Mediterranean Baked Fish
Description
Mediterranean Baked Fish is a fresh, flavourful, and wonderfully simple one-pan dinner made with tender white fish, juicy cherry tomatoes, fresh herbs, lemon, garlic, olive oil, and a touch of spice. The fish is baked gently until flaky and tender while the tomatoes soften and release their juices, creating a light and naturally delicious sauce.
This recipe captures everything people love about Mediterranean-style cooking: fresh ingredients, bright citrus, aromatic herbs, heart-healthy olive oil, and plenty of flavour without relying on heavy sauces.
It is perfect for busy weeknights because it requires minimal preparation and cooks quickly. At the same time, the colourful presentation makes it elegant enough for a family gathering or dinner with guests.
You can prepare this dish with cod, haddock, halibut, sea bass, tilapia, or another firm white fish. The lemon provides brightness, the tomatoes add sweetness, garlic brings savoury depth, and chilli flakes provide just enough heat to make every bite exciting.
Serve it with a simple green salad, roasted vegetables, quinoa, couscous, brown rice, or warm whole-grain bread to make a complete Mediterranean-inspired meal.

Ingredients
For the Fish
- 4 white fish fillets, approximately 5–6 ounces each
- 2 tablespoons extra-virgin olive oil
- 1 teaspoon dried oregano
- 1/2 teaspoon paprika
- 1/4 teaspoon crushed red pepper flakes, or more to taste
- 3 cloves of garlic, minced
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the Mediterranean Topping
- 1 1/2 cups cherry tomatoes, halved
- 1 small red onion, thinly sliced
- 1 lemon, thinly sliced
- 2 tablespoons fresh lemon juice
- 1/4 cup chopped fresh parsley
- 2 tablespoons fresh dill, chopped
- 1 tablespoon extra-virgin olive oil
- Optional: 1/3 cup Kalamata olives
- Optional: 1 tablespoon capers
Instructions
1. Preheat the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a large baking dish with olive oil. Choose a dish large enough to hold the fish fillets in a single layer without crowding them.
2. Prepare the Fish
Pat the fish fillets dry with paper towels. Removing excess moisture helps the seasoning stick and allows the fish to roast rather than steam.
Place the fish fillets in the prepared baking dish.
Drizzle the fish with 2 tablespoons of olive oil.
Sprinkle evenly with oregano, paprika, red pepper flakes, salt, and black pepper.
Add the minced garlic over and around the fish.
Gently rub the seasoning over the surface of each fillet so the flavours are evenly distributed.
3. Add the Vegetables
Scatter the halved cherry tomatoes and sliced red onion around the fish.
If you’re using Kalamata olives or capers, add them now.
Arrange several thin lemon slices around and between the fish fillets.
Drizzle the vegetables with another tablespoon of olive oil.
The tomatoes will release their juices as they bake, combining with the olive oil, garlic, and lemon to create a flavourful sauce.
4. Add Lemon Juice
Drizzle the fresh lemon juice over the fish and vegetables.
Fresh lemon juice gives the dish a bright, citrussy flavour that balances the richness of the olive oil and complements the delicate fish.
5. Bake
Place the baking dish in the preheated oven.
Bake for approximately 15–20 minutes, depending on the thickness of the fish fillets.
Thin fillets may cook in as little as 12–15 minutes, while thicker pieces may require closer to 20 minutes.
The fish is ready when it becomes opaque and flakes easily when gently pressed with a fork.
For the most accurate result, check the thickest part of the fish with a food thermometer. Fish is generally considered safely cooked at 145°F (63°C).
Avoid overcooking because white fish can become dry when left in the oven too long.
6. Finish with Fresh Herbs
Remove the fish from the oven and allow it to rest for 2–3 minutes.
Sprinkle generously with freshly chopped parsley and dill.
For an extra burst of citrus, squeeze a little additional lemon juice over each serving.
Spoon some of the roasted tomatoes and onions over the fish along with the flavourful juices from the bottom of the baking dish.
7. Serve
Serve the baked fish immediately while hot.
The roasted tomatoes, lemon, garlic, and herbs create a naturally flavourful sauce that can be spooned over the fish.
Pair it with your favourite Mediterranean side dish for a satisfying and balanced meal.
Notes
Choose firm white fish: Cod, haddock, halibut, sea bass, and similar fish work particularly well. Thicker fillets are easier to bake without drying out.
Use fresh lemon: Fresh lemon juice provides a much brighter flavour than bottled juice, especially in a simple recipe like this.
Don’t overcook the fish: fish cooks quickly. Start checking it around the 12–15 minute mark if your fillets are thin.
Keep the tomatoes: Cherry tomatoes are particularly useful because they become juicy and slightly caramelised without completely falling apart.
Adjust the spice: Red pepper flakes provide gentle heat. Reduce them for a mild dish or increase them if you enjoy spicy food.
Don’t overcrowd the baking dish: Give the fish enough room so heat can circulate evenly.
