How to serve crawfish by age

Crawfish for 6 months+: minced crawfish or crawfish cakes

6 months+

Minced crawfish or crawfish cakes

Cook crawfish plain until the tail meat is firm, pearly and opaque, peel it completely, then mince it very finely and stir into mashed potato or rice, or shape the mixture into finger-sized cakes.

Size
Finely minced into soft food, or crawfish cakes shaped like a finger, about 6–8 cm long and 2 cm wide (2½–3 × ¾ in).
Check before serving
Rub the minced crawfish between your fingers before mixing it in: you shouldn't feel any hard or sharp bits of shell. Crawfish cakes should flatten when you squash them gently.

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 crawfish

  1. 1

    Buy frozen cooked tail meat, or live crawfish from a shop. Thaw frozen tail meat in the fridge overnight, and rinse live crawfish under cold running water. Keep raw crawfish and their juices away from cooked food.

  2. 2

    Cook live crawfish in plain, unsalted water, without boil seasoning, until the tail meat is firm, pearly and opaque (145°F / 63°C). Heat precooked tail meat until steaming hot, 165°F (74°C).

  3. 3

    Let it cool, then peel every tail completely, pull out the dark vein along the back, and pick through the meat for bits of shell.

  4. 4

    Mince finely (6 months) or chop small (9 months+), and mix into a soft food or shape into cakes.

  5. 5

    First time? Pick a day your baby is well, at home, when you can watch them for a couple of hours afterward.

How much to offer

For the very first taste, offer a small amount: a teaspoon of minced crawfish mixed into a food your baby already eats. If there's no reaction, offer more next time. For ages 1 to 3, the FDA suggests a fish or shellfish serving of about 1 oz (28 g), twice a week. Your baby decides how much to eat.

Common mistakes

Serving crawfish from a seasoned boil

Crawfish boils are usually cooked in heavily salted, spicy water. The NHS says not to add salt to your baby's food or cooking water, and the AAP says babies' food should be cooked with no added salt or seasoning. Cook your baby's crawfish separately in plain water, or take out plain tail meat before the seasoning goes in.

Missing bits of shell

Crawfish shell is hard and sharp, and pieces break off easily when you peel. Pick through every portion with your fingers, even frozen tail meat sold as peeled.

Undercooking it

Cook crawfish until the tail meat is firm, pearly and opaque. The CDC says never to eat raw freshwater crayfish and to cook them to at least 145°F (63°C), because crayfish that is raw, partly cooked, pickled or salted can spread a lung fluke parasite.

Serving whole tails

Whole tails are firm and springy, and the CDC lists tough or large chunks of meat as a choking hazard. Mince them for babies and chop them small for toddlers.

Questions parents ask

Can crawfish be a choking hazard for babies?

Whole crawfish tails are firm and springy, and pieces of shell are hard and sharp. Peel every tail completely, pick through the meat for shell, mince it for babies and cut it into small pieces for toddlers. Never hand young children crawfish in the shell. Never offer raw or undercooked shellfish. Stay with your child during meals.

Can babies be allergic to crawfish?

Shellfish is a common allergen, and crawfish (also called crayfish or crawdads) are crustaceans, like shrimp, crab and lobster: the shellfish group behind most shellfish reactions (ACAAI, FARE). Shellfish can be introduced from around 6 months, like other foods: start with a small amount on its own and watch for signs of a reaction. A shellfish allergy is different from a fish allergy: one doesn't mean the other. FARE says most people allergic to one group of shellfish are allergic to other types, and the ACAAI says shellfish allergy typically lasts a lifetime, so talk to your pediatrician if your baby reacts. In the US, crustacean shellfish such as crawfish must be named on food labels, by type (FARE). If your child has breathing trouble or swelling of the face, lips or tongue, or becomes floppy after eating crawfish, call your emergency number.

Is crawfish healthy for babies?

A lean source of protein, with vitamin B12, selenium and copper: FoodData Central lists about 17 g of protein and 37 µg of selenium per 100 g of cooked wild crawfish. Plain cooked crawfish is low in sodium (about 94 mg per 100 g, or about 0.2 g of salt). It is not a major source of iron.

When can babies eat crawfish?

From around 6 months, cooked plain until firm and opaque, peeled completely and minced finely. The CDC lists shellfish among the allergenic foods to introduce when you introduce other foods, and the NHS says not to give babies raw or lightly cooked shellfish.

Are crawfish and crayfish the same?

Yes. FARE lists crawfish, crawdad, crayfish and ecrevisse as names for the same crustacean shellfish.

Can my toddler eat crawfish from a crawfish boil?

It's best to take out plain crawfish before the salt and spice go in, since boil water is usually very salty and spicy. The NHS says children aged 1 to 3 should have no more than 2 g of salt a day. If the crawfish has already been boiled in seasoning, offer only a small taste now and then, peeled and chopped small.

Is crawfish high in mercury?

No. Crawfish is on the FDA's 'Best choices' list and among the seafood it names as even lower in mercury.

If your baby refuses crawfish

  • Many babies need 10 or more tries before they accept a new food. Keep offering it alongside foods they already like.
  • Mix minced crawfish into foods your baby already likes, such as rice, pasta or mashed potato.
  • Try crawfish cakes: they're easier to hold than loose pieces.
  • If your baby keeps refusing crawfish and you're relying on it as an early allergen, mention it to your pediatrician.

Never force or pressure your baby to eat. Some days they'll eat more, some days less, and that's normal.

Buying and storing crawfish

  • Keep frozen tail meat in the freezer until you need it. Keep raw crawfish in the fridge and cook them within 2 days.
  • Cooked crawfish 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.
  • Crawfish 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 has had any reaction to crawfish, even a mild one. Stop offering it, and talk to your pediatrician before trying other shellfish such as shrimp, crab or lobster.
  • Your child develops diarrhea and tummy pain in the days or weeks after eating crawfish that was raw, undercooked, pickled or only salted, sometimes followed by fever, chest pain or tiredness. The CDC says these can be signs of a lung fluke infection, which is treatable: tell your pediatrician what they ate. If your child is confused, very sleepy or hard to wake, call your emergency number: the CDC says the fluke can reach the brain and spinal cord and cause meningitis.
  • 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.
