Can you refreeze a previously frozen quiche?

Yes, you can refreeze a previously frozen quiche, but it's best to do so only if it has been thawed in the refrigerator and not left out at room temperature. Refreezing may affect the texture and quality, so it's advisable to consume it after it has been thawed for the best taste. Always ensure that the quiche is properly wrapped or sealed to prevent freezer burn.
