How to Make Lightly grease a baking dish with olive oil
Step 1: Preheat the Oven
Start by setting your oven to 400°F (200°C). Preheating is essential because it ensures your fish cooks evenly from the moment it goes in, locking in moisture and flavor.
Step 2: Lightly Grease a Baking Dish with Olive Oil
This is where the key phrase comes in. Lightly greasing a baking dish with olive oil not only prevents your fish and veggies from sticking but also adds a subtle, aromatic layer of flavor as the olive oil warms. Use a brush or a paper towel to spread a thin, even coat over the bottom and sides of the dish.
Step 3: Season the Fish
Pat your fish fillets dry to help the seasonings stick better. Sprinkle both sides generously with salt, black pepper, and dried oregano. This simple seasoning enhances the natural flavors without overpowering the delicate fish.
Step 4: Sauté the Vegetables
In a skillet, heat a bit of olive oil and add your sliced onions. Cook until they become translucent and sweet, about 5 minutes. Add the bell pepper and zucchini, cooking just until tender to maintain a bit of bite. Finally, stir in the minced garlic for one minute to release its fragrance without burning.
Step 5: Assemble the Dish
Spread the sautéed vegetables evenly in your baking dish, which you previously prepared by lightly greasing a baking dish with olive oil. Place the seasoned fish fillets on top, then scatter the halved cherry tomatoes, parsley, and dill over the fish for bursts of color and fresh herb flavor.
Step 6: Add Lemon Juice and Zest
Drizzle the lemon juice evenly across the fish and vegetables, then sprinkle the lemon zest on top. This adds a bright, citrus punch that balances the medley of savory ingredients perfectly.
Step 7: Cover and Bake
Cover the dish tightly with foil to keep the steam in, which gently cooks the fish and keeps it moist. Bake for 20 minutes in the preheated oven.
Step 8: Uncover and Finish Baking
Remove the foil and continue baking for another 5 to 10 minutes until the fish flakes easily with a fork and the vegetables are tender and inviting. This final step caramelizes the top slightly and intensifies the flavors.
Step 9: Rest and Serve
Let the dish cool for a few minutes outside the oven to let the flavors settle. Garnish with extra chopped herbs and lemon wedges.
How to Serve Lightly grease a baking dish with olive oil

Garnishes
Fresh, chopped parsley and dill brighten the plate and amp up the herbal notes, while lemon wedges add a fresh burst of acidity that’s irresistible when squeezed over the fish at the table. A little drizzle of extra virgin olive oil right before serving brings everything together with a silky sheen.
Side Dishes
This dish pairs beautifully with crusty rustic bread to soak up the delicious juices, a crisp green salad with a light vinaigrette, or even fluffy couscous for a heartier option. Each side adds a different texture and balance that complements the baked fish’s tender perfection.
Creative Ways to Present
Serve your Mediterranean Baked Fish family-style in the baking dish you carefully prepared by lightly greasing a baking dish with olive oil — it looks rustic and inviting right out of the oven. Alternatively, you can plate individual fillets over a bed of sautéed greens or orzo pasta, garnishing each plate with fresh herbs and a lemon wedge for an elegant touch.
Make Ahead and Storage
Storing Leftovers
Cool leftover Mediterranean Baked Fish to room temperature before transferring to an airtight container. Keep refrigerated and consume within 2 days for the best flavor and texture. The fish remains moist, and the vegetables retain their vibrant character.
Freezing
If you want to save some for later, freeze the cooked fish and veggies in a freezer-safe container. Make sure your baking dish was lightly greased with olive oil first before freezing leftovers back in the dish, as that layer helps protect the texture upon reheating. For optimal freshness, use within 1 month.
Reheating
Gently reheat in a preheated 350°F oven, covered with foil to prevent drying out. About 10-15 minutes should do, depending on how much you’re warming. Avoid microwaving if possible, to keep the fish tender and flavors intact.
