Flounder isn’t the first fish that comes to mind when thinking about the Mediterranean diet. But wild-caught flounder has many nutritional benefits. This Mediterranean Flounder recipe is sure to become a favorite.
Flounder is a healthy saltwater fish with a mild flavor. It is high in vitamin B12, vitamin D, and offers omega-3 fatty acids. It’s a low-fat, low-calorie source of protein.
Its slightly sweet mild flavor makes it easy to create meals around. This particular dish is very easy to make and has a lot of flavor. I served it with mashed potatoes and peas. It would also work well with rice or pasta, and your vegetables of choice.

Ingredients
- 1 pound flounder filets (rinsed and patted dry)

- Preheat oven to 385 degrees F. Prepare a large baking dish by adding a light coating of olive oil. Arrange the fish filets in a single layer.
- In a large mixing bowl, add the tomatoes, onion, olives, garlic, cherry peppers (if using), oregano, salt, and pepper. Finally, pour on the olive oil, and give everything a good toss to combine.
- Pour the tomato mixture over the flounder. Arrange it evenly over all of the fish.
