How to serve fennel by age

6 months+

Very soft-cooked strips, core removed, or mashed into food

Cut out the hard core, peel any tough outer layer, and cut the bulb into finger-sized strips. Simmer, steam or braise until very soft. Or mash or blend cooked fennel into potato, lentils or soup. Never offer raw fennel.

Size: Strips about the size of an adult finger, roughly 6–8 cm long and 2 cm wide (2½–3 × ¾ in), or mashed into soft foods.
Check before serving: Squash a strip between your thumb and finger. It should flatten easily, with no tough strings left. If you feel strings or have to press hard, cook it longer.

US and UK advice differ here. The AAP suggests mashed food or soft pieces no larger than ½ inch; the NHS suggests soft finger-sized pieces your baby can hold in their fist. Both agree the food must squash easily.

Always have your child sit upright in a high chair or at the table, and stay with them the whole time they eat. Keep to the size and texture for their stage. Every baby develops on their own timeline.

How to prepare fennel

1
Cut off the stalks and fronds, then rinse the bulb under running water, rubbing off any dirt at the base.
2
Trim the root end, peel off any tough or bruised outer layer, cut the bulb in half and cut out the hard core.
3
Cut it into finger-sized strips (6 months) or slice thinly and chop finely (9 months+). Simmer, steam or braise for about 15 to 25 minutes, until very soft. Don't add salt.
4
Do the squash test and check for strings, then let it cool before serving.

How much to offer

Start with one or two strips or a spoonful mixed into a food your baby already knows. Your baby decides how much to eat: stop when they turn away or close their mouth. Lots of licking, squashing and dropping is normal at first.

Common mistakes

Offering raw fennel

Raw fennel is hard, crunchy and fibrous, and the CDC lists pieces of hard raw vegetables as a choking hazard. For babies, always cook it until it squashes between your fingers.

Leaving the core in

The core at the base of the bulb stays hard even after cooking. Cut it out before you slice the fennel.

Cooking it just tender

Lightly cooked fennel stays firm and stringy. Cook it longer, until it passes the squash test.

Seasoning the family pot first

Take your baby's portion out before adding salt, stock cubes or gravy to soups and stews.

Where US and UK guidance differ on fennel

United States(AAP and CDC)Your setting

Keep serving fennel cooked soft. The AAP says that apart from mashed banana, most fruits and vegetables should be cooked until soft for babies, and lists raw vegetables among foods to avoid under 1. The CDC lists hard raw vegetables as a choking hazard for young children, and the AAP advises holding back raw vegetables until about 4 years, depending on the child.

United Kingdom(NHS)Your setting

Cook fennel until soft in the first year: the NHS says to avoid hard foods like raw carrot for babies. From 12 months, the NHS snack list includes cooked or raw vegetables. For very young children, the NHS suggests grating, mashing, steaming or simmering firm vegetables. If you offer raw fennel to a toddler, grate it finely, and stay with them.

Questions parents ask

Can fennel be a choking hazard for babies?

Raw fennel is hard, crunchy and fibrous: the CDC lists pieces of hard raw vegetables as a choking hazard for young children, and the NHS says to avoid firm foods. Cut out the hard core, cook fennel until very soft, and serve it in strips that squash easily or finely chopped into cooked dishes. For toddlers, US and UK advice differs on raw vegetables: see the guidance note below. Stay with your child during meals.

Can babies be allergic to fennel?

Fennel is not a common allergen.

Is fennel healthy for babies?

Raw fennel bulb has about 3 g of fiber and 12 mg of vitamin C per 100 g, plus some potassium and vitamin K. FoodData Central has no cooked entry, and cooking can lower vitamin C. Fennel isn't a major source of iron: about 0.7 mg per 100 g, compared with the 11 mg a day babies 7–12 months need.

Can babies eat fennel?

Yes, from around 6 months, with the core cut out and cooked until very soft. Soft strips, or fennel mashed with potato or blended into soup, are good first forms.

When can toddlers eat raw fennel?

Not under 1 year. The AAP advises holding back raw vegetables until about 4 years, depending on the child. The NHS lists raw vegetables among snacks from 12 months, but suggests grating firm vegetables for very young children, so grate raw fennel finely if you offer it. See the US vs. UK note.

Can babies eat roasted fennel?

Yes, if it's soft all the way through. Roasted fennel can stay firm in the middle and crisp at the edges, so trim off browned edges and do the squash test.

Can fennel help with constipation?

Fennel has some fiber, and the NHS suggests plenty of fruit and vegetables, plus enough to drink, to help prevent constipation. If your baby is constipated, talk to your pediatrician.

If your baby refuses fennel

Many babies need 10 or more tries before they accept a new food. Keep offering it alongside foods they already like.
Mix a little soft-cooked fennel into a food your baby already enjoys, such as mashed potato or lentils.
Eat some yourself at the same meal. Babies copy what they see.
Funny faces don't mean they dislike it. They're getting used to a new taste and texture.

Never force or pressure your baby to eat. Some days they'll eat more, some days less, and that's normal.

Buying and storing fennel

Keep raw fennel in the fridge.
Cooked fennel keeps for 3 to 4 days in a covered container in the fridge. Rice dishes are the exception: cool them within 1 hour, keep them in the fridge for no more than 1 day, and reheat them only once.
Cooked fennel, or soups and mash made with it, can be frozen for 2 to 3 months. Thaw them in the fridge, use them within 24 hours of thawing, and reheat them only once, to 165°F (74°C), until steaming hot, then let them cool before serving.
Throw away any food left out at room temperature for more than 2 hours (1 hour if it's hotter than 90°F / 32°C).

When to talk to your doctor

Contact your pediatrician, GP or health visitor if:

You notice mild signs of an allergic reaction after eating, such as a few hives or a little vomiting. See signs of a reaction.
You're worried about how much your baby eats, their growth, or they refuse most solid food for weeks.

Call 911999your local emergency number (such as 112 in Europe or 000 in Australia) now if your baby has trouble breathing, wheezing, can't cough or cry, has lips, mouth, tongue or throat that suddenly swell, or becomes pale, bluish, floppy or unresponsive. Also call if hives come with repeated vomiting.
