Ingredients
Main Ingredients:
- White fish fillets (6 oz each) – cod, sea bass, snapper, or halibut work beautifully
- Cherry tomatoes, halved
- Kalamata olives, pitted and halved
- Red onion, thinly sliced
- Garlic, minced
- Capers, drained
- Lemon, sliced into rounds
- Extra virgin olive oil
Fresh Herb Blend:
- Fresh parsley, chopped
- Fresh dill, chopped
- Fresh oregano (or ½ teaspoon dried)
- Fresh thyme leaves
- Salt and freshly ground black pepper to taste
Smart Substitutions:
For those with dietary restrictions, this recipe adapts easily. Swap regular fish for any firm white fish – even frozen fish fillets work when properly thawed. Don't have fresh herbs? Use half the amount of dried herbs instead. Skip the capers if you're not a fan, or replace kalamata olives with green olives for a milder flavor.
The red onion adds a lovely sweet-sharp bite, but yellow onions work too. For extra richness, add a handful of crumbled feta cheese during the last 5 minutes of baking.

Instructions
Prepping Your Mediterranean Base
- Preheat your oven to 400°F (200°C) and position the rack in the center.
- Line a large sheet pan with parchment paper – this makes cleanup a breeze and prevents sticking.
- In a large bowl, combine the halved cherry tomatoes, sliced red onion, minced garlic, and capers.
- Drizzle with 2 tablespoons of olive oil and season with salt and pepper.
- Toss everything together until the vegetables are well-coated and glistening.
This mixture becomes the flavorful foundation that infuses the fish with Mediterranean goodness as it bakes.
Preparing the Fish Fillets
- Pat your fish fillets completely dry with paper towels – this step is crucial for achieving that perfect golden color.
- Season both sides generously with salt and pepper, pressing gently to help seasonings adhere.
- If you're using frozen fish, make sure it's completely thawed and all excess moisture is removed.
- Spread the vegetable mixture evenly across your prepared sheet pan.
- Create spaces in your vegetable mixture, then nestle the seasoned fish fillets among the tomatoes and olives.
- Arrange vegetables around the fish so they create little pockets of flavor while supporting the fillets.
Building Layers of Flavor
- Arrange lemon slices over and around the fish fillets – use about 6-8 slices for optimal flavor.
- Combine all fresh herbs in a small bowl and mix well.
- Sprinkle the fresh herb blend generously over the fish and vegetables, saving about 1 tablespoon for garnish.
- Drizzle the remaining olive oil evenly over the fish fillets and any exposed vegetables.
- Give everything a final light seasoning with salt and pepper if desired.
This layering technique allows all the flavors to meld together while keeping the fish moist and flaky. The lemon slices prevent the fish from drying out while adding that essential Mediterranean brightness.
The Perfect Bake
- Slide your sheet pan into the preheated oven on the center rack.
- Bake for 15-20 minutes, depending on the thickness of your fillets (thinner fillets need less time).
- Check for doneness at the 15-minute mark – the fish should be opaque and flake easily with a fork.
- Test the internal temperature with a meat thermometer – it should reach 145°F (63°C).
- Remove from oven when fish flakes easily and vegetables are tender and lightly caramelized.
- Let rest for 2-3 minutes before serving to allow juices to settle.
During baking, the juicy tomatoes will release their natural moisture, creating a light sauce that keeps everything moist. The edges of the vegetables will caramelize slightly, adding depth to the overall flavor profile.
- Step 1: Prepping Your Mediterranean Base
Toss the vegetables with oil, salt, and pepper to create the flavorful base.
- Step 2: Preparing the Fish Fillets
Nestle the fish fillets into the seasoned vegetable mixture.
- Step 3: Building Layers of Flavor
Layer with lemon and herbs to build flavor and keep fish moist.
- Step 4: The Perfect Bake
Bake until fish flakes and vegetables are tender with caramelized edges.
Professional Cooking Hints and Tips
Here's a game-changing tip: let your fish come to room temperature for 15 minutes before cooking. This simple step helps the fish cook more evenly, preventing the outside from overcooking while the center stays cold.
For extra flavor, create a quick red onion relish by mixing thinly sliced red onions with a pinch of salt and letting them sit for 10 minutes. This draws out harsh flavors and creates a mellower, sweeter taste.
