Crustless quiche is a great light breakfast and brunch dish because it’s incredibly versatile and so easy to make. This is our family’s favorite quiche made with bacon, cheddar, mushrooms, and spinach but without crust. The best part is that you can prepare it ahead of time and bake the next morning.
Have you ever looked at a house full of relatives that are visiting for the holidays and wondered how you would feed everyone? Sure, you have dinner planned, but what about breakfast or brunch? I’ve got you covered!
Egg dishes like quiche, breakfast bakes, and breakfast casseroles are wonderful to serve on weekends, especially for a larger group of people. The dish is incredibly easy to whip up, and everyone will love it. You can even prep it the night before and bake it in the morning!
Not only is it an easy and delicious breakfast, but it’s light and nutritious, too!
No crust means low carb, which keeps the meal lower in calories. The eggs provide plenty of protein, and there are plenty of healthy veggies like spinach and mushrooms!

Ingredients and Substitutions
- Canola Oil – you can substitute it with light tasting olive oil too.
- Bacon – Pork bacon is ideal, but you can also use turkey bacon for a healthier option.
- Shallots – shallots have a great slightly sweet flavor with a touch of garlic.
- Cremini Mushrooms – These are also known as baby bella mushrooms. Their ability to withstand high temperatures and savory flavor make them the perfect choice for this recipe.
- Baby Spinach – Baby spinach has a milder flavor than one of the mature spinach but if you wish, you can use mature spinach instead.
- Eggs – use large eggs.
- Whole Milk– use whole milk and try not to use lower fat milk. For a richer taste, mixing in half-and-half or heavy whipping cream is a great choice!
- Sharp White Cheddar Cheese – for best taste, you want sharp cheese with a lot of flavor. So if white cheddar is not available, use your favorite flavorful cheese that melts well.
- Cracked Black Pepper
What is crustless quiche?
Simply put, it is a breakfast dish that consists of baked eggs. It’s lighter than traditional quiche because there is no crust and usually contains whole milk rather than cream.
You can use a round ceramic baking dish or any other shape you wish. Most often, people choose the round baking dish so it still retains the look of a traditional quiche.
As far as the filling, there are so many options for proteins and vegetables, you can modify it to your family’s favorite flavors.
How to Make It
Prepare the ingredients. Dice the raw bacon, chop the vegetables and grate the cheese.
TIP: dice bacon while it’s still cold because cold bacon is much easier to cut.
Sauté bacon and shallots. Cook with oil over a medium high heat until the bacon fat is rendered half way. Then, stir in the diced shallot and cook together until fat is mostly rendered.
Add vegetables. Add mushrooms first, cooking until they’re mostly done before tossing in the chopped spinach. Cook together until the spinach is wilted.
Strain the mixture. Too much liquid will thin the quiche, so make sure you drain off excess juices that accumulated in the pan before adding the mixture into the eggs. Let it cool for a few minutes.
Whisk the eggs. Whisk together the eggs, salt, and pepper until smooth.
Mix the ingredients. Mix in the filling with the eggs. Once mixed, spread the mixture into the prepared baking dish.
Add cheese. Spread grated cheese over the top of the mixture and gently press it down, so that it’s mostly covered with egg. (If you wish, you can mix cheese with the egg mixture in the mixing bowl.)
Bake the quiche. Bake the dish for about 40-45 minutes. Before serving, make sure to let it rest for at about 15 minutes so that it cools down.
Slice and serve with a dollop of sour cream on top!
What’s The Difference Between Crustless Quiche and Frittata?
While these egg based breakfasts are similar, they’re also quite different. A frittata is made with almost no dairy, resulting in a firm texture that’s comparable to an omelet. A crustless quiche contains whole milk or cream, making it softer, creamier, and silkier.
Can I Use Different Vegetables and Proteins?
Absolutely! While the ingredients listed in this recipe are my personal favorites, you can really get creative with what you want to add in.
For proteins, you can use leftover diced ham, bacon, sausage, and even rotisserie chicken.
Try vegetables like chopped bell peppers, onions, tomatoes, broccoli, carrots, and so many more. Just remember, it’s best to sauté vegetables first.
You can always use different cheeses and even add some extra to make it extra cheesy.
What To Serve With Crustless Quiche?
Quiche is great to serve as breakfast or brunch so you can serve it with a side of sausage and bacon meats or with a side salad. You can also make the cheesy and comforting hashbrown casserole as a side. Try a side of roasted potatoes as well.
