Catfish has a reputation as a stronger, muddier fish, but farmed catfish (which is most of what you will find in a store) is actually mild, a little sweet, and firm. That firmness is a nice feature for babies: it flakes into soft, distinct pieces rather than turning to mush. It usually arrives as boneless fillets, which makes prep simple, though a quick bone check is still worth it. Fish is a top-9 allergen, so offer catfish on its own the first few times and watch how your baby responds, rather than tucking it into a busy new meal.

⚠️ Farmed catfish is low in mercury, so it is one of the fish you can serve regularly, cooked through and checked for any stray bones1.

Why it matters: Farmed catfish is low in mercury, so it can be served regularly, while cooking it fully and checking for stray bones removes the two real risks a firm-fleshed fish poses to a baby.

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

🍴 Baby-led weaning

6 monthsCook through until it flakes and looks opaque all the way through. Feel for any stray bones.
9 monthsOffer soft flaked pieces your baby can rake up and self-feed, still bone-checked.
12 months+Soft flakes your baby can pick up, still bone-checked.

🥄 Purées

6 monthsCook through until it flakes and looks opaque all the way through, then mash or flake very soft and feel for any stray bones.
9 monthsSoft flaked pieces, still bone-checked.
12 months+Flakes stirred into rice, mashed potato, or a little sauce, still bone-checked.

Is catfish safe? Choking & prep

The FDA lists catfish among its "Best Choices" for low-mercury fish, so it is a safe pick to offer regularly rather than a food to ration1. Cook it fully until the flesh is opaque and flakes easily, since undercooked fish can carry bacteria that hit babies harder than adults. Farmed catfish is usually sold as boneless fillets, but break the cooked fish into small flakes and run your fingers through them over a plate anyway, because even a "boneless" fillet can hide a stray bone. Because fish is a top-9 allergen, introduce it on its own, earlier in the day when you can watch for a couple of hours, and look for signs of a reaction like hives, swelling, or vomiting.

Nutrition

Catfish is a lean source of protein along with vitamin B12, selenium, and phosphorus, which support growth, a healthy nervous system, and strong bones. It carries less omega-3 than oily fish like salmon, so think of it as an easygoing, everyday fish rather than an omega-3 powerhouse, and rotate in oilier fish across the week for that.

Mashed potato · Peas · Carrot · Rice · Sweet corn

Storage & freezing

Cooked catfish keeps 1 to 2 days in the fridge and freezes well. Keep it cold until you serve it, and do not leave cooked fish sitting at room temperature.

Common questions

Can babies eat catfish?

Yes, from around 6 months, once it is cooked all the way through and flaked soft. Farmed catfish is mild and low in mercury, which makes it a friendly first fish. Because fish is a top-9 allergen, offer it on its own the first few times so you can watch for any reaction.

Is catfish high in mercury?

No. The FDA lists catfish among its Best Choices for low-mercury fish, so farmed and shop-bought catfish is one you can serve regularly, unlike high-mercury fish such as shark or king mackerel. FDA does flag catfish caught by family or friends as worth checking against your local fish advisory first.

Is catfish a good first fish?

It is a good one. Farmed catfish is mild and firm, so it flakes into soft, distinct pieces that many babies take to more readily than stronger, oilier fish.

Catfish fillets say boneless. Do I still need to check for bones?

Yes, quickly. Boneless fillets are very reliable, but a stray pin bone can slip through, so break the cooked fish into small flakes and feel through them over a plate in good light before serving.

How do I know catfish is cooked enough?

It should look opaque all the way through and flake easily when you press it with a fork. Cooking it fully matters because undercooked fish can carry bacteria that babies handle less well than adults.

Does catfish have much omega-3?

Less than oily fish like salmon or mackerel. Catfish is a lean, easygoing fish, so serve it for its protein and B12, and rotate in oilier fish over the week if you want more omega-3.

What allergic reactions should I watch for?

Common signs include hives, redness, swelling around the mouth, vomiting, or coughing and wheezing. Offer catfish earlier in the day at home so you can keep an eye out for a couple of hours. If your baby has trouble breathing or the face swells, seek emergency care right away.

My family has a fish allergy. Should I still offer catfish?

Talk to your pediatrician first. A strong family history of allergy is worth a conversation before introducing a top-9 allergen, and your doctor can help you decide on the safest way and setting to try it.

Should I introduce catfish separately from shellfish?

Yes. Finned fish like catfish and shellfish such as shrimp are two different allergens, so keeping them apart for the first few tries means that if a reaction happens, you know which food caused it.
