Ingredients
For the Fish
4 white fish fillets, such as cod, tilapia, or sea bass
2 cups cherry tomatoes
½ cup green olives, pitted
3 tablespoons olive oil
2 tablespoons butter, melted
4 garlic cloves, minced
1 tablespoon fresh lemon juice
1 teaspoon paprika
1 teaspoon Italian seasoning
½ teaspoon salt, or to taste
½ teaspoon black pepper
2 sprigs fresh rosemary
2 sprigs fresh thyme
2 tablespoons fresh parsley, chopped
Optional Garnishes
Fresh lemon wedges
Extra chopped parsley
Red pepper flakes
Freshly cracked black pepper
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a large baking dish with a small amount of olive oil to prevent sticking.
Choose a baking dish large enough to arrange the fish fillets in a single layer without overcrowding. This allows the heat to circulate evenly and helps the fish cook properly.
Step 2: Prepare the Garlic Butter Sauce
In a small mixing bowl, combine the melted butter, olive oil, minced garlic, fresh lemon juice, paprika, Italian seasoning, salt, and black pepper.
Whisk everything together until the ingredients are evenly distributed.
The olive oil and butter provide richness, while garlic and lemon juice add a wonderful balance of savory and bright flavors.
For additional heat, add a small pinch of crushed red pepper flakes.
Step 3: Prepare and Season the Fish
Pat the fish fillets dry using paper towels. Removing excess moisture helps the garlic butter sauce cling to the fish.
Arrange the fillets in the prepared baking dish, leaving a little space between each piece.
Brush both sides of the fish generously with the garlic butter mixture.
Make sure each fillet is evenly coated so the flavors are distributed throughout the dish.
If using frozen fish, thaw it completely in the refrigerator before preparing the recipe.
Step 4: Add the Cherry Tomatoes and Olives
Wash the cherry tomatoes and place them around the seasoned fish fillets.
Scatter the pitted green olives evenly throughout the baking dish.
Drizzle any remaining garlic butter mixture over the tomatoes and olives.
Place the fresh rosemary and thyme sprigs between the fish fillets.
During baking, the tomatoes will soften and release their juices, creating a flavorful sauce with the garlic butter and herbs.
Step 5: Bake Until Tender and Flaky
Transfer the baking dish to the preheated oven.
Bake for approximately 20–25 minutes, depending on the thickness of the fish fillets.
Thin fillets may cook more quickly, so begin checking them after 12–15 minutes.
The fish is ready when it becomes opaque, flakes easily with a fork, and reaches an internal temperature of 145°F (63°C) at its thickest point.
Avoid baking longer than necessary, as overcooked fish can become dry.
Step 6: Add the Finishing Touches
Carefully remove the baking dish from the oven.
Discard the woody rosemary and thyme stems if desired.
Using a spoon, gently drizzle the warm garlic butter sauce and roasted tomato juices over each fish fillet.
Sprinkle freshly chopped parsley over the entire dish.
Finish with an additional squeeze of fresh lemon juice for a bright, refreshing flavor.
Step 7: Serve and Enjoy
Serve the Mediterranean garlic butter baked fish immediately while warm.
Place each fish fillet on a serving plate with a generous spoonful of roasted cherry tomatoes and olives.
Drizzle the remaining garlic butter sauce over the fish.
Pair with lemon rice, roasted potatoes, steamed vegetables, or warm bread for a complete and satisfying meal.
Helpful Cooking Tips
Choose fresh fish fillets with a mild aroma and firm texture for the best results.
Use fillets of similar thickness so they cook evenly.
Pat the fish dry before seasoning to help the sauce adhere properly.
Use freshly minced garlic for a stronger, more aromatic flavor.
Fresh lemon juice provides a brighter taste than bottled lemon juice.
Avoid overcrowding the baking dish because the fish and vegetables need room to cook evenly.
Use pitted olives to make the finished dish easier to eat.
Adjust the amount of salt depending on how salty your olives are.
Check the fish early if using thin tilapia fillets.
For a lightly golden finish, broil the fish for the final 1–2 minutes, watching closely to prevent burning.
