How to Make Garlic Parmesan Chicken Casserole Recipe
Step 1: Prepare the Baking Dish and Oven
Start by preheating your oven to 350ºF and lightly spraying a 9×9-inch baking dish with cooking spray. This ensures that your casserole won’t stick and helps with an even bake.
Step 2: Mix the Chicken and Creamy Ingredients
In a large bowl, combine the cooked chopped chicken, Lipton Savory Herb with Garlic Soup & Dip Mix, sour cream, cream of chicken soup, and ¼ cup of grated parmesan cheese. Mix everything thoroughly so that the flavors are evenly distributed and the mixture is smooth.
Step 3: Assemble the Casserole
Spread the creamy chicken mixture evenly into the prepared baking dish. This layer forms the hearty base of your casserole.
Step 4: Create the Crunchy Topping
In a separate bowl, mix the crushed croutons with the remaining ¼ cup of parmesan cheese. Sprinkle this evenly over the top of the chicken mixture for that irresistible golden crunch.
Step 5: Bake to Perfection
Bake the casserole uncovered in the preheated oven for 30 to 40 minutes. You’ll want to check for bubbling sauce and a crispy, golden topping. This is when the flavors meld perfectly, and the casserole becomes irresistibly inviting.
How to Serve Garlic Parmesan Chicken Casserole Recipe

Garnishes
A sprinkle of fresh chopped parsley or chives adds a beautiful pop of color and a subtle fresh flavor. A light dusting of extra parmesan right before serving can add that final cheesy flourish.
Side Dishes
This casserole pairs wonderfully with simple green vegetables like steamed broccoli or a crisp salad. Some garlic bread or roasted potatoes can also complement the creamy richness and round out the meal perfectly.
Creative Ways to Present
Serve this dish in individual ramekins for a special touch at dinner parties, or layer it over a bed of cooked rice or noodles to soak up the delicious sauce. Adding a drizzle of garlic-infused olive oil before serving can elevate the presentation and aroma.
Make Ahead and Storage
Storing Leftovers
Store any leftover garlic parmesan chicken casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently to keep the creamy texture intact.
Freezing
This casserole freezes beautifully! Cover tightly with foil or place in a freezer-safe container, and it will keep for up to 2 months. Thaw in the refrigerator overnight before reheating.
Reheating
To reheat, place in a preheated oven at 350ºF for 15-20 minutes or until warmed through. You can also microwave individual portions, but baking helps maintain the crispy topping best.
FAQs
Can I use fresh garlic instead of the soup mix?
Absolutely! Fresh minced garlic can be used for a more pungent and vibrant garlic flavor. Just add about 2-3 cloves finely minced and consider reducing the soup mix to balance seasonings.
Is it possible to make this casserole dairy-free?
Yes, you can substitute sour cream with a dairy-free alternative like coconut cream or a cashew-based cream, and use dairy-free parmesan or nutritional yeast. Keep in mind the texture might vary slightly.
Can I use rotisserie chicken?
Rotisserie chicken is perfect for this recipe—it’s already cooked, flavorful, and easy to shred, making the preparation super convenient.
What can I substitute for croutons in the topping?
If you don’t have croutons, crushed crackers or panko breadcrumbs mixed with parmesan can provide that crunchy topping you want.
How spicy is the Garlic Parmesan Chicken Casserole Recipe?
This casserole is mild and creamy with savory garlic and parmesan notes, making it family-friendly and suitable even for those sensitive to spice.
