  • The Bechamel de Poisson is now ready to be used in your seafood dishes. Pour it over grilled fish fillets, use it as a base for seafood lasagna, or incorporate it into fish pies for a creamy and flavorful filling.


If you prefer a smoother sauce, you can use an immersion blender or regular blender to blend the sauce until smooth after straining.
Feel free to add additional herbs or spices to customize the flavor of the Bechamel de Poisson. Fresh herbs such as dill or chives can add a vibrant touch.
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop, whisking occasionally, until warmed through.
