Ingredients You’ll Need

For the Fish:

2 tbsp extra virgin olive oil
2 garlic cloves, minced
Juice of 1 lemon
Zest of 1 lemon
1 tsp dried oregano (or 1 tbsp fresh oregano)

¼ tsp freshly ground black pepper
Optional: ½ tsp paprika or a pinch of crushed red pepper

Garnish (Optional):

How to Make Greek Baked Fish

1. Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a baking dish with olive oil or line it with parchment paper.

2. Prepare the Marinade

In a small bowl, whisk together olive oil, garlic, lemon juice and zest, oregano, salt, and pepper.

3. Marinate the Fish

Pat the fish fillets dry. Place them in the baking dish. Pour the marinade evenly over the fillets, turning them gently to coat both sides. Let it marinate for 10–15 minutes if time allows.

4. Bake the Fish

Bake uncovered for 15–18 minutes, depending on the thickness of your fillets. The fish should flake easily with a fork and be opaque in the center.

5. Serve

Garnish with freshly chopped parsley and extra lemon wedges. Serve warm with your favourite Mediterranean side dishes.

Tips for Success

Use fresh lemon juice – It makes a huge difference in flavour.
Don’t overbake – Fish cooks quickly; check at 15 minutes.
Oregano is key – Dried Greek oregano adds bold, authentic flavour.
Fish options – Choose firm, mild-flavoured white fish like cod, snapper, or halibut.

Frequently Asked Questions

Which fish suits Greek baked fish?

Sea bass, sea bream, cod or any firm white fish works. Whole fish and thick fillets stay moist when baked with lemon and olive oil.

Can I use dried oregano?

Yes, dried Greek oregano is traditional and has a stronger flavour than fresh, so use a little less if you swap.

How do I stop the fish drying out?

Use enough olive oil, do not overbake, and take the fish out as soon as it flakes. Resting for a few minutes also helps.
