Test Kitchen Notes
This tart wound up being so savory and delicious, with a beautiful flaky crust. In a long rectangular shape, it's a real showstopper too! The recipe worked especially well by using a combination of butter and olive oil to cook the onions and bacon, and was further improved by the use of fresh herbs. The filling made three cups' worth, which filled the tart perfectly, and became nice and golden in the oven. There was no shrinkage of the pastry and it became really nice and flaky. I loved the combination of the sweet onions, salty bacon, and herbs, and the tart was so stunning to look at that I would definitely make this again. —Jennifer Philipp
