Introduction
Blackened catfish is a flavorful, spicy dish that’s perfect for a quick weeknight dinner or a casual gathering. Using a Blackstone griddle or a cast-iron skillet, this recipe creates a crispy, smoky crust while keeping the fish tender inside.

Ingredients
- 2 8 oz. catfish filets
- 2 tablespoons canola oil
- 1 tablespoon unsalted butter
- 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
Instructions
- Step 1: In a shallow dish, combine smoked paprika, dark brown sugar, dried oregano, garlic powder, cumin, salt, and cayenne pepper using a fork. Pat the catfish filets dry with a paper towel, then coat them evenly with the spice mixture, shaking off any excess.
- Step 2: Preheat your Blackstone griddle or cast-iron skillet to medium-high heat. Add the canola oil and spread it evenly with a spatula. Then add the butter and swirl it until melted and foamy.
- Step 3: Place the catfish filets on the hot cooking surface. Cook for about 3 minutes on each side until the fish develops a crisp, browned crust and flakes easily with a fork.
Tips & Variations

- Swap catfish for other firm white fish like tilapia or snapper if preferred.

FAQs
Can I use this recipe on a regular frying pan?

Ingredients
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
- 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.
- 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.
- 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.
