1. Wash your hands and clean a work surface. Wash the green beans and peel the sweet potato. Cut the sweet potato into thick sticks about 1–1.5 cm wide and 6–8 cm long so they are easy for a baby to hold.
2. Trim the green beans to remove ends and leave them whole or cut to the same 6–8 cm length so the baby can grip them.
3. Check the cod fillet carefully for bones and remove any you find. Cut the fillet into long strips roughly the same length as the vegetables so they are easy for little hands to hold.
4. Place a steamer basket over gently boiling water. Put the sweet potato sticks in first and steam for about 10–12 minutes, until they are very soft inside and a fork presses through easily but they still hold their shape for grasping.
5. Add the green beans to the steamer and continue steaming for another 6–8 minutes until the beans are soft enough to squish between two fingers but still intact.
6. When the vegetables are nearly done (after about 10 minutes of steaming), place the cod strips in the steamer on top of the vegetables or in a separate small heatproof dish and steam for 6–10 minutes, depending on thickness, until the fish is fully opaque and flakes easily with a fork.
7. Remove all items from the steamer and let them cool on a clean plate until lukewarm. Test the temperature yourself before offering to the baby.
8. Flake the cod with a fork and check carefully for any remaining bones. Offer whole strips of sweet potato, whole/lengthwise green beans, and long strips of flaked cod so the baby can pick them up and self-feed. Make sure pieces are an appropriate size and softness for your baby’s stage: for younger babies (closer to 4 months) you may present slightly thicker, very soft sticks they can gum; for older babies present standard finger size.
9. Always supervise closely while the baby is eating and be ready to respond if the baby gags or chokes. Do not add salt, sugar, oil, butter, or any seasoning — serve the plain cooked ingredients only.

Summary

Plain steamed cod, sweet potato sticks and green beans prepared as soft, graspable pieces for baby-led weaning. Suitable as a dinner or breakfast-style finger-food meal for babies who are ready to self-feed (typically from around 6 months; if offering earlier follow your healthcare advice).

Storing options

Cool completely then store in an airtight container in the refrigerator for up to 24 hours. Reheat thoroughly until steaming and allow to cool to lukewarm before serving. Cooked portions can be frozen in small portions for up to 1 month; thaw in the refrigerator and reheat fully before offering.

Allergies and side effects

Fish (cod) is a common allergen — introduce on its own first and watch for reactions. Always check for and remove bones. Ensure pieces are soft enough to be mashed by the baby’s gums to reduce choking risk. Always supervise feeding and consult your pediatrician about introducing fish or starting solids early, especially for babies under 6 months.
