Heritage Tomato Upside-Down Tart
A thick layer of sweet, delicious, mixed heritage tomatoes, cooked with a touch of red onion, a splash of olive oil and balsamic vinegar, all finished with a layer of buttery, crispy puff pastry. Cooking the tart this way ensures all the flavours and juices stay within the tart and do not evaporate away. Furthermore, it guarantees a crispy pastry top, which when inverted becomes a crispy pastry base – no soggy bottoms when cooked this way! Finish with your favourite toppings – I added a luxurious, creamy burrata, some rocket leaves and extra balsamic – to add contrasting flavours, textures and utter lusciousness.
Upside-down savoury and sweet tarts have been all the rage on insta and tick tock for a while now, so I thought it was about time I tried it out. I was not disappointed. Super quick, easy and bursting with flavour, this tart makes a speedy and healthy lunch and is enough for 2 hungry people but could stretch to 4 with some sides
How to make Heritage Tomato Upside-Down Tart
Collect all your ingredients together:
- drizzle of olive oil
- drizzle of balsamic vinegar
- freshly ground sea salt and black pepper
- red onion, finely sliced
- fresh tomatoes, sliced – I like to used a mix of colours
- ready rolled puff pastry, shop bought or homemade – I use shop bought
- egg wash
Topping suggestions:
- rocket or basil leaves
- fresh burrata or mozzarella ball
- parmesan shavings
- black or green olives
- extra balsamic vinegar
How to make this super quick tart:
- Drizzle some olive oil and balsamic vinegar on the base of the pan in an area roughly the size of the pastry. Grind over some sea salt and black pepper.
- Scatter over some finely sliced red onion, to taste.
- Layer over the tomatoes and grind over a little more salt and black pepper.
- Check the pastry is large enough to cover the tomatoes and if not, roll out slightly to ensure it is the correct size.
- Lay the pastry over the tomatoes, pressing the edges down onto the baking tray with a fork. Brush with egg wash.
- Bake in the centre of a preheated oven for 20 – 30 minutes or until the pastry is light brown and crispy.
- Leave to sit for a few minutes before carefully draining off any juices. Save these to pour over the tart before you serve.
- Invert the tart onto a serving plate. Either serve as is or finish with your chosen toppings.
