# Expert Tips:

01 -
  • They transform ordinary leftover croissants into something that feels like a weekend brunch in Paris
  • The mustard and mayonnaise create this creamy, tangy binder that keeps everything perfectly moist
02 -
  • Dont overstuff the croissants or the filling will spill out during baking and make a mess of your pan
  • Let them cool for just a couple of minutes before eating because the cheese gets insanely hot
03 -
  • If your croissants are super fresh, toast them lightly for 5 minutes before slicing so they do not get soggy
  • Room temperature ingredients blend together better than cold ones from the fridge
