4.5 from 107 reviews

This Blackened Catfish recipe features flavorful catfish filets coated in a smoky, spicy rub and seared to perfection on a Blackstone griddle or cast-iron skillet.

Perfect for a quick and impressive stovetop seafood dinner.

Ingredients

Scale

Catfish and Spice Rub

  • 2 8 oz. catfish filets
  • 1 tablespoon smoked paprika
  • 1 tablespoon dark brown sugar
  • 2 teaspoons dried oregano
  • 1 teaspoon garlic powder
  • 1 teaspoon cumin
  • ½ teaspoon salt
  • ¼ teaspoon cayenne pepper

Cooking Fats

  • 2 tablespoons canola oil
  • 1 tablespoon unsalted butter

Instructions

  1. Prepare the Spice Rub and Coat Catfish: In a shallow dish, combine the smoked paprika, dark brown sugar, dried oregano, garlic powder, cumin, salt, and cayenne pepper using a fork to mix thoroughly. Pat the catfish filets dry with a paper towel to remove any excess moisture. Dredge each filet evenly in the spice rub, ensuring all sides are coated well. Shake off any excess seasoning to prevent burning.
  2. Preheat and Prepare Cooking Surface: Heat your Blackstone griddle or a cast-iron skillet over medium-high heat. Once hot, pour in the canola oil and spread it evenly across the surface using a long-handled spatula. Add the unsalted butter next, spreading it around as it melts until it becomes foamy, which indicates it’s ready for cooking.
  3. Cook the Catfish Filets: Place the coated catfish filets on the hot griddle or skillet. Cook them undisturbed for about 3 minutes on the first side to develop a blackened crust. Then carefully flip the filets over and cook for an additional 3 minutes. The fish should be nicely browned on both sides and flake easily when tested with a fork, indicating it’s fully cooked.

Notes

  • Patting the catfish dry before applying the rub helps the spices adhere better and promotes a better crust formation.
  • Adjust the cayenne pepper quantity to make the dish milder or spicier according to your preference.
  • Use a cast-iron skillet if you don’t have a Blackstone griddle; it works equally well for this recipe.
  • Do not overcrowd the pan; cook in batches if necessary to maintain temperature and ensure even cooking.
  • Serve immediately for the best texture and flavor, perhaps with fresh lemon wedges or a side salad.
