Safety Information
Always read the safety guidance before servingHow to Serve Onion to a 6–9 Months Old
Milestones for 6–9 monthsFine to serve
Suitable at this age with the usual preparation described below.
How to Cut
For babies 6-9 months, onion should be cooked until very soft (steamed, sautéed, or roasted) to enhance sweetness and reduce sharpness. Puree or mash well. You can also finely chop or mince and mix into other purees or mashed foods like potato, lentils, or soft vegetables. Thinly sliced, whole pieces of raw or firm-cooked onion are not recommended due to strong flavor and texture. Always start with a small amount mixed into other foods to gauge your baby’s acceptance and digestive comfort.
Serving Instructions
Offer onion in very small amounts as part of a mixed meal with iron-rich foods, soft vegetables, and a source of healthy fat. For a balanced meal, try combining 10-15 g (1-2 tablespoons) of well-cooked, pureed onion mixed with 20 g (about 1.5 tablespoons) of cooked lentils, 20 g (1.5 tablespoons) of mashed sweet potato, and 1 tsp (5 ml) olive oil. Onion adds subtle flavor, fiber, and vitamin C to support iron absorption and gentle digestion.
How to Serve Onion to a 9–18 Months Old
Milestones for 9–12 monthsFine to serve
Suitable at this age with the usual preparation described below.
How to Cut
From 9-18 months, continue to offer well-cooked onion, either mashed, finely chopped, or incorporated into soft foods. You can also offer onion in very small, soft-cooked pieces as finger food, ensuring that each piece is no larger than 0.5 cm cubes (around 1/4 inch) to minimize choking risk. Avoid raw or firm pieces at this stage. Always supervise and observe how your child manages different textures and flavors.
Serving Instructions
Include soft-cooked onion as part of balanced meals. Offer 15-20 g (1-2 tablespoons) of well-cooked, finely chopped onion with 30 g (2 tablespoons) of cooked rice or small pasta, 30 g (2 tablespoons) of mixed vegetables, and 10 g (2 teaspoons) of cooked ground meat or tofu. Onion’s mellow flavor supports adventurous eating, adds fiber, and vitamin C to promote iron absorption and gut health.
How to Serve Onion to a 18+ Months Old
Milestones for 18–24 monthsFine to serve
Suitable at this age with the usual preparation described below.
How to Cut
After 18 months, most toddlers can handle slightly larger pieces of cooked onion, but continue to serve it well-cooked and cut into small, manageable pieces (no larger than 1 cm or 1/2 inch). You can introduce sautéed, roasted, or even lightly grilled onions for variety, but be cautious with raw onion, which may still be tough on digestion and strong in flavor. Always supervise, especially when introducing new textures or forms.
Serving Instructions
At this stage, you can continue to expand textures and flavors. Offer 20-25 g (2-3 tablespoons) of cooked onion alongside 35 g (2.5 tablespoons) of soft grains or noodles, 35 g (2.5 tablespoons) of assorted vegetables, and 15 g (1 tablespoon) of cooked fish, meat or beans. Onion can also be mixed into omelets, casseroles, or small salads (introduce finely chopped and only a few raw pieces at first). Continue to serve as part of a colorful, nutrient-rich plate to encourage balance and taste exploration.

Purée or baby-led weaning is the question parents agonise over, and the trial evidence says it barely matters. Choking, allergen timing and what stays off the plate are the decisions that do — here is the map of all of them.
