Reheat Quiche in an Air Fryer

Doneness

The pastry bottom is golden-amber and flaky when lifted with a server — not pale or soggy. The custard interior reads 165 °F (74 °C) on an instant-read thermometer probed at the deepest point. The top surface has a thin glossy sheen with no curdled weeping or cracked dry zones. For the crustless quiche variant, skip the foil entirely and bake uncovered the full 6 minutes.

Technique

Place wedges straight from the fridge onto a parchment-paper basket liner — no room-temperature rest. Loosely rest a 4-inch square of aluminium foil on top of each wedge (do not seal the edges down). Set the fryer to 320 °F / 160 °C for 6 minutes total without preheating. At the 4-minute mark, open the basket and remove the foil with silicone-tipped tongs. Finish the final 2 minutes uncovered so the top crisps without scorching. Do not flip. Transfer wedges to a warmed plate and rest 60 seconds before serving.

Watch out for

• !Use 320 °F, not 350 °F. The higher temperature scorches the pre-baked pastry crust and curdles the egg-cream custard within 90 seconds on the already-dried leftover surface, while the dense centre stays cold. The lower temperature lets convection gently re-warm the custard from outside in.
• !Tent with foil for the first 4 minutes, then remove for the final 2. Without the foil, the pastry crust and custard top scorch before the centre reaches 165 °F. Rest the foil loosely — do not seal the edges, or trapped steam will collapse the pastry bottom. Use tongs to remove the foil at the 4-minute mark.
• !Do not microwave leftover quiche. Microwave heat produces soggy pastry, rubbery overcooked egg, and curdled cream pockets — the most common quiche-leftover failure.
• !Go straight from fridge to basket; no room-temperature rest. Quiche is an egg-and-dairy product; leaving it above 40 °F / 4 °C for more than 2 hours raises food-safety risk. The 6-minute profile is calibrated for fridge-cold wedges — room-temperature wedges on the same timing will overcook and curdle.
• !Reheat in individual wedge batches; a whole uncut quiche is impractical here. The 6-minute cook is sized for 1–2 wedges from a 7-inch pan. Mini quiches (muffin-tin format) cook faster — use 320 °F / 4 minutes total: foil tent for the first 2 minutes, then uncovered for the final 2.
