Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Start with the pastry. Place the flour, salt, and thyme in a large mixing bowl and whisk to combine. Add the cold cubed butter and use your fingertips to rub it into the flour until the mixture resembles breadcrumbs. Keeping the butter cold and working quickly prevents the gluten in the flour from developing too much, ensuring a flaky rather than tough pastry.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Add the ice-cold water one tablespoon at a time, mixing with a knife until the dough just comes together. You may not need all the water – stop adding once the dough forms clumps that hold together when pressed. Form the dough into a disc, wrap in cling film and refrigerate for at least 30 minutes. This resting period allows the gluten to relax and the butter to firm up again, preventing shrinkage during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>While the pastry rests, prepare the caramelized onions. Heat the olive oil in a large frying pan over medium-low heat. Add the sliced red onions with a pinch of salt and cook, stirring occasionally, for about 25-30 minutes until they become very soft and deeply golden. The slow cooking develops the natural sugars in the onions, creating a sweet depth of flavor.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the balsamic vinegar and brown sugar to the onions, stir well, and cook for another 5 minutes until the mixture is sticky and jammy. Remove from heat and let cool slightly. The vinegar adds acidity that balances the sweetness and helps deepen the caramelization.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Preheat your oven to 190°C (170°C fan/375°F). Roll out the chilled pastry on a lightly floured surface until it's about 3-4mm thick and large enough to line your tart tin with some overhang. The thinness ensures a crisp, properly cooked base.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Carefully transfer the pastry to your tart tin, pressing it gently into the corners without stretching it. Trim any excess pastry, leaving a small overhang to allow for shrinkage. Prick the base all over with a fork (this prevents air bubbles), then line with baking parchment and fill with baking beans or rice.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Blind bake the pastry case for 15 minutes, then remove the parchment and baking beans and return to the oven for another 5-7 minutes until the base is just starting to color but not fully baked. This partial baking ensures the crust won't become soggy once filled.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>While the pastry case is baking, prepare the filling. In a large bowl, whisk together the eggs, double cream, and milk until well combined. Season generously with salt and freshly ground black pepper. The proteins in the eggs will set during baking, creating a creamy, custard-like texture.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Spread the caramelized onions evenly over the base of the partially baked pastry case. Crumble about two-thirds of the goat cheese over the onions, then pour in the egg mixture. The remaining cheese will be added later to create attractive pockets on top.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Crumble the remaining goat cheese over the top and sprinkle with the fresh thyme leaves. Bake in the preheated oven for 25-30 minutes until the filling is set but still has a slight wobble in the center. The residual heat will continue cooking the quiche after it's removed from the oven.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Allow the quiche to cool in the tin for at least 20 minutes before removing. This cooling period allows the filling to set completely and makes it easier to slice cleanly. Garnish with extra fresh thyme leaves before serving.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Serve warm or at room temperature with a crisp green salad. The quiche can be stored in an airtight container in the refrigerator for up to 3 days and gently reheated in a 150°C oven for about 15 minutes until warmed through.</li></ol>

What ingredients are used in Red Onion and Goat Cheese Quiche?

This quiche requires plain flour, butter, salt, thyme, and water for the pastry. The filling includes red onions, olive oil, balsamic vinegar, brown sugar, eggs, double cream, milk, soft goat cheese, thyme, salt and pepper. These create a perfect balance of sweet and tangy flavours.

How to cook Red Onion and Goat Cheese Quiche at home?

Learn how to cook Red Onion and Goat Cheese Quiche by first making a buttery pastry, then blind baking it until partially cooked. Meanwhile, caramelise red onions slowly with balsamic vinegar and brown sugar. Create a custard with eggs, cream and milk, then assemble by layering onions and goat cheese in the pastry case, pouring over the custard and baking until just set with a slight wobble.

What's the secret to perfectly caramelised onions for quiche?

The secret is patience and low heat. Cook sliced red onions over medium-low heat for 25-30 minutes, stirring occasionally. Adding a pinch of salt helps draw out moisture. Finish with balsamic vinegar and brown sugar for depth. Never rush this process—slow cooking develops the natural sugars for that distinctive sweet-savoury flavour.

Can I make this savoury tart ahead of time for entertaining?

Yes! This quiche is perfect for make-ahead entertaining. Bake it the day before, cool completely, and refrigerate. Reheat at 150°C for 15-20 minutes until warmed through. You can also freeze individual slices for up to 3 months—simply thaw overnight in the fridge before reheating for perfect results.

What's the best way to prevent a soggy bottom on my quiche?

Always blind bake your pastry case first using baking parchment and beans. Prick the base with a fork before blind baking to prevent air bubbles. Make sure the base is starting to colour before adding your filling. Using cold butter in the pastry and resting it properly also helps create a crisper, flakier base.
