How to use peeled boiled crawfish as a steak topper?

Sautee down in some butter, onion, and garlic. Super easy.

Or fold them into a Mornay sauce. That wouldn't suck.

pontchartrain sauce

Heat a skillet and add 2 tablespoons of butter and 2 tablespoons of EVOO , and blackening seasoning

add sliced mushrooms, chopped onions and minced garlic. Cook down until onions transluscent. De-glaze with white wine

add heavy cream and reduce until sauce thickens. Add crawfish tails then top with green onions and chopped parsley

add another tablespoon of butter , stir well and serve over steak, fish , etc ....

You can also sub shrimp for crawfish , capers cal be added if you wish

do a search for Alexander sauce like Papadeaux makes. I would give it out but I don't have the recipe in front of me. Great on fish, haven't tried it on steak yet but it should be awesome.
