How to Serve Blackened Cod the Whole Family

I get it, feeding kids can be tough! But following the Division of Responsibility and knowing your job and your child’s job makes it SO much more enjoyable. You’ll be able to feed your kids any meal, which will help ensure that they are eating a variety of nutritious foods – with plenty of play food sprinkled in. 😉

If your kids aren’t sure about fish, serve a tiny piece. If you think the blackening seasoning will be too much, either decrease the amount you use or omit it completely and just cook the fish portion in butter.

Helpful Tools to Make Blackened Cod

  • 12″ Nonstick Frying Pan – I prefer to cook seafood on nonstick pans as fish and seafood can be fragile.
  • Cast Iron Skillet – Use a cast iron for cast iron cod. If it sticks to pan when trying to flip, let it cook for another minute or so until it releases from pan.

    My husband liked it alot, it was a little spicy for me (even though i used only the cayenne). I also cut both the salt and sugar by half.
    I wasn’t certain what heat setting to use, i picked medium and it seemed like that was the right setting.

    We liked this blackened cod! It was tasty, with a bit of crispness on the outside and the flavor was just right, not totally overpowering. Had your airfry potatoes and asparagus with it. Another winner Emily.
