Creating the amazing Mediterranean Baked Fish is straightforward if you follow these simple steps:

1. Preheat Oven: Start by preheating your oven to 400°F (200°C).
2. Prepare the Baking Dish: Lightly grease a baking dish with olive oil.
3. Season the Fish: Pat the fish fillets dry with paper towels. Season both sides with salt, black pepper, and dried oregano.
4. Sauté Vegetables: In a skillet, heat the olive oil over medium heat. Add the sliced onions and cook until translucent, about 5 minutes. Add the bell pepper and zucchini, cooking until just tender. Stir in the minced garlic and cook for an additional minute.
5. Arrange Ingredients: Spread the sautéed vegetables evenly across the bottom of the prepared baking dish. Place the seasoned fish fillets on top of the vegetables.
6. Add Tomatoes and Herbs: Scatter the cherry tomatoes, parsley, and dill over the fish fillets. Drizzle with lemon juice and sprinkle the lemon zest on top for added flavor.
7. Cover and Bake: Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes.
8. Uncover and Finish Cooking: After 20 minutes, remove the foil and continue to bake for an additional 5-10 minutes, or until the fish flakes easily with a fork and is cooked through.
9. Serve: Remove from the oven and let the dish cool for a few minutes. Garnish with extra herbs and lemon wedges.
10. Enjoy: Serve this Mediterranean Baked Fish warm, accompanied by a side of crusty bread or a simple salad.

These straightforward steps ensure that you’ll have a delicious and satisfying dish ready in no time.
