Tuna steak cooked for 6–8 months
Tuna steak can be introduced as soon as your baby is ready to start solid foods, which is typically around 6 months of age. Fish is a common allergen, so it's important to introduce tuna on its own and watch for any signs of an allergic reaction. Choose fresh or frozen tuna steak and cook it thoroughly until it flakes easily and reaches an internal temperature of 63°C.
How to serve at 6–8 months
Cook the tuna steak thoroughly until it flakes easily, then offer it in finger-length strips about the size of two adult fingers placed together, or shred it into larger flakes that your baby can grasp in their palm. Ensure the tuna is moist and tender, removing any tough outer edges or dry bits. You can serve it plain, brushed lightly with olive oil, or alongside mashed avocado or cooked vegetables.
Nutrition highlights
Tuna steak is an excellent source of high-quality protein, which supports growth and development in babies. It provides omega-3 fatty acids, particularly DHA, which are important for brain and eye development. Tuna also contains selenium, vitamin B12, and niacin, though it's worth noting that large tuna species can contain higher levels of mercury, so offering a variety of fish is sensible.
Lower-risk serving reminders
Cooked tuna steak has a low choking risk when prepared properly because it flakes into soft, moist pieces that are easy for babies to manage. The tender texture breaks down well in the mouth, though care should be taken to remove any dry or overcooked edges which can be harder to handle.
Allergen information
Fish, including tuna, is a common allergen and should be introduced carefully as part of your baby's varied diet. Offer tuna on its own the first time without mixing it into other new foods, and watch for signs of an allergic reaction such as hives, vomiting, or difficulty breathing.

Common questions
How do I prevent tuna steak from drying out for my baby?
Cook tuna just until it reaches 63°C and flakes easily, then serve it immediately or store it with a small amount of liquid such as olive oil or unsalted broth to keep it moist. Avoid overcooking, which makes tuna dry and harder for babies to manage.
Should I worry about mercury in tuna steak for my baby?
Fresh tuna steaks, particularly from larger species like yellowfin or bigeye, can contain moderate levels of mercury, so it's sensible to offer tuna occasionally as part of a varied diet that includes lower-mercury fish such as salmon or cod. Current UK guidance does not restrict tuna for babies, but variety is key.
Can I use leftover tuna steak for my baby?
Yes, leftover cooked tuna steak can be served to your baby as long as it has been stored properly in the fridge and used within two days. Reheat it gently or serve it cold, ensuring it remains moist and tender.
General feeding checklist
- Seat baby upright and stable for all meals.
- Model slow chewing and allow baby to control pace.
- Stop and reset if baby is upset, tired, or over-stuffed.
Readiness signs to check
- Baby can sit upright with minimal support during meals.
- Hands and mouth coordinate for bringing food to the mouth.
- Tongue-thrust reflex is reduced, so food is not immediately pushed out.
- Interest in self-feeding and opening mouth for food cues is visible.
Pause and seek advice if
- Coughing is persistent or distress does not settle quickly during meals.
- You notice repeated vomiting, rash, swelling, wheeze, or breathing changes after a food.
- Baby struggles with swallowing progression over multiple meals despite texture adjustments.
- There is a known medical condition affecting feeding, growth, or airway safety.
