I made these into little tartlets for a party appetizer. I cut the pie crust into little circles with a cookie cutter, and pressed them into my muffin pan. I put the sauteed onions in the cups and poured the egg to about half-full. I put the crumbled bacon on top before baking. They were really delicious. Everybody asked for the recipe.

I ended up melting the butter separate and whisking it with the eggs. I used 5 eggs and could have used 6. If I make it again I will add it bacon in the egg mixture. I also added some leftover fondue cheese I had in the fridge. This recipe has the potential to be excellent but it needs improvement.

I made this tart for two people - both of whom had never eaten an onion tart. Each said it tasted good and wasn't too onion-y as one might expect from eating a bunch of onions in a pie crust. (Even my three-year-old ate a sizeable piece of this.) One commented that he might like to have more bacon in the recipe (but that might be because was was inclined toward more meat in a dish). As for the recipe, I was concerned that there wasn't enough egg (I think I was expecting something more quiche-like), but in the end, everything seemed to go together quite well - meaning this recipe works. If you like onion tart, I think this recipe will suit you.

Very tasty but a more work than the recipe implies. Between frying the bacon, sauteeing the onions (you will want them almost carmelized, so it takes around 30 minutes), pre-baking the shell and everything, this recipe takes a few hours. The first time I made this, I took one of the previous reviwers suggestions and cut the pie crusts into little tartlets and pressed into muffin pans. If you do this, use non-stick spray, as 1/2 of mine broke apart trying to extract them from the pan. I also used one extra egg since mine were very small, but I think you should stick to 2 small eggs or the tart won't be flat enough. (It is not supposed to be fluffy like a quiche.) And I wasn't sure how much of the mixture to put in the shell either; I'm guessing 1/2 full. Also, if you don't want your pie shell to be too moist/soft, prick the shell on the sides and bottom before baking, and brush a light egg wash on before pre-cooking it. Finally, I suggest slicing your onions very thin, and use the sweet yellow variety.

This was amazingly easy and tasty. I had 2 bunches of leeks I needed to get rid of, so I used them as well. This one's a keeper.

i was told how to make this tart except the one change was to use a variety of onions--red, sweet, green, shallot, leek etc---and to always make sure to include a sweet onion--also to add a little shredded cheese--swiss or parmasan would be good i think

Delicious, simple, and quick! I used Walla Walla sweet onions, and sauteed them until they were caramelized. I left off the bacon, but next time, I think I'll make a bacon and mushroom topping to put on after the pie is baked, for those who want it.
