How to serve grouper by age

Grouper for 6 months+: soft flakes or fish cakes

6 months+

Soft flakes or fish cakes

Bake or poach grouper until it is opaque and flakes easily (145°F / 63°C), remove the skin and every bone, then break it into soft flakes. Its flesh is firm, so mash the flakes with a fork into mashed potato or another food your baby eats, or shape into finger-sized fish cakes.

Size
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. Squash a flake between your thumb and finger: it should break apart easily. If it's firm or dry, mash it into a moist food.

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 grouper

  1. 1

    Buy grouper from a cold counter or the freezer, and get it into the fridge quickly.

  2. 2

    Bake a skinless 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. 3

    Let it cool, then pull it apart with your fingers, feeling every flake for bones. Remove the skin.

  4. 4

    Mash flakes into a soft food, or mix with mashed potato and shape into finger-sized cakes.

  5. 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. Grouper 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 grouper only now and then. Your baby decides how much to eat.

Common mistakes

Making it the everyday fish

Grouper 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. Our suggestion is to keep grouper as an occasional meal.

Serving big firm chunks

Grouper is firmer than cod or salmon. Flake it and mash it into a soft food at 6 months, and keep pieces no bigger than about 1 cm (just under ½ inch) from 9 months.

Undercooking it

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

Missing bones

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

Where US and UK guidance differ on grouper

United States(AAP and CDC)Your setting

Grouper 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 grouper as an occasional fish for your child.

United Kingdom(NHS)Your setting

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

Cooked, flaked grouper 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. Its flesh is firm, so flake it small or mash it for babies, and check every flake with your fingers before serving. Always cook grouper fully, and never offer raw or undercooked fish.

Can babies be allergic to grouper?

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

Is grouper healthy for babies?

A lean source of protein and selenium: FoodData Central lists about 25 g of protein and 47 µg of selenium per 100 g of cooked grouper (mixed species), with little fat (about 1.3 g). It has less omega-3 fat than oily fish such as salmon, and it is not a major source of iron (about 1.1 mg per 100 g).

Can babies eat grouper?

Yes, from around 6 months, cooked until opaque and flaky, with every bone removed and the firm flesh flaked small or mashed. 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 grouper high in mercury?

It's in the middle. The FDA lists grouper 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.

Is grouper safe when we travel?

In its travel advice, the CDC lists grouper among the reef fish you may want to avoid because of ciguatera, a toxin from tiny algae around coral reefs. It doesn't change how the fish looks, tastes or smells, and cooking doesn't destroy it. When you're traveling in reef areas, our suggestion is to choose a different fish for your child. Symptoms such as nausea, vomiting, diarrhea or tummy pain usually start 3 to 6 hours after eating, but can start up to 30 hours later; the CDC says to seek medical care if they start after eating fish.

Can I use frozen grouper?

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

If your baby refuses grouper

  • 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 grouper

  • Keep raw grouper in the fridge and cook it within 2 days, or freeze it. Thaw frozen grouper in the fridge overnight.
  • Cooked grouper 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.
