Warming and Rich Buckwheat Quiche with Kabocha Squash and Soy Milk

This is an organic and delicious quiche made without any butter or heavy cream. The extravagant kabocha squash makes this fluffy and super yummy.

Ingredients: one 22-cm tart

For the tart crust:
Buckwheat (soba) flour
120 g
Cake flour
60 g
Olive oil
3 tablespoons
2 tablespoons
For the appareil:
Soy milk
150 ml
Salt and pepper
a small amount
For the fillings:
Kabocha squash
500 g
Half-strips of bacon
Vegetable oil
1 tablespoon


1. Prepare the tart crust. Combine the buckwheat flour and cake flour in a bowl and mix well with a whisk.
2. Mix in the beaten egg in two separate batches.
3. Stir in the olive oil.
4. When the dough becomes crumbly, add water and use a spatula to bring it all together.
5. Once the dough comes together, put it into a bag and chill it in the refrigerator for about 30 minutes.
6. Prepare the filling as the dough chills. Cut the kabocha squash into 5 mm slices.
7. Place the kabocha squash in a heatproof dish, cover with plastic wrap, and heat in the microwave for 4-5 minutes.
8. Thinly slice the onion.
9. Heat the oil in a frying pan and stir-fry the onions.
10. Thinly slice the bacon.
11. Once the onions have cooked through, add the bacon and stir-fry.
12. Add the microwaved kabocha squash and stir-fry until the moisture evaporates.
13. Once the ingredients have cooked through, transfer to a bowl and set aside to cool.
14. Remove the chilled dough from the refrigerator.
15. Cut the plastic bag open, leaving the dough inside. Cut open another plastic bag, then place it over the dough. With a rolling pin, roll out the dough over the plastic to prevent sticking. (You can also do this sandwiched between sheets of plastic wrap.)
16. Roll the dough to a size larger than your tart mold. Remove the top sheet of plastic and flip the dough over the mold.
17. Press the dough into the mold. Remove the other sheet of plastic and trim off the excess dough.
18. Bake for 15 minutes in an oven preheated to 210°C.
19. To prepare the appareil, beat the eggs.
20. Beat them well.
21. Add the soy milk, salt, and pepper, and combine evenly.
22. Once the crust as baked, fill with the fillings.
23. Once filled, pour the appareil on top. Lastly, top with the cheese.
24. Bake for 30 minutes in an oven preheated to 180°C, and it's done!
25. It will be easier to cut once it cools.
26. Once cooled, it will be easy to remove from the mold. When serving from the following day onward, wrap in foil and heat in the toaster oven for 10-15 minutes for a freshly baked taste.
