# Additional Tips::

01 -
  • The red lentils break down beautifully creating this incredibly rich texture that mimics a slow cooked meat sauce without any actual meat
  • You literally dirty one pan from start to finish which means you can spend more time eating and less time scrubbing baked on cheese
  • The smoky paprika and balsamic vinegar give it this complexity that makes people think you spent hours over the stove
02 -
  • I once forgot to cover the pan while baking and the top layer of pasta stayed completely crunchy
  • The resting period is absolutely crucial even if everyone is already at the table begging to eat
  • Dont be tempted to skip the no boil pasta sheets regular ones simply wont cook properly in this method
03 -
  • If your pan is very deep check that your oven rack is low enough to fit it comfortably
  • Room temperature ricotta spreads much more evenly than cold straight from the fridge
  • Use the back of a spoon to gently press down each layer as you go
