Ingredients

  • 2 lbs cod fillets, either one large or 4-6 individual fillets
  • tsp Kosher salt, divided
  • ¼ tsp Freshly ground black pepper
  • ¼ cup extra virgin olive oil, divided
  • 1 medium lemon, zested, plus another if you want to slice them into rounds
  • 1 pint cherry or grape tomatoes, halved, about 1½-2 cups
  • cups Kalamata olives, or Castelvetrano olives, or a mix of the two, pitted and halved
  • ½ medium red onion, thinly sliced into half moons
  • 3 cloves garlic, thinly sliced
  • 1 Tbsp red wine vinegar
  • 1 tsp dried oregano
  • Fresh parsley, for serving
  • Lemon wedges, for serving, optional

Instructions

  • Season the cod fillet. Preheat an oven to 425°F (218°C). Pat the fish dry with paper towels, then season on both sides with 1 tsp Kosher salt and ¼ tsp freshly ground black pepper. Place the seasoned fillet inside a baking dish, then drizzle with 2 Tbsp of olive oil. Sprinkle on the reserved lemon zest.
  • Make the tomato and olive relish. In a medium bowl, combine halved tomatoes, olives, thinly sliced red onion, and garlic cloves. Drizzle with remaining 2 Tbsp olive oil and 1 Tbsp red wine vinegar, then season with 1 tsp dried oregano and ½ tsp Kosher salt. Toss well, then pour on top of the cod.
  • Bake the cod. Bake the fish for 15-18 minutes, or until the internal temperature reaches around 140°F (60°C) -- this temperature will continue to rise as it rests. Serve immediately with fresh parsley and lemon wedges on the side.

Notes

  • Leftovers: Cooked seafood has a shorter shelf life than meat or poultry. We recommend enjoying within 3 days. Store leftovers in an airtight container in the fridge.
  • Cod: If you can't find cod, try using haddock, hake, sea bass, or pollock.
