Ingredients for Sheet Pan Mediterranean Baked Cod with Roasted Pepper and Olive Medley

Instructions

Preheat oven to 425°F (220°C). Line a large sheet pan with parchment paper or lightly grease it.
In a large bowl, toss together sliced red and yellow bell peppers, red onion wedges, Kalamata olives, and minced garlic.
Drizzle 2 tablespoons olive oil over the vegetables. Season with dried oregano, smoked paprika, salt, pepper, and crushed red pepper flakes, if using. Toss to coat evenly.
Spread the vegetable mixture in a single layer on the prepared sheet pan.
Roast vegetables for 15 minutes in the preheated oven.
Meanwhile, pat cod fillets dry with paper towels. Combine remaining 1 tablespoon olive oil with lemon juice, lemon zest, and a pinch of salt and pepper in a small bowl.
After 15 minutes, remove the sheet pan and nestle the cod fillets among the vegetables.
Brush each cod fillet with the lemon-olive oil mixture.
Return the sheet pan to the oven and roast all together for an additional 10 minutes, or until cod is opaque and flakes easily.
Remove from oven, sprinkle with fresh chopped parsley, and serve immediately with extra lemon wedges.
