Baked Fish Plaki with Tomatoes and Onions

I have been making Plaki which is baked fish with tomatoes for years for my friends and family. It is fast and easy to prepare and a delicious main dish served with a salad and fresh bread. Plaki is simply an onion-mixture with tomatoes cooked down with wine and cinnamon. I use any white  fish, halibut, bass, or cod. The aroma of this dish takes me back to the seaports of Greece. This special dish was inspired by my walks along our coastal waters in California. For more detailed  cooking instructions, I have a special section called Cooking Techniques for Baked Fish with Tomatoes and Onions.

Hi Mary,
The fish was delicious. I bought some fresh rockfish from Canada which held up nicely to the sauce. I think next time I may add some capers and kalamata olives. The fish wasn’t very thick and was done in about 20 minutes. I added a simple spinach salad. Larry loved it and ate the leftovers for breakfast!
Thanks for sharing!
