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.



Comments & Reviews
Deborah says
This was very good, easy, and enjoyed by the entire family! Thank you for a great and simple recipe! The spice mixture was delicious! I did add a 15oz can of diced fire roasted tomatoes as suggested by another reviewer for additional color and texture, and it worked well. The liquid from the zucchini and the tomatoes created a lovely “sauce” to spoon over the jasmine rice that I made on the side. ❤️
Virginia says

Very flavorful. But I am going to try marinating it a little longer.

Excellent quick meal! I added fresh garlic instead of powdered, otherwise followed it exactly for a triple batch! We put it over rice and had watermelon as a side.

This is delicious and I have made it three times since I found the recipe. Everyone in the house likes it which is rare.

Really good flavor and chicken was tender. Would sauté the veiggies first next time. I added cherry tomatoes, too. Delicious!

Family enjoyed. Cooked it right after it was seasoned due to time. Would make it again but either turn down the temp or take out before 30 mins .
Vinny says

Tried it today. Changed it just a little bit by adding bell peppers and 1/2 teaspoon of sugar to brighten the sauce. I chose to garnish with chopped cilantro and diced scallion greens. Over rice was perfect! My husband and family enjoyed it very much. Thank you.
Dana says
I sautéed my Chicken, added squash and home grown tomatoes, shredded parmesan cheese and lemon juice, over jasmine rice. My family loved it. Will definitely be making again.
Amy says
Would you be able to freeze this?
Dayna Jankowski says
Absolutely! Once cooled, place the cooled chicken and zucchini recipe in a freeze-safe container. Freeze for 2-3 months.
Caitlyn says
Loved this recipe! Incredibly easy and SO flavorful! I used smoked salt instead of smoked paprika and an Italian herb blend instead of oregano because that’s what I had. I also marinated it for about 24 hours all together in the fridge. Will definitely be adding this to the meal rotation!
