# Expert Tips:

01 -
  • Everything cooks in one pan so dinner comes together fast and the sink stays almost empty
  • The combination of ham and Swiss gives a nutty savory depth that works any time of day
02 -
  • Cooking the onions until translucent is a small step that rewards you with sweet depth
  • Letting the skillet rest for a few minutes after baking keeps the slices from falling apart
03 -
  • Bring eggs to room temperature for a smoother custard and even cooking
  • Use an oven safe skillet sized ten to twelve inches so the frittata cooks through without being too thick
