Thin flounder fillets are perfect for stuffing, and these Florentine-style flounder fillets are rolled around a savory seasoned spinach mixture. It's an elegant and delicious dish that's surprisingly easy to make and ready for the table in just under an hour.

Florentine describes a culinary style that originated in Florence, Italy. Best known for eggs Benedict, the dishes are often characterized by spinach cooked with eggs, fish, or poultry, then finished in a savory sauce. This dish follows that custom by rolling cooked spinach, onion, and oregano into flounder fillets, then topping the baked fish with a creamy white wine sauce.

The key to this recipe is to precook the spinach. Steaming for two minutes or blanching for less than a minute are the easiest methods. Neither requires butter or oil, so the spinach is pure and ready to be seasoned. However, you want to let the spinach cool entirely and squeeze out any moisture before using it in the Florentine flounder recipe.

Once the fish and sauce are ready, plate your stuffed fish and sprinkle it with a bit of grated Parmesan and sprinkle of paprika. A simple side dish of baked or roasted potatoes would be perfect with the fish, and rice is another good choice. Add a tossed salad or mixed greens for a memorable meal.
