# Expert Suggestions:

01 -
  • This frittata makes weeknight clean-up a breeze, as everything cooks in a single pan.
  • The mingling flavors of creamy eggs, savory ham, and melting Swiss cheese are always satisfying.
02 -
  • Don’t rush the sauté—if the onions aren’t translucent, your frittata won’t have that subtle sweetness.
  • Cooking directly on the stovetop before baking prevents soggy bottoms; I learned this after a few failed attempts.
03 -
  • Preheating the skillet with oil helps prevent sticking and enhances flavor.
  • Mixing in cheese before pouring the eggs gives those luxurious melted pockets in every bite.
