergens, but legume allergies do happen, and lentil allergy is more common in some regions. Children with a peanut, pea or chickpea allergy may be more likely to react, so offer a small amount first and watch for hives, vomiting or swelling.
