How to serve halibut by age

6 months+

Soft flakes or fish cakes

Bake or poach halibut 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. Cooked halibut 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.

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 halibut

1
Bake a skinless halibut 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.
2
Let it cool, then pull it apart with your fingers, feeling every flake for bones. Remove any skin.
3
Offer large flakes, or mix with mashed potato and shape into finger-sized cakes.
4
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. Halibut is on the FDA's 'Good choices' list, which has more mercury than its 'Best choices'. For children, the FDA's advice is 2 servings of fish a week from the 'Best choices' list (about 1 oz, or 28 g, per serving at ages 1 to 3). It gives no 'Good choices' amount for children: its '1 serving and no other fish that week' rule is for adults who are pregnant or breastfeeding. So use 'Best choices' for your baby's usual fish meals. Our suggestion is to serve halibut only now and then. Your baby decides how much to eat.

Common mistakes

Making it the everyday fish

Halibut is a 'Good choice' on the FDA list, not a 'Best choice', and the FDA's advice for children is to choose fish from the 'Best choices' list. For most meals, pick low-mercury fish such as salmon, cod, pollock or trout, and keep halibut as an occasional meal.

Missing bones

Halibut steaks and fillets can still hold bones. Feel every flake with your fingers, even in fillets sold as boneless.

Undercooking it

Cook it to 145°F (63°C), until it's opaque and flakes easily. Never offer raw fish such as sushi or ceviche.

Relying on battered or fried fish

Baked, steamed or poached fish is a healthier choice than fried, and batter adds fat. Bake or poach halibut instead.

Where US and UK guidance differ on halibut

United States(AAP and CDC)Your setting

Halibut is on the FDA's 'Good choices' list, with more mercury than 'Best choices'. For children, the FDA suggests 2 servings a week from 'Best choices' (about 1 oz each at ages 1–3) and gives no 'Good choices' amount for children. Its '1 serving of a Good choice and no other fish that week' rule is for pregnancy and breastfeeding, so our suggestion is to treat halibut as an occasional fish for your child.

United Kingdom(NHS)Your setting

The NHS doesn't single out halibut. Children under 16 shouldn't have shark, swordfish or marlin. The NHS weekly limits are for oily fish, and halibut isn't on its oily fish list. 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 halibut be a choking hazard for babies?

Cooked, flaked halibut is a low choking risk, but bones are a hazard. Check every flake with your fingers before serving. Always cook halibut fully, and never offer raw or undercooked fish.

Can babies be allergic to halibut?

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 halibut, talk to your pediatrician before offering other fish: people allergic to one type of fish often react to other types (NHS).

Is halibut healthy for babies?

A lean source of protein, with selenium and some vitamin D: FoodData Central lists about 55 µg of selenium and 5.8 µg of vitamin D per 100 g of cooked Atlantic or Pacific halibut. It has less omega-3 fat than oily fish such as salmon, and it is not a major source of iron.

Can babies eat halibut?

Yes, from around 6 months, cooked until opaque and flaky, with every bone removed. It's on the FDA's 'Good choices' list, so our suggestion is to serve it now and then rather than every week, and lean on 'Best choices' such as salmon, cod and pollock the rest of the time.

Is halibut high in mercury?

It's in the middle. The FDA lists halibut as a 'Good choice': higher in mercury than its 'Best choices', but not one of the fish to avoid. Shark, swordfish and marlin are the ones both US and UK advice say never to give children.

Can I use frozen halibut?

Yes. Thaw it in the fridge overnight, then cook it until it's opaque and reaches 145°F (63°C).

If your baby refuses halibut

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, rice 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 halibut

Keep raw halibut in the fridge and cook it within 2 days, or freeze it. Thaw frozen halibut in the fridge overnight.
Cooked halibut keeps for 3 to 4 days in a covered container in the fridge. Rice dishes are the exception: cool them within 1 hour, keep them in the fridge for no more than 1 day, and reheat them only once.
Fish cakes 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.
