Total Time: About 30–35 minutes

Ingredients
For the Fish
1½ pounds (680 g) cod, haddock, halibut, or other firm white fish fillets
2 tablespoons extra-virgin olive oil, divided
½ teaspoon salt
¼ teaspoon black pepper
1 teaspoon dried oregano
½ teaspoon dried thyme
½ teaspoon paprika, optional
Mediterranean Topping
1 cup cherry tomatoes, halved
½ cup Kalamata olives, pitted and sliced
½ small red onion, thinly sliced
3 cloves garlic, minced
1 tablespoon capers, optional
1 lemon
¼ cup fresh parsley, chopped
¼ teaspoon red pepper flakes, optional
Optional Finish
¼ cup crumbled feta cheese
Fresh parsley
Lemon wedges
Instructions
1. Prepare the oven
Preheat your oven to 400°F (200°C). Lightly grease a medium baking dish with 1 tablespoon of olive oil.
2. Prepare the fish
Pat the fish fillets thoroughly dry with paper towels. Place them in the baking dish in a single layer.
Drizzle with the remaining olive oil and season with salt, pepper, oregano, thyme, and paprika.
3. Make the Mediterranean topping
In a bowl, combine the cherry tomatoes, olives, red onion, garlic, capers, red pepper flakes, and chopped parsley.
Add the zest and juice of ½ lemon and toss everything together.
4. Assemble
Spoon the tomato-olive mixture evenly over and around the fish.
Slice the remaining lemon into thin rounds and arrange them over the fish.
5. Bake
Bake uncovered for approximately 15–20 minutes, depending on the thickness of the fillets.
The fish is ready when it is opaque, flakes easily with a fork, and reaches a safe internal temperature of 145°F (63°C). Similar baked-fish recipes use roughly 14–20 minutes depending on fillet thickness.
6. Finish
Remove from the oven and spoon the flavorful tomato-olive juices over the fish.
Sprinkle with fresh parsley and optional feta. Serve immediately with lemon wedges.

Tips for Perfect Baked Fish
Pat the fish dry before seasoning so it roasts rather than steams.
Don’t overcrowd the baking dish.
Use fresh lemon juice for the brightest flavor.
Go easy on added salt because olives and capers are already salty.
Cooking time depends heavily on the thickness of your fish fillets.
Let the fish rest for a couple of minutes before serving.
