The Ultimate Onion Tart Recipe
French comfort food starring caramelized onions
If there ever was a perfect dish for me, it would be onion tart. It's comforting, easy and inexpensive to prepare, filling and always better the next day. Onion tart is also my go-to dish for winter dinner parties, and this recipe that I learned in Normandy always ends up being a huge hit. The entire thing takes an hour from start to finish and your guests will be impressed. Think of onion tart like onion soup, but with a crust. Or quiche, but better. Life just got a little sweeter.

- Preheat the oven to 375F. Melt the butter and oil together in a large skillet and add the diced bacon. Cook until the bacon is halfway cooked.
- Add the thyme, onion and salt to the skillet. Cook on medium-low heat until the onions are completely translucent and caramelized. This will take around 30 minutes. Remove from heat and allow to cool slightly.
- Combine 2 eggs and the half and half in a bowl. Add the caramelized onion mixture and the freshly ground black pepper.
- Roll out the puff pastry in a buttered pie or glass dish. (Make sure the pastry has four edges in order to hold the onion mixture.)
- Add the mixture to the pastry and bake for 35 minutes or until the crust and top are slightly browned.
- Allow to cool, then slice and serve.
