Blackened Fish Recipe
Quick and easy dinner recipe alert, my friends! We're cooking up some fish fillets in the Chili Pepper Madness kitchen tonight, and it's going to be fast.
Tonight we're making Blackened Fish, and it's bound to become of your favorite go-to cooking methods.
What is Blackening?
Blackening is a simple cooking method of coating the star of your dish with butter, seasoning it generously with homemade blackening seasoning, then searing it over high heat to form a nice spicy crust. This cooking method works wonderfully with fish and cooks up in no time.
The result is big flavor and huge satisfaction, a meal you won't soon forget! I think you'll love it so much that it will enter your regular cooking routine.
It has for me!
Let's talk about how to make blackened fish, shall we?

Blackened Fish Ingredients
FOR THE BLACKENING SEASONING
- Chili Powders. Use 2 tablespoons smoked paprika (or use regular paprika) + 1 tablespoon cayenne powder (use more for a spicier blend)
- Spices. Use 1 tablespoon onion powder, 1 teaspoon garlic powder, 1 teaspoon ground black pepper and 1 teaspoon sea salt
- Herbs. Use ½ teaspoon dried basil, ½ teaspoon dried oregano and ½ teaspoon dried thyme
FOR THE FISH
- Fish Fillets. 4 fillets, 6 ounces each, skinless - I used Icelandic cod today, but any fish fillet will do for this recipe.
- Melted Butter. ¼ cup.
How to Blacken Fish - the Recipe Method
Make the Blackening Seasoning. Mix all of the blackening spices together in a small bowl. Make sure it is blended evenly. You'll have extra seasoning for this recipe, so store the remainder in airtight jars or containers.
It's great on so many things!
Butter and Season the Fish Fillets. Brush one side of each fish fillet generously with melted butter and generously spoon on the blackening seasoning. Use a couple tablespoons, or really as much as you'd like.
Make it as spicy as you want. You can easily dip each fillet of fish into a shallow dish filled with seasoning to get a good, even coating.
Get Cooking. Heat a heavy cast iron skillet to medium-high heat and add the fish fillets, buttery-seasoned side down. Cook 3-5 minutes to blacken.
Brush or drizzle on the remaining butter, then generously add more seasoning.
Flip the fish fillet and cook another 2-3 minutes, or until the fish is cooked through and flaky. Usually just a few minutes on each side is enough to cook the fish through, depending on thickness.
Cook them to 145 degrees F internal temperature minimum.
Serve!

Boom! Done! Blackened fish is ready to serve. This one is SO GOOD. Such a great recipe. Just look at all that wonderful flavor and seasoning. Yum. Grab some Tartar Sauce for dipping!
Recipe Tips & Notes
- The Fish. This recipe will work with ANY type of fish. I have made this with all sorts of fish, from blackened salmon to cod, monkfish, tilapia, blackened sheepshead, redfish, swordfish, so many others. You name it! Use your favorite fish.
- The Blackening Seasoning. This is my own homemade blackening seasoning recipe, but you can very easily alter it to fit your own preferences. Sometimes I like to slip in a bit of ghost pepper powder to heat things up nicely. Feel free to adjust with other ingredients, or use a good Cajun Seasoning or Creole Seasoning blend, which are very similar. You can also use your favorite store bought blend.
That's it, my friends. I hope you enjoy my blackened fish recipe. Extra spicy for me, please! Definitely one of my favorite ways to make it. Let me know if you make it. I'd love to hear how it turned out for you. Keep it spicy!
Storage & Leftovers
Storing your Blackened Fish in an airtight container in the fridge may allow you to store the leftovers for up to 2-3 days. To maximize the storage life, make sure to refrigerate the fish promptly.

Can I cook it in a stainless steel frying pan? My stove is a glasstop electric and cast iron scratches it. I tried once 🙁
