# Expert Hints:

01 -
  • Cleanup is a breeze, since everything happens in just one pan.
  • You can swap veggies or cheeses to suit whatever's in your fridge.
02 -
  • Using a cold skillet can cause sticking, so heat it well before adding anything.
  • Letting the frittata rest briefly after baking makes slicing neater and avoids a soggy mess.
03 -
  • Always preheat your skillet before adding vegetables or eggs for a perfectly set base.
  • Layering cheese twice – inside and on top – creates a melty, irresistible finish.
