Preparation Steps:

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Prepare a baking sheet by lining it with parchment paper. This will prevent the fish and shrimp from sticking and make cleanup easier.

Step 2: Prepare the Seafood

Take your catfish fillets and shrimp and pat them dry using paper towels. This step is crucial as it ensures that the seasoning sticks properly to the surface, and it also helps create a better texture during baking. Once dry, brush both the catfish and shrimp generously with olive oil.

Step 3: Season the Fish and Shrimp

In a small bowl, mix together the Cajun seasoning, paprika, garlic powder, onion powder, salt, and pepper. This blend of spices brings the bold, spicy flavor characteristic of Cajun cuisine. Rub this spice mixture evenly over the catfish fillets and shrimp, ensuring that every piece is well coated with the aromatic flavors.

Step 4: Bake the Catfish and Shrimp

Place the seasoned catfish fillets and shrimp on the lined baking sheet. Make sure they are spread out evenly to allow for proper baking. Transfer the sheet into the preheated oven and bake for 15-20 minutes. You will know the catfish is done when it flakes easily with a fork, and the shrimp should be pink and opaque, indicating they are cooked through.

Step 5: Prepare the Zesty Lemon Butter

While your catfish and shrimp are baking, it’s time to make the zesty lemon butter sauce. In a small saucepan or microwave-safe bowl, melt the butter. Once melted, add the freshly squeezed lemon juice and chopped parsley, stirring to combine. This butter sauce will enhance the seafood’s flavors with a tangy, herby kick.

Step 6: Serve with Lemon Butter

Once the catfish and shrimp are fully baked, remove them from the oven. Drizzle the warm, zesty lemon butter sauce generously over the top of the seafood. This buttery, citrusy finish elevates the dish and perfectly complements the spiciness of the Cajun seasoning.

Step 7: Serve

Serve the dish hot, accompanied by lemon wedges on the side for an extra pop of freshness. The citrus from the lemon enhances the overall flavor and adds brightness to each bite.
