→ For Cooking

11 - 1 tablespoon olive oil

# Directions:

01 - Preheat oven to 375°F.
02 - In a large oven-safe skillet, heat olive oil over medium heat. Add diced onion and sauté for 3 minutes until translucent.
03 - Add diced cooked ham to the skillet and cook for 2 minutes. Stir in chopped spinach and halved cherry tomatoes and cook until the spinach is wilted, about 1 minute.
04 - In a mixing bowl, whisk together eggs, whole milk, salt, black pepper, and dried thyme. Stir in half of the shredded Swiss cheese.
05 - Pour the egg mixture evenly over the ham and vegetables in the skillet. Sprinkle the remaining Swiss cheese on top.
06 - Cook on the stovetop for 2 to 3 minutes until the edges begin to set.
07 - Transfer the skillet to the preheated oven and bake for 12 to 15 minutes, or until the frittata is puffed and set in the center.
08 - Remove the skillet from the oven, let cool for several minutes, slice, and serve warm or at room temperature.

# Expert Tips:

01 -
  • Cleanup is as quick as chopping the last tomato—everything happens in one pan.
  • The frittata reheats beautifully, so tomorrow’s lunch quietly sorts itself out.
02 -
  • If you rush the stovetop step, you’ll get undercooked eggs along the edges, making slicing messy.
  • Adding the cheese in two layers (half in, half on top) is the little trick that stops the frittata from drying out.
03 -
  • Let the eggs come to room temperature before mixing for a fluffier, lighter texture.
  • Grate the cheese fresh off the block for the best melt—you’ll taste the difference.
