What comes to your mind when you see the title of this post? Another boring diet food that has a nice photo? You will have to apologize to this Skinny Zucchini Casserole recipe for thinking that way once you have the first bite.

I promise, it will become one of your favorite summer treats before you realize. You can pair it with fresh shepherd’s salad or cacik, which is a cold dip made of yogurt and cucumber to have the great flavors of summer.

As a child, I remember zucchini was one of the vegetables I didn't enjoy eating. I never refused to eat a meal made by mom, I wasn't that kind of kid. However, there were a few foods that I found really tasteless. I can't even tell you how zucchini has become my favorite summer vegetable now. I LOVE to create recipes with it!

Besides zucchinis, you mainly need 2 eggs and a little cornmeal and breadcrumbs, which will help the grated zucchini hold together. Also, to make this casserole that tasty, you need a little cheese and black pepper.

I used just a few tablespoons of kasar cheese, which is a Turkish type of cheese but mozzarella or parmesan works fine too. If you are a fan of cheese in your casserole recipes, go check out our baked cheesy zucchini too!
