Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. In a large bowl, toss 1 medium zucchini sliced into 1/2-inch rounds, 1 medium red bell pepper cut into 1-inch pieces, and 1 small red onion cut into wedges with 2 tbsp olive oil, 1 tsp salt, and 1/2 tsp black pepper until evenly coated.
  2. Step 2: Spread the vegetables on a large rimmed baking sheet and roast for 20 minutes, stirring halfway, until tender and slightly caramelized.
  3. Step 3: Meanwhile, place 4 cod fillets (6 oz each) in a baking dish. Drizzle 3 tbsp lemon juice and 2 tbsp olive oil over the fish. Sprinkle 3 minced garlic cloves, 2 tbsp chopped fresh thyme leaves, 1/2 tsp salt, and 1/2 tsp black pepper evenly on top.
  4. Step 4: After the vegetables have roasted 20 minutes, push them to the side of the baking sheet and place the cod fillets on the sheet. Bake everything together for an additional 12-15 minutes until the cod is opaque and flakes easily with a fork.
  5. Step 5: Serve the baked lemon-thyme cod alongside the roasted vegetables immediately.
