This is SUCH a delicious quiche - I do recommend it. Even my picky eater liked it - I think it was the saltiness from the cheese. I would have loved to have got a shot of it in its entirety but they descended on it like vultures. It's a good thing I deftly whisked a slice away for this photo. I had been toying with the idea of adding mushrooms or crispy pancetta but in the end I decided to be sparing, I'm so glad I did. Hope you enjoy this.
For the pastry.
1 cup white wholewheat flour
2 cups all purpose flour
1 egg yolk
2 sticks of unsalted butter, diced and chilled
3/4 - 1 cup of iced water
salt and pepper
For the filling.
1 cup cream
1 cup milk
1 bunch Swiss chard, trimmed and chopped
3 onions, sliced
1 tablespoon butter
6-8 oz Pecorino cheese
Pinch of nutmeg
To make the pastry combine the flours, salt and pepper and fresh thyme in a food processor and pulse approx 10 times.
Add the butter down the funnel and combine for a few pulses. With the machine on, add the egg and then the water slowly until the mixture comes together, you may only need 3/4 cup.
Turn the pastry out onto a sheet of plastic wrap. Shape into a disc, wrap and put into the fridge for at least 30 minutes.
Meanwhile pour a good couple of tablespoons of olive oil and a tablespoon of butter into a pan and heat. Add the onions and allow to caramelize on a low heat. This could take up to 20 - 25 minutes.
Wash and chop the Swiss chard and set aside.
When the onions have caramelized add the Swiss chard and combine.
Mix together the eggs, milk, cream, 3/4 of the cheese and nutmeg. Set aside.
After thirty minutes take the pastry out of the fridge. Flour a surface on your counter top and roll out the dough. Lay it into a pie dish, trim the edges.
Transfer the onion mixture into the pie dish and pour over the egg mixture, combine gently.
Sprinkle over the remainder of the cheese.
Transfer to a baking sheet and place on the middle rack of the oven.
Bake for approx 1 hour until risen and golden the filling is set.
Allow to cool thoroughly (although this didn't happen in my house!)
