Arctic char is a close cousin of salmon and trout, and it acts like one on the plate: soft pink flesh that flakes easily once cooked, with a milder, sweeter taste that many babies take to right away. It is naturally low in mercury, so you can serve it regularly rather than saving it for now and then, and it is rich in the omega-3 fats that support a growing brain and eyes. Two things earn a moment of care. Fish is a top-9 allergen, so you introduce it on its own, and char carries fine pin bones you need to find and pull. Neither is a reason to skip it. They are just the reason you slow down for a minute the first few times.
Why it matters: Arctic char tests low in mercury, so this salmon relative can be served regularly; the care is in cooking it through and pulling every pin bone.

Is arctic char safe? Choking & prep
Fish is one of the nine major food allergens recognized by the U.S. FDA, which also advises that children eat lower-mercury fish regularly1, so offer arctic char on its own on a calm day, ideally earlier in the day. Most reactions show up within minutes to 2 hours, so give it a few days before you add another new food, and once arctic char has gone well, keep it in your baby's usual rotation. Cook it through, to 158°F (70°C) on a food thermometer,5 or until it flakes and is opaque all the way, then flake the fish apart slowly and run your fingers through it to feel for the fine pin bones, every time, even with fillets sold as boneless. Call 911 (or your local emergency number) right away if any of these show up soon after a food, on their own or together: swelling of the lips, face, eyes, or tongue; swelling or tightness in the throat, or trouble swallowing; vomiting; hives that spread beyond the mouth and face; trouble breathing, noisy breathing, or wheezing; a cough that keeps going; a hoarse voice; skin or lips that turn pale or blue; or a baby who goes floppy or limp, or is suddenly sleepy or hard to wake. If the only sign is a new rash or a few hives around the mouth or face, stop the food, watch your baby closely, and call your pediatrician. If anything else about your baby worries you, call 911.

Nutrition
Arctic char is a genuinely strong food for a baby. As a member of the salmon family it is a great source of DHA omega-3 for brain and eye development, along with protein and vitamin D, and it is one of the lower-mercury fish. That last part matters: char tests low in mercury,3 which is exactly why it can be a regular part of the week rather than an occasional food. There is no meaningful nutritional catch here. The care is all in the cooking and the bones, not the fish itself.
Goes well with
Potato · Peas · Broccoli · Rice · Carrot · Lemon (a squeeze, not salt)
Storage & freezing
Cooked arctic char keeps 1 day in the fridge, or 1 to 2 months in the freezer.2 Store it in a sealed container. Cool it quickly, reheat until piping hot, and do not refreeze fish that has already been thawed.

Common questions
Can babies eat arctic char, and when?
Yes, from around 6 months, once your baby is starting solids. Cook it through, flake it soft, and remove every pin bone. Introduce it deliberately as a fish allergen.
Is arctic char low in mercury?
Yes. Arctic char tests low in mercury, which is why it is a lovely regular choice for babies.3 If your char was caught by family or friends rather than bought, check the local fish advisory first, and if there is none, make it the only fish that week.1
Is arctic char related to salmon?
Yes. Arctic char is a close cousin of salmon and trout, in the same fish family, with similar soft pink flaky flesh and plenty of omega-3. You can prepare it much the same way. Char often has a slightly milder, sweeter taste.
Is arctic char a good first fish for babies?
It is one of the nicer ones to start with. It is low in mercury, rich in omega-3, and its soft pink flesh flakes easily once it is cooked through and boned, which suits little mouths.
How do I remove the bones from arctic char?
Flake the cooked fish apart slowly and run your fingers through it, feeling for the fine pin bones, then pull each one out. Do this every time, even with fillets labeled boneless, because a stray bone is easy to miss.
How do I introduce arctic char as an allergen?
Offer a small amount on its own on a calm day, ideally earlier in the day rather than right before bed, so you can watch your baby closely for the next couple of hours, when most reactions show up. Give it a few days before you add another new food, and once arctic char has gone well, keep it in the rotation. Signs of a reaction can include hives, swelling, vomiting, or trouble breathing. Call 911 (or your local emergency number) right away if any of these show up soon after a food, on their own or together: swelling of the lips, face, eyes, or tongue; swelling or tightness in the throat, or trouble swallowing; vomiting; hives that spread beyond the mouth and face; trouble breathing, noisy breathing, or wheezing; a cough that keeps going; a hoarse voice; skin or lips that turn pale or blue; or a baby who goes floppy or limp, or is suddenly sleepy or hard to wake. If the only sign is a new rash or a few hives around the mouth or face, stop the food, watch your baby closely, and call your pediatrician. If anything else about your baby worries you, call 911.
Does arctic char need to be fully cooked for babies?
Yes. Cook it through until it flakes easily and is opaque all the way, with no translucent center. Undercooked fish carries a food-safety risk, so avoid raw or lightly cooked char for babies.
How should I serve arctic char to a baby?
Cook it through, flake it soft, and check carefully for bones, then mash it into a puree or mix small flakes through potato, rice, or a soft vegetable. Once it is cooked and boned, char is soft and not a major choking risk on its own.
How often can my baby have arctic char?
Because it is low in mercury, arctic char can be part of a varied diet a couple of times a week. That is one of the reasons it earns a regular spot rather than being limited like higher-mercury fish.
Can babies eat smoked or cured arctic char?
Skip refrigerated smoked or cured char for babies and young children, and not mainly because of the salt. It can carry Listeria, and the CDC lists refrigerated smoked fish among the foods to avoid for people at higher risk, with smoked fish cooked into a hot dish as the safer choice.4 Plain fresh or frozen arctic char cooked through is the better pick.
