Instructions

1. Step 1: Preheat a grill or grill pan to medium-high heat (about 400°F). Brush 4 catfish fillets with 2 tbsp olive oil and sprinkle evenly with 2 tbsp Cajun seasoning, 1/2 tsp salt, and 1/4 tsp black pepper.
2. Step 2: Place the catfish on the grill and cook for 4-5 minutes per side, until opaque and flaky, with grill marks and a slight char around the edges.
3. Step 3: While the fish cooks, char 1 1/2 cups fresh corn kernels in a dry skillet over medium-high heat for 5-7 minutes, stirring occasionally, until kernels are browned and fragrant.
4. Step 4: Combine the charred corn with 1/2 cup diced red bell pepper, 1/4 cup finely chopped red onion, 2 tbsp chopped fresh cilantro, 2 tbsp lime juice, 1/2 tsp salt, 1/4 tsp black pepper, and 1 tbsp olive oil in a bowl. Stir to combine and let flavors meld for 5 minutes.
5. Step 5: Serve the grilled Cajun-spiced catfish topped with a generous spoonful of the charred corn relish alongside your favorite sides.
