When I made this, my kids asked for seconds. This recipe is going to be a regular go-to for us

1. Preheat oven to 375°F (190°C).
2. Roll out the pie crust and fit it into a 9-inch pie dish. Trim the edges if needed and prick the bottom with a fork. Bake the crust for 8-10 minutes, until lightly golden. Remove from oven and set aside.
3. In a large bowl, whisk together the eggs, heavy cream, whole milk, salt, pepper, and nutmeg until well combined.
4. Stir in the grated Gruyere cheese, Swiss cheese, and cheddar cheese until evenly distributed.
5. Pour the egg mixture into the prebaked pie crust.
6. Bake the quiche in the preheated oven for 30-35 minutes, or until the filling is set and the top is lightly golden.
7. Remove the quiche from the oven and let it cool for 5-10 minutes before slicing and serving.
