Yes, babies can enjoy leek from around 6 months, and it is one of the gentlest ways to introduce the onion family. Cooked low and slow, leek turns mild and quietly sweet, nothing like the sharp bite of raw onion. It is a classic French first vegetable for good reason: it purees like a dream and melts into almost anything. The only real job is washing. Soil loves to hide between those tightly packed layers, so slice first, rinse well, then cook until it is silky soft.
Prep School: how to prepare leek for baby-led weaning (BLW) and purées
🍴 Baby-led weaning
These baby-led weaning steps start at 9 months. If your baby is younger, you can still offer this food the Purées way from 6 months: mashed, or finely minced into a soft food they can manage.

Is leek safe? Choking & prep
Leek is not a common choking or allergy risk,12 but the dark green tops stay tough and stringy, so stick to the soft white and pale green parts for babies and always cook until very soft.1

Nutrition
Leek brings a quiet but useful mix of nutrients to the plate.3 It offers vitamin K, which supports healthy blood and bones,4 along with folate, a B vitamin that helps tissues grow.5 There is also gentle fiber to keep digestion moving, plus small amounts of vitamin C and manganese. Because leek is so mild once cooked, it is an easy way to add these to purees and mashes without overpowering everything else on the spoon.
Goes well with
Potato, for a classic soft leek-and-potato mash or puree · Butternut squash or sweet potato for extra sweetness · Peas or spinach blended in for color and iron · Chicken or white fish for a fuller savory meal · A little cheese stirred through for older babies · Rice or soft pasta to build a simple risotto or bake
Storage & freezing
Store raw leek loosely wrapped in the fridge for up to a week. Cooked leek or leek puree keeps 1 to 2 days in the fridge, or freeze it in portions for about 1 to 2 months.6
