A Crustless Quiche recipe is perfect when you want to avoid the calories and time required to make a pie crust. It is simple, delicious and a perfect way to clean out your fridge.

A classic quiche is a savoury, rich custard made with eggs, vegetables like cauliflower and broccoli, herbs, and cheese, all set in a pie crust. I love the no-crust Quiche because I don't have to make the crust, which is challenging to roll out in our hot weather.
During the pandemic, for Apeksha's birthday we had a Tea Party and made quiches, cucumber sandwiches, Orange Marmalade scones, Cheddar and Sage Scones, Cobbler and Victoria Sandwich Cake.

What is Quiche?
Quiche is an open pie with a crust, filled with cream and a variety of cheese. A classically made quiche uses a pie base heavy on butter, and the filling uses eggs, heavy cream, cheese, meat and/or vegetables.
Because of" Quiche Lorraine", Quiche is assumed to be French cuisine; however, it is said to have originated in Germany. The German "Kuchen", which means the cake, is the root of Quiche.
This crustless Quiche, without cream and meat, tastes much better than the store-bought one.
Serve Quiche for brunch, lunch, an entrée, dinner, or supper. Celebrations like Easter, baby showers, bridal showers, potlucks, and tea parties. It can be served hot or cold, and it is perfect for a make-ahead meal or a potluck party. Leftovers? We are happy to finish it all for breakfast.
A quick recipe that's delicious yet simple, versatile, and consistently good. A crowd-pleasing recipe that is adaptable to all the surprises my refrigerator throws at me.

Substitutes for Crustless Quiche
- Vegetables: You can also use broccoli, beans, carrots, corn, spinach, and potatoes, to name a few. In general, I add the veggies that the girls try to avoid.
- Whole Wheat Flour: I use whole wheat flour in place of maida (all-purpose flour). You can use what you are comfortable with.
- Eggs: If you are not an egg-eater, then substitute the egg with agar-agar. You can check the recipe for the Eggless Quiche I made previously. My father-in-law loved it.
Variations for Crustless Quiche

- Soak 15 grams of agar agar in a cup of water.
- Make a white sauce and add the agar agar, stirring constantly.
- Add to the veggies, white sauce and cheese and bake.
- Veggies: Use broccoli, corn, spinach, carrots, and potatoes. If in a hurry, use frozen veggies.
- This recipe is a vegetarian crustless quiche. You can also use the meats of your choice.

Protips for Crustless Quiche
- Since the crustless quiche, coat the baking tray with butter.
- You can cook the veggies a day ahead and refrigerate them.
- You can set up the veggies and white sauce in the greased baking tray. Use cling wrap to refrigerate the tray, let it come to room temperature, and then bake it.
- The centre of the baked quiche may wriggle a little. When you insert a toothpick, it should be dry and free of wet batter.
- Avoid overcooking the quiche so it does not become rubbery. The quiche continues to cook out of the oven.
- Store the cooked quiche in an airtight container for 3 days.
- Reheat the quiche in the oven at 180℃ or 356℉. You can microwave it too.
- Freeze the cooked crustless quiche for about 3 months. Thaw the quiche in the fridge overnight before reheating.
