Total Time: 1 hr 20 mins
Servings: 10
Yield: 10 servings

Ingredients

  1. 10 slices bacon, cut into 1 inch pieces
  2. 5 onions, thinly sliced
  3. 1 teaspoon salt
  4. ⅛ teaspoon freshly ground black pepper
  5. ½ cup milk
  6. ½ cup heavy cream
  7. 1 tablespoon all-purpose flour
  8. 4 eggs
  9. 1 pinch ground nutmeg
  10. 1 (9 inch) unbaked pie crust

Instructions

  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.

This was a simple recipe that really tasted great and I made it exactly like the recipe. I was for a pot luck and it was finished off in record time!

I made the tarte as written, but used 4 onions, as a couple were rather large. I found that it didn’t solidify and wasn’t seasoned enough, but otherwise was delicious. I may try it again with another egg and add some more nutmeg, salt and pepper.

Delicious Tarte a l’Oignon! Used about five carmelized onions, 2 eggs+3 egg yolks (used the whites for chocolate pavlova!), a shot of balsamic vinegar, 1t Nature’s Seasoning Salt and a tad bit more milk than double cream. Left off the pepper and bacon (like others did), sprinkled with fresh chives and baked til golden brown. Restaurant quality!

My family, coworkers and friends ask for this dish at almost every potluck or holiday event. PS: I always use yellow(brown) onions as they are sweeter, never white or red. —- Update I love seeing how everyone is finding ways to make it that suits their families and pantry, how creative. Bon appétit!

This was delicious! The only change I made was that I used 2 vidalia onions and 1 large regular onion and it was the perfect amount. It’s a keeper!

Excellent, easy recreation of my favorite patisserie lunch when I was a broke student in Paris. Pre-made crust was fine but homemade croissant pastry crust baked in individual mini quiche pans…SUPERB!
Kenneth Allison
Very, very tasty!! I substituted pre-baked tart shells, skipped the nutmeg (didn’t have any) and used 1 c. of half and half instead of the milk and heavy cream. Thank you for your delicious recipe.

My dad asks for this every year around the holidays. I find it is easier to make two but I don’t double the milk and cream, it is only a 30% increase, but doubling the flour is important as well as the increased cooking time. Additionally I sprinkle nutmeg in the bottom of the crusts, don’t pre bake the crusts, cover the crust edges with foil for 75% of the cook time and add bacon crumbs on top at the end after cooking.

Be sure to use the regular pie crusts. Not the deep ones. I found it set faster while cooking also the recipe made two tarts this way. The addition of balsamic was pure magic. I also crumbled the bacon which helped permeate the entire tart without a lot of chewing. I will definitely make this again!!

Everyone was hesitant and didn’t think they would like this when I told them I was making it for Christmas Eve dinner. They were all surprised by how good it was and what a great taste it had! Thanks so much for the recipe, it was nice to try something different and for it to turn out well!

First of all, let me say that this onion pie is absolutely delicious. I made modifications because, after reading all the reviews and scrutinizing the recipe myself, I didn’t think all of the filling would fit into one regular 9″ pie crust. I used only 6 slices of bacon, 4 medium-size Vidalia onions, 3/4 cup of half and half and 3 jumbo eggs. Upon the suggestion of “reciprocipe,” I added lt. brown sugar and balsamic vinegar to the filling. I also decided to place a lattice crust on top to use up some dough scraps I had. I egg washed the strips and sprinkled them with a little coarse salt. The pie baked for a full 35 minutes before it was set and browned to my liking. I will be making this again.

Love this recipe! I follow it nearly exactly expect for not adding bacon and sometimes using milk instead of cream.
Samuel Johnson
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 it would have been even better if I put some bacon in… So note to self: make sure to add the bacon 🙂

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, though! Good with steaks!

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 closest recipe to what I recall. Was easy to cook and quite tasty.
James Cook
Great guideline recipe… I used 4 medium vidalias, 1 cup of half & half, generous amounts of salt, pepper, a splash of aged balsamic and a bit (like 2 teaspoons) of brown sugar, nutmeg as recommended, and thinly sliced bits of 1 precooked sausage. It generously filled 1 deep dish crust. This dish was delicious– savory and sweet at the same time and very moist and filling. Thank you Nadine

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 onions so I made 2 pies instead. It keeps really well in the fridge for about a week if you have any left overs. Overall, this is just an amazing recipe and I can’t wait to make it for company.
