# Expert Pointers:

01 -
  • It makes a satisfying meal with little cleanup, perfect after a busy day.
  • You can easily swap or add veggies for a new twist each time.
02 -
  • If you rush and skip sautéing the onion, the frittata tastes sharp rather than sweet.
  • Adding half of the cheese to the eggs, instead of all on top, creates melt-in-your-mouth pockets throughout.

  • A little patience letting the skillet cool helps keep slices intact and beautiful.