Use fresh herbs at the end: Parsley and dill taste fresher and more vibrant when added after baking rather than cooked for the entire time.
Tips for the Best Mediterranean Baked Fish
1. Pat the Fish Dry
Before seasoning, use paper towels to gently dry the fish. This helps the olive oil and seasonings adhere to the surface.
2. Choose Similar-Sized Fillets
If possible, use fish pieces that are similar in thickness. This allows them to finish cooking at approximately the same time.
3. Don’t Skip the Garlic
Garlic is one of the key ingredients that gives the dish its Mediterranean character. Fresh minced garlic provides a stronger and more aromatic flavour than garlic powder.
4. Use High-Quality Olive Oil
Since olive oil is an important part of the sauce, using a good-quality extra-virgin olive oil can noticeably improve the flavour.
5. Add the Herbs at the Right Time
Dill and parsley are delicate herbs. Adding them after baking preserves their fresh flavour and bright colour.
6. Watch the Cooking Time
The exact cooking time depends on the type and thickness of your fish. Start checking early rather than relying only on the recipe’s estimated time.
7. Let the Tomatoes Make the Sauce
There is no need for a heavy cream or complicated sauce. The cherry tomatoes release their juices while baking, blending naturally with olive oil, garlic, lemon, and herbs.
Serving Suggestions
Mediterranean Baked Fish works beautifully with a variety of sides.
For a light meal, serve it with a crisp cucumber, tomato, and parsley salad.
For something more filling, serve it with quinoa, couscous, brown rice, or roasted potatoes.
Roasted zucchini, asparagus, broccoli, green beans, or bell peppers also pair wonderfully with the fish.
A simple lemony arugula salad can add a peppery freshness that complements the delicate fish.
You can also serve the dish with warm whole-grain bread. The bread is excellent for soaking up the roasted tomato, garlic, lemon, and olive oil juices.
For a lower-carbohydrate meal, serve the fish with cauliflower rice, sautéed spinach, zucchini noodles, or a large green salad.
Variations
Mediterranean Olive Fish
Add Kalamata olives and capers before baking. Their briny flavour pairs beautifully with lemon and tomatoes.
Greek-Style Baked Fish
Add oregano, Kalamata olives, red onion, parsley, and a small amount of crumbled feta after baking.
Garlic Butter Version
Replace part of the olive oil with a small amount of melted butter for a richer flavour.
Spicy Baked Fish
Increase the crushed red pepper flakes and add a pinch of cayenne pepper for additional heat.
Herb-Lover’s Version
Add fresh basil, dill, parsley, and oregano for a more intensely herbaceous dish.
Mediterranean Vegetable Version
Add sliced zucchini, bell peppers, spinach, or mushrooms around the fish before baking.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 2–3 days.
To reheat, place the fish in a covered baking dish and warm gently in a 300–325°F (150–165°C) oven until heated through.
Avoid reheating at very high temperatures because this can dry out the fish.
Leftover fish can also be flaked and added to salads, wraps, grain bowls, or sandwiches.

The combination of protein, vegetables, and healthy fats creates a balanced meal that can be filling without feeling overly heavy.
Frequently Asked Questions
What type of fish is best for this recipe?
Cod is an excellent choice because it is mild, flaky, and widely available. Haddock, halibut, sea bass, tilapia, and other firm white fish can also work well.
Can I use frozen fish?
Yes. Thaw the fish completely in the refrigerator and pat it very dry before seasoning and baking.
Can I use salmon instead?
Absolutely. Salmon works beautifully with lemon, garlic, tomatoes, herbs, and olive oil. Because salmon is usually thicker and richer than white fish, adjust the cooking time according to the size of the fillets.
Can I make this recipe without red pepper flakes?
Yes. Simply leave them out for a completely mild version.
Can I add feta cheese?
Yes. Crumbled feta added after baking gives the dish a delicious Greek-inspired flavour.
How do I know when the fish is done?
The fish should be opaque and flake easily with a fork. For the most reliable result, check the thickest part with a food thermometer and aim for 145°F (63°C).
Why did my fish become dry?
The most common reason is overcooking. Fish cooks quickly, especially thin fillets. Begin checking early and remove it from the oven as soon as it is cooked through.
Can I prepare the ingredients ahead of time?
Yes. You can slice the onion, halve the tomatoes, chop the herbs, and prepare the seasoning several hours ahead. Keep everything refrigerated until you’re ready to assemble and bake.
Can I make this in a skillet?
Yes. Use an oven-safe skillet and arrange the fish and vegetables in a single layer before transferring it to the oven.
Can I add potatoes?
Yes, but potatoes require more time to cook than fish. Cut them into small pieces and roast them until nearly tender before adding the fish.
Can I make this recipe dairy-free?
Yes. The basic recipe is naturally dairy-free as long as you don’t add optional feta or butter.
Is this recipe good for meal prep?
Yes. Store individual portions in airtight containers with vegetables and their juices. Refrigerate and consume within 2–3 days for the best quality.
