Quick Answer
Reheat your ham, cheddar and caramelised onion quiche in a 325°F (160°C) oven for 10–15 minutes to keep the pastry crisp and the custard from drying out.
Why the oven beats the microwave
The microwave is fast, but it turns the short, crumbly pastry soggy and can make the egg custard rubbery. The oven's dry heat restores the pastry's crispness and warms the filling gently without overcooking the eggs.
If you're in a hurry, the microwave can work in a pinch—just know you'll trade some texture. For the best results, especially with a pastry as delicate as this quiche, the oven is worth the extra minutes.
Step-by-step reheating guide
- Preheat the oven: Preheat your oven to 325°F (160°C). A moderate temperature prevents the pastry from burning while the filling warms through. Check your oven's accuracy with an oven thermometer if you're unsure.
- Prepare the quiche: If the quiche is refrigerated, let it sit at room temperature for 10 minutes. Place it on a baking sheet lined with parchment paper to catch any drips. Don't skip the room-temperature rest—it helps the quiche heat evenly.
- Reheat in the oven: Bake for 10–15 minutes, or until the internal temperature reaches 165°F (74°C) and the pastry is crisp. If you want extra browning, switch to broil for the last 1–2 minutes, but watch it closely. Use a food thermometer to avoid overbaking, which can dry out the custard.
- Rest and serve: Let the quiche rest for 2–3 minutes before slicing. This allows the custard to set slightly, so it holds its shape when you cut it. Resting also prevents the filling from running out when you slice.
- Microwave shortcut (optional): For a quick reheat, microwave a single slice on a microwave-safe plate for 30–45 seconds at 50% power. The pastry won't be as crisp, but it's fine when time is short. If you have a toaster oven, use it instead—it gives a better texture than a microwave.
