Branzino
Mild, soft and flaky European sea bass. Often sold whole, so take your time with the bones.
Checked against official guidance on October 18, 2026 · How we review
Quick answer
Babies can eat branzino from around 6 months, once they show signs of being ready for solids. Prepare it as shown below.
How to serve branzino by age
6 months+
Soft flakes or fish cakes
Bake or poach branzino until it is opaque and flakes easily (145°F / 63°C), remove every bone and the skin, and offer large soft flakes, or mix with mashed potato and shape into finger-sized fish cakes.
- Size
- Large soft flakes, or fish cakes shaped like a finger, about 6–8 cm long and 2 cm wide (2½–3 × ¾ in).
- Check before serving
- Run your fingers through every flake to feel for bones, including the thin pin bones. Cooked branzino is white and opaque all the way through and flakes easily with a fork.
US and UK advice differ here. The AAP suggests mashed food or soft pieces no larger than ½ inch; the NHS suggests soft finger-sized pieces your baby can hold in their fist. Both agree the food must squash easily.
9 months+
Small flakes
Offer small, boneless, fully cooked flakes for pincer-grasp practice, or stir into pasta or mashed vegetables.
- Size
- Flakes no bigger than about 1 cm (just under ½ inch).
- Check before serving
- Feel every flake for bones before serving.
12 months+
Pieces or in family meals
Serve bite-sized pieces, fish cakes, or branzino flaked into family dishes such as pasta or a fish stew. Always cook it fully, and take your child's portion out before you add salt for the adults.
- Size
- Bite-sized pieces about 1 cm (just under ½ inch), or fish cakes.
- Check before serving
- Feel every flake for bones before you mix it into a dish or shape it into cakes.
18 months+
Flaked into family meals
Serve branzino in pasta, soft tacos or fish cakes, baked rather than fried. If the family is sharing a whole roasted fish, lift your toddler's portion off the bones yourself and keep checking for bones; they're easy to miss.
- Size
- Bite-sized pieces about 1 cm (just under ½ inch).
Always have your child sit upright in a high chair or at the table, and stay with them the whole time they eat. Keep to the size and texture for their stage. Every baby develops on their own timeline.
How to prepare branzino
- 1
Buy fillets, or ask the fish counter to fillet a whole branzino and take out the pin bones. Run your fingers along each fillet and pull out any bones you feel with clean tweezers.
- 2
Bake a fillet at 200°C (390°F) for about 10 to 15 minutes, or poach it, until it's opaque and reaches 145°F (63°C) in the thickest part. Don't add salt.
- 3
Let it cool, then remove the skin and pull the flesh apart with your fingers, feeling every flake for bones.
- 4
Offer large flakes, or mix with mashed potato and shape into finger-sized cakes.
- 5
First time? Pick a day your baby is well and at home, so you can stay nearby for several hours afterward. Fish can cause a delayed reaction: see when to call the doctor.
How much to offer
For the first taste, offer a small amount: a few flakes or one small fish cake. Branzino (European sea bass) isn't on the FDA's mercury chart. For children, the FDA's advice is 2 servings of fish a week from its 'Best choices' list (about 1 oz, or 28 g, per serving at ages 1 to 3), so use 'Best choices' for your baby's usual fish meals. Our suggestion is to serve branzino only now and then. Your baby decides how much to eat.
Common mistakes
Serving straight from a whole roasted fish
Branzino is often roasted whole, with the head, skin and all its bones. Lift the flesh off the bones yourself and feel every flake with your fingers before it goes on your baby's plate. The CDC lists bones in fish as a choking hazard.
Mixing it up with other sea bass
Branzino is European sea bass, which isn't on the FDA chart. Black sea bass is a different fish and a 'Best choice'; Chilean sea bass and ocean striped bass are different fish again, and 'Good choices', with more mercury.
Undercooking it
Cook it to 145°F (63°C), until it's opaque and flakes easily. Never offer raw fish such as crudo, carpaccio or ceviche.
Serving the crispy skin
Branzino is often cooked skin-on until crisp. Take the skin off for babies: it's chewy and hard for them to break down.
