    Combine 2 tbsp paprika, 1 tsp cayenne pepper, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp dried thyme, 1/2 tsp dried oregano, 1 tsp salt, and 1/2 tsp black pepper in a shallow bowl to create the blackening spice blend.

Questions

What internal temperature should Blackened Catfish reach?

For Blackened Catfish, the target internal temperature is 145 F (about 65 C), given in step 7. A probe thermometer removes the guesswork.

Why pat it dry first in Blackened Catfish?

Step 2 reads: "Pat 2 lbs patted dry catfish fillets (6-8 oz each) dry with paper towels." Surface water has to boil off before anything can brown. Drying at step 2 means the food sears in the first minute instead of steaming.

Can I use a different white fish instead of the catfish in Blackened Catfish?

Yes. Any firm white fish of similar thickness works: cod, haddock, pollock and halibut are interchangeable here. Timing follows thickness, not species. As written, the entry for Blackened Catfish uses 2 lbs catfish fillets (6-8 oz each), patted dry.

Is Blackened Catfish spicy?

Moderately. The heat in Blackened Catfish comes from 1 tsp cayenne pepper. For a milder plate, halve the cayenne; nothing else in the method changes. For more, add it at the table rather than in the pot, so everyone sets their own level.

Can I make Blackened Catfish dairy-free?

Yes. The dairy in Blackened Catfish is 4 tbsp butter. Swap the butter for olive oil where it melts, or a plant-based block butter where it is creamed. The richness shifts slightly, but the method does not change.

Does Blackened Catfish contain fish?

Yes: 2 lbs catfish fillets (6-8 oz each), patted dry. The full allergen list for this entry is dairy and fish. Packaged ingredients vary by brand, so check labels if the allergy is serious.
