Ingredients
Method
- Preheat broiler with a rack 6 inches from the element. Heat olive oil in a 10-inch oven-safe nonstick skillet over medium heat. Add potatoes in a single layer and cook 6 minutes, until golden underneath.
- Flip potatoes, add onion, salt, and pepper. Cook 4 minutes, stirring occasionally, until softened.
- Whisk eggs, milk, a pinch of salt, pepper, and half the Parmesan until pale and frothy. Melt butter in the skillet, pour in the egg mixture, and scatter remaining Parmesan on top. Cook 2 to 3 minutes until edges set.
- Broil 2 to 3 minutes until puffed and golden brown. Let rest 1 minute, then slice, garnish with parsley, and serve.
Notes
Let the frittata rest for a minute before slicing; it firms up and slides out of the pan more easily. Use a nonstick skillet to prevent sticking, and wrap the handle in foil if it’s not broiler-safe.
