# Expert Advice:

01 -
  • Its the kind of dinner that makes everyone lean in a little closer when they walk through the door, drawn by that incredible baked pasta aroma that fills the whole house
  • The sauce comes together in minutes and tastes so indulgent that nobody will believe its lactose-free
02 -
  • The first time I made this, I skipped the flour in the sauce and ended up with a disappointing, runny mess that never thickened properly
  • Letting the dish rest for those five minutes after baking feels impossible when you are hungry, but cutting into it too early makes everything slide apart on the plate
03 -
  • Grate your own lactose-free cheese if possible, because pre-grated varieties contain anti-caking agents that prevent proper melting
  • Use gluten-free flour and pasta to make this completely friendly to multiple dietary restrictions without sacrificing any comfort
