Agathe’s French onion tart recipe
Sometimes tasty food can be surprisingly simple and easy to make!
Case in point: this French onion tart. Those two words may not sound like they go together, but trust us, it tastes surprisingly good !
Onion tart is actually quite a staple of French cuisine, especially at this time of the year. It is the “go to” autumnal recipe of our French “Farmer Hunter” Agathe, when she needs to cook a quick but ‘fancy’ meal, serving as either a starter to your dinner party or as a main course for a light lunch (or in whatever other setting!). The key is using the right onions: aromatic and high quality.

Instructions:
- Preheat the oven to 180ºC
- Peel and chop the onions. (pro tipp: use protective glasses!) Mix the eggs and set aside.
- Place the puff pastry in a buttered tart pan (or, if you are using the ready-made one like us, you can also leave on the paper to keep it from sticking to the pan)
- Pour the olive oil and onions into a frying pan and cook for about 10 minutes on a medium heat, stirring from time to time.
- Once the onions have browned, turn off the heat, add the crème fraîche, the 2 mixed eggs, salt and pepper (feel free to add more spice if you like!)
- Pour the onion mixture over the pastry, bending the corners on top (as pictured) and bake in the preheated oven at 180 degrees for 30 minutes.

Enjoy!
