Instructions
- Step 1: Preheat your oven to 425°F. Place 2 large poblano peppers on a baking sheet and roast for 20 minutes, turning halfway, until skins are blackened and blistered. Remove and place in a covered bowl for 10 minutes to steam.
- Step 2: Peel the skins off the roasted poblano peppers, remove seeds, and chop finely. In a medium skillet, heat 1 tbsp olive oil over medium heat. Add 3 minced garlic cloves and 1/2 chopped yellow onion, sautéing for 3-4 minutes until softened and fragrant.
- Step 3: Add the chopped poblano peppers, 1/2 cup heavy cream, 1 tbsp fresh lime juice, 1 tsp kosher salt, and 1/2 tsp black pepper to the skillet. Simmer for 5 minutes until the sauce thickens slightly, then remove from heat and keep warm.
- Step 4: Pat dry 4 catfish fillets and evenly coat both sides with 2 tbsp Cajun seasoning. Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add the fillets and sear for 4 minutes on each side until cooked through and edges are crisp.
- Step 5: Plate the catfish fillets and spoon the roasted poblano pepper sauce generously over the top before serving.
