Cooking blackened redfish in a hot skillet couldn't be easier. Delicious, flaky gulf-coast caught redfish seasoned with a combination of tasty spices then flash cooking over very high heat with melted butter is Cajun perfection.

What makes this recipe so yummy

  • Chef Paul Prudhomme came up with this recipe decades ago and it hasn't gone away. It was so popular when it first came out that the Louisiana Wildlife and Fisheries had to change the limits on fishing for redfish.
  • There's not a huge shopping list to make this dish - it's simple to make- all you will need to worry about is sides.
  • It's healthier than deep frying. Other than the little butter and olive oil, you're not consuming a bunch of fried crumbs.
  • This recipe gives a delicious seasoned crust on the outside but firm white flaky fish inside. The blackening technique is very famous.

Recipe walkthrough: Instructions

This is an overview of the recipe steps. For more detailed instructions visit the recipe card at the bottom of this post.

A plate full of redfish fillets, being patted dry with some paper towel.
Step 1: Wash and pat dry the redfish fillets with paper towels.
Butter being brushed onto some redfish fillets.
Step 2: Melt the butter in a small bowl and brush the fillets.
Redfish fillets seasoned liberally.
Step 3: Season liberally with the blackening spice.

Step 4: Pan fry in a large cast-iron skillet that has been pre-heated with olive oil. Cook both sides and depending on the fillet's thickness, the side of the fillets too. Serve with a lemon wedge or lime juice.

Hint: You could say my amount of seasoning (in the images) has more of a bronze look. I don't use as much as some people. If you like a spicier redfish, you can totally coat the redfish fillets and make it totally black. It will increase the heat.

Recipe variations and substitute ideas

  • Homemade Blackening Spice - instead of using the store-bought seasoning blend you can make it at home. Here's the ratios:
    • 2 Tablespoons Smoked Paprika
    • 1 Tablespoon Cayenne Pepper
    • 1 Tablespoon Onion Powder
    • 2 teaspoons Garlic Powder
    • 1 teaspoon Black Pepper
    • 1 teaspoon Salt
    • ½ teaspoon dried Thyme Leaves
    • ½ teaspoon dried Oregano Leaves
    • ½ teaspoon dried Basil Leaves
  • White Pepper -this can be added too for a more smoky flavor.
  • Sweet Paprika - if you're making your own spice mix.
  • Red Snapper Fillets - you could use a number of different types of fish.
  • Green Onion - sprinkle with some chopped, on top. As well as some purple cabbage for a blast of color?

A cast iron skillet is my favorite way to cook blackened redfish. You can get it really hot and it's an even heat all around.

How to store leftovers

Should you have leftovers, I recommend storing in an airtight container in the refrigerator for up to 3 days. Give a quick heat up in the microwave to not overcook when reheating.

Mel's kitchen notes

If you are preparing the redfish (red drum) yourself you'll want to cut away as much of the bloodline as possible. This can add quite a strong flavor that a lot of people don't like.

Frequently asked questions: FAQs

What does redfish taste like?

Redfish is a salt water fish that has a delicious mild flavor with a firm texture meat. The bigger (older) redfish tend to have a stronger, more robust flavor.

Is blackened redfish spicy?

It can be, depending how much of the spice you use. As you can see in my images, I kept it to more of a bronze color, to not overdo the spices (for the kiddos), but you can get real heavy-handed and have a very spicy piece of fish.

Equipment

  • Walfos Silicone Basting Pastry Brush
  • 10 Inch Pre-Seasoned Cast Iron Skillet

Ingredients

  • 2 teaspoons Olive Oil
  • 3 Pounds Redfish Fillets
  • ½ Cup Unsalted Butter unsalted and melted
  • ¼ Cup Blackening Seasoning

Instructions

  • Add the olive oil to a heavy bottomed skillet - like a cast iron skillet. Add medium-high heat.
    2 teaspoons Olive Oil
  • Take the redfish fillet and brush all over the melted butter.
    3 Pounds Redfish Fillets, ½ Cup Unsalted Butter
  • Take the seasoning and sprinkle liberally all over. Pat it all over the fish.
    ¼ Cup Blackening Seasoning
  • Once the skillet looks like it's smoking, as it's so hot, add the redfish fillets. Leave to cook for about 3 minutes, then carefully flip the redfish over and cook the other side another 3 minutes.
  • Remove and serve.

Notes

Depending on how spicy/seasoned you like your redfish will determine how much seasoning you should use. I did not use as much as some people do, making the redfish have more of a bronze color to it. I prefer it like this as my kids can't eat it too spicy.
