Grilled Blackened Catfish with Cilantro-Lime Butter Recipe

Grilled blackened catfish with cilantro-lime butter is a very simple dish that will straight up transport you from your kitchen to the Caribbean (I swear). It’s a mildly spicy and limey dish that’s brought together with fresh cilantro, butter, and garlic.

My favorite part about this recipe is just how easy it is from start to finish. The catfish is simply seasoned with blackening seasoning, grilled, and topped with cilantro-lime butter.

Blackening Catfish

If you’ve never tried “blackening” fish, YOU MUST. Blackening essentially introduces worlds of spicy, smokey, cajun seasonings. I wouldn’t consider it HOT spicy, but it does have a mild degree of heat. Your typical blackening seasoning consists of dried spices such as paprika, garlic, onion, cayenne, chili, salt, black pepper, and oregano. You can make your own or used prepared blackening seasoning such as Old Bay.

Homemade Blackening Seasoning

  • 1 1/2 tablespoons paprika
  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 tablespoon ground dried thyme
  • 1 teaspoon ground black pepper
  • 1 teaspoon cayenne pepper
  • 1 teaspoon dried basil

Cilantro-Lime Compound Butter

Cilantro-lime butter is one of the most amazing toppings I’ve ever come across. It’s a recipe that came from one of my favorite cookbooks, Guy Gourmet. It’s a compound butter that combines butter, fresh cilantro, garlic, and fresh lime juice. It makes for the perfect topping for almost any type of seafood and becomes the perfect complement to the spices.

Mash all the ingredients together in room temp butter and reshape into a rolled log of butter.

If you don’t like cilantro, or you’re one of those unique individuals who think it tastes like soap (I’m truly fascinated by this), fear not—you can substitute with parsley. I don’t think it’s quite the same, but it’s still refreshing

No catfish? I would also recommend this with sea bass, mahi-mahi, or any flakey white fish such as cod or haddock.

Description

Simple blackened catfish with a delicious and tangy cilantro-lime compound butter.


Scale

Ingredients

  • 2 6-8 ounce catfish filets (only buy domestic raised) (or your favorite white fish such as cod or mahi-mahi, or sea bass)
  • 4 teaspoons (or to taste) blackening seasoning, such as Old Bay
  • olive oil (for grilling)

Cilantro-lime butter

  • 2 tablespoons butter, softened
  • 2 tablespoons cilantro, minced
  • 1 garlic clove, minced
  • 1 lime

Homemade Blackening Seasoning

  • 1 1/2 tablespoons paprika
  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 tablespoon ground dried thyme
  • 1 teaspoon ground black pepper
  • 1 teaspoon cayenne pepper
  • 1 teaspoon dried basil

Instructions

For the cilantro-lime butter

  1. Place butter in a small bowl and microwave for 5-10 second intervals to soften (or leave out on the counter). Using a fork, mash in garlic, juice from half a lime, and 1 tablespoon of minced cilantro. Spoon butter onto a small sheet of tinfoil, doing your best to reshape into a log, roll up the foil and place in refrigerator until ready to serve.

For the fish

  1. Preheat the grill to medium-high heat. Clean the grates well.
  2. Coat each side of the catfish liberally with blackening seasoning, about 1 teaspoon for each side of the filet. You can use more or less depending on preference.
  3. Lightly brush the grill with olive oil and grill filets for 5-7 minutes per side, or until white and starting to flake (The olive oil prevents the fish from sticking and breaking apart).
  4. Remove filets from the grill and top each with a slice of cilantro-lime butter, sprinkle with fresh cilantro, and serve with a lime wedge.
