What makes it the best skinny zucchini casserole recipe?

Unlike our former casserole, this baked zucchini casserole doesn’t have a golden crust on the top. I didn’t use any breadcrumbs or cornmeal for topping this time. I just prepared a simple mixture of plain yogurt, flour and egg and layered shredded zucchini in a baking pan with it.

In addition, I used 2 eggs in the former casserole and it was ok, but I wanted to try this one with 1 egg. I didn’t mix it with grated zucchini, I added it in the yogurt mixture. I wasn’t sure at the beginning whether it would be enough to hold the ingredients together as I wanted to serve it in squares. It was pretty enough as you can see in the pictures.

As for the amount of flour, I added just 2 tablespoons. I used all-purpose flour, but you can use flour of your choice. If you are following a gluten-free diet, you can use rice flour or corn meal or any other gluten-free flour on hand. Yogurt will do the work, so it doesn’t matter.

Another thing that makes this zucchini casserole recipe skinny is that it doesn’t have any butter or oil. Just very little to grease the casserole pan. Trust me you won’t miss butter or oil at all. On the other hand, black pepper is a must for me when making a casserole with zucchini. And it doesn’t have anything to do with calories, right? Use generous amount of it.

How to make this low-calorie zucchini casserole

There is something I need to warn you about the recipe. You should squeeze the grated zucchini very well. To make this, sprinkle a pinch of salt over grated zucchini, wait for 5 minutes to let it release excessive water and then squeeze in your hands. Otherwise, you end up with a watery or soggy casserole.

So make a layer of grated zucchini, top with shredded mozzarella and yogurt mixture. Make another layer of zucchini and yogurt mixture. Bake it covered for 35 minutes, uncover and top with extra mozzarella. Bake for another 15-20 minutes or until golden.

The mozzarella and yogurt layers inside and on the top make it my best skinny zucchini casserole.
