Balsamic Caramelized Onion Filo Tart with Camembetter

This filo tart is a perfect snack when friends are over or as a lunch if you have a little bit more time on your hands. The complexity of the caramelized onions together with the creaminess of Camembetter make this a perfect combo. Give it a try! 


🕒25-30 min         👤Ideal to share with 2-3 people 



  • 4 squares of (plant-based) filo dough
  • 1 tablespoon olive oil
  • 3 onions (we used red onions)
  • 1-2 tablespoons balsamic vinegar
  • Camembetter
  • Salt and pepper to taste
  • optional: Thyme (without stem), Walnuts (roughly chopped)



  1. Preheat your oven at 200 °C 
  2. Take the filo dough out of the freezer and let them defrost (takes about 5 min) 
  3. In the meanwhile, cut the onions to slices. 
  4. (also watch step 5) Caramelize the onions: Heat a pan to medium heat and add olive oil and onions, fry them slowly, stirring frequently. When you feel the mixture gets too dry - add 1-2 tablespoons of water. And continue this for approx 10 min. You want the onions to get golden brown and soft. Then turn off the eat and add balsamic vinegar (1-2 tablespoons depending on size of the onions and how much you love balsamic ;) )  See the picture for what it should look like. 
  5. While the onions are caramelizing, line a baking tray with parchment paper, take the paper of each filo and stick the 4 squares of filo dough together (if they don't stick, add a drop of water around the edges where you stick them together). Add to the oven and bake for approx 5 min (This step is to 'prep' the dough, as your toppings are already baked). 
  6. When onions are caramelized and filo dough is light brown, take filo out of the oven and top with your onions. Put back into the oven for 10-15 minutes until filo dough is puffed and golden brown. 
  7. In the 3 final minutes, add slices of Camembetter and thyme. 
  8. Take your tart out of the oven and add walnuts.
