Prep warning
Miso is very high in salt, which a baby's kidneys handle poorly. Use only a tiny amount diluted into a larger dish, keep the rest of the day's foods low in salt, and treat miso as an occasional seasoning rather than a regular part of meals.
How to serve by age
6-9 months
Miso is a fermented soybean paste that is very salty, so it works only as a tiny seasoning, not a food on its own. Whisk a small dab into a larger pot of vegetable or grain mash to add savory depth, then serve a baby-size portion. Because it is made from soy, offer it on its own first, on a day when you can watch for any reaction.
No cutting needed. Dissolve a tiny amount into a larger dish so the salt is spread very thin.
9-12 months
Keep miso as an occasional background flavor in cooked dishes. A small amount stirred into a broth, a vegetable stew, or a grain bowl is plenty. Balance it with low-salt or salt-free foods across the day, since its sodium adds up quickly.
No cutting needed. Stir a small amount through a cooked dish.
12-18 months
Miso can flavor family soups, marinades, and dressings, used sparingly. A small spoonful seasons a whole pot, so a toddler portion carries only a little. Keep total salt low across meals and pair miso dishes with plain, unsalted sides.
No cutting needed. Use sparingly as a seasoning in cooked dishes.
