# Expert Tips:

01 -
  • Cleanup is basically one pan, so you spend more time eating and less time scrubbing.
  • The mix of ham, Swiss, and veggies makes every bite both hearty and fresh, so it never feels boring.
02 -
  • Trying to rush the stovetop step means your frittata might stick or burn; patience pays off.
  • Chopping spinach at the last second just before adding keeps the greens bright and lively.
03 -
  • Bringing eggs to room temperature before whisking makes the frittata puffier and more tender.
  • Bake in the upper third of your oven for a golden brown top—the secret to eye-catching slices.
