Leek and Lancashire Cheese Quiche

Leek and Lancashire Cheese Quiche — Thermomix TM7

Leek and Lancashire Cheese Quiche is a savoury vegetarian main course combining sweet, buttery leeks with crumbly Lancashire cheese in a creamy egg custard, all nestled in homemade shortcrust pastry. The Thermomix TM7 handles everything: weighing flour and butter to the gram, kneading pastry, slicing leeks evenly and blending the custard silky smooth for a bakery-quality result.

About this recipe

Leek and Lancashire Cheese Quiche Thermomix TM7 is a classic British bake that turns humble ingredients into an elegant vegetarian main course. Searching for quiche recipes for your all-in-one kitchen machine often leads to complicated pastry methods, but here the TM7 takes care of everything: the built-in scale weighs plain flour, butter and water directly into the mixing bowl, the kneading function brings the shortcrust together in moments, and rapid chopping turns whole leeks into even rings without a knife or chopping board. Lancashire cheese, with its crumbly texture and fresh tang, melts into a single cream and egg custard that the machine blends until perfectly silky. This is an ideal quick weeknight dinner when served with a green salad, yet smart enough for a weekend brunch or buffet table. The contrast between the crisp, buttery pastry and the soft, savoury filling is what makes this quiche a permanent favourite in British kitchens, and the Thermomix TM7 makes achieving it genuinely straightforward.

Preparation tips

  • Chill the shortcrust pastry in the mixing bowl lid or cling film before rolling, as cold butter within the dough is what gives the quiche its crisp, flaky base rather than a soggy bottom under the leek filling.
  • Slice the leeks and rinse them thoroughly in a colander to remove hidden grit between the layers; sandy leeks are the most common reason a quiche filling turns gritty instead of meltingly soft.
  • Grate the Lancashire cheese coarsely rather than finely so it stays in distinct melty pockets throughout the custard; serve the baked quiche lukewarm, as Lancashire tastes sharper and more flavourful when not piping hot.

Recipe variations

  • Lactose-light version: replace the single cream with oat cream and use a mature lactose-free Cheddar instead of Lancashire; keep the buttery shortcrust made with plant-based block margarine so the leek filling stays just as silky.
  • Festive seasonal version: add crispy fried bacon lardons or, for a vegetarian Christmas twist, stir in chestnuts and a pinch of nutmeg with the leeks, then top with extra Lancashire before baking for a golden holiday centrepiece.
