What is Crustless Quiche?
I have a big love relationship with quiche, and in particular, crustless quiche. Think of crustless quiche as egg bake or egg casserole that’s a bit lighter than quiche because, aside from not including a heavy crust, you can use milk as opposed to heavy cream. Plus, obviously, since we’re not making a crust here, it’s easier and quicker to make.
Crustless quiche is one of those foods that are fancy and, at the same time, so deeply practical. And it’s a great way to use up those veggies forgotten in the back of the fridge. Case in point, today’s crustless zucchini quiche.
This simple zucchini quiche recipe came about at the tail end of a long week–when I’d run out of ingredients but one lone zucchini, a tomato, and some shallots. Talk about turning a few humble ingredients into a wholesome meal, eh?!
Why this curstless zucchini quiche works
This zucchini quiche starts with sauteing zucchini slices along with shallots in extra virgin olive oil. This rids us of zucchini moisture, while already building flavor as the zucchini browns and the shallots caramelize nicely.
The cooked zucchini and shallots also serve as the “crust” lining the bottom of my quiche dish, because here, I don’t even bother making pastry. Still, I augmented the egg mixture with just a little bit of white wheat flour, so we still get a hearty quiche without the crust. Throw in some fresh parsley, or your favorite fresh herb, for a little flavor lift.
Now, as you would expect, this crustless zucchini quiche does utilize some cheese. I kept things light by using only 1/2 cup part-skim mozzarella and a sprinkle of Parmesan.
What to serve with this crustless zucchini quiche
I like to serve this zucchini quiche with a bright, flavor-packed Mediterranean salad (or two) next to it. My first choice here is Balela salad because it is a more substantial salad with loads of chickpeas. But a few other options: Fattoush Salad; Tabouli; 3-ingredient Mediterranean salad; and Orange and Pomegranate salad.
A couple more notes on this zucchini quiche
This recipe is quite forgiving, and you can make it your own by adding in a handful of leafy greens like spinach, for example, or try different veggies according to what’s in season.
If you’re into meal prep, you can make this crustless zucchini quiche a few days ahead and refrigerate. Simply reheat a slice or two as needed (or eat it cold, which I really enjoy!)

Description
Simple crustless zucchini quiche recipe with fresh herbs, tomatoes, and shallots. Perfect for breakfast, lunch, or a light dinner.
Ingredients
- 1 medium tomato sliced into thin rounds
- Private Reserve extra virgin olive oil
- 1 zucchini, sliced into rounds (about 8 ounces sliced zucchini)
- 3 shallots, sliced into rounds (about 3.5 ounces sliced shallots)
- Kosher salt and pepper
- 1 tsp sweet Spanish paprika, divided
- 1/2 cup part-skim shredded mozzarella (nearly 2 ounces)
- 2 tbsp grated Parmesan (about 0.35 ounces)
- 3 large eggs, beaten
- 2/3 cup skim milk
- 1/4 tsp baking powder
- 1/2 cup white whole wheat flour OR all-purpose flour (about 2 ounces), sifted
- 1/4 cup packed fresh parsley (about 0.2 ounces)
Instructions
- Preheat the oven to 350 degrees F.
- Arrange sliced tomatoes on paper towel and sprinkle with salt. Leave for a few minutes, then pat dry.
- Meanwhile, in a large cooking skillet, heat 2 tbsp Private Reserve extra virgin olive oil over medium heat until shimmering but not smoking. Add zucchini and shallots. Season with kosher salt, pepper, and 1/2 tsp sweet paprika. Raise heat slightly, and sautee, tossing regularly, until vegetables are tender and nicely colored (with some brown spots on zucchini).
- Transfer the cooked zucchini and shallots mixture to the bottom of a lightly oiled 9-inch pie dish like this one. Arrange sliced tomatoes on top. Add mozzarella, and Parmesan (spread evenly across).
- In a mixing bowl, whisk together eggs, milk, remaining 1/2 tsp paprika, baking powder, flour, and fresh parsley.
- Pour egg mixture into the pie dish on top of the cheese mixture.
- Bake in 350 degrees F heated-oven for about 30 minutes or until the egg mixture is well set in the dish. Remove from oven and wait 5 to 7 minutes before slicing to serve (Quiche will puff up slightly because of the baking powder, but will quickly go down as it sits.)

OMG! This is so good! I couldn’t find shallots, so I used some yellow onion. It is supposed to be mellow. I also added some oregano (my husband’s favorite). It tasted great!
I’m curious though, does it have to be refrigerated? It looks so pretty on my covered cake plate and it is yummy at room temp, but I don’t want to be unsafe.
Thanks so much for all your scrumptious recopies!
So glad to hear it, Elsa. I’m not sure I fully understand what you’re asking, but I’m assuming you mean the leftovers? If so, yes, leftovers need to be refrigerated.
I just made this for dinner. It was absolutely amazing. I added a bit of thyme and used goat cheese instead of parmesan because I love the zucchini & goat cheese combo.
Next time I will use parmesan. Thank you for the recipe! I love making quiches and I never imagined a crustless one could be so good.🤤
Appreciate & Love your delicious recipies.
I have milk/lactose intolerance.
What ingredient can i use instead to make
your quiche?

thank you, Meg! So glad you liked it!
Another fantastic recipe! My husband and I have been cooking them together instead of the delivery meal kits.
We added portobello to the zucchini and shallot mixture as we had some on hand and that gave an additional depth to the overall flavor.
Funny enough, when we were done with the meal husband says, “I didn’t think I would like that but I loved it!” He makes me laugh.
I’m looking forward to trying this!
Just wondered what happens to the other half teaspoon of paprika?
Awesome! And good catch re paprika…the remaining 1/2 tsp paprika goes in the egg mixture. Enjoy!
can I use feta cheese instead of mozzarella?
Sure, Monique! I think that would work
Only 3 eggs for 8 servings? Can I make this with more eggs?
You can add an egg, but you really don’t need to. There is flour and milk etc.
This looks wonderful, but do I have to add the flour?
The flour helps keep the quiche consistency. But it’s possible to elminate and make something more like a frittata. Here’s another zucchini baked omelet: https://www.themediterraneandish.com/middle-eastern-zucchini-baked-omelet-eggah/ And here is a frittata recipe: https://www.themediterraneandish.com/feta-spinach-frittata-recipe/
Can this be made in a microwave
I haven’t tried that, honestly.
I love to make quiche for breakfast, lunch or supper- they’re so versatile! And theincredients here are yummy in the summer! Thanks for sharing!
