  1. Preheat oven to 400 degrees F (200 degrees C).
  2. Place the bacon into a skillet, and cook over medium heat until browned. Remove bacon from skillet, reserving 4 tablespoons bacon fat, and drain on paper towels.
  3. Place the onions into the same skillet with the bacon fat, and cook over medium-high heat until evenly browned, about 8 minutes. Season with salt and pepper. Combine the milk and cream in a bowl. Sprinkle the flour over the onions, and stir to blend. Stir in the milk mixture. Cook and stir over medium heat until the mixture thickens. Remove from heat, stir in the bacon, and set aside to cool 10 minutes.
  4. Beat the eggs in a mixing bowl until light colored and frothy. Stir a spoonful of the onion mixture into the eggs. Add another spoonful of the onion mixture, and continue stirring. Repeat, until all the onions have been stirred into the eggs and are thoroughly blended. Pour the mixture into the prepared pie shell. Sprinkle with nutmeg.
  5. Bake in preheated oven until the crust is lightly browned, about 20 minutes. Remove from the oven and cool 5 minutes before serving.

I am the author of this recipe and I gave it 5 stars on behalf of my family, coworkers and friends that ask for this dish at almost every potluck.

We just finished eating this for supper with corn on the cob, it was super good! I didn't use bacon because we didn't have any. Funny thing is that without even saying anything, my husband said ...

This was amazing. My super picky 12 year old daughter loved it and even my 2 year old ate a piece. I don't think I could fit 5 onions in one pie shell though since Idaho has some really big o...

We liked this, but each one of us thought something about it could be improved! One didn't care for the bacon with the onions, one thought it needed more herbs to flavor it, one thought we shou...

Had this in France ~16 years ago. I didn't like onions then... I had a second helping. I wanted to introduce my wife to it (now that I've come to my senses on onions). This seems to be the clo...

I see I'm the only one whose tart came out a bit too watery. I think I used onions that were too large, and next time, I would saute them longer - perhaps caramelize them. It did taste great, ...
