Ingredients

Freshness is key here. Since the seasoning is simple, using ripe vegetables and good quality chicken makes a big difference.

The Main Components

• Chicken Breast – Boneless, skinless chicken breasts cut into bite-sized 1-inch cubes. You can also use chicken thighs for a juicier, more forgiving option.
• Zucchini – You’ll need about 2 medium zucchini, sliced into rounds or half-moons. Leave the skin on for color and texture.
• Cherry Tomatoes – These add a pop of sweetness and acidity. When roasted, they burst and create a natural sauce for the dish.
• Mozzarella Cheese – Freshly shredded low-moisture mozzarella melts best. You could also use Provolone or a sprinkle of Parmesan for extra savory depth.

The Seasoning

• Olive Oil – Use a good quality extra virgin olive oil to coat the ingredients and encourage browning.
• Garlic – Fresh minced garlic is best, but garlic powder works in a pinch.
• Italian Seasoning – A blend of dried basil, oregano, and rosemary.
• Fresh Thyme or Basil – For garnishing at the end. The fresh herbs really brighten up the roasted flavors.
• Salt & Black Pepper – To taste.

Instructions

1. Prep the Ingredients

Preheat your oven to 400°F (200°C). Spray a 9×13 inch baking dish (or a similar sized casserole dish) with non-stick cooking spray or brush lightly with olive oil. Wash and slice the zucchini into 1/2-inch thick rounds. Cut the chicken into uniform cubes.

2. Season Everything

In a large mixing bowl, combine the cubed chicken, sliced zucchini, and cherry tomatoes. Drizzle with the olive oil. Sprinkle with the minced garlic, Italian seasoning, salt, and pepper. Toss everything gently until the chicken and vegetables are evenly coated in the oil and spices.

3. Assemble the Bake

Transfer the mixture to your prepared baking dish. Spread it out into a single, even layer. Try not to overcrowd the pan too much, as this helps the vegetables roast rather than steam.

4. Bake

Place the dish in the preheated oven and bake for 20-25 minutes. The chicken should be cooked through (reaching an internal temperature of 165°F) and the zucchini should be tender-crisp.

5. The Cheesy Finish

Remove the dish from the oven. Sprinkle the shredded mozzarella cheese evenly over the top. If you like a golden crust, you can also add a dusting of grated Parmesan.

6. Melt and Broil

Return the dish to the oven and bake for another 5-10 minutes, or until the cheese is fully melted and bubbly. For those delicious golden-brown spots seen in the photo, switch the oven to “Broil” for the last 2-3 minutes. Watch it closely to prevent burning!

7. Serve

Remove from the oven and let it rest for 5 minutes. The juices will settle, making it easier to serve. Garnish generously with fresh thyme leaves or chopped basil before bringing it to the table.

Chef’s Tips for Success

• Avoid Mushy Zucchini: Don’t slice the zucchini too thin. 1/2-inch slices hold their shape best. Also, avoid overbaking; the zucchini should still have a little bite to it.
• Drain Excess Liquid: Zucchini releases water as it cooks. If you find there is too much liquid in the pan after the initial bake, you can carefully tip the dish to drain some of it out before adding the cheese.
• Spice it Up: Add a pinch of red pepper flakes to the seasoning mix if you like a little heat.
• Meal Prep: You can chop the chicken and veggies ahead of time and store them in the fridge. When ready to eat, just toss with oil/spices and bake.

Serving Suggestions

This dish is a complete meal on its own, but it also pairs well with:

• For Low Carb: Serve over cauliflower rice or with a crisp green salad.
• For Heartier Appetites: Serve alongside roasted potatoes, quinoa, or with a slice of crusty garlic bread to soak up the juices.
