Mushroom Leek And Gruyère Tart Recipes

MUSHROOM, LEEK, AND GRUYèRE TART

Steps:

• Preheat the oven to 425°F (218°C).
• On a sheet of parchment paper cut to fit a rimmed baking sheet, roll the puff pastry sheet into a 10-by-10-inch square, gently smoothing out any creases in the pastry. Using a sharp knife, lightly score the pastry, leaving a 1-inch border all along the outer edge and being careful not to cut all the way through the pastry. Carefully slide the parchment with the scored pastry onto a rimmed baking sheet and refrigerate while you prepare the topping.
• In a large skillet over medium heat, melt the butter. When it bubbles, toss in the garlic and thyme and cook for 1 minute. Add the leeks and cook until they begin to soften. Add the mushrooms and cook until they're soft but not yet releasing any liquid. Dump the mushroom filling in a strainer situated over a bowl and let drain for a few minutes.
• Spoon the mushroom filling onto the pastry, being careful to stay inside the scored lines. Either reserve the strained mushroom liquid for making vegetable stock or discard it. Grind fresh black pepper, if using, over the topping.
• Bake the tart for 15 minutes, checking the puff pastry after 10 minutes. If the pasty is already golden brown, cover the exposed pastry edges with foil strips to prevent it from turning too brown. After the first 15 minutes, remove the tart from the oven and sprinkle it with the cheese. Bake for 5 to 7 minutes more, or until the cheese has melted and the pastry is golden brown. Again, it may be necessary to cover the outer edges with foil.
• Let cool for 5 minutes and then slice into squares or rectangles. This tart is best eaten as soon as it is cool enough to handle. (Any leftover mushroom leek tart can be wrapped and refrigerated, but the pastry will suffer. To reheat, pop under the broiler for a few minutes. Whatever you do, don't reheat the tart in the microwave.)

LEEK, MUSHROOM & GRUYèRE QUICHE

Steps:

• To make the pastry, tip the flour and butter into a bowl, then rub together with your fingertips until completely mixed and crumbly. Add 8 tbsp cold water, then bring everything together with your hands until just combined. Roll into a ball and use straight away or chill for up to 2 days. The pastry can also be frozen for up to a month.
• Roll out the pastry on a lightly floured surface to a round about 5cm larger than a 25cm tin. Use your rolling pin to lift it up, then drape over the tart case so there is an overhang of pastry on the sides. Using a small ball of pastry scraps, push the pastry into the corners of the tin (see picture, above left). Chill in the fridge or freezer for 20 mins. Heat oven to 200C/fan 180C/gas 6.
• While the pastry is chilling, heat the butter in a pan and cook the leeks for 10 mins, stirring occasionally, until they soften. Then turn up the heat and add the mushrooms. Cook for 5 mins more, then turn off the heat.
• Lightly prick the base of the tart with a fork, line the tart case with a large circle of greaseproof paper or foil, then fill with baking beans. Blind-bake the tart for 20 mins, remove the paper and beans, then continue to cook for 5-10 mins until biscuit brown
• While the tart case cooks, beat the eggs in a bowl, then gradually add the cream. Stir in the leeks, mushrooms and half the cheese. Season, then tip the filling into the tart case. Sprinkle with the rest of the cheese, then bake for 20-25 mins until set and golden brown. Leave to cool in the case, trim the edges of the pastry, then remove and serve in slices.

LEEK, RICOTTA & GRUYèRE TART

Steps:

• Heat oven to 200C/180C fan/gas 6. Roll out the pastry and use to line a 23cm loose-bottomed tart tin. Prick the base with a fork and line with baking parchment and baking beans. Sit the tin on a baking sheet and bake for 10 mins, then remove beans and parchment and return to the oven for a further 5 mins until pale golden. Reduce oven to 180C/160C fan/gas 4.
• Meanwhile, melt the butter in a large pan and gently cook the leeks for 10 mins until softened. Beat together the ricotta, cream, eggs, tarragon, a little salt and plenty of black pepper. Stir in the leeks and all but a handful of the cheese.
• Pour the mixture into the tart case and scatter over the remaining cheese. Bake for 25-30 mins until golden and set. Leave to settle for 5 mins, then carefully remove from the tin and allow to cool a little on a wire rack. Serve warm.
