Recipe FAQs
For a Whole30-approved meal, serve this dish with fluffy quinoa. On the other hand, buttery rice or a nice fresh salad will also work.
This time around, I served this dish with jasmine basmati rice. It was spectacular!
Cover leftovers with a lid or foil and place them in the fridge for up to three days.
Chicken is done cooking when it reaches an internal temperature of 165 degrees F. Therefore, making this Easy Baked Chicken and Zucchini recipe will take about thirty minutes in the oven at 425 degrees F.
While metal does heat up faster than glass, I prefer glass when making a chicken dish like this and metal when baking desserts.
The marinade is key to this recipe as it soaks into the chicken and keeps it from drying out while it is cooking. You can marinate the chicken for up to twenty-four hours before baking it.

I added halved cherry tomatoes and a dollop of sour cream before marinading, then topped with grated Parmesan before baking. Served over tri-color quinoa – very tastey! Thanks for sharing 🙂

I took frozen chicken strips thawed and cut up I cooked three pieces of bacon, then took the onion and some bell pepper and the chicken it browned in the bacon grease added it to the bowl . After baking my family was impressed with it. They want this again!

I added vegan mayonaise, and it give it a very creamy crunchy texture . I also sprinkled dairy free cheese, and it actually melted.

Delicious dish! This is a great basic dish that you can add anything to and change the flavor. I did add mushrooms, a can of stewed tomatoes and some Italian seasonings. This is a keeper!

Do you cook the chicken first?
Dayna Jankowski says
On Step 4 it says “Transfer the chicken and veggies to a baking dish and bake it in the oven uncovered at 425°F for 30 minutes.”

Tina Lincoln says
The Baked Chicken and Zucchini is a Wonderful Dish! I was concerned that it looked a little bland, and maybe it would taste that way too. No worries! It tastes wonderful! I like that there is not a lot of other stuff that would add to belly upset. Instead of using the big oven, I used my small on-the-counter oven, so that it would not heat the house up so much, worked great! Thank You for a Great Recipe!
Patti C. says
I just used our first two zucchini squash out of the garden for this recipe today. I didn’t have a whole onion, so I used the half of a red onion that I had in the fridge. Added just a touch more olive oil since I was using two squash. It was amazing! Thank you for a new way to use up squash from the garden. My only complaint? The name that you gave this recipe doesn’t do it justice. We loved it. Thank you again.
