Flageolet beans are young haricot beans picked before they fully mature, which gives them a pale green color and a mild, buttery flavor that babies tend to like. They are a legume rather than a top-9 allergen, but introduce them on their own for a few days as you would any new food. The one thing to get right is cooking: like other beans in the kidney family, dried flageolet beans must be soaked and then boiled hard for at least 30 minutes, never served firm or undercooked. Canned flageolet beans are already cooked, so choose a no-salt-added variety, rinse them well, and warm them through. Once soft, mash or lightly smash them so the skins flatten and they are easy to gum.

Prep School: how to prepare flageolet beans for baby-led weaning (BLW) and purées

🍴 Baby-led weaning

9 monthsA firm whole bean is tricky for a new eater, so this starts as a thick mash rather than a finger food. Cook the beans until very soft, mash them, and offer the mash on a preloaded spoon or stirred into a vegetable mash your baby can scoop. Use no-salt-added canned beans rinsed well, or dried beans soaked at least 5 hours and boiled in fresh water at least 30 minutes until very soft.

12 months+Lightly smash soft whole beans so they flatten, which makes them easy to pick up and gum.

18 months+Offer soft beans flattened between your fingers, or folded into rice, soft grains, and vegetable mashes kept low in salt.

🥄 Purées

9 monthsCook the beans until very soft and mash them into a smooth puree, thinning with a little water or breast milk, or stir the mash into a vegetable puree. Never spoon them up firm or crunchy.

12 months+Lightly smash soft whole beans into the mash for a lumpier spoonful as your baby handles more texture.

18 months+Fold soft beans, lightly mashed or flattened, into rice, soft grains, and vegetable mashes, kept low in salt.

Are flageolet beans safe? Choking & prep

The main things to get right with flageolet beans are cooking and texture. If you start from dried beans, soak them for at least 5 hours, pour the water away, and boil them in fresh water for at least 30 minutes, since like other kidney-family beans they contain a natural lectin (phytohaemagglutinin) that only thorough boiling destroys and a slow cooker never gets hot enough.⁴ Canned flageolet beans are already fully cooked; choose a no-salt-added version and rinse them well. A firm whole bean can be tricky for a new eater, so cook them very soft and mash or smash them until about age 4.¹² Keep salt out, since babies under one do not need added salt, and always serve your baby seated upright and within arm's reach.

Nutrition

Flageolet beans bring plant protein, fiber, iron, and folate, which makes them a nourishing meat-free option. The iron is plant iron, so serving them alongside a vitamin C food like tomato or bell pepper helps the body absorb it. Their soft, creamy texture mashes easily, and the fiber supports digestion, so introduce them gradually alongside plenty of fluids.

Common questions

What are flageolet beans?

They are young haricot beans harvested before they fully ripen, which gives them a pale green color and a mild, buttery flavor. They are popular in French cooking and cook down soft and creamy.

Do dried flageolet beans need to be fully cooked?

Yes. Soak dried flageolet beans for at least 5 hours, pour the water away, and boil them in fresh water for at least 30 minutes, not in a slow cooker, because undercooked beans of this type contain a natural lectin that only a full boil destroys.⁴ Canned beans are already cooked, so just rinse and warm them.

Are flageolet beans a choking hazard?

A firm whole bean can be, so cook them very soft and mash or smash them until about age 4.¹² Well-cooked, mashed beans are smooth and easy to manage.

Are flageolet beans a common allergen?

Flageolet beans are not one of the top-9 allergens. Peanut and soy are the legumes on that list; flageolets are not. Even so, offer them on their own for a few days as you would any new food.

Canned or dried flageolet beans for babies?

Both work. Choose no-salt-added canned beans and rinse them well, or soak dried beans for at least 5 hours, pour the water away, and boil them in fresh water for at least 30 minutes until fully tender.⁴ Dried beans must always be cooked thoroughly, never served firm.
