How to serve pistachios by age

6 months+

Finely ground pistachios or thinned pistachio butter

Grind plain, unsalted, shelled pistachios to a fine powder and stir it into porridge or puréed fruit or vegetables. Or thin smooth pistachio butter with a little water, breast milk or formula until runny. Toast strips are fine once wheat has been introduced on its own.

Size: Stirred into a smooth food, or spread very thinly on soft toast strips about the size of an adult finger, roughly 6–8 cm long and 2 cm wide (2½–3 × ¾ in).
Check before serving: Rub a pinch of ground pistachio between your fingers: it should feel like flour, with no gritty bits. Thinned butter should drip easily off a spoon.

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 pistachios

1
Choose plain, shelled pistachios, or smooth pistachio butter, with no added salt or sugar. Many pistachios are sold salted, so check the label.
2
Blitz the pistachios in a clean, dry blender or spice grinder in short bursts until they're a fine powder. Sieve out any bits that won't grind.
3
Stir about ½ teaspoon of ground pistachios, or pistachio butter thinned with water, breast milk or formula, into a food your baby already eats.
4
First time? Pick a day your baby is well, at home, when you can watch them for a couple of hours afterward.

How much to offer

For the very first taste, offer a small amount: about ½ teaspoon stirred into food. If there's no reaction, offer more next time. Your baby decides how much to eat. After that, the goal is to keep pistachios in your baby's diet regularly, not to finish a portion.

Common mistakes

Offering whole or chopped pistachios

Pieces of nut are a choking hazard for young children. Grind pistachios finely, or use smooth pistachio butter, thinned or spread thinly.

Using salted pistachios

Babies shouldn't have added salt. Buy unsalted, shelled pistachios and grind them yourself.

Starting with a mixed nut snack or dessert

Offer pistachio on its own first, so you know what caused any reaction. Nut mixes and desserts can also contain other nuts, salt, sugar or honey.

Offering it once and stopping

Once pistachio is in your baby's diet, keep offering it regularly. Use the tracker below to see when you last offered it.

Where US and UK guidance differ on pistachios

United States(AAP and CDC)Your setting

The AAP advises keeping nuts from children until about 4 years, depending on the child, and the CDC lists whole or chopped nuts and chunks or spoonfuls of nut butter as choking hazards. Finely ground pistachios, or smooth pistachio butter thinned or spread thinly, are fine from around 6 months.

United Kingdom(NHS)Your setting

The NHS says no whole nuts for children under 5. Crushed or ground nuts added to food, and nut butter spread on a food such as toast (never on its own; we suggest spreading it thinly), are fine from around 6 months. If your baby has eczema or a diagnosed food allergy, or there's a family history of food allergies, eczema, asthma or hay fever, talk to your GP or health visitor before introducing any nut.

Questions parents ask

Can pistachios be a choking hazard for babies?

Whole and chopped pistachios are a choking hazard. The AAP advises keeping nuts from children until about 4 years, depending on the child, and the NHS says no whole nuts under 5. Serve pistachios finely ground, blended completely smooth, or as smooth butter thinned or spread very thinly. Never offer spoonfuls or chunks of thick pistachio butter, and keep bowls of pistachios out of reach.

Can babies be allergic to pistachios?

Pistachios are a tree nut, one of the most common food allergens. Current guidance is to introduce common allergens, including nut products, from around 6 months once your baby has started solids, then keep offering them regularly. Start with a small amount when your baby is well and watch for signs of a reaction. Pistachio and cashew are closely related: in one allergy clinic study, everyone allergic to pistachio was also allergic to cashew. Tree nut allergy usually lasts for life: fewer than 1 in 10 people outgrow it. Between 25% and 40% of people with a peanut allergy also react to at least one tree nut.

Are pistachios healthy for babies?

A source of protein, fiber, vitamin B6, potassium and copper. Pistachios have some iron (about 3.9 mg per 100 g), but a teaspoon of ground pistachios gives well under 1 mg.

When can my child eat whole pistachios?

Not until at least 4 years in the US (the AAP says 4 years or older, depending on the child) and 5 years in the UK. Until then, keep them finely ground, blended smooth or as a thinned butter.

My baby already eats cashews. Are pistachios fine too?

Still introduce pistachios on their own, as a new food. Pistachio and cashew are closely related, so if your baby has ever reacted to cashew, ask your pediatrician or allergist before trying pistachios.

If my baby is fine with pistachios, are other nuts fine too?

Not necessarily. Each tree nut is a different food. Introduce them one at a time, in a safe form, so you can spot any reaction.

My baby is allergic to peanuts. Can they have pistachios?

Ask your allergist first. Peanuts are legumes, not tree nuts, but 25% to 40% of people with a peanut allergy also react to at least one tree nut.

If your baby refuses pistachios

Many babies need 10 or more tries before they accept a new food. Keep offering it alongside foods they already like.
Try another form: stirred into porridge, spread thinly on toast, or baked into pancakes.
Eat some yourself at the same meal. Babies copy what they see.
If your baby keeps refusing pistachios and you're relying on them as an early allergen, mention it to your pediatrician.

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

Buying and storing pistachios

Store pistachios and pistachio butter as the label directs, and stir any separated oil back into the butter so it's smooth.
Porridge or purée with pistachio stirred in keeps for 3 to 4 days in a covered container in the fridge.
Pancakes and muffins made with ground pistachios can be frozen for 2 to 3 months. Reheat 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:

Your baby has severe eczema, a peanut allergy or another food allergy. Talk to your pediatrician or allergist about how to introduce tree nuts, not about putting them off.
Your baby has reacted to cashew. Ask your allergist before offering pistachios, because the two allergies very often go together.
Your baby has had any reaction to pistachios or another tree nut, even a mild one. Stop offering it until you've talked to your pediatrician.
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.
