Louisiana Remoulade Sauce is my go-to secret for turning simple seafood and veggies into something special. This creamy, zesty condiment has roots in Creole cuisine and instantly elevates crab cakes po boys shrimp or even roasted potatoes. It is a classic that I fell in love with during a trip to New Orleans and since then I always keep a batch ready in my fridge for impromptu gatherings or easy weeknight dinners. The blend of bold flavors and creamy texture captures that Southern spirit in every spoonful.
I first made this sauce to dress up some leftover fried shrimp and ended up eating it straight from the bowl—yes it is that addictive.
