Tips for the Mediterranean chicken bake recipe
- We cut chicken breasts horizontally to make them thinner and quicker to cook. We count 1 cutlet per serving but it depends on the size of the chicken breasts you have got.
- Add half a teaspoon of Cayenne pepper to the seasoning for a nice kick of heat!
How to serve the chicken bake
If you’ve packed the chicken casserole with veggies, you can serve the Mediterranean chicken bake on its own. Otherwise, we love having the chicken casserole with a crisp salad, on top of couscous, rice, or – if you’d like to stay low-carb/keto-friendly – cauliflower rice.
How to keep the chicken bake leftovers?
You can keep any chicken and zucchini bake leftovers in an airtight container for up to 2 days in your refrigerator. Reheat in the microwave or cover in the oven at 350ºF (180ºC) until heated through.

This was so good! I did have about a 1/2 cup of left over pesto sauce that needed to be used, so I mixed it in with the chicken seasoning. I also liked your idea of serving it over cauliflower rice for an added boost of veggies. It’s a keeper!

Delicious! Made it as stated, and it turned out so good. We will definitely keep this on the rotation as it can be paired with a side salad, broccoli, or even potatoes for a heartier meal.

Very Good! I did add the cayenne pepper as suggested. Extra zucchini and cheese.

Quick, simple, and delicious. We have dietary restrictions in our house so no garlic, onion, or black pepper when we made it. While that would make it far less flavorful for some, given our restrictions, it was still quite tasty. I saw a number of comments about cook time, but I think that really depends on how thick things are. My pieces of chicken were close to 1/4" thick, veggies about the same, and I used quartered cherry tomatoes. After 19 minutes + 2 minutes broiling to brown the cheese, the chicken was fully cooked (avg 160F) and the veggies were "al dente" which is how we prefer them. If my cuts were thicker (1/2" or thicker), cook time would definitely need to be increased. I think if I were to add onions, I might sweat them for a few minutes in a fry pan before adding to make sure they were fully cooked at the end. The next time I make this, I'm considering a 1-3 hour marinade of olive oil, red wine vinegar, lemon juice, oregano, cumin powder, and ground coriander just to add some flavor to the chicken before baking.
