Instructions

1. Step 1: Preheat your oven to 425°F. In a small bowl, combine 1 tsp smoked paprika, 1/2 tsp cayenne pepper, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp dried oregano, 1 tsp salt, and 1/2 tsp black pepper to create the Cajun spice blend.
2. Step 2: Place 4 catfish fillets on a large sheet pan. Drizzle 2 tbsp olive oil evenly over the fillets and rub the Cajun spice blend all over the fish, ensuring even coverage.
3. Step 3: In a separate bowl, toss 1 cup sweet corn kernels, 1 diced red bell pepper, and 1 diced yellow bell pepper with 1 tbsp olive oil and a pinch of salt and pepper. Spread the vegetables around the fish on the sheet pan.
4. Step 4: Roast in the preheated oven for 12-15 minutes, or until the catfish flakes easily with a fork and the vegetables are tender and slightly caramelized.
5. Step 5: Remove from oven and serve immediately with 4 lemon wedges to squeeze over the fish for a bright finish.
