So, you guys know that I’m happily married, right? But let me tell you, if I could marry a food item, my husband would be out on the street and this beautiful little round of grain-free deliciousness would be my one true love.

I’m not going to lie, it’s a little bit fiddly, but only a little bit I promise. The creaminess of the filling, against the sweet of the onion and the tang of the goat’s cheese is just perfection.

Try it, tell me that you wouldn’t spend the rest of your life with it. Enjoy!

Ingredients (makes 4 small or 1 large tart)

Crust:
  • 1 cup almond flour (100 g/ 3.5 oz)
  • 1 cup + 2 tbsp finely grated Parmesan cheese (100 g/ 3.5 oz)
  • 2 large egg whites (reserve yolks for filling)
  • pinch of sea salt
Filling:
  • 2 small red onions, sliced (120 g/ 4.2 oz)
  • 2 tbsp extra virgin olive oil (30 ml)
  • 1 tbsp balsamic vinegar (15 ml)
  • 2 tbsp Swerve or Erythritol (20 g/ 0.7 oz)
  • 2 large eggs
  • 2 large yolks
  • 3/4 cup heavy whipping cream (180 ml/ 6 fl oz)
  • pinch of salt and pepper
  • pinch of nutmeg
  • 1 pack soft goat’s cheese (200 g/ 7.1 oz)
  • 1/2 tsp fresh thyme, with extra for garnish

Instructions

  1. Thinly slice the red onions.

  2. Heat the olive oil in a frying pan and add the onions. Cook over med-high heat until the onions start to soften. You don’t want to brown them, you just want them soft.

  3. Add the balsamic vinegar, the Swerve and the thyme and reduce heat to medium-low. Cook, stirring occasionally, until the onions are reduced down into a rich, sweet base.

  4. Meanwhile, preheat oven to 170 °C/ 340 °F (fan assisted), or 190 °C/ 375 °F (conventional). Place all crust ingredients into a bowl and combine well into a dough. Spray four individual tart tins, or one large tin, with olive oil. Note that this dough can be a bit sticky with cooked, so spray tins well.
  5. Divide the dough between 6 mini tart pans (12 cm /5 inch each) and press out into the tins evenly, taking the time to make sure it is firm and even. Prick the bases with a fork and then place in the oven for 10 minutes. Sit aside to cool once they’re done and reduce the oven temp to 160 °C/ 320 °F (fan assisted), or 180 °C/ 355 °F (conventional).

  8. Slice the goat’s cheese into even rounds and place on top of the onions.

This recipe is the bomb! I love the flavors, and will definitely make this again regularly. I am also planning on using the base for other tarts, it holds together very well.

Suggestions for reheating smaller tarts?

Reply

You could reheat them in the oven (I'd say 150 C/ 300 F for about 3 minutes) or in a microwave oven.

Hi Naomii,

Thanks,
Vanessa

Why can I no longer PRINT your recipes.....It was always a great pain to have to rearrange and rescale to fit fewer pages but now it is impossible. I have tried several ways and since this particular Cook' recipes are being shown, I get blanks or the whole web site.....Big bother to have to totally retype or try highlighting small sections and pasting....ugh....

Bettie, you can print all the recipes. We actually improved this feature and optimised for space so it no longer takes too many pages - mostly it fits on 1. You can find it right below the list of ingredients (see the options for printing and downloading). I hope this helps!
