Follow these simple steps to create the perfect Spicy Cajun Catfish:

1. Prepare the Catfish: Rinse the catfish fillets under cold water and pat them dry with paper towels. Place them on a large plate or baking sheet.
2. Mix the Seasonings: In a small bowl, combine the Cajun seasoning, paprika, garlic powder, onion powder, thyme, oregano, salt, black pepper, and cayenne pepper. Mix until well blended.
3. Season the Fillets: Sprinkle the seasoning mixture evenly over both sides of the catfish fillets. Gently press the seasoning into the fish to ensure it adheres well.
4. Preheat the Pan: In a large skillet, heat the olive oil and butter over medium-high heat. Allow the butter to melt and the pan to get hot.
5. Cook the Catfish: Place the seasoned catfish fillets in the hot skillet. Cook for about 4-5 minutes on each side, or until the fish is cooked through and flakes easily with a fork. The outside should be golden brown and slightly crispy.
6. Add Lemon Juice: In the last minute of cooking, drizzle the lemon juice over the catfish fillets. This will add a bright, zesty flavor to the dish.
7. Garnish and Serve: Remove the catfish from the skillet and place it on a serving platter. Garnish with chopped fresh parsley and serve with lemon wedges on the side.
