# Expert Tips:

01 -
  • Everything cooks in a single skillet, so the kitchen stays tidy and you get more time to relax.
  • The blend of ham, Swiss, and veggies is satisfying enough for dinner, yet light enough for brunch or meal prep.
02 -
  • If you rush and try to cut the frittata right when it’s hot, it may crumble and lose its shape—patience pays off.
  • Greasing the skillet well with olive oil helps avoid sticky disasters and makes serving a breeze.
03 -

  • Layer cheese both in the eggs and on top for a golden crust that seals in moisture.
