Easy Greek Oven Baked Fish (Psari Plaki) Recipe

What’s Psari Plaki?

Psari (pronouned p-SAR-ee, with an emphasis on the SAR) means fish in Greek. Give it a try! Plaki (plak-EE) is actually a classic Greek cooking method meaning baking in the oven with olive oil, vegetables and herbs.

So psari plaki is simply a delicious Greek fish dish baked in the oven in tomatoes and onions and other delicious and simple Greek flavors. It’s definitely one of those recipes that everyone in Greece has their own version of (like moussaka, pastitsio and gemista!).

I hope you enjoy mine!

5 star review *****

Wow. Made it this evening and just added it to my list of regular recipes. Served with boiled rice and Greek salad. Time to see what other delights this site has to offer… (Fiona)

Ingredients

For the tomato and onion sauce

Onions: The recipe starts with 2 whole large onions. Regular white onions are fine.

Garlic: You’ll need 3 large cloves.

Good quality olive oil: To slowly cook the onions and garlic in.

Greek herbs and spices: Paprika, cinnamon & dried oregano. You could say cinnamon is the secret ingredient in many traditional Greek dishes. Don’t skip this!

Tomatoes, tomato paste and red or white wine: Mix together these 3 before pouring them into the sauce with the onions. It doesn’t matter which wine, but you can’t go wrong with a full-bodied red such as Cabernet or Merlot.

Honey: For a touch of sweetness to balance out the acidity of the tomatoes.

Fresh basil or parsley: I prefer the fresh and subtle anise flavor of basil, but by all means use parsley instead if basil isn’t available.

What kind of fish to use

Any kind of white fish fillets will work really well for this Mediterranean fish recipe. In Greece, tsipoura (sea bream) would be a great choice. Cod, haddock, snapper, tilapia, bass or grouper would all work too.

I like to use local Australian wild caught snapper – just because that’s what’s commonly available, it’s reasonably priced, and it tastes good.

I’d definitely look for a good quality, wild caught fish if the budget allowed. But you can use whatever white fish is economical and widely available where you live.

How to make it

This is so simple you won’t believe it. Essentially, there are only 3 main steps.

Step 1: Start by gently cooking the sliced onions for about 10 minutes, then add garlic. You might think it looks like a lot of onions. It is, but that’s OK!

Step 2: Then add the can of tomatoes, tomato paste and the wine, plus all the yummy Greek herbs and spices (and of course salt and pepper).

Step 3: Let simmer for about 15 minutes. Then stir in the honey and fresh herbs. Pour over the fish and bake for about 30 minutes.

How to serve

We tend to keep our wonderful Greek baked fish or ‘psari plaki’ simple:

Serve everyone some of the delicious oven roasted fish in the yummy and healthy Mediterranean tomato onion sauce.

Serve a plate of quick and easy grilled bread with olive oil and salt, AND…

Optionally, serve a big traditional Greek salad on the side (if you have the energy, or if you’re serving this meal to guests!)

Other side dish possibilities could include:

Rice! Several readers have enjoyed this Greek style baked fish with rice on the side. This Greek lemon rice is perfect, and you can make it either on your stove-top or in your Instant Pot (pressure cooker).

Potatoes. I recommend trying this ridiculously good crispy Greek potato recipe! Or these classy mini garlic parmesan hasselback potatoes – especially if you’re entertaining.

Recipe FAQ

Should I cover the fish when baking it?

No, there is no need to cover the dish for this recipe, which makes it even easier!

How do I know when the fish is cooked?

To check if fish is done, just insert a fork in the thickest part and twist it to see if the fish easily flakes. If it still looks opaque in the middle, give it a few more minutes before checking again. If you have a food thermometer, the internal temperature should be 145F/63C.

Can I reheat the leftovers?

Fish cooks quickly and can be easily overcooked, so it’s always best eaten when first cooked. If you have leftovers, however, you can reheat them gently in the oven. Just cover with aluminium foil and warm through at around 275F/135C for about 15 minutes or until piping hot again.

I don’t recommend using the microwave to reheat this. It’s too easy to overheat the fish, making it tough and dry.
