Mussels Baked in Mornay Sauce

by Editorial Staff

If you want to surprise your guests with something unusual and tasty, cook mussels with mornay sauce, or rather mornay. This is a French sauce with yolks and cheese based on béchamel sauce. Seafood is baked with a creamy cheese sauce in portion forms. A worthy alternative to the usual julienne.

Mussels Baked in Mornay Sauce Instructions

  1. Melt 20 g butter in a saucepan over medium heat. Add 1 tbsp wheat flour and whisk constantly for 1 minute to form a smooth paste without lumps.
  2. Gradually add 100 ml cream while whisking continuously to create a smooth sauce.
  3. Remove from heat and whisk in 1 egg yolk until fully combined.
  4. Add 70 g grated hard cheese and whisk until the cheese is melted and the sauce is smooth.
  5. Season the sauce to taste with salt and pepper (note that cheese is naturally salty, so taste first before adding more). Grate 10 g nutmeg into the sauce and whisk well.

  7. Pour the Mornay sauce over the mussels and optionally sprinkle a pinch of paprika flakes on top.
