Choking risk
Whole pistachios are a high choking risk - hard, and just the size and shape to block a small airway. The CDC lists whole nuts as a choking hazard, and whole or chopped nuts should wait until around age 4.
Until then, serve pistachio as thinned pistachio butter or finely ground pistachio. And mind the shells: half-shells are exactly cup-shaped for a small mouth, so shell over a separate bowl and keep it out of reach. See how to serve for age-by-age prep.
Allergens
Pistachio is a tree nut - one of the nine major allergens - and there's no reason to delay it: waiting doesn't prevent allergies, and allergens can start alongside other solids from around 6 months.[3]
If your baby has severe eczema or an existing food allergy, check with your pediatrician before starting allergens. Start with about ¼ teaspoon of thinned pistachio butter mixed into a familiar food, earlier in the day, not near bedtime. Wait 10 minutes, and if all looks well, carry on with the meal.
Watch for a reaction over the next couple of hours. Build up gradually from there, and keep tree nuts in the diet a few times a week.[2]
If baby refuses
Thinned pistachio butter is usually well liked for its mild, sweet flavor. If baby turns away, stir a little into a familiar food, then build up. Don't skip it over refusal.
How to serve
6+ months old
Thinned smooth pistachio butter or ground pistachio
About 1/4 teaspoon to start
Thin smooth pistachio butter with warm water or baby's usual milk into a loose paste, then stir it into oatmeal, yogurt, or a fruit mash. Finely ground pistachio blends into soft foods too. Never whole or chopped nuts, and never pistachio butter thick from the jar.
The first time
Offer pistachio earlier in the day, not near bedtime. Dab a little thinned pistachio butter on your clean fingertip or the tip of a spoon and let baby taste it - about ¼ teaspoon in total is plenty. Wait 10 minutes, and if all looks well, carry on with the meal. Watch for a reaction over the next couple of hours. Build up gradually from there, and keep tree nuts in the diet a few times a week.
How to prepare
No cooking needed. Start from plain, unsalted pistachios - shell them, and grind to a fine powder for stirring into food, or keep grinding until they turn to butter. Or mix about 1 teaspoon of smooth pistachio butter with 2 to 3 teaspoons of warm liquid until loose and pourable.
12+ months old
Thinly spread pistachio butter or ground pistachio
A thin layer, or a spoonful stirred in
Spread smooth pistachio butter thinly on toast or soft strips, stir it into oatmeal or yogurt, or fold finely ground pistachio into pancakes or muffins. Offer water alongside to help wash down sticky bites. Never pistachio butter thick from the jar, and never whole or chopped nuts - whole and chopped pistachios wait until around age 4, when chewing can handle them.
How to prepare
No cooking needed. Spread the butter in a thin layer that soaks slightly into the toast, or stir ground pistachio into batter before baking.
