Ingredients You’ll Need

These ingredients work beautifully together to create a casserole that’s creamy, cheesy, and just the right amount of savory, while the zucchini keeps it fresh and light. When shopping, try to pick firm zucchinis without soft spots, and use good-quality cheese to really make this dish sing.

• Zucchini: Choose medium-sized ones for the best texture—too big and they get watery.
• Cooked Chicken: Rotisserie chicken works wonders here to save time, but leftover cooked chicken is perfect too.
• Sour Cream: Adds creaminess and a slight tang that balances the richness.
• Garlic Powder: Gives an easy, mellow garlic flavor without overpowering.
• Onion Powder: Compliments the garlic and adds depth.
• Kosher Salt: Enhances all the flavors naturally.
• Black Pepper: Freshly ground if possible—that little bit of heat brightens things up.
• Mozzarella Cheese: Melts beautifully and gives that stretchy, gooey texture.
• Parmesan Cheese: Adds a sharp, nutty flavor that rounds out the cheese blend perfectly.

Variations

One of the things I love most about this Cheesy Chicken Zucchini Casserole Recipe is how adaptable it is. Over time, I’ve added different ingredients based on what’s in my fridge or what my family craves, and it always turns out great. Feel free to make it yours with these ideas!

• Add Veggies: I’ve tossed in sliced mushrooms or chopped bell peppers for extra color and flavor—especially when zucchini is a bit scarce or I want more variety.
• Spice it Up: When my family wants a little heat, I sprinkle in chili flakes or smoked paprika, which really wakes up the dish.
• Make it Heartier: Throwing in cooked rice or pasta transforms it into a full meal, perfect when you want something filling without extra sides.
• Dairy-Free Option: Use a dairy-free sour cream and vegan cheese blends; just know the flavor profile shifts but still delicious and comforting.

How to Make Cheesy Chicken Zucchini Casserole Recipe

Step 1: Prep Your Zucchini and Chicken

Start by chopping your zucchinis into bite-sized pieces so they cook evenly and blend nicely into the casserole. If you’re using rotisserie or leftover chicken, make sure it’s shredded or chopped into small pieces—the key here is even cooking and easier mixing. Pro tip: I like to pat the zucchini pieces dry with a paper towel to avoid extra moisture that can make the casserole watery.

Step 2: Mix It All Up

Grab a large bowl and toss together the zucchini, chicken, sour cream, garlic powder, onion powder, salt, and pepper. Mix until everything is well coated—this ensures every bite has that lovely seasoning and creaminess. Trust me, don’t skip mixing — it really unifies the flavors.

Step 3: Layer and Bake

Transfer the mixture to a greased 9×13-inch baking dish and smooth out the top. Then pour over the shredded mozzarella and sprinkle the Parmesan evenly on top. Cover the dish tightly with foil to keep the moisture in, then bake at 375°F for 20 minutes. After that, remove the foil and bake for another 10 minutes until the cheese is golden, bubbly, and irresistibly inviting. Let it rest for about 5 minutes before serving—this helps everything set up and makes it easier to serve.

How to Serve Cheesy Chicken Zucchini Casserole Recipe

Garnishes

I usually add a sprinkle of fresh chopped parsley or basil on top—this fresh green touch adds brightness and a pop of color that looks as good as it tastes. Sometimes a little crushed red pepper flakes if we want a tiny kick. It really dresses up the plate without extra effort!

Side Dishes

To keep things balanced, I love pairing this casserole with a crisp side salad or some roasted veggies. Garlic bread is also a crowd-pleaser if you’re after something a bit heartier. And honestly, because it’s packed with chicken and veggies, it can easily stand alone as a full meal too.

Creative Ways to Present

Once, for a family gathering, I baked individual portions in small ramekins and topped each with a sprinkle of extra cheese and herbs. It was such a fun and elegant way to serve this humble casserole, and everyone loved having their own personalized dish!

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge and find they keep beautifully for about 3 days. The flavors even deepen overnight, making for an even tastier next-day meal.

Freezing

This casserole freezes well too! I portion it into freezer-safe containers and it keeps for up to 3 months. When I’m short on time, I love pulling a container out to thaw in the fridge overnight and bake fresh the next day.

Reheating

To reheat, I pop leftovers into a 350°F oven covered with foil to keep it moist, about 15-20 minutes or until warmed through. This helps preserve the cheesy texture and prevents it from drying out or getting rubbery like microwave reheating can sometimes do.
