This Skinny Zucchini Casserole recipe is skinny but absolutely not a boring diet food. Even zucchini haters will love this tasty casserole! Serve it for lunch or as a side for dinner. You'll miss it even in winter!

We LOVE vegetarian recipes with zucchini during summer. Cheese stuffed zucchini boats, vegan zucchini tomato casserole and feta zucchini fritters are our summer favorites.

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!

For one thing, it doesn’t contain any oil or butter. I just used ½ tablespoon butter to grease the pan. I used a few simple ingredients for this incredibly yummy zucchini casserole. When someone sees and wants to make this recipe, there is no need to go for shopping. These are some very basic ingredients that I’m sure you always have in your kitchen.

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!

Personally, I feel that black pepper is a must for this recipe. You will agree with me when that very tempting smell of zucchini and black pepper fills in your home when baking. Black pepper is one of the ingredients here which saves this casserole from being boring.

This zucchini casserole recipe is healthy and full of flavor with a wonderful golden crust. I used a combination of cornmeal and breadcrumbs and kasar cheese to have this yummy crust. You can use just cornmeal and leave out breadcrumbs if you have a gluten-free diet.

    The recipe was pretty easy to make. If I made it again, I would definitely cut back on the black pepper and add some other spices (cumin, oregano, cayenne?) as the flavor was a little one-dimensional.
