Ingredients For Italian Style Flounder Recipe
Flounder: A mild, delicate white fish that works perfectly with Italian flavors.
Olive oil: Adds richness and helps to cook the fish evenly.
Cherry tomatoes: Provide a burst of sweetness and acidity.
Garlic: Adds a robust, aromatic flavor to the dish.
Dried oregano: A classic Italian herb that enhances the overall taste.

Technique Tip for This Recipe
When preparing the flounder fillets, make sure they are of uniform thickness to ensure even cooking. If the fillets are thicker on one end, consider gently pounding them with a meat mallet to achieve a consistent thickness. This will help the fish cook evenly and prevent any parts from being undercooked or overcooked.

garlic - Substitute with shallots: Shallots offer a milder, slightly sweet flavor that can complement the dish well.
dried oregano - Substitute with dried basil: Dried basil provides a different but equally aromatic herb flavor that pairs well with fish.

How to Store / Freeze This Dish
Allow the flounder to cool to room temperature before storing. This helps prevent condensation, which can make the fish soggy.
Transfer the flounder fillets and the tomato mixture into an airtight container. Ensure the container is sealed tightly to maintain freshness.
Store the container in the refrigerator if you plan to consume the dish within 2-3 days. The flounder will remain flavorful and safe to eat during this period.
For longer storage, place the cooled flounder fillets and tomato mixture in a freezer-safe container or heavy-duty freezer bag. Label the container with the date to keep track of its freshness.
When freezing, try to remove as much air as possible from the container or bag to prevent freezer burn, which can affect the texture and taste of the flounder.
To reheat refrigerated flounder, preheat your oven to 350°F (175°C). Place the fillets and tomato mixture in an oven-safe dish and cover with aluminum foil. Heat for about 10-15 minutes or until warmed through.
If reheating from frozen, allow the flounder to thaw in the refrigerator overnight. Once thawed, follow the same reheating instructions as for refrigerated flounder.
Alternatively, you can reheat the flounder in a microwave. Place the fillets and tomato mixture in a microwave-safe dish, cover, and heat on medium power in 1-minute intervals until hot. Be cautious not to overheat, as this can dry out the fish.
Garnish with fresh parsley after reheating to refresh the dish and add a burst of color and flavor.

Microwave Method:
- Place the flounder on a microwave-safe plate.
- Cover with a microwave-safe lid or a damp paper towel to prevent drying out.
- Microwave on medium power for 1-2 minutes.
- Check the fish and continue heating in 30-second intervals until warmed through.
Steam Method:
- Set up a steamer basket over a pot of simmering water.
- Place the flounder fillets in the steamer basket.
- Cover and steam for about 5-7 minutes, or until the fish is heated through.
