Instructions

  1. Step 1: Pat dry 4 catfish fillets and rub 2 tbsp Cajun seasoning evenly over both sides. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering.
  2. Step 2: Place the seasoned catfish fillets in the skillet and cook for 4-5 minutes on each side until the exterior is golden brown and the fish flakes easily with a fork. Remove and keep warm.
  3. Step 3: In a separate skillet, heat 1 tbsp olive oil over medium heat. Add 1 cup fresh corn kernels, 1 diced red bell pepper, 1 diced green bell pepper, and 1/4 cup finely chopped red onion. Sauté for 5-6 minutes until vegetables are tender and slightly caramelized.
  4. Step 4: Remove from heat and stir in 2 tbsp chopped fresh cilantro and 1 tbsp fresh lime juice. Season with salt and black pepper to taste.
  5. Step 5: Serve the pan-seared catfish topped with the warm Cajun-spiced corn relish.

Frequently asked questions

How long does Pan-Seared Catfish with Cajun-Spiced Corn Relish take to make?

Total time is about 25 minutes (10 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Pan-Seared Catfish with Cajun-Spiced Corn Relish?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days. Freeze cooked fish (without fresh garnishes) for up to 3 months; thaw overnight in the fridge and reheat gently at 275°F until just warmed through to preserve texture.

Can I substitute ingredients in Pan-Seared Catfish with Cajun-Spiced Corn Relish?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Pan-Seared Catfish with Cajun-Spiced Corn Relish for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
