Ingredients

Instructions

  1. Step 1: Pat dry 4 catfish fillets and season both sides evenly with 2 tbsp Cajun seasoning, pressing gently to adhere.
  2. Step 2: Heat 3 tbsp olive oil in a large skillet over medium-high heat. When shimmering, add the fillets and cook for 4 minutes per side until the edges are golden and fish flakes easily; transfer to a warm plate.
  3. Step 3: In the same skillet, reduce heat to medium, add 4 tbsp butter and 3 minced garlic cloves; sauté for 1 minute until fragrant and butter begins to brown slightly.
  4. Step 4: Stir in 2 tbsp fresh lime juice and 1/4 cup chopped cilantro, then spoon the Cajun butter sauce over the cooked catfish fillets.
  5. Step 5: Meanwhile, preheat a separate pan over medium-high heat. Add 1 cup corn kernels, 1/2 diced red bell pepper, 1/4 cup diced red onion, and 1 minced jalapeño; sauté for 5 minutes until vegetables are tender and slightly charred.
  6. Step 6: Season the roasted corn salsa with salt and black pepper to taste, then serve atop or alongside the catfish for a bright, smoky contrast.

How do I store leftover Pan-Seared Catfish with Cajun Butter and Roasted Corn Salsa?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Pan-Seared Catfish with Cajun Butter and Roasted Corn Salsa?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut).

How do I scale Pan-Seared Catfish with Cajun Butter and Roasted Corn Salsa 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.
