Start by cutting your puff pastry into several pieces, then spread a layer of Boursin cheese.

Add your slices of smoked salmon.

Brush your croissants with an egg yolk and a little milk.

I added poppy seeds, but you can use any seeds you like (such as sesame seeds…).

Bake your croissants at 350°F for about 30 minutes (depending on the cooking, if you think it's not cooked enough, you can extend the cooking time). Enjoy☺️
