While this Cajun Blackened Fish may sound complicated (blackening a fish? huh?) it’s actually dead-simple and SO DELICIOUS. And since fish cooks quickly, this dinner can be on the table in around 20 minutes! All it requires is mixing up a few spices to make a Cajun Seasoning blend, rubbing it on the fish and cooking it quickly in a hot pan to get a nice sear! Serve this dish up with your favorite seasonal side, preferably something simple to throw together (like this Corn and Avocado Salsa) and dinner is ready!

How to Blacken Fish

Blackening refers to a cooking technique of coating something in a spice blend and then quickly searing it off in a pan. The spices take on a nice toasty flavor and it has a dramatic finish to it with a crust! You want to cook the fish off quickly so that it forms that crust and so that it just toasts the spices instead of burning them.

What is in Cajun Seasoning

We’ve used Cajun Seasoning previously in our Cajun Chicken Pasta recipe, and we’re using that tried and true blend here for this classic Cajun dish. In our blend we use these spices:

  • Paprika 
  • Garlic powder 
  • Onion powder
  • Salt
  • Cayenne
  • Black pepper 
  • White pepper

Rubbing the spice blend on the fishWhat is the best type of fish to use with this recipe

We liked using this Cajun Seasoning with cod, but most any fish can work. Even some of the stronger flavored fish like salmon can work here because the cajun seasoning is bold enough to match it. Here are some options:

  • Haddock
  • Catfish
  • Bass
  • Flounder
  • Salmon
