flounder
Flounder is an excellent source of lean, high-quality protein while remaining low in fat and calories. It provides important nutrients including selenium, niacin, and vitamin B12, along with omega-3 fatty acids, though in lower quantities than oily fish species.
About
Flounder is a flatfish belonging to the family Pleuronectidae or Bothidae, comprising numerous species found in coastal waters of temperate and subtropical regions worldwide. The most commercially important species include the European flounder (Platichthys flesus), summer flounder or fluke (Paralichthys dentatus), and olive flounder (Paralichthys olivaceus). Flounders are characterized by their distinctive flat, compressed body structure with both eyes positioned on the same side of the head—an adaptation to their benthic lifestyle on the seafloor. The upper side is typically brown, gray, or olive-colored with mottled patterns for camouflage, while the underside is pale or white. The flesh is lean, white, and delicate with a mild, slightly sweet flavor and a firm yet tender texture when properly cooked.
Culinary Uses
Flounder is valued in cuisines worldwide for its mild flavor, delicate texture, and versatility. It is commonly prepared by pan-searing, baking, poaching, or steaming—cooking methods that preserve the tender flesh. In French cuisine, Dover sole (a specific flounder species) is considered a premium preparation, often served meunière or simply with brown butter and lemon. Asian cuisines feature flounder in steamed whole-fish preparations, often with ginger, scallions, and soy-based sauces. The fish works well with light sauces, citrus, herbs like dill and tarragon, and delicate aromatics. Due to its lean nature, it benefits from added fat through butter, olive oil, or cream-based preparations. Flounder is also suitable for poaching in court-bouillon or white wine.
