1

Preheat the oven to 400 degrees F (200 degrees C).
2

Put the bacon in a skillet and cook over medium heat until browned. Remove the bacon from the skillet, reserving 4 tablespoons of bacon fat, and drain it on paper towels.
3

Add the onions to the same skillet with the bacon fat and cook over medium-high heat until evenly browned, about 8 minutes.
4

Season with salt and pepper. Mix the milk and cream in a bowl. Sprinkle the flour over the onions and stir to combine. Stir in the milk mixture. Cook and stir over medium heat until the mixture thickens. Remove from the heat, stir in the bacon, and let cool for 10 minutes.
5

Beat the eggs in a mixing bowl until pale and frothy.
6

Stir a spoonful of the onion mixture into the eggs. Add another spoonful and keep stirring. Repeat until all the onions are stirred into the eggs and fully blended.
7

Pour the mixture into the prepared pie shell and sprinkle with nutmeg.
8

Bake in the preheated oven until the crust is lightly browned, about 20 minutes.
9

Remove from the oven and let cool for 5 minutes before serving.
