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.


  1. Preheat the oven to 180ºC
  2. Peel and chop the onions. (pro tipp: use protective glasses!) Mix the eggs and set aside.
  3. 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)
  4. 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.
  5. 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!)
  6. 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.

A woman on a mission!

Agathe looks for and accompanies French producers who want to sell their products in a fairer way. Finding typical French products, tasting them and convincing farmers to join the movement animates Agathe’s every day. More personally, she tries to enjoy a "simpler life", prioritizing good moments shared over a life of material consumption.
