Baked Greek Fish with Tomatoes and Onions – “Plaki” – Technique

Use this page to make the Baked Fish Plaki recipe on my blog. This recipe is a traditional baked fish dish my mother passed down to me and I have made hundreds of times. Once, you learn the basics to this method, you can create your own special dish.  I prefer fresh fish at all times. You can use Cod, Halibut or any fish that can stand up with baking without falling apart. No fillets, please. But, if I’m in a pinch, and I need dinner made in a hurry, I always stock my freezer with frozen fillets.

I used Costco’s Wild Caught Cod Fillets by Trident . As you can see one bag gives you eight nice size pieces.

Wash and place fillets in a large oiled baking dish.

For the Sauce: Place olive oil in frying pan. Add sliced onions and garlic. Cook on medium for 10 minutes until soft. Do not brown.

Tomato mixture for the Plaki Greek Dish
Add remaining ingredients, and cook for another 10 minutes.

Pour sauce over fish and bake for 45 minutes. I like to arrange the fish on a platter if yo have a buffet style dinner.

If I wanted to add potatoes, when would I put them in?

Hi Sheryl,
Place the thinly sliced potatoes under the fish at the very beginning. They will take a while to cook.
Or you can precook the potatoes- boil them and thinly slice and add on top with the onions. Soft red potatoes or white potatoes will work.
Thank you for asking,
Mary
