Miso soup is a gentle, savory introduction to Japanese cuisine for your little one, offering a unique umami flavor that many babies enjoy. Made from fermented soybeans, it provides probiotics that support a healthy gut microbiome, which is important for digestion and immune function in infants.1 It's also a good source of plant-based protein and essential minerals to support your baby's growth.
Miso soup can be introduced around 6 months when starting solids, as long as it's prepared safely without added salt or large pieces. Wait until your baby is comfortable with single-ingredient purees first.
Store miso paste in an airtight container in the refrigerator for up to a year. Once made into soup, it keeps in the fridge for 2-3 days; freeze baby portions in ice cube trays for up to 2 months.
6 to 9 monthsFor beginners, serve miso as a thin, strained broth without any solid ingredients. Mix 1 teaspoon of miso paste with 1 cup of warm water, strain through a fine sieve, and offer a few spoonfuls. Ensure it's cooled to room temperature.
9 to 12 monthsYou can add soft, cooked vegetables that have been mashed or finely chopped, like carrot or spinach. Keep the broth thin but with some texture. Tofu can be included if mashed to a paste consistency.
12 months +Toddlers can enjoy miso soup with small, soft pieces of tofu, well-cooked vegetables, and even a bit of cooked noodle or rice. The broth can be slightly thicker, but avoid large chunks that could pose choking hazards.
Introduce on its own and watch closely for any signs of a reaction.
Miso is rich in probiotics from fermentation, which help maintain a balanced gut flora and may reduce digestive issues like constipation in babies.1 It contains vitamin K for blood clotting and bone health,2 B vitamins for energy metabolism,3 and minerals like copper and manganese that support enzyme function and development.4
Pair miso soup with vitamin C-rich foods like sweet potato or bell pepper to enhance iron absorption from other ingredients,5 making it a more nutritious meal for your baby.
Traditional miso can be high in sodium, but you can make a baby-friendly version by using low-sodium miso paste and diluting it with more water. Avoid adding any extra salt or soy sauce. Start with small amounts (1-2 teaspoons) to monitor tolerance.
It's best to avoid instant packets as they often contain high sodium, preservatives, or MSG. Instead, make homemade soup with plain miso paste, water, and soft-cooked vegetables you've already introduced to your baby.
The umami flavor can be strong for some babies. Try mixing a small amount of miso broth into familiar foods like rice cereal or vegetable puree to gradually introduce the taste. It may take several attempts before they accept it.
