This Crustless Quiche Recipe is a healthier version of classic quiche and just as versatile, filling, and delicious. Low-carb, gluten-free, and filled with broccoli and cheese, it’s the perfect easy meatless dinner or lunch.
Crustless Quiche Recipe
I could eat a slice of this crustless quiche every day, week after week – and never miss the crust. It’s perfectly delicious, even without the buttery crust, and so much better for you! Skipping the crust not only cuts down on carbs and calories but also saves you a ton of prep time and cook time.
For this recipe, I chose to add some classic quiche fillers: shallots, broccoli, and Gruyere cheese. It’s similar to classic quiche Lorraine (my favorite), but without the crust or bacon. Of course, feel free to substitute with other quiche additions. Some of my favorites include:
The best part? All quiche, including this crustless quiche, reheat beautifully. So hang on to any leftovers or make two so that you’ll have an extra to enjoy later in the week.
Milk vs. Cream
Crustless quiche can be made using heavy cream, half-and-half, whole milk, 2% milk, or some combination of those listed. Heavy cream is most often used in quiche recipes and will produce the most custard-like filling.
How to Make Crustless Quiche
Set the oven to 325°F and grease a 9-inch deep-dish pie plate with butter. Non-stick cooking spray will also work, but butter is best.
In a large 12-inch skillet melt the butter over medium heat. Cook the shallots until softened. Next, add the broccoli, half of the salt, and 1/4-cup water. Cover and cook the broccoli until al dente then remove the lid and continue to cook until the water has evaporated.
Whisk together the eggs, half-and-half, milk, and nutmeg with the remaining teaspoon of salt. Spread the broccoli and shallots over the bottom of the pie dish creating a vegetable crust, then sprinkle with cheese. Pour the egg mixture over the top of the cheese and broccoli.
Cook for about 1 hour, or until the internal temperature registers 170 degrees F.
If you notice that your custard has not yet set and the top is starting to brown, carefully tent with aluminum foil until it has finished cooking. Allow your quiche to cool for 10 minutes before slicing.
Difference Between Quiche and Frittata?
Both quiche and frittata are made with eggs and some combination of cheese, meat, and/or vegetables. Their differences include,
- Traditionally, quiche is made with a buttery pie crust while a frittata is not (crustless quiche being the exception).
- Quiche is made with some combination of milk or cream with eggs, whereas frittatas are usually made with only eggs.
- Finally, frittatas are first cooked on the stovetop before being transferred to the oven to finish cooking; quiche and crustless quiche are cooked entirely in the oven.
Storage and Reheating
Crustless quiche is delicious leftover. It’s even freezer friendly!
- Storing: Leftovers can be stored in an airtight container in the refrigertor for up to 4 days.
- Freezing: Cool completely before wrapping first in plastic wrap and then in a tight layer of aluminum foil. For best results, freeze quiche by the slice. Can be frozen for up to 3 months. Thaw in the refrigerator overnight before reheating.
- Reheating: Reheat individual slices in the microwave for 30-60 seconds, or until heated through. To reheat a whole quiche, cover with aluminum foil and bake in a 300° oven for about 30 minutes, or until heated through.
