Can babies have mahi-mahi?
Babies can have mahi-mahi from about 6 months, fully cooked, deboned and flaked. Mahi-mahi is a fish and a common allergen, so introduce it carefully. It has moderate mercury, so offer it about once a week alongside lower-mercury fish.
How to serve mahi-mahi by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Bake, steam or poach mahi-mahi until it flakes easily and is opaque all the way through. Remove skin and bones, then mash it smooth with potato, avocado, breast milk or formula and serve it on a spoon.
7–8 months
Flake cooked mahi-mahi finely into lumpier mashed potato or avocado, or offer large soft flakes your baby can pick up. Soft fish patties made with mashed potato that fall apart easily are good to hold.
9–12 months
Offer small flakes of cooked mahi-mahi for pincer practice, or mix flakes into rice, pasta or scrambled egg. Feel each piece for bones.
12 months +
Toddlers can have mahi-mahi in fish tacos, rice bowls or fish cakes. Keep breading light and season with herbs and lemon rather than salt.
Why it’s good
Mahi-mahi gives babies lean protein, vitamin B12, niacin, selenium, phosphorus and some omega-3 fats. Its mild, firm flesh flakes easily, which makes it a friendly fish for new eaters.
Safety notes
- Cook mahi-mahi to 145°F (63°C) until it is opaque and flakes easily. Never serve raw or undercooked fish to babies.
- Mahi-mahi is in the FDA and EPA moderate mercury group. Offer it about once a week and choose lower-mercury fish like salmon, sardines and cod at other meals.
- Mahi-mahi that is not kept cold can build up histamine and cause scombroid poisoning. Buy from a trusted source, keep it refrigerated and avoid fish that smells off.
- Remove skin and check carefully for bones before serving.
Introduce mahi-mahi on its own, then keep it in
Mahi-mahi is a finned fish, and fish is one of the Top 9 food allergens. Introduce a small amount first and watch for hives, vomiting, swelling or breathing changes. Repeated vomiting 1 to 4 hours after eating can be a sign of FPIES, so call your pediatrician if that happens.
