ONION MUSHROOM QUICHE RECIPES

Steps:

• Preheat the oven to 400 degrees F. Spray a 9-inch pie dish with cooking spray.
• To prepare the crust, put the oats, flour and salt in the bowl of a food processor and pulse 3 times to combine. Add the butter and pulse about 12 times, until you get a pebbly course texture. Add the buttermilk and pulse 3 to 5 times more to combine. Form the mixture into a ball and place it between 2 large pieces of waxed paper. Roll out into a circle about 10 inches in diameter.
• Remove the top sheet of waxed paper. Transfer the crust, still on the other piece of waxed paper to the pie dish, then remove the waxed paper from the top. Press the crust gently into the dish. Bake for 9 minutes, then let cool.
• To prepare the filling, heat 2 teaspoons of oil in a large nonstick pan over a medium-low heat. Add the onion and cook, stirring occasionally, until golden brown and caramelized, about 20 minutes. Transfer the onions to a bowl. Add the remaining 2 teaspoons of oil to the pan and heat over a medium-high heat. Add the mushrooms and cook, stirring occasionally, until they have released their water and begin to brown, about 6 minutes. Add the onions back to the pan, stir in the salt, pepper, mustard and thyme.
• In a medium bowl whisk together the eggs, egg whites and evaporated milk.
• Sprinkle the cheese into the pie crust. Top with the mushroom-onion mixture and pour the egg mixture on top. Reduce oven temperature to 350 degrees F. Bake for 35 minutes or until knife inserted in the middle comes out clean. Let stand for 5 minutes before cutting into 6 wedges and serving.

Steps:

• Heat the oven to 180°C fan/gas 6. For the pastry, put the flour, salt and butter in a food processor, then pulse to a breadcrumb consistency. In a small bowl, beat the egg with 2 tbsp of the water. Add to the flour and whizz briefly to bring the pastry together, adding the remaining tbsp of water if needed. (If you don’t have a food processor, rub the butter into the flour/salt with your fingers, then add the yolk/water and mix with a dinner knife.) Turn out onto a floured work surface, then bring together in a ball (see Make Ahead). Roll out the pastry to a 30cm disk and use to line the tart tin. Leave a little pastry overhang (don’t trim), then chill for 30 minutes.
• Prick the chilled pastry base all over with a fork, then line with a piece of baking paper (scrunch it up, then flatten it out again so it fits the shape of the case more easily). Fill with ceramic baking beans or uncooked rice, then blind bake for 20 minutes. Remove the paper and beans/rice and bake for 8-10 minutes more until golden and the pastry feels sandy. Remove from the oven, set on a baking tray and trim the pastry overhang with a serrated knife. Turn down the oven to 150ºC fan/gas 3½.
• For the filling, whisk the cream, milk and eggs together in a large bowl. Add the grated cheese, caramelised onions and mustard with a pinch of salt, then stir to combine. Pour the filling into the hot tart shell (see Know-how), then return, on the baking tray, to the oven for 45 minutes or until set with a slight wobble in the centre. Cool, then slice and serve.
