Just that!
Saw a tip online saying "spread a thin layer of tomato sauce onto the bottom of the dish so the pasta doesn't stick".... 🫨
In 30 years of making lasagne I've never put a floor in & curious as to whether I've been missing out all this time 😅
(To the point I've just made the sauce and may experiment, but wondered if I've been committing a misdemeanour this whole time. Sorry Italians if I have!)
