# Directions:

01 - Set the oven to 375°F (190°C) and allow it to preheat.

04 - In a mixing bowl, whisk together eggs, whole milk, salt, black pepper, and thyme. Incorporate half of the shredded Swiss cheese.
05 - Pour the egg mixture evenly over ham and vegetables in the skillet. Sprinkle remaining Swiss cheese over the surface.
06 - Cook skillet on the stovetop for 2–3 minutes, allowing edges to begin setting.
07 - Transfer skillet to the preheated oven. Bake for 12–15 minutes, until puffed and fully set in the center.
08 - Remove from oven. Let rest for several minutes, slice, and serve warm or at room temperature.

# Expert Suggestions:

01 -
  • This frittata sneaks loads of veggies and protein into a single, satisfying slice.
  • The one-pan approach means less fuss and fewer dishes, perfect for lazy evenings.
02 -
  • Once, I forgot to use an oven-safe skillet and the handle melted—a lesson in always double-checking your cookware before baking.
  • Letting the frittata rest for a few minutes after baking keeps it from falling apart when slicing.
03 -
  • Don’t rush the initial stovetop setting—the edges need to firm up or you’ll have runny slices.
  • Mix cheese throughout instead of only topping; it guarantees melty bites in every forkful.
