French Quiche Lorraine with Spinach and Gruyère - Baked in a Cast Iron Skillet

Method

1. Preheat oven to 375°F (190°C) and place a 10-inch cast iron skillet inside to heat.
2. In a food processor, combine flour and cold butter until crumbly. Add ice water and pulse until dough forms.
3. Roll out dough and fit it into the hot cast iron skillet, pressing it against the sides. Trim excess dough and prick the bottom with a fork.
4. In a bowl, whisk eggs, milk, and salt. Stir in Gruyère cheese, cooked bacon, and sautéed spinach.
5. Pour mixture into the crust and bake for 25-30 minutes until set, checking for doneness with a toothpick.
