• ¼ cup extra virgin olive oil
• 1 tablespoon fresh lemon juice
• 1 teaspoon lemon zest
• 2 garlic cloves, minced

• ½ teaspoon dried thyme
• ½ teaspoon paprika
• ½ teaspoon salt
• ¼ teaspoon black pepper

How to Make Mediterranean Baked Fish

Follow these detailed steps to create restaurant-quality baked fish in your own kitchen.

Step 1: Preheat Your Oven

Set your oven to 400°F (200°C) and allow it to fully preheat. This step is more important than you might think—a properly heated oven ensures even cooking and helps the fish retain its natural moisture while developing beautiful golden edges.

Step 2: Create the Aromatic Marinade

In a small mixing bowl, combine the olive oil, lemon juice, lemon zest, minced garlic, dried oregano, thyme, paprika, salt, and black pepper. Whisk everything together vigorously until the oil and lemon juice emulsify into a cohesive, fragrant marinade. You’ll notice the color brightening and the aroma intensifying as the ingredients blend.

This marinade is the flavor foundation of the entire dish. The olive oil carries the herbs and garlic, while the lemon adds brightness that cuts through the richness of the fish.

Step 3: Prepare the Fish

Arrange your fish fillets in a lightly greased baking dish or one lined with parchment paper for easy cleanup. Pour the marinade over the fillets generously, using a spoon or pastry brush to ensure each piece is thoroughly coated on all sides. Don’t be shy—you want every bite infused with those Mediterranean flavors.

Step 4: Layer in the Vegetables

Scatter the halved cherry tomatoes, Kalamata olives, and thinly sliced red onions over and around the fish fillets. As these vegetables bake, they’ll release their juices, creating a flavorful sauce that mingles with the marinade. The visual presentation is stunning too—vibrant reds, deep purples, and fresh greens create an appetizing display.

Step 5: Bake to Perfection

Place the baking dish in your preheated oven and bake uncovered for 15 to 18 minutes. Cooking time varies slightly depending on the thickness of your fillets. You’ll know the fish is ready when it flakes easily with a fork and appears opaque throughout. The internal temperature should reach 145°F (63°C) for food safety.

Step 6: Final Touches

Remove the dish from the oven carefully. Sprinkle fresh chopped parsley over the top for a pop of color and fresh herbaceous flavor. Serve each portion with lemon wedges on the side, allowing diners to add extra brightness according to their preference.

Expert Tips for Outstanding Results

Selecting Your Fish

The fish you choose makes a significant difference. Look for mild, white-fleshed varieties like tilapia, cod, halibut, snapper, or sea bass. These fish have a delicate flavor that absorbs the marinade beautifully without overpowering the other ingredients. Always choose boneless, skinless fillets for the easiest serving and eating experience.

If you’re working with frozen fish, plan ahead. Thaw fillets completely in the refrigerator overnight, then pat them thoroughly dry with paper towels before marinating. Excess moisture prevents proper browning and dilutes the marinade.

Timing is Everything

The difference between perfectly cooked and overcooked fish is often just a minute or two. Start checking for doneness at the 15-minute mark, especially with thinner fillets. The fish should flake easily when tested with a fork and look opaque throughout, but still appear moist and tender.

Fresh vs. Dried Herbs

While dried herbs work wonderfully in this recipe, fresh herbs elevate it to another level. If substituting fresh oregano or thyme for dried, use three times the amount—the flavor is less concentrated in fresh herbs. Fresh herbs also add visual appeal with their vibrant green color.

Advance Preparation

For even more flavor, marinate the fish in the refrigerator for 30 minutes before baking. This extra time allows the seasonings to penetrate deeper into the flesh. Just cover the dish with plastic wrap and refrigerate until you’re ready to bake.

Vegetable Variations

Feel free to customize the vegetable mix based on what you have available or prefer. Thinly sliced bell peppers, zucchini ribbons, or fennel all work beautifully. Just keep the pieces relatively small so they cook through in the same time as the fish.

Perfect Pairings

This Mediterranean baked fish is wonderfully versatile and complements many side dishes:

• Fluffy couscous soaks up the delicious pan juices
• Rice pilaf adds a classic, comforting element
• Roasted potatoes provide satisfying heartiness
• Greek salad keeps things light and refreshing
• Steamed asparagus or green beans add vibrant color and nutrition
• Crusty bread is perfect for mopping up every last bit of sauce

Consider finishing with a drizzle of extra lemon juice or a dollop of creamy tzatziki sauce for added richness.

Storage and Reheating

Storing Leftovers:
Allow the fish to cool completely before transferring to an airtight container. Refrigerate for up to 2 days for best quality and food safety.

Reheating:
For optimal results, reheat in a 325°F (165°C) oven for 8 to 10 minutes, covered loosely with foil to prevent drying. If you’re pressed for time, the microwave works, but cover the fish with a damp paper towel to maintain moisture.

Meal Prep Strategy

This recipe scales beautifully for meal prepping. Double the ingredients and divide into individual portions alongside your chosen grain and vegetables. Store in airtight containers and refrigerate. The flavors actually develop and deepen slightly overnight, making next-day portions even more delicious.
