Crustless Quiche: FAQs
Typically, it is a pastry case filled with eggs, cheese, meat, seafood, and/or vegetables. In this case, we’ve omitted the pastry (aka the crust) for a lower carb option.
You will want to eat refrigerated or leftover quiche within 3-4 days.
Yes! Quiche can be frozen before baking or after baking. Note that baking it first may make the quiche a little easier to deal with in the freezer.
To freeze quiche before baking: Place the quiche on a baking tray and freeze until firm. Wrap with freezer paper or heavy-duty (or double thickness) aluminum foil or slide quiche into a freezer bag – seal, label and freeze for up to three months. When ready to serve, remove from the freezer. Do not thaw. Unwrap and bake, as usual, adding an extra 10 to 20 minutes to the baking time.
To freeze quiche after baking: Proceed as above. Do not thaw before reheating. Remove wrap and bake in a preheated 350°F oven for about 25 minutes, or until heated through.
You can reheat the whole quiche in a 350°F oven for about 25-30 minutes or until heated through. Alternatively, for a slice of quiche, heat it in the microwave at 50% power for about 3 minutes or until heated through.
Personally, I love a simple, fresh lettuce salad with fresh veggies like tomatoes, cucumbers, radishes, and thin sliced red onion. Other good choices are steamed broccoli or asparagus, fruit salad, a small bowl of soup, crusty bread, cucumber salad – or whatever you like!