Where US and UK guidance differ on branzino
United States(AAP and CDC)Your setting
European sea bass (branzino) isn't on the FDA's 'Advice about eating fish' chart, which lists black sea bass as a 'Best choice' and Chilean sea bass and ocean striped bass as 'Good choices'. For children, the FDA suggests 2 servings a week from 'Best choices' (about 1 oz each at ages 1–3), so our suggestion is to treat branzino as an occasional fish.
United Kingdom(NHS)Your setting
The NHS doesn't single out sea bass, and it isn't on the NHS oily fish list, so the NHS weekly oily fish limits don't apply. Children under 16 shouldn't have shark, swordfish or marlin. Baked, steamed or grilled fish is a healthier choice than fried.
We cover US and UK guidance in detail. Elsewhere, check your national health service's advice too.
Questions parents ask
Can branzino be a choking hazard for babies?
Cooked, flaked branzino is a low choking risk, but the CDC lists bones in fish as a choking hazard, and the NHS says to remove bones from fish for babies. Whole fish and fillets can both hide pin bones, so check every flake with your fingers before serving. Always cook branzino fully, and never offer raw or undercooked fish.
Can babies be allergic to branzino?
Fish is a common allergen. Introduce it on its own first, in a small amount, and watch for signs of a reaction. If your baby reacts to branzino, talk to your pediatrician before offering other fish: people allergic to one type of fish often react to other types (NHS).
Is branzino healthy for babies?
A source of protein: FoodData Central has no standard record for European sea bass, but one brand's label for raw European sea bass lists about 21 g of protein and 9 g of fat per 100 g. It is not a major source of iron.
Can babies eat branzino?
Yes, from around 6 months, cooked until opaque and flaky, with the skin and every bone removed. It isn't on the FDA's mercury chart, so our suggestion is to serve it now and then, and lean on 'Best choices' such as salmon, cod and pollock the rest of the time.
Is branzino the same as sea bass?
Branzino is European sea bass, and the FDA lets it be sold under the name 'sea bass'. On the FDA mercury chart, black sea bass is a 'Best choice' and Chilean sea bass and ocean striped bass are 'Good choices', but European sea bass isn't listed. If a label just says 'sea bass', ask which kind it is. See our sea bass page for the other kinds.
Can I use frozen branzino?
Yes. Thaw it in the fridge overnight, then cook it until it's opaque and reaches 145°F (63°C).
If your baby refuses branzino
- Many babies need 10 or more tries before they accept a new food. Keep offering it alongside foods they already like.
- Mix flakes into foods your baby already likes, such as mashed potato or pasta.
- Try fish cakes: they're easier to hold than loose flakes.
- Eat some yourself at the same meal. Babies copy what they see.
Never force or pressure your baby to eat. Some days they'll eat more, some days less, and that's normal.
Buying and storing branzino
- Keep raw branzino in the fridge and cook it within 2 days, or freeze it. Thaw frozen branzino in the fridge overnight.
- Cooked branzino keeps for 3 to 4 days in a covered container in the fridge.
- Fish cakes bound with potato only can be frozen for 3 to 4 months. Reheat them only once, to 165°F (74°C), until steaming hot, then let them cool before serving.
- Throw away any food left out at room temperature for more than 2 hours (1 hour if it's hotter than 90°F / 32°C).
When to talk to your doctor
Contact your pediatrician, GP or health visitor if:
- Your baby vomits a few hours after eating fish. This can be FPIES, a delayed type of food allergy that fish can trigger. If they vomited once or twice and seem alert and like themselves, call your pediatrician or GP. If they vomit again and again, or are pale, floppy, very sleepy or hard to wake, call your emergency number.
- You notice mild signs of an allergic reaction after eating, such as a few hives or a little vomiting. See signs of a reaction.
- You're worried about how much your baby eats, their growth, or they refuse most solid food for weeks.
Call 911999your local emergency number (such as 112 in Europe or 000 in Australia) now if your baby has trouble breathing, wheezing, can't cough or cry, has lips, mouth, tongue or throat that suddenly swell, or becomes pale, bluish, floppy or unresponsive. Also call if hives come with repeated vomiting.