If you want to add some richness, consider using a cast-iron skillet instead of a sheet pan. The fish will develop a slightly crispier bottom while staying tender inside.
Health Benefits and Serving Suggestions
This mediterranean baked fish recipe is a nutritional powerhouse. White fish provides lean protein and omega-3 fatty acids that support heart health, while the olive oil delivers healthy monounsaturated fats. The colorful vegetables add antioxidants, fiber, and essential vitamins.
For a complete Mediterranean meal, serve your baked fish over a bed of fluffy quinoa or alongside lemon herb rice. The dish pairs beautifully with roasted vegetables like zucchini, bell peppers, or asparagus. A dollop of homemade tzatziki sauce adds creamy coolness that complements the warm, herb-scented fish.
Recipe Variations and Substitutions
Transform this basic recipe into different Mediterranean-inspired dishes. For a Greek twist, add crumbled feta cheese and a handful of fresh spinach during the last 5 minutes of baking. Italian food lovers can incorporate sun-dried tomatoes and fresh basil for a Tuscan flavor profile.
Make it Spanish-style by adding smoked paprika and a few saffron threads to the olive oil before drizzling. For those following a Mediterranean diet strictly, this recipe fits perfectly into your meal planning rotation.
Vegetarians can adapt this technique using thick slices of eggplant or portobello mushrooms instead of fish. The same vegetable medley and cooking method work beautifully with plant-based proteins.
Equipment
While this recipe works in any oven-safe dish, a large sheet pan gives you the best results. The wide surface area allows vegetables to roast rather than steam, creating better flavor development. Parchment paper is your friend here – it prevents sticking and makes cleanup effortless.
A good fish spatula with a thin, flexible blade makes serving much easier. If you don't have one, a regular spatula works fine, just be gentle when transferring the delicate fish fillets to plates.
For those who love kitchen gadgets, a fish baker or oval baking dish creates an elegant presentation perfect for dinner parties. Le Creuset fish bakers work particularly well for this type of recipe.
Storage and Meal Prep Tips
Leftover baked mediterranean fish keeps beautifully in the refrigerator for up to 3 days when stored in an airtight container. The flavors actually develop and improve overnight, making it perfect for meal prep enthusiasts.
To reheat, place portions in a 350°F oven for 8-10 minutes, or use the microwave on medium power to prevent overcooking. The fish reheats best when covered with a damp paper towel to maintain moisture.
This recipe doesn't freeze well due to the delicate nature of cooked fish, but the vegetable mixture can be prepared ahead and refrigerated for up to 2 days before adding fresh fish and baking.
The Moisture Secret Behind Perfect Baked Mediterranean Fish
Here’s a little lesson I learned the hard way: the difference between dry fish and perfectly juicy baked Mediterranean fish comes down to timing. I used to leave it in “just a minute longer,” afraid it wouldn’t be done—only to pull out something overcooked and chalky. The real secret? Trust the process and let the baked Mediterranean fish finish cooking gently with its own warmth.
As soon as it turns opaque and starts to flake at the edges—but still has a slightly translucent center—I take it out. That carryover heat does the rest, keeping the texture silky and tender. It took a few tries (and a couple of fish I wished I could un-cook), but now, every time I make baked Mediterranean fish, it’s moist, flavorful, and never dry.
FAQ
Should fish be covered or uncovered when baking in the oven?
Fish is best baked uncovered to allow moisture to naturally evaporate and the surface to slightly caramelize. If you're using a delicate sauce or want extra moisture, a loose foil tent can help. But for that golden, flavorful finish—especially in baked Mediterranean fish—keeping it uncovered gives the best texture and allows the herbs to shine.
How do you keep fish moist when baking?
To keep fish moist, bake it just until it’s opaque and flakes easily—then remove it immediately. Fish continues to cook from residual heat, so slightly underbaking prevents dryness. Using ingredients like olive oil, citrus, or tomatoes—common in baked Mediterranean fish—also locks in moisture and infuses the fish with extra flavor as it cooks.
Can you overcook baked fish?
Yes, overcooking fish is easy—and it leads to dry, tough texture. Since fish cooks quickly, always keep an eye on it. Once it flakes easily and turns opaque but is still slightly translucent in the center, it’s ready. With baked Mediterranean fish, gentle baking and carryover heat ensure it stays tender, juicy, and flavorful.
