Trout Mancy with Lemon Butter Sauce

Trout Mancy (or meuniere-style) is where Louisiana seafood meets French kitchen technique. Flour-dredged trout fillets sauteed golden in butter, then topped with a pound of crawfish tails and briny capers, the whole thing finished with a lemon butter sauce built right in the pan.

The trout cooks fast, just 4 minutes per side. The flour coating gives it a thin, golden crust that protects the delicate flesh and creates the fond that flavors the sauce. Once the fish is on the warm platter, the crawfish and capers go into those buttery drippings for a quick saute. The residual heat warms the crawfish through without overcooking the tender tails.

The lemon butter sauce is a classic beurre blanc technique. A little flour, beef stock, and lemon juice go into the pan, whisked together over heat until thickened. Then the pan comes off the burner and cold butter gets whisked in, a bit at a time. Adding butter off-heat is critical. Too much heat breaks the emulsion and you get a greasy, split mess instead of a smooth, glossy sauce.

Straining the sauce before serving removes any flour lumps and gives you a clean, silky pour over the fish.

Chef Tips

• Use cold butter for the sauce and whisk constantly as it melts. Cold butter emulsifies smoothly. Room temperature butter melts too fast and separates.
• Veal stock gives the sauce a richer body than beef stock because of its higher gelatin content. Use it if you can find it.
• Don’t overcrowd the pan when sauteing the trout. Cook one fillet at a time so each piece gets proper contact with the hot surface.

Variations

• Use shrimp instead of crawfish if crawfish tails aren’t available.
• Add a splash of white wine to the pan before the stock for extra depth and acidity.
• Garnish with fresh parsley and thin lemon slices for a classic presentation.
