Simple crustless zucchini quiche recipe with fresh herbs, tomatoes, and shallots. An egg casserole that is perfect for breakfast, lunch, or light dinner. Add your favorite salad to go along (I have some ideas for you below.)
Be sure to check out my tips and watch the video for how to make this crustless quiche recipe toward the bottom of this post!
What is Crustless Quiche?
I have a big love relationship with healthy 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!)

Crustless Zucchini Quiche Recipe
- Total Time: 45 minutes
- Yield: 8 slices 1x
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.)

I have made this so many times. It so easy and delicious. Making it again for dinner tonight. Thanks!
This was fabulous!!! Would almond flour work?
Hi, Nancy. It should, but it’s not something we’ve tested before. If you go ahead and give it a try, we’d love to know your thoughts!
Great recipe. I made a few modifications using sound dried tomato, pitted olives, feta and spinach. It was delicious.
Made this crust less zucchini quiche for dinner last night, adding chopped cooked spinach on top of the tomatoes, and cooked mild Italian Sausage 1lb. on top of everything. I’m thinking of making it again with bite sized cooked grilled chicken next time for different flavors. Someone else added mushrooms, and I think maybe bite-size steamed broccoli would be good with the chicken. Lovely healthy way to use our homegrown zucchini!!
Have made this dish several times, and it is consistently delicious!
This time, I added mushrooms, because I love them! Yum!
This is another great recipe! Had for dinner last night and am enjoying for breakfast this morning. I made a note to try with smoked paprika next time.
Instead of zucchini I used fresh asparagus from my garden and it was delicious!!
Mmm! Fresh asparagus is the BEST asparagus. If you loved this, you should also check our our newer Asparagus Quiche recipe (this one has a crust). 🙂
Followed exactly and it was SO good. I’ll be adding this to the breakfast prep rotation!
Awesome! Thanks, Al!
Great summer recipe. Lighter than a quiche with crust. Great to play around with different herbs on hand.
Made this tonight based upon having most of the ingredients and I substituted a few for what I had on hand. Really good enjoyed it! Thank you for the recipe🙂
I loved this! I had no problems with any of the inredients.
It tasted ok but the flour and baking powder were clumpy. Will not be trying this one again 😕
Not sure why everyone raves about this recipe. I thought it was pretty bad, mainly I think due to the flour and baking soda, both odd ingredients for a quiche. I was sorely disappointed after going through all the trouble of making it.
What are the dimensions of the pie dish please? I have a pyrex 30 cms dish will this work?
sorry just realise you say a 9″ pie dish. will i have to increase the ingredients?
Welcome your advice. Thanks
Standarad 9″ pie dish is what I use here.You can try a square pyrex dish.
Made this tonight for dinner, it was scrumptious! Looking forward to lunch time tomorrow, so we can eat the rest 🙂
This is the second thing I make from this site and it is wonderful. Great recipe! I am gluten free so I substituted the flour with a mix of rice/potato flour and it worked well.
Thank you for sharing, Gaby! So glad you enjoyed it!
