  • Prep Time: 10 mins
  • Cook Time: 10 mins
  • Total Time: 20 mins
  • Yield: 2 1x



  • 2 6-8 ounce catfish filets (or your favorite white fish)
  • 4 teaspoons (or to taste) blackening seasoning, such as Old Bay
  • 2 tablespoons butter
  • 2 tablespoons cilantro, minced
  • 1 garlic clove, minced
  • 1 lime
  • olive oil (for grilling)


  1. Preheat the grill to medium-high heat.
  2. For the cilantro-lime butter: Place butter in a small bowl and microwave for 10-15 seconds to soften. 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.
  3. 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.
  4. 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).
  5. 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.
