Complete guide on how to prepare and serve onion paste to your baby, by age.
Last reviewed: May 2026
For infants starting solids, only introduce a very small amount of onion paste—no more than 1/2–1 teaspoon (2.5–5 ml)—mixed into other purees or mashed foods. Onion should be thoroughly cooked, blended, and cooled before serving. When served as part of a balanced meal, pair with iron-rich purees (like meat, lentils, or beans) and vitamin C-rich veggies (like bell pepper or broccoli) to help nutrient absorption. Limit seasoning and avoid adding salt. Monitor for any signs of intolerance or reaction, and do not serve raw onion at this age.

For older babies, onion paste can be increased to 1–2 teaspoons (5–10 ml) per meal as tolerated, always thoroughly cooked. Blend into dishes like mashed vegetables, lentil patties, or sauces. When building a balanced plate, serve alongside soft proteins and vitamin-rich vegetables. Still avoid raw onion, and refrain from adding salt or strong seasonings. If introducing chunkier textures, ensure all pieces are very soft and well incorporated. Observe for any reactions.

For toddlers, onion paste can be used up to 1 tablespoon (15 ml) per meal, as part of family dishes like stews, casseroles, or egg dishes. Pair with proteins, grains, and vegetables for a balanced meal. If your toddler is ready for more complex textures, small amounts of well-cooked, finely chopped onion may be offered. Avoid serving large chunks or raw onion to reduce any digestive discomfort. Continue introducing a variety of flavors and monitor for any reactions.
