Ingredients

This cheesy zucchini casserole has three layers with:

Shredded zucchini
Grated mozzarella (as much as you want). You can use cheddar too or a combination of both.
Yogurt sauce that is made with thick yogurt, one tablespoon of flour and an egg.

Tip: If you are using dark green zucchinis just like the ones in the picture above, we recommend that you peel all or most of the skin. It gives a bitter taste otherwise.

How To Make

Preheat oven to 375F/ 190C. Lightly brush a small baking pan with olive oil or use a cooking spray for this and put it aside.

First, grate zucchinis. We prefer peeling them as the dark green skin could taste bitter. If you use light green zucchinis, you don't need to peel them.

Then, squeeze the grated zucchinis. Use your hands for this. Take a handful of zucchini and squeeze it in your hands firmly. Measure three cups of squeezed zucchini and put it aside.

Next, in a medium sized bowl, whisk together 1 cup thick yogurt, one egg and one tablespoon of flour until smooth.

Now sprinkle salt and pepper on the zucchini and mix it with your hand so that it is coated evenly.

Then, make the layers:

Place half of the zucchini in the pan, gently press on it with the backside of a spoon.
Sprinkle half of the grated mozzarella over it.
Then pour half of the yogurt sauce all over it.
Place the remaining zucchini over the sauce.
And pour the remaining yogurt sauce.

Bake it for 30-35 minutes until the top is golden. Remove from the oven, sprinkle the remaining mozzarella on the top and bake for another 5 minutes or until the cheese melts.

Serve warm as a side dish or a vegetarian meal. Optionally you can garnish it with fresh herbs when serving.

Alternative Add-Ins

Chicken or ground beef makes a wonderful additions to make this zucchini casserole cheesy and meaty. If you have leftover chicken, chop it into pieces and add it as a separate layer on zucchini. Just don’t use raw chicken as it will release juice and destroy the texture of the casserole. The same is true for beef. Cook it beforehand, then place over the zucchini and continue with the cheese and yogurt sauce.

FAQs

Is This A Gluten-Free Casserole Recipe?

No, it is not because we used one tablespoon of all purpose flour in the yogurt sauce for some consistency. But you can use a gluten-free flour of your choice like rice flour or corn meal or any other gluten-free flour on hand. Yogurt will do the work, so it really doesn’t matter.

Is This A Keto Casserole?

Well, almost. As long as you ignore the carb from that little amount of all purpose flour. If you want to customize this dish for a keto diet, an alternative type of flour is recommended like almond flour or coconut flour. Also you can increase the amount of cheese or add in leftover chicken or ground beef too.

Can I Prepare It Ahead Of Time?

It is not a good idea to make it ahead of time because zucchini is such a juicy vegetable that it releases water as it waits. The best thing is to prepare it and bake immediately. On the other hand, you can bake it for the first 30 minutes and keep it in the fridge. Then you can sprinkle the cheese on the top and reheat it for 5-7 minutes.

Can You Freeze This Zucchini Cheese Casserole?

No, this is not recommended due to the structure of zucchini. It might get soggy after it is thawed and reheated.
