Instructions

  1. Step 1: Preheat oven to 400°F. Pat dry 4 catfish fillets and rub evenly with 2 tbsp Cajun seasoning and 2 tbsp olive oil, ensuring a good coating on all sides.
  2. Step 2: Place the fillets on a baking sheet lined with parchment paper and bake for 15-18 minutes until the fish flakes easily with a fork and the edges are slightly crisp.
  3. Step 3: While fish bakes, heat 1 tbsp olive oil in a large skillet over medium heat. Add 3 minced garlic cloves and sauté for 30 seconds until fragrant.
  4. Step 4: Add 1 cup fresh corn kernels, 1 cup halved cherry tomatoes, 1 diced red bell pepper, and 1 tsp fresh thyme leaves to the skillet. Cook for 5-6 minutes, stirring occasionally, until vegetables soften and tomatoes release their juice.
  5. Step 5: Stir in 3 sliced green onions, 1 tsp salt, and 1/2 tsp black pepper; cook for an additional 2 minutes until flavors meld.
  6. Step 6: Remove catfish from oven and drizzle with 2 tbsp fresh lemon juice. Serve fillets atop the warm corn and tomato succotash.
