Ingredients

Instructions

  1. Step 1: Preheat grill to medium-high heat (about 400°F). In a bowl, whisk together 3 tbsp olive oil, 2 tbsp lemon juice, 3 minced garlic cloves, 1 tsp smoked paprika, 1 tsp salt, and 1/2 tsp black pepper. Coat 4 catfish fillets with this marinade and let rest for 10 minutes.
  2. Step 2: Meanwhile, preheat oven to 425°F. Toss 1 sliced zucchini, 1 chopped red bell pepper, 1 sliced yellow squash, and 1 small cut red onion with 1 tbsp olive oil, 1 tbsp chopped fresh thyme, and a pinch of salt and pepper. Spread on a baking sheet and roast for 20 minutes until tender and slightly caramelized.
  3. Step 3: Grill catfish fillets for 4-5 minutes per side until the flesh is opaque and flakes easily with a fork. Serve the grilled catfish alongside the roasted vegetables for a fresh, river-inspired meal.
