Branzino is European sea bass, a mild white fish with tender, delicate flesh and a clean flavor that most babies take to easily. From around 6 months it is a lovely fish to introduce. Most branzino you find is farmed, which is low in mercury and fine to serve regularly; wild branzino runs higher in mercury and is better kept occasional, so it helps to know which you are buying. The one thing branzino always asks of you is care with its bones: it is often sold and cooked whole or as a fillet with small pin bones, so the real work is flaking it apart and checking every piece before it reaches your baby. Fish is one of the top-9 allergens, so the first serving is also an allergen introduction.

⚠️ Farmed branzino is low in mercury and can be a regular fish for babies, while wild branzino runs higher in mercury and is best kept occasional.1

Why it matters: Fish bones are thin and sharp enough to catch in a baby's throat, and branzino is often cooked whole or as a pin-boned fillet, so patient flaking and bone-checking is the single step that turns a delicate fish into a safe first taste, the same care you would give any fish served on the bone.

Prep School: how to prepare branzino for baby-led weaning (BLW) and purées

🍴 Baby-led weaning

6 monthsAt this age branzino works best mashed: cook it through until it flakes, flake it apart while feeling every piece for small bones, then mash it soft with a familiar vegetable and let your baby work at it from a loaded spoon.
9 months+Offer soft flaked pieces for your baby to pick up, still bone-checked, mixed with something moist like mashed potato or avocado so the flakes stick together.
12 months+Serve small bone-checked pieces of cooked branzino as part of family meals, keeping added salt low.

🥄 Purées

6 monthsCook the branzino through until it flakes, then flake it apart and check every piece for small bones. Mash into a soft puree, on its own or with a familiar vegetable, so it holds together on a spoon.
9 months+A coarser mash with soft bone-checked flakes folded through, mixed with something moist like mashed potato so it stays easy to swallow.
12 months+Small bone-checked pieces of cooked branzino folded into family meals, keeping added salt low.

Is branzino safe? Choking & prep

Farmed branzino is typically low in mercury and fine to serve on a regular basis, while wild branzino runs higher and is best kept to about once a month.1 Fish is one of the top-9 allergens, so if this is your baby's first fish, offer it on its own, earlier in the day, and watch for about two hours for signs like hives, swelling, or vomiting; any trouble breathing or swelling of the tongue or throat is an emergency, call emergency services. The main safety task with branzino is bones: cook it fully until it flakes, then flake it apart with your fingers and feel through every piece for small pin bones before serving, since a fish bone is a genuine choking and injury risk. Keep added salt low, serve warm rather than hot, and always supervise your baby while eating.

Nutrition

Branzino is a good source of lean protein and provides omega-3 fats, which support your baby's developing brain and eyes. It also carries vitamin B12 and selenium. Farmed branzino delivers this nutrition with very little mercury, so it fits well into a regular rotation; wild branzino carries more, which is why it is better kept occasional. That combination of gentle flavor, soft flaked texture, and, in the farmed form, a low-mercury profile is what makes it such a friendly fish to have on hand.

Goes well with

Mashed potato · Avocado · Sweet potato · Peas · Lemon (a small squeeze)

Storage & freezing

Keep raw branzino cold and cook it within a day or two of buying, or freeze it. Refrigerate cooked, flaked branzino in a sealed container and use it within a day, reheating only once until steaming hot all the way through, then cooling to warm before serving. Cooked fish can also be frozen in small baby portions for up to a month; thaw in the fridge and reheat thoroughly. Do not leave cooked fish sitting at room temperature.

Common questions

When can babies eat branzino?

From around 6 months, once your baby is starting solids. Cook it through, flake it, and check carefully for small bones. Because fish is a top-9 allergen, offer it on its own the first time and watch for a reaction.

Is branzino high in mercury?

It depends on whether it is farmed or wild. Farmed branzino, which is what most stores sell, is low in mercury and fine to serve your baby regularly. Wild branzino runs higher in mercury, so it is better kept to about once a month. When you can, check the label or ask which you are buying.

How do I remove the bones from branzino for my baby?

Cook the fish until it flakes, then break it apart with your fingers over a plate and feel through every flake for small pin bones before serving. Going slowly here is the whole job; a fish bone is a real choking and injury risk, so it is worth double-checking each piece.

Is branzino a common allergen?

Yes, fish is one of the top-9 allergens. Introduce branzino on its own, earlier in the day, and watch for about two hours for signs like hives, swelling, or vomiting. Any trouble breathing or swelling of the tongue or throat is an emergency, call emergency services.

How should I cook branzino for a baby?

Bake, steam, poach, or pan-cook it without added salt until the flesh is opaque and flakes easily. Then flake it, check for bones, and mash it into a soft puree for a younger baby or offer soft flaked pieces for an older one. A small squeeze of lemon is fine; skip salt and strong seasoning.

Can babies eat branzino skin?

It is best to remove the skin for babies. It can be chewy and harder to manage than the soft flesh, and taking it off also makes it easier to spot and pull out any small bones as you flake the fish.

How often can my baby eat branzino?

Farmed branzino is low in mercury, so it can be a regular fish in your baby's week, and offering fish a couple of times a week is a reasonable rhythm. Wild branzino runs higher in mercury and is better kept to about once a month. Varying which fish you serve helps round out the omega-3s and nutrients your baby gets.

My baby has a known fish allergy. Can they have branzino?

Not without medical guidance. A baby with a diagnosed fish allergy can react to branzino like any other fish, so talk to your pediatrician or allergist before offering it. If your baby has only ever reacted to shellfish, that is a separate allergen, but still check with your doctor first.
