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


  • 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


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.
