The Field Method for Cast Iron Care
Instructions
Preheat the oven to 350°F. In a large bowl, combine the eggs with the milk, salt, and pepper to taste. Whisk just until no visible egg whites remain.
In a No.8 Field Skillet, heat the olive oil over medium heat. Add the onions and cook, stirring frequently, until softened, about 5 minutes. Pour the egg mixture over the onions and add the shredded cheese (if using) and any mix-ins. Stir until well combined. If using crumbled goat cheese or feta; sprinkle evenly over the top.
Cook the egg mixture, without stirring, until the edges are set and just begin to pull away from the side of the skillet, about 7 minutes.
Transfer the skillet to the oven and bake until the eggs are just set (they should barely jiggle when you shake the pan), 15 to 20 minutes.
Let the frittata cool for at least 10 minutes before slicing and serving. The frittata can be made an hour or two ahead of time; reheat (if needed) in a 250°F oven.
Seasoning Rating: Best
A well-cooked frittata will release easily from your skillet, and the initial glug of olive oil and full-pan coverage will help contribute seasoning to your cooking surface.

Better—The best way to keep your skillet in great shape is to cook frequently, and cast iron-friendly dishes like these are your bread and butter.
Safe—These recipes won't strip seasoning away from your pan, but won't really add any, either.
OK—Be sure to clean up promptly. Recipes with this rating might feature acidic ingredients which can affect seasoning if not washed soon after cooking.
