Best 5 Caramelized Leek Quiche Recipes

BACON, CHEESE, AND CARAMELIZED ONION QUICHE

Steps:

• Preheat the oven to 350 degrees F (175 degrees C).
• Fry bacon in a large skillet over medium-high heat, turning occasionally, until crispy, about 10 minutes. Drain bacon slices on paper towels. Let cool 10 minutes. Crumble and set aside.
• Roll out pastry crust into a circle using a lightly floured rolling pin. Line a 9-inch pie pan with crust. Prick holes into the base of the dough using a fork.
• Bake crust in the preheated oven on the middle rack for 15 minutes.
• Remove pastry crust from the oven. Brush crust with beaten egg. Return crust to the oven and bake 5 minutes more.
• Heat butter in a pan over medium heat and stir in onion. Cook and stir until onion has softened and turned translucent, about 5 minutes. Reduce heat to low and continue cooking and stirring until onion is very tender and dark brown, about 40 minutes more.
• Whisk 2 eggs together in a bowl using a fork. Add sour cream and cream cheese and beat using an electric mixer until well combined. Beat in salt and pepper.
• Spread caramelized onions with remaining butter onto pastry crust. Sprinkle with 1/2 the Cheddar cheese. Place crumbled bacon evenly over the top. Pour egg mixture over bacon. Top with remaining Cheddar cheese.
• Bake quiche in the preheated oven until golden and fluffy, about 30 minutes. Let cool 10 minutes before serving.

CARAMELIZED LEEK QUICHE

Steps:

• On a lightly floured surface, roll out dough to a 12-inch circle. Fit dough into a 10-inch round fluted tart pan with a removable bottom, pressing into edges. Trim dough to a 1/2-inch overhang all around. Fold edge of dough over to create an edge that extends 1/4-inch above the pan. Lightly prick bottom of dough all over with a fork. Chill until firm about 30 minutes.
• Preheat oven to 375 degrees. Line bottom of dough with parchment paper, leaving at least a 1-inch overhang. Fill with pie weights or dried beans. Bake until the edges are just beginning to turn golden, about 30 minutes. Remove parchment paper and weights; continue baking until lightly golden all over, 10 to 15 minutes more. Cool tart shell completely on a wire rack.
• Heat olive oil in a medium skillet over medium heat. Add leeks and thyme and cook, stirring occasionally, until leeks soften and begin to brown, 10 to 15 minutes. Season with salt and pepper.
• Sprinkle half of the cheese over the bottom of the tart shell, top with cooked leek mixture and sprinkle with remaining cheese. In a medium bowl, whisk together eggs, yolk, milk, cream, and a pinch of salt and pepper. Pour mixture over leeks and cheese. Bake until puffed and golden brown, 30 to 35 minutes. Transfer to a wire rack to cool 10 minutes before serving, or serve at room temperature.

CARAMELISED ONION QUICHE WITH CHEDDAR & BACON

Steps:

• Melt the butter in a large non-stick frying pan, add the onions and cook for 20 mins, stirring now and then, until they are soft and golden brown. Season, stir in the thyme leaves, then transfer to a plate to cool.
• Heat oven to 200C/180C fan/gas 6 with a large baking sheet inside. Roll out the pastry on a lightly floured surface until large enough to line a 25cm loose-bottomed tart tin, with a little overhang of pastry all the way round the top. This will stop the pastry shrinking in the oven later. If there is more overhang than you need, trim off the excess with scissors. Gently press the pastry into the sides of the tin and prick the base with a fork. Chill for 15 mins.
• Line the pastry case with a sheet of baking parchment and fill with ceramic baking beans. Bake for 15 mins on the hot baking sheet (this helps to prevent a soggy bottom). Carefully remove the parchment and beans, then return to the oven for 10 mins more until the pastry looks cooked like shortbread, but is not too brown.
• Meanwhile, put the bacon in the pan you cooked the onions in (there's no need to wash it first or add any oil) and fry for 10 mins until golden. Lift from the pan onto kitchen paper to remove any excess fat. Beat the cream, milk and eggs with seasoning and nutmeg, then stir in the bacon and half the cheese.
• Remove the pastry case from the oven and reduce heat to 190C/170C fan/gas 5. Spoon the caramelised onions evenly over the base of the pastry case. Pour in the bacon mixture, then scatter with the remaining cheese, the thyme sprigs and a little nutmeg. Bake for 25-30 mins until golden and the filling is just set with a slight wobble in the centre.
• Trim the excess pastry and leave to settle for 10 mins, then remove from the tin and slice.

CARAMELIZED ONION AND BACON QUICHE

Steps:

• Preheat oven to 425 degrees. Unroll pie crusts and stack on a lightly greased surface. Roll into at least a 12-inch circle, depending upon the size of your pan. Mold pie crust into a deep dish pie pan or 10-inch deep dish tart pan with removable bottom. Trim off excess pie crust along edges. Place a sheet of aluminum foil or parchment paper on pie crust and place pie weights or dried beans on top. Place on a foil-lined baking sheet and bake for 10 minutes. Remove weights and foil and bake an additional 8 minutes. Cool completely, about 15 minutes.
• Reduce oven temperature to 350 degrees.
• While piecrust is baking, cook onions in olive oil, butter, and bacon grease in a large skillet over medium-low heat. Stir often and cook for 15 to 20 minutes, until caramel colored. Remove from heat and add bacon crumbles to pan with onions.
• Place half of onion-bacon mixture in piecrust and top with half of cheese. Repeat with remaining onions and cheese.
• In a medium bowl, whisk together half-and-half, eggs, salt, pepper, and nutmeg. Pour over cheese.
• Bake for 40 to 45 minutes at 350 degrees, or until set. Cool 15 minutes before serving.
