Ingredients You Need

Fish

1.5 to 2 pounds white fish fillets
- Great options: cod, haddock, halibut, tilapia, or snapper
- Choose fillets about 1 inch thick so they cook evenly
- Frozen fish works well if you thaw it fully and pat it very dry

Mediterranean topping

2 tablespoons extra virgin olive oil
3 cloves garlic, finely minced
1 teaspoon kosher salt, plus more to taste
1/2 teaspoon freshly ground black pepper
1 teaspoon dried oregano
1 teaspoon dried basil or Italian seasoning
1/2 teaspoon smoked paprika or sweet paprika
1/4 teaspoon red pepper flakes, optional for a little heat
Zest of 1 lemon
Juice of 1 large lemon (about 3 tablespoons, use fresh if possible)
1 cup cherry or grape tomatoes, halved
- Pantry shortcut: use 1 cup canned diced tomatoes, well drained
1/3 cup pitted Kalamata olives, roughly chopped
- You can use green olives if that is what you have
2 tablespoons capers, drained (optional but tasty)
1/4 cup finely chopped red onion or shallot
2 tablespoons chopped fresh parsley
2 tablespoons chopped fresh basil or cilantro, optional

To finish

Extra lemon wedges for serving
Extra chopped herbs for garnish
A drizzle of good olive oil on top

Equipment

9×13 inch baking dish or similar oven safe pan
Small bowl for mixing the topping
Cutting board and sharp knife
Microplane or small grater for lemon zest
Measuring spoons and cups
Oven mitts that you actually use and do not just admire

Quick Tips & substitutions

Pat the fish very dry so the topping sticks and the fish roasts instead of steams.
Use frozen fillets if needed, but thaw them in the fridge overnight and dry them well.
Swap white fish with salmon if you prefer a richer flavor and adjust cook time a few minutes longer.
Replace fresh cherry tomatoes with well drained canned diced tomatoes when your fridge looks empty.
Use jarred minced garlic on busy nights, but cut the amount slightly since it tastes stronger.
Skip olives or capers if you do not enjoy briny flavors and add extra tomatoes or onion instead.
Use dried herbs only if you lack fresh ones and bump the dried oregano or Italian seasoning by a pinch.
Line the baking dish with parchment for easier cleanup if the dish tends to stick.
Check fish a few minutes early since every oven runs a little different.
Add more red pepper flakes if you like heat or leave them out for kids.

How to Make Tasty Easy Mediterranean Baked Fish Recipe

Step 1: Preheat and prep the fish

Preheat your oven to 400°F and position a rack in the center. Lightly grease your baking dish with a teaspoon of olive oil. Lay the fish fillets in a single layer in the dish and tuck thin ends under so the pieces cook evenly.

Sprinkle the fish with a pinch of salt and pepper on both sides. Pat the fillets dry again if they release more moisture while you season them. Set the dish aside while you mix the topping.

Step 2: Mix the Mediterranean topping

In a medium bowl add olive oil, minced garlic, salt, pepper, dried oregano, dried basil or Italian seasoning, smoked paprika, red pepper flakes, lemon zest, and lemon juice. Stir until the mixture looks well combined and fragrant. Add the halved cherry tomatoes, chopped olives, capers, red onion, and chopped parsley.

Toss everything until the vegetables and olives look coated in the lemony oil mixture. Taste a tomato and adjust salt, pepper, or lemon juice to your liking. The mixture should taste bright, a little salty, and very flavorful.

Step 3: Top the fish

Spoon the Mediterranean mixture evenly over the fish fillets. Cover each piece so the topping protects the fish and keeps it juicy. Pour any remaining liquid from the bowl over the top.

Drizzle a small extra splash of olive oil across the dish if it looks dry. The topping should look colorful with tomatoes and olives scattered over every fillet. Take a second to admire it because it already looks like dinner.

Step 4: Bake the fish

Place the baking dish in the hot oven. Bake for 12 to 18 minutes, depending on the thickness of your fillets. Thin tilapia may finish closer to 12 minutes, while thick cod or halibut may need the full time.

Check the fish at 10 minutes so you avoid overcooking. The fish should flake easily with a fork and look opaque all the way through. If you use a thermometer, aim for 135 to 140°F in the thickest part.

Step 5: Finish and garnish

Remove the dish from the oven and let the fish rest for 3 minutes. This short rest helps the juices settle so the fish stays moist when you serve it. Squeeze a little extra lemon juice over the top if you love citrus.

Sprinkle with more fresh parsley or basil for color and freshness. Drizzle a tiny bit more olive oil over the tomatoes and olives if they look dry. Serve the fish straight from the baking dish while it still feels hot and flaky.

Storage Success

Let the baked fish cool to room temperature, then store it in an airtight container in the fridge for up to 2 days. Keep the fish and topping together so the flavors continue to mingle and stay juicy. Reheat gently in a covered skillet over low heat or in the oven at 300°F until warm, and avoid high heat so the fish does not dry out.

You can also enjoy the leftovers cold over salad, which keeps the texture nicer than aggressive reheating. If the topping looks a little dry the next day, add a small splash of olive oil and a squeeze of lemon to wake it back up.
