How to Make Chicken Zucchini Bake
Step 1: Prepare the Chicken and Zucchini
Start by preheating your oven to 375°F (190°C) and lightly greasing your casserole dish to prevent sticking. Next, slice your chicken breasts into bite-sized chunks or 1-inch strips, seasoning them generously with salt, pepper, garlic powder, and onion powder to lock in flavor. Meanwhile, slice the zucchinis into tidy ¼-inch rounds that will cook perfectly in the bake. This prep sets the foundation for a dish bursting with both texture and flavor.
Step 2: Make the Sauce and Cook the Chicken
Heat olive oil in a skillet over medium heat and cook the seasoned chicken for 5-7 minutes until it’s beautifully browned and cooked through. Set the chicken aside, then quickly sauté minced garlic in the same pan for a fragrant kick. Mix together sour cream or Greek yogurt, grated Parmesan, half of your mozzarella, oregano, basil, and a bit of salt and pepper in a bowl until smooth and creamy. This sauce will be the luxurious heart of your casserole.
Step 3: Assemble the Casserole
Spread zucchini rounds evenly on the bottom of your greased baking dish, creating a lovely green base. Layer the cooked chicken over the zucchini, then smother everything with your creamy sauce mixture. Finally, sprinkle the rest of the mozzarella and cheddar cheeses on top to guarantee a golden, bubbly finish once baked.
Step 4: Bake the Chicken Zucchini Bake
This baking step is where the magic happens—Bake the Casserole: Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly, and the zucchini is tender. The cheese will develop beautiful golden spots while the zucchini softens just enough to melt into the layers of flavor beneath. It’s hard to resist that inviting aroma coming from your oven as it transforms this simple dish into a comfort food delight.
How to Serve Chicken Zucchini Bake

Garnishes
A sprinkle of fresh parsley on top adds a pop of vibrant green and fresh flavor that complements the rich, cheesy bake perfectly.

These small additions elevate the dish from simple to stunning in just moments.
Side Dishes
