I’m a quiche lady.  I love the combination of eggs and fresh veggies cooked in a pastry crust – especially when I have grown those vegetables myself! 

However, cooking a quiche the normal way means that there are lots of calories, cholesterol and fat which I don’t want.

Instead of using whole eggs, like a regular quiche, this delicious crustless quiche omits the yolks and uses only egg whites. It is packed with vegetables to give you a breakfast option that is lower in calories and much more healthy.

Best of all, since it has no crust, it makes the recipe gluten free, as well!

Starting the day with a healthy breakfast sets you up for all sorts of positive effects, including weight control and better mental performance throughout the day.

This egg white quiche is very easy to make.

You only need to take one look at the vegetables going into this healthy crustless quiche recipe, to see it is not only a feast for your eyes, but your stomach too.

Baby spinach, roasted red peppers and colorful gourmet cherry tomatoes add both texture and color.Onions, egg, baby tomatoes, spinach and baby tomatoes on a counter top.

Roasting the peppers gives them a sweet flavor.

Start by roasting some red peppers. To roast them in the oven, bake them for 30 minutes at 350 º F.  (You can do this the night before if you wish.)

Roasting the red peppers brings out their natural sweetness and adds a lovely flavor as well as a vibrant color to the quiche. See my tutorial for other ways to roast red peppers here.Roasted red peppers with charred spots on a white plate.

Next, cook the onion and garlic in a pan that has been sprayed with Pam until the onion is tender. I let the onions caramelize a little to give them some color.

Add the garlic after the onions are softened, but be sure not to cook them too long or the garlic will burn.

While the onions are cooking, steam the spinach in the microwave and squeeze out the moisture so the quiche will not be watery.

Beat together the egg whites, milk and cheese, then stir in the cooked onion and garlic.

I chose Gruyere cheese because it is full of flavor and adds a great taste to this spinach and egg white quiche.Egg white cheese mixture in a bowl with whisk, near some Gruyere cheese.

Now it’s time to add some fresh herbs. Almost every recipe that I make has fresh herbs in it. Herbs are super easy to grow and add so much flavor.

Today, I chose rosemary, oregano and thyme.Fresh thyme, oregano and rosemary on a counter.

Layer the spinach and cherry tomatoes in a prepared quiche pan. Take care to arrange the layers to make the most of the color. Carefully pour the egg white mixture over the layers.

I put the majority of the tomatoes and spinach on the bottom layer. Then I added the eggs and topped them with a few more pieces of spinach, some tomatoes and the red peppers.

I love the way the yellow tomatoes adds some “yolk color” even though the quiche is made only from egg whites!  This tasty quiche recipe gets cooked for 50-55 minutes.

When is the egg white quiche recipe done?

Variations on the healthy quiche recipe

Feel free to play around with the vegetables and choice of herbs. Some ideas for changing the ingredients in this low calorie quiche:

  • You can use squash to give you a different color of vegetables.
  • Mushrooms would work well to give an earthiness to the quiche.
  • Zucchini adds more green color and lots of nutrients.
  • Switch out the herbs and use sage and chives for a more oniony taste.
  • If you want a bit more protein add in some cooked bacon or lean sliced ham.

Whatever vegetable or herb you happen to have on hand in your crisper drawer right now will probably work just fine.

Eggs vs egg whites – making a quiche more healthy.

A traditional quiche made with whole eggs can be very calorie heavy. Most of the calories in a quiche come from the eggs, and most of the calories in eggs come from the egg yolk.

Using lots of egg whites, in place of whole eggs, gives you the volume you are looking for, and a tasty egg flavor, but with far less calories, cholesterol and fat.Man in a black shirt separating egg yolks from egg whites.

Fresh vegetables make this healthy quiche delicious, nutritious and full of color. What a great way to start your day!

How many egg whites are equivalent to one egg?

One of the most common questions that I get from readers is “how many egg whites equals 1 egg”? The short answer is to use two egg whites for each egg for a traditional serving. This makes an easy swap in terms of volume.

However, If your recipe asks for cups of egg whites, you’ll likely find that 8 egg whites are equal to 12 egg yolks, since they are both 1 cup. This depends on the size of eggs you use, though.eggs in a clear glass in front of eggs and egg shells.

Measuring the whites gives the exact range, but I just find it easier to swap them 2 for 1.

Replacing whole eggs with egg whites will give you less color, since pretty most of the egg color comes from the yolk. This is why I used lots of colorful vegetables in this recipe.

For the health conscious cook, one egg yolk contains close to 200 mg of cholesterol and is loaded with fat, so it makes sense to do the switch from egg yolks to egg whites.

What to do with the left over yolks

This recipe is expensive if you don’t do something with the yolks that are left over. Here are a few ideas for using them:Egg yolk in a shell.

This high protein recipe is low in carbs, sugar and cholesterol. It’s the perfect breakfast for anyone watching their weight who still wants a lot of flavor in the meal.

Saving time in the morning on the crustless quiche recipe.

This recipe can take quite a while to prepare, since it involves roasting the peppers and allowing the quiche to cook and set.

To save time, you can be prepare the quiche the day before, or roast the peppers the night before, and cook the quiche the next morning.

You can also char the peppers over a gas grill, or a gas stove to save time. Bottled roasted red peppers are available from most stores and can be used instead of fresh. However, the flavor is not as delicious as those that are freshly roasted.

I have made this twice with some leftover egg whites I had. I basically cleaned out leftover veggies in the fridge and added some mozzarella cheese to the recipe. It was a hit with both my husband and my daughter (a very picky 17 year old). This was perfect and I will be making it often. It's lovely for breakfast or a light lunch.

do you think it would be OK to leave out the milk? I don't drink milk but would still like to try this recipe out.

I don't recommend this. Any changes you make to a recipe will affect how it tastes. It needs something to bind all the ingredients together, or you will basically have scrambled eggs in a pan.

Hi there, in the midst of making this and am looking forward to it coming out of the oven! Can you reheat it in the microwave? Also, how many serves to this dish?

This is delicious. I used 4 whole eggs, since I eat the yolks for the choline and vitamin D. When it comes out of the oven, it looks like it has a crust. It looks great too. It's a very versatile recipe, so have fun trying different ingredients. I also tried broccoli and cheddar with tomato slices on top. Awesome.
