How to Make Mediterranean Baked Fish
-
Preheat: Begin by setting your oven to 400°F (200°C). While the oven heats, grease your favorite baking dish with olive oil to ensure a non-stick finish.
-
Prep Vegetables: In a large mixing bowl, combine sliced red onion, bell peppers, cherry tomatoes, minced garlic, and kalamata olives. Drizzle with olive oil and sprinkle with oregano and paprika. Toss gently until everything is well-coated and fragrant.
-
Layer Ingredients: Spread the vegetable mixture evenly in the bottom of the baking dish. Place your white fish fillets on top, skin side down if applicable. Squeeze fresh lemon juice over the fish and season with lemon zest, salt, pepper, and a touch of oregano for extra flavor.
-
Bake: Place the tray in your preheated oven and bake uncovered for 20-25 minutes. The fish should be opaque and flake easily with a fork, while the vegetables become tender and slightly caramelized.
-
Serve: Once done, remove the dish from the oven. Garnish with freshly chopped parsley and serve with lemon wedges, as well as a side of rice, roasted potatoes, or crusty bread to soak up all those delicious juices.
Optional: A sprinkle of red pepper flakes adds a nice kick!

Mediterranean Baked Fish Recipe FAQs
How do I choose the right fish for Mediterranean Baked Fish?
Absolutely! For this recipe, it's best to select fresh white fish fillets like cod, halibut, or tilapia. When shopping, look for firm, moist fillets that have a clean, ocean-like smell. Avoid fish that has a strong or fishy odor, as freshness is key.
What’s the best way to store leftovers of Mediterranean Baked Fish?
After enjoying your meal, transfer any leftovers to an airtight container and store in the refrigerator for up to 2 days. To reheat, I recommend gently warming it in the oven at 350°F (175°C) for about 15-20 minutes. This method helps retain the dish's moisture and prevents the fish from becoming dry.
Can I freeze Mediterranean Baked Fish?
Yes! To freeze, wrap the dish tightly in plastic wrap, then in aluminum foil, and store in the freezer for up to 3 months. When you're ready to enjoy it again, thaw it overnight in the refrigerator. Reheat gently in the oven to preserve the dish's flavor and texture.
What should I do if my fish isn’t cooking evenly?
If you notice that your fish isn’t cooking evenly, it could be due to overcrowding in the baking dish. I suggest spreading the vegetable mix and the fish fillets in a single layer without overlapping. Also, flipping the fish halfway through the cooking process can help achieve an even cook on both sides.
Is it safe for pets and common allergies?
When it comes to pets, it's best to keep the Mediterranean Baked Fish away from dogs and cats, especially if it contains garlic, as it can be harmful to them. If you have allergies, ensure that all ingredients, particularly the olives and any added spices, are free from allergens like gluten or dairy before preparing this healthy dish.
