Walleye is a favorite off the dock across the northern lakes for a reason: it is a mild, delicate white fish with a soft, clean flavor that does not announce itself the way stronger, oilier fish do. Cooked through, it flakes into tender pieces that a baby can gum and swallow, so a small taste now and then makes a friendly fish. There is one wrinkle worth knowing. Walleye is a freshwater fish and a predator that eats other fish, which is exactly the kind of fish that tends to build up more mercury, so it does not land on the everyday best choices list. Most walleye you buy is wild-caught from the Great Lakes or Canadian waters rather than farmed, and mercury in freshwater fish depends a lot on the specific lake it came from, so the safest move is to keep walleye occasional and glance at your state or local fish advisory before you make it a habit. Beyond that, the work is the same as any fish: cook it fully, hunt for bones, and because fish is a top-9 allergen, offer it on its own the first few times so you can watch how your baby does.

⚠️ Walleye is a mild freshwater white fish, but it is a predatory fish that carries moderate mercury and is not on the FDA and EPA best choices list, so serve it now and then rather than often, check your local fish advisory, and because fish is a top-9 allergen, offer it plain, cooked through, and fully deboned the first few times1.

Why it matters: Walleye is mild and soft when cooked, so it makes a gentle taste, but it is a predatory freshwater fish that carries moderate mercury and is not on the FDA and EPA best choices list, which is why it belongs in an occasional slot, should clear a local advisory when wild-caught, and like any fish should be cooked through, hand-checked for bones, and introduced plain because fish is a top-9 allergen.

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

🍴 Baby-led weaning

6 monthsCook to 158°F (70°C) on a food thermometer,6 or until it flakes and looks opaque all the way.3 Remove every bone, then serve very soft flakes your baby can rake up.
9 monthsSoft flakes your baby can rake up, still bone-checked, served plain.
12 months+Bone-checked flakes stirred into rice, potato, or a little unsalted sauce for your baby to pick up.

🥄 Purées

6 monthsCook to 158°F (70°C) on a food thermometer,6 or until it flakes and looks opaque all the way,3 then mash it very soft. Remove every bone first.
9 monthsSoft flakes mashed for spooning, still bone-checked, served plain.
12 months+Bone-checked flakes stirred into rice, potato, or a little unsalted sauce and spoon-fed.

Is walleye safe? Choking & prep

The FDA and EPA advice about eating fish covers mercury, and it notes that mercury levels vary and that locally caught fish should be checked against a local advisory, and if there is no advisory, to eat only one serving and no other fish that week1. Walleye is a predatory freshwater fish that tends to carry more mercury and is not on their best choices list, so treat it as an occasional fish rather than an everyday one, and check your state or local advisory before serving it regularly, since freshwater mercury varies by water body. The rest is standard: cook it to 158°F (70°C) on a food thermometer,6 or until it flakes and looks opaque all the way through,3 since undercooked fish can carry bacteria that hit babies harder than adults, and break the cooked fish into small flakes to run your fingers through over a plate in good light, because even a fillet can hide a stray pin bone. Because fish is a top-9 allergen, introduce plain walleye on its own, earlier in the day, and watch for signs of a reaction like hives, swelling, or vomiting. 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

Walleye gives babies lean protein along with vitamin B12 and selenium, which support growth and a healthy nervous system. It carries some omega-3, though less than oily fish like salmon or sardines, so think of it as a treat-now-and-then fish rather than an omega-3 powerhouse. Because it sits on the higher-mercury side for a freshwater fish, it works best as one fish in a varied rotation rather than a regular, and leaning on lower-mercury best choices like salmon most of the time both rounds out the omega-3 and keeps mercury low.

Storage & freezing

Cooked fish keeps 1 day in the fridge, or 1 to 2 months in the freezer.2 It freezes well. Keep raw fillets cold and cook them within a day or two of buying, or freeze fresh-caught fillets promptly if you are not cooking them soon.

Common questions

Can babies eat walleye?

Yes, from around 6 months, once it is cooked through and fully deboned. Walleye is a mild freshwater white fish, so it makes a gentle taste, but it carries moderate mercury, so keep it occasional. Because fish is a top-9 allergen, offer plain walleye on its own the first few times so you can watch for any reaction, and check a local advisory before serving it regularly.

Is walleye a good first fish?

The flavor and texture are lovely for a beginner: mild, and soft-flaking when cooked, which many babies take to more readily than stronger, oilier fish. The catch is mercury. Walleye is a predatory freshwater fish that carries more mercury and is not on the FDA best choices list, so a lower-mercury fish like salmon is a better everyday first fish, with walleye as an occasional one.

Is walleye high in mercury?

It is on the higher side for a freshwater fish. Walleye is a predator that eats other fish, which is the kind that builds up more mercury, and it is not on the FDA and EPA best choices list. Mercury also varies by the specific lake, so keep walleye occasional and check your state or local advisory before serving it often.

Do I need to check a fish advisory for store-bought walleye?

It is worth it. Most walleye sold in stores is wild-caught from the Great Lakes or Canadian waters rather than farmed, and mercury varies by water body, so it is not the clean everyday choice a farmed low-mercury fish would be. Keep it occasional, and check your state or local advisory before serving it regularly.

How do I get all the bones out?

Cook the fillet, then break it into small flakes and press each one between your fingers over a plate in good light. That is the reliable way to catch the thin pin bones that a quick glance can miss.

How do I know walleye is cooked enough?

The thickest part should read 158°F (70°C) on a food thermometer.6 Without one, it should flake easily with a fork and look opaque all the way through, with no translucent or glassy center.3 Cooking it fully matters because undercooked fish can carry bacteria that hit babies harder than adults.

How often can babies eat walleye?

Keep it occasional, about once a month at most. Walleye is a top predator, and fish at the top of the food web tend to carry the most mercury;5 Wisconsin, for example, advises one walleye meal a month for children under 15 for walleye from its inland lakes.4 For walleye caught by family or friends, follow your local advisory, and if there is none, make it the only fish your baby has that week.1 Lean on lower-mercury Best Choices like salmon the rest of the time.

Does walleye have much omega-3?

Some, but modestly, less than oily fish like salmon or sardines. Think of walleye as an occasional fish and lean on lower-mercury oily fish across the week for more omega-3 with less mercury.

What allergic reactions should I watch for?

Common signs include hives, redness, swelling around the mouth, vomiting, or coughing and wheezing. Offer walleye earlier in the day at home so you can keep an eye out for a couple of hours. 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.
