Vegan Raw Caramelised Onion Tart

This Vegan Raw Caramelised Onion Tart is the slightly more in depth grown up cousin to our recipe for the Vegan SpringRaw Quiche. Where the Spring Quiche is more of an assembly job, this tart requires a separate making of the tart casing. This in turn makes this a slightly higher brow and textured recipe. The tart bases can also be used for any number of recipes (where you choose whatever filling you wish!).

It takes a few days of dehydration and preparation – so this Vegan Raw Caramelised Onion Tart recipe is definitely great for a special dinner party or occasion. But as I already mentioned, the tart casing can be used for any number of recipe and can even be adapted to be sweet if you add a little coconut sugar and cut the miso, salt and lemon in the recipe. So make a few extra and keep them in an airtight container in the fridge for future recipes. You will thank yourself later believe me!

Vegan Raw Caramelised Onion Tart

Vegan Raw Caramelised Onion Tart Ingredients (serves 4)

Base:

Tomatoes:

  • 200g cherry tomatoes (4 cherry tomatoes per tart)
  • 1 garlic clove
  • 8 sprigs thyme
  • ½ tsp salt & pepper
  • ½ tsp pepper

Caramelised Onion:

Filling:

  • 4 zucchini (courgettes) grated
  • 1 asparagus spear
  • 1 tsp ev olive oil to garnish

Vegan Raw Caramelised Onion Tart Method:

Base:

  • Put all of the ingredients into a blender and whiz until it reaches a super fine consistency.

Tomatoes:

  • Cut the cherry tomatoes in half and throw into a mixing bowl.
  • Cut the garlic as finely as possible (into a paste if possible) and throw into the mixing bowl with the rest of the ingredients. Mix them together thoroughly and leave to marinade while you prepare the other ingredients.

Caramelized Onion:

  • Cut the red onion into thin rings and add salt to extract juices. Mix the coconut sugar with a little warm water to turn into a paste (you can also use coconut nectar here) and add to the onions. You can be quite rough and even squeeze the onion a little. You will notice that the nectary juices will start coming out – this is what you will use to baste the quiche later.

Filling:

  • Grate the zucchini and then take handfuls and squeeze the juices/water out into the sink. Do this as hard as you can.

Assembly:

  • Now pour some more of the cashew base mixture, starting around the sides of the time where the ‘crust’ will be and then over the tomatoes, onion and zucchini filling.
  • Next put a few rings of the caramelized onion on top of the zucchini and then place four of the cherry tomato halves (along with some of the thyme and garlic) evenly on top of the zucchini and onion.
  • The zucchini should be a dome in the middle of the tart tin that reaches just under the height of the tart tin sides. It is ok to have more filling in the middle, as this will sag a little when once dehydrated.
  • Pour a little of the cashew base into the bottom of an 11cm non-stick tart case so that the bottom is covered in about ½ cm of mixture.
  • Grab 2/3 of the grated and squeezed zucchini and divide into 4 and place into the middle of the tin. Placement is important here so you will have a ‘crust’ of cashew base around the edge, which will not only make the dish look nice, but will add extra texture and crunch once dehydrated.
  • The mixture will now have nearly filled the tart tin to the top with a bulge in the middle. You can bang the tart cases on the bench to to even it out – or use you hands or a spatula to do this if this work better for you.
  • Now place some more rings of onion in the middle of the quiche again leaving space around the edges. Place another four cherry tomato halves (along with the thyme and garlic) and then put the asparagus spear (cut to length) in the center.
  • Spoon over a tablespoon or two of the caramelized onion juice over each quiche and then drizzle with a little olive oil.
  • Place in a dehydrator at 45°C for 24 hours before removing from the non-stick tart tin to dehydrate further and flipping the quiche upside down to dehydrate for a further 24 hours.
  • You can then flip the quiche the right way up and dehydrate from anything up to a couple of hours to another 24 hours until the quiche has firmed up. The time that you dehydrate may vary a lot. Just press lightly with you finger to see if it has firmed up in the middle to see if it is done. You do want it to be a little gooey in the middle.
  • You can use your oven set on its lowest temp to do this if you don’t have a dehydrator.
