Reheating quiche requires a gentle approach to ensure it retains its delightful texture and flavour. First, preheat your oven to 160°C (320°F), as this method helps to evenly warm the quiche without drying it out. If your quiche is whole, it’s best to place it directly on the oven rack or a baking tray for about 20–25 minutes, checking occasionally to avoid overheating.

For individual slices, you can wrap them in foil to maintain moisture, ensuring they stay tender and delicious; this should take around 10–15 minutes. Alternatively, if you're short on time, a microwave can be used, but it’s advisable to heat in short bursts of 30 seconds, checking frequently to preserve the creamy filling.

Once heated, let it sit for a minute before serving, allowing the flavours to settle. Enjoy your quiche once again as though it’s freshly baked!
