4 sea bass fillets, approximately 150–180 g each
3 tablespoons olive oil, plus extra for drizzling
½ teaspoon salt, or to taste
¼ teaspoon freshly ground black pepper
1 teaspoon dried oregano
3 garlic cloves, finely minced
1 cup cherry tomatoes, halved
½ cup pitted Kalamata olives
2 tablespoons capers, drained
1 lemon, juiced and thinly sliced
2 tablespoons fresh parsley, chopped

How to Make Mediterranean Baked Sea Bass
1. Preheat the oven. Preheat your oven to 400°F (200°C). Lightly grease a medium-sized baking dish with a little olive oil.
2. Prepare the sea bass. Pat the sea bass fillets dry with paper towels to remove excess surface moisture. This helps the seasoning adhere and promotes even cooking.
3. Arrange the fish. Place the fillets in a single layer in the prepared baking dish, leaving a little space between each piece.
4. Season the fillets. Sprinkle the sea bass evenly with salt, freshly ground black pepper, and dried oregano.
5. Add the garlic. Scatter the freshly minced garlic over and around the fish.
6. Add the cherry tomatoes. Arrange the halved cherry tomatoes around the fillets, spreading them evenly across the baking dish.
7. Add the olives and capers. Scatter the Kalamata olives and drained capers among the tomatoes.
8. Add fresh lemon. Squeeze the lemon juice evenly over the fish and vegetables. Place thin lemon slices on top of each sea bass fillet.
9. Drizzle with olive oil. Pour the olive oil evenly over the fish, tomatoes, olives, and capers.
10. Bake the sea bass. Transfer the dish to the preheated oven and bake uncovered for approximately 15 minutes, or until the fish becomes opaque and flakes easily with a fork. Thicker fillets may require a few additional minutes.
11. Check for doneness. The fish should be tender and fully cooked. For food safety, sea bass should reach an internal temperature of 145°F (63°C).
12. Finish with pan juices. Remove the dish from the oven and gently spoon the softened tomatoes, olives, and warm lemon-garlic pan juices over the fish.
13. Garnish and serve. Sprinkle generously with freshly chopped parsley and finish with a light drizzle of olive oil if desired. Serve immediately.
Tips for Perfect Mediterranean Baked Sea Bass
Choose fresh sea bass. Look for fillets with firm flesh and a fresh, mild smell. Fresh or properly thawed frozen sea bass both work well.
Pat the fish dry. Removing excess moisture helps the seasonings adhere and prevents the dish from becoming unnecessarily watery.
Use good-quality olive oil. Extra virgin olive oil adds rich Mediterranean flavor and complements the tomatoes, olives, and lemon.
Don’t overcook the fish. Sea bass cooks relatively quickly and can become dry if left in the oven too long.
Use pitted olives. Pitted Kalamata olives make the finished dish easier and more enjoyable to eat.
Taste before adding extra salt. Capers and Kalamata olives are naturally salty, so you may not need much additional seasoning.
Why Cherry Tomatoes, Olives and Capers Work So Well Together
The combination of cherry tomatoes, Kalamata olives, and capers is a classic Mediterranean-inspired flavor pairing.
Cherry tomatoes become naturally sweeter as they roast, releasing juices that form the base of the sauce.
Kalamata olives provide a deep, fruity, slightly salty flavor.
Capers add a bright, tangy taste that balances the richness of the olive oil.
When combined with garlic, oregano, and fresh lemon, these ingredients create a vibrant sauce that enhances the delicate flavor of sea bass without overpowering it.
How to Make the Best Mediterranean Pan Sauce
One of the highlights of this recipe is the sauce that develops naturally during baking.
As the fish cooks, the tomatoes soften and release their juices. These combine with olive oil, lemon juice, garlic, and the natural cooking juices from the sea bass.
For a slightly thicker, more concentrated sauce, transfer the pan juices to a small saucepan after cooking and simmer gently for a few minutes.
You can also lightly crush some of the roasted cherry tomatoes with a spoon to release additional flavor.
Spoon the warm sauce generously over the fish before serving.
Can I Use Another Type of Fish?
Absolutely. This Mediterranean-style recipe works beautifully with several other mild white fish varieties.
Cod
Haddock
Halibut
Snapper
Hake
Sea bream
Choose fillets of similar thickness for even cooking.
Thinner fish may cook more quickly, while thicker fillets may require additional time in the oven.
Can I Use Frozen Sea Bass?
Yes. Frozen sea bass works well for this recipe, but it should be completely thawed before cooking.
For best results, thaw the fish overnight in the refrigerator.
Once thawed, pat the fillets dry thoroughly with paper towels before seasoning.
This helps prevent excess moisture from diluting the flavorful tomato and lemon sauce.
What to Serve with Mediterranean Baked Sea Bass
This flavorful seafood dish pairs beautifully with simple Mediterranean-inspired side dishes.
Steamed rice: Jasmine rice or basmati rice is excellent for absorbing the tomato and olive oil sauce.
Roasted potatoes: Crispy baby potatoes or lemon roasted potatoes complement the tender fish.
Couscous: Light, fluffy couscous with fresh herbs is a wonderful pairing.
Fresh vegetables: Steamed asparagus, roasted zucchini, green beans, or broccoli add freshness and color.
Crusty bread: Warm bread is perfect for soaking up the delicious pan juices.
For a complete Mediterranean dinner, serve the sea bass with roasted potatoes and a fresh green salad.
Can I Prepare This Recipe Ahead of Time?
Yes. You can prepare the vegetables and seasonings in advance.
Halve the cherry tomatoes, mince the garlic, drain the capers, and measure the olives and oregano.
Store the prepared ingredients in separate airtight containers in the refrigerator.
For the best flavor and texture, assemble and bake the fish shortly before serving.
Avoid leaving the raw fish coated in lemon juice for an extended period because the acidity can begin changing its texture.
How to Store Leftovers
Allow leftover sea bass and vegetables to cool slightly before transferring them to an airtight container.
Refrigerate promptly and consume within 2–3 days.
Store the fish with some of the tomato and olive oil sauce to help maintain moisture.
To reheat, place the sea bass in a covered baking dish and warm gently until heated through.
Avoid overheating because the delicate fish can become dry.
