How to make Chicken Zucchini Casserole
A delicious, healthy and flavorful casserole was NEVER easier to cook up for your crew! Here’s how to make a zucchini casserole:
Preheat
Turn on your oven and spray a pan with cooking spray.
Prepare the Zucchini
Spread out your zucchini slices on some paper towel and sprinkle them with salt. Let them sit for a while, then use another sheet of paper towel to soak up some of the excess liquid.
Assemble
Place the chicken into your prepared pan, sprinkle it with salt, then spread the pesto overtop of it evenly. Arrange the onions overtop of the pesto evenly and then follow with the zucchini slices. Pour the marinara sauce overtop of your casserole, then sprinkle the cheese overtop to finish it off.
Bake
Cover your chicken zucchini casserole recipe with tinfoil and pop it in the oven for 15 minutes. After the timer goes, uncover your casserole and continue baking until it is hot and bubbly and the chicken is fully cooked.
Serve
Serve up your casserole and enjoy! DEVOUR!!

Serving Suggestions
Now that you’ve got a hot and bubbly chicken zucchini casserole, it’s time to serve it to your family and/or guests! This would be delicious served over some hot, cooked brown rice or whichever type of rice you prefer! To make it Keto, consider serving it with cauliflower rice-check out how to make cauliflower rice and pick whichever method your heart desires.
Can you freeze Zucchini and Chicken Casserole?
Often, casseroles are a fantastic make-ahead meal to pop in the freezer to give to a friend when they might need a meal or for those busy weeknights when you don’t have time to cook! In the case of this casserole, though, I would not recommend freezing it as it will likely change the consistency and texture of the zucchini and make it mushy.

I made this following the recipe and it came out delicious! It was very watery even though I soaked up water from the zucchini, but the flavor was great. I served with spaghetti as a side. My family gave it a thumbs up. I will be making this again!
