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!)
