Step-by-Step Guide to Making Chicken and Zucchini Bake

Preparing the Zucchini

Begin by slicing your zucchini into uniform ¼-inch rounds. Place them in a colander set over a bowl or in the sink. Sprinkle generously with salt (about 1-2 teaspoons) and toss to coat all pieces. Let them sit for 15-20 minutes while you prepare other ingredients. You’ll be amazed at how much liquid drains out. After the time has elapsed, pat the zucchini slices thoroughly dry with paper towels or a clean kitchen towel. This step is non-negotiable for a successful zucchini chicken bake.

Seasoning the Chicken

While the zucchini drains, cut your chicken breasts into bite-sized chunks—roughly 1-1½ inch pieces. Place them in a bowl and drizzle with 1 tablespoon of olive oil. Add half of your dried oregano, basil, thyme, paprika, salt, and pepper. Toss well to ensure every piece is evenly coated with the aromatic seasonings. This pre-seasoning step ensures the chicken itself is flavorful, not just the sauce around it.

Sautéing the Aromatics

Preheat your oven to 400°F (200°C). Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and cook for 3-4 minutes until softened and translucent. Add the minced garlic and cook for another minute until fragrant. Remove from heat and set aside. These aromatic vegetables form the flavor foundation of your chicken zucchini casserole.

Layering Your Bake

Grease a 9×13-inch baking dish with the remaining olive oil or butter. Now comes the fun part—layering! Start with half of your zucchini slices, arranging them in overlapping rows across the bottom of the dish. Sprinkle with half of the remaining dried herbs.

Next, distribute half of the seasoned chicken pieces evenly over the zucchini. Scatter half of the sautéed onion and garlic mixture over the chicken. Sprinkle with ⅓ of the mozzarella cheese and a bit of the Parmesan.

Repeat these layers: remaining zucchini, remaining herbs, remaining chicken, remaining onion-garlic mixture, and another ⅓ of the cheeses. Dot the top with small pieces of butter, which will help create a golden, crispy top layer.

The Final Cheese Layer

For that stunning, golden-brown top showcased in the image, reserve the final third of your cheese for topping. About 10 minutes before the bake is done, sprinkle this remaining cheese evenly over the entire surface, along with any remaining Parmesan. The result is that gorgeous, bubbling, golden cheese crust that makes this zucchini chicken bake so visually appealing and irresistibly delicious.

Baking Your Chicken and Zucchini Casserole

Cover the baking dish tightly with aluminum foil. This initial covered baking period (about 35 minutes) allows the chicken to cook through and the vegetables to soften while retaining moisture. The foil traps steam, creating a self-basting environment that keeps everything tender.

After 35 minutes, carefully remove the foil and add your final cheese layer if you haven’t already. Return the uncovered dish to the oven for an additional 15-20 minutes. You’re looking for the chicken to reach an internal temperature of 165°F (74°C), the zucchini to be tender but not mushy, and the cheese on top to be beautifully melted and golden brown with some crispy edges.

The Finishing Touches

Remove your gorgeous chicken zucchini bake from the oven and let it rest for 10 minutes. This resting period allows the juices to redistribute and makes serving much cleaner. Just before serving, garnish generously with fresh chopped parsley and basil. The pop of fresh green herbs against the golden cheese makes the presentation absolutely restaurant-worthy.
