Ingredients
Four white fish fillets such as cod, haddock, halibut, or sea bass
Two medium zucchini, sliced into rounds
One yellow bell pepper, chopped
One red bell pepper, chopped
One and a half cups cherry tomatoes
One medium red onion, cut into wedges
Half a cup Kalamata olives
Four garlic cloves, minced
Three tablespoons extra virgin olive oil
One tablespoon melted butter (optional)
Juice of one lemon
One teaspoon lemon zest
One teaspoon dried oregano
Half teaspoon dried thyme
Half teaspoon paprika
Half teaspoon garlic powder
Salt to taste
Half teaspoon black pepper
One tablespoon chopped fresh parsley
One tablespoon chopped fresh dill
One lemon, sliced into thin rounds
Lemon wedges for serving
Instructions
Preheat the oven to 400°F (200°C). Lightly grease a large baking dish or sheet pan with olive oil.
Place the zucchini, bell peppers, cherry tomatoes, red onion, and Kalamata olives into the baking dish. Drizzle with one tablespoon of olive oil and season lightly with salt, pepper, oregano, and thyme. Toss until evenly coated.
In a small bowl, whisk together the remaining olive oil, melted butter, garlic, lemon juice, lemon zest, paprika, garlic powder, oregano, salt, and black pepper.
Pat the fish fillets dry with paper towels and place them on top of the vegetables. Brush the garlic herb mixture generously over each fillet.
Arrange the lemon slices around and on top of the fish.
Bake for 20 to 25 minutes, or until the fish flakes easily with a fork and the vegetables are tender and lightly roasted.
Remove from the oven and sprinkle with fresh parsley and dill.
Allow the fish to rest for 2 to 3 minutes before serving.
Serve warm with rice, quinoa, couscous, roasted potatoes, or crusty bread to enjoy the flavorful pan juices.
Tips
Choose firm white fish fillets that are similar in thickness for even cooking.
Pat the fish completely dry before seasoning to help the herbs stick better.
Cut the vegetables into similar-sized pieces so they roast evenly.
Fresh garlic provides the richest flavor compared to garlic powder.
Do not overcook the fish, as it can become dry.
Use extra virgin olive oil for authentic Mediterranean flavor.
Fresh lemon juice adds brightness and balances the richness of the olive oil.
Add delicate herbs like parsley and dill after baking to preserve their fresh taste.
For extra caramelization, broil the dish for the final 2 minutes.
Store leftovers in an airtight container in the refrigerator for up to two days.
Variations
Replace cod with salmon, halibut, tilapia, sea bass, or mahi-mahi.
Add asparagus, mushrooms, eggplant, or broccoli for extra vegetables.
Include capers for a tangy Mediterranean flavor.
Sprinkle crumbled feta cheese over the vegetables before serving.
Use smoked paprika instead of regular paprika for a smoky taste.
Add crushed red pepper flakes for a spicy version.
Replace butter with additional olive oil for a dairy-free meal.
Serve over cooked quinoa or couscous to make it even more filling.
Add artichoke hearts for extra Mediterranean character.
Top with toasted pine nuts or sliced almonds for added crunch.
