Preheat your oven to 400°F (200°C) if baking.

Rinse the cod fillets under cold water and pat dry with paper towels.

Place the cod fillets in a lightly greased baking dish and drizzle with olive oil.

In a small bowl, combine minced garlic, lemon zest, oregano, paprika, salt, and pepper to create a marinade.

Spread the marinade over the cod fillets and squeeze fresh lemon juice on top. Allow to marinate for at least 15 minutes.

For baking, place the dish in the preheated oven and bake for 12-15 minutes until the cod flakes easily with a fork.

For grilling, preheat the grill to medium-high heat, oil the grates, and grill the fillets for about 4-5 minutes on each side.

For pan-searing, heat olive oil in a skillet over medium heat and cook the fillets for about 3-4 minutes on each side until golden brown.

Check that the internal temperature reaches 145°F (63°C) for safe consumption.

Let the cod rest for a few minutes before serving. Garnish with fresh parsley.
