How to Make Easy Mediterranean Baked Fish

1. Prepare the oven

Preheat the oven to 400°F. Lightly grease or line a baking dish.

2. Make the herb marinade

Add the thyme, rosemary, oregano, parsley, optional basil, garlic, lemon zest, lemon juice, sweet chili sauce, salt, black pepper, and olive oil to a bowl.

Mix everything together well.

3. Marinate the fish

Generously rub the marinade over both sides of the fish fillets.

Set the fish aside and save ½ tablespoon of the marinade.

4. Coat the vegetables

Add the cherry tomatoes, pitted olives, diced onion, and diced zucchini to the remaining marinade.

Mix with a spoon until the vegetables are well coated.

5. Assemble the baking dish

Pour the vegetables into the prepared baking dish.

Place the fish fillets on top of the vegetables.

Scrape any remaining marinade from the bowl and pour it over the fish.

6. Bake

Place the baking dish on the middle rack of the oven and bake at 400°F for 15 minutes.

The exact baking time depends on the thickness of the fish fillets.

The fish is ready when it is flaky or reaches an internal temperature of 145°F.

7. Rest and serve

Remove the fish from the oven and let it rest for about 5 minutes before serving.

Important Cooking Tips

• Use the middle oven rack: The recipe specifically calls for baking the dish on the middle rack.
• Coat both sides of the fish: Rub the marinade generously over both sides before setting the fillets aside.
• Don’t discard the remaining marinade: The remaining marinade is used to coat the vegetables and is then poured over the fish.
• Check the fish rather than relying only on time: Fillet thickness affects cooking time. The recipe recommends cooking until flaky or until the fish reaches 145°F internally.
• Let the fish rest: Allow about 5 minutes of resting time after removing it from the oven.
