Frequently Asked Questions
The main difference between a crustless quiche and a frittata is that a frittata is typically cooked in a skillet, whereas quiches are baked in the oven in a pan or baking dish at a lower temperature.
Nope! Just throw the finely-chopped broccoli raw into the quiche and it’ll cook alongside the rest of the ingredients.
You can make a quiche from just egg whites rather than whole eggs, but you will have to alter the recipe. You will need two egg whites for every egg – so use 24 egg whites to replace the 12 eggs in this crustless broccoli quiche. Also, start checking the quiche for doneness earlier. Egg whites by themselves will not take as long to cook through. This Egg White Frittata is a similar recipe to this one using egg whites only.
Storing and reheating
Leftover crustless quiche can be stored in the refrigerator for up to 5 days. A single leftover piece can be reheated in the microwave for a minute or two – sprinkle some water over top first to help the quiche retain its moisture.
Because this dish lasts in the refrigerator, you can cook it ahead of time and just reheat the entire quiche when you plan to serve it. It will cook more evenly if you let it come to room temperature before putting it in the oven. Reheat the quiche in the oven at 350° Fahrenheit for about 20 minutes.
Freezing this recipe
For even longer storage, you can freeze this quiche. Wrap it tightly in plastic wrap and store it in the freezer for 3-4 months.
When you’re ready to enjoy this dish, let the quiche thaw in the refrigerator overnight before reheating. If necessary, you can cook it from frozen, but it will take about 30-40 minutes at 350° Fahrenheit.
