What Ingredients are in Cheesy Chicken Zucchini Casserole?

- 2 medium zucchini, chopped
- 2 cups cooked chicken (shredded or chopped)
- ½ cup sour cream
- 1 teaspoon garlic powder
- 1 teaspoon onion powder

How to Make this Cheesy Chicken Zucchini Casserole
Making this casserole is wonderfully straightforward, perfect for those busy weeknights when you want something homemade without the fuss. Start by preheating your oven to 375°F and greasing a 9×13 baking dish—this prevents sticking and makes cleanup so much easier, which we can all appreciate after a long day.
In a large mixing bowl, combine 2 medium chopped zucchini and 2 cups of cooked chicken with ½ cup of sour cream. The sour cream creates that creamy, luxurious texture that makes casseroles so comforting. Then add your seasonings: 1 teaspoon garlic powder, 1 teaspoon onion powder, ½ teaspoon kosher salt, and ¼ teaspoon black pepper. These simple seasonings really bring the dish to life without overwhelming the natural flavors of the chicken and zucchini.
After mixing everything thoroughly, spread this mixture evenly in your prepared baking dish. For best results, consider using a high-quality dish from a premium cookware set that distributes heat evenly. Now comes the best part—cheese! Sprinkle 1 cup of shredded mozzarella and ½ cup of grated Parmesan over the top. Cover the dish with foil and bake for 20 minutes, which allows the zucchini to soften and the flavors to meld together. Then, remove the foil and bake for an additional 10 minutes until the cheese turns beautifully golden and bubbly around the edges.
Remember to let the casserole cool for about 5 minutes before serving—it’s tempting to dig right in, but this brief rest allows the casserole to set up nicely and makes it easier to serve neat portions.
What to Serve with Cheesy Chicken Zucchini Casserole
While this cheesy chicken zucchini casserole stands perfectly well on its own as a complete meal, pairing it with complementary sides can transform your dinner into something truly special.
I love serving a crisp green salad with a light vinaigrette to balance the rich, creamy texture of the casserole. Garlic bread or dinner rolls make perfect companions for sopping up any extra sauce.
Need more veggies? Roasted asparagus or steamed broccoli add nutritional value and beautiful color contrast on your plate. For a heartier option, consider a side of quinoa or brown rice.
What’s your favorite side dish combo? The versatility of this casserole makes it a weeknight winner.
Leftovers and Storage for this Cheesy Chicken Zucchini Casserole
One of my favorite things about this cheesy chicken zucchini casserole is how beautifully it stores for future meals. Once cooled completely, pop it in an airtight container and refrigerate for up to 4 days. The flavors actually develop overnight, making day-two casserole somehow even tastier, if you can believe it.
For longer storage, portion it into freezer-safe containers and freeze for up to 3 months. To reheat, thaw overnight in the fridge, then warm in a 350°F oven until heated through, about 15-20 minutes.
Cheesy Chicken Zucchini Casserole Substitutions and Variations
This casserole shines with flexibility, allowing you to swap ingredients based on what’s hiding in your fridge. No chicken? Try ground turkey or even chickpeas for a vegetarian twist. Yellow squash works beautifully instead of zucchini, or go wild with a mix of both.
Not a fan of mozzarella? Cheddar, provolone, or Mexican blend cheese step in perfectly. You can even spice things up with jalapeños or red pepper flakes if you’re craving heat. Adding breadcrumbs on top creates a delightful crunch, while fresh herbs like basil or thyme elevate the flavor profile.
Final Thoughts
After exploring all those creative variations, I’ve got to say that the beauty of this Cheesy Chicken Zucchini Casserole lies in its simplicity. It’s one of those reliable weeknight heroes that comes together in minutes but tastes like you spent hours in the kitchen.
What I love most? It’s basically a complete meal in one dish – protein, veggies, and that irresistible cheesy goodness all working together. Can you think of anything more comforting?
Whether you stick to the classic recipe or try one of the substitutions, this casserole is sure to become a family favorite in your home too. If you’re looking for more low-carb alternatives, consider trying recipes with spaghetti squash which offers a similar comfort food experience without the carbs.
