# Expert Hints:

01 -
  • You can cook and clean up with just one pan—making weeknight cooking feel effortless.
  • The flavors are cozy, but you can swap veggies or cheeses for endless variety.
02 -
  • If you skip wilting the spinach before pouring in the eggs, the frittata can turn watery.
  • Letting the frittata cool for a few minutes makes slicing cleaner and prevents it from falling apart.
03 -
  • Always whisk eggs until airy for the fluffiest texture.
  • Sprinkle cheese on top just before baking for the golden crust that everyone fights over.
