Tips:

  • Choose the right onions: Use medium-sized yellow or white onions for a balance of flavor and texture.
  • Slice the onions evenly: This will ensure that they cook evenly and create a uniform gratin.
  • Cook the onions slowly: Low and slow cooking will caramelize the onions and bring out their natural sweetness.
  • Use a good quality cheese: Opt for a cheese that melts well and has a strong flavor, such as Gruyère, Parmesan, or Cheddar.
  • Don't overcook the gratin: The onions should be tender but still have a slight crunch. Overcooking will make them mushy.
