Ingredients You’ll Need
The best part? Every ingredient pulls its weight in flavor and texture, while keeping things simple and stress-free. Let’s take a peek at what you’ll need and why each is absolutely essential for making your Ultimate Chicken Casserole shine.
- Cooked Chicken Breast (3 cups, shredded or chopped): Rotisserie or leftover chicken makes this extra quick and keeps things juicy and flavorful.
- Cooked Egg Noodles (2 cups): These tender noodles absorb just the right amount of sauce and add heartiness to every bite.
- Cream of Chicken Soup (1 can, 10.5 oz): The creamy backbone of the casserole that ties it all together with comforting, savory flavor.
- Sour Cream (1/2 cup): Adds tang and creaminess, making the sauce luscious without overpowering it.
- Milk (1/2 cup): Loosens the sauce for a perfectly scoopable consistency while adding richness.
- Shredded Cheddar Cheese (1 1/2 cups, divided): Melty, sharp cheddar infuses the casserole with bold flavor; some goes inside, some melts on top.
- Frozen Peas (1/2 cup): Adds a pop of sweetness and freshness to balance the richness.
- Frozen Corn (1/2 cup): Sweet, colorful, and a perfect contrast to the creamy base.
- Garlic Powder (1/2 teaspoon): A pinch of this pantry staple brings savory depth.
- Onion Powder (1/2 teaspoon): Enhances and rounds out the flavor of the sauce.
- Salt and Black Pepper (to taste): Don’t forget to taste and season to bring everything together.
- Crushed Buttery Crackers or Breadcrumbs (1 cup): That golden, crunchy finish everyone fights over.
- Melted Butter (2 tablespoons): Helps the topping brown beautifully and adds rich flavor.
How to Make Ultimate Chicken Casserole
Step 1: Get Prepped
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with cooking spray or a little butter—this ensures easy cleanup and that wonderful crispy edge pieces everyone loves. Gather and measure out all your ingredients so you can assemble the Ultimate Chicken Casserole with minimal fuss.
Step 2: Mix the Filling
In a large mixing bowl, combine your cooked chicken, cooked noodles, cream of chicken soup, sour cream, milk, 1 cup of cheddar cheese, peas, corn, garlic powder, onion powder, salt, and black pepper. Stir everything together until it’s deliciously creamy and the ingredients are evenly distributed. You want each scoop to have a good mix of chicken, veggies, and cheese!
Step 3: Layer and Top
Spread this mixture evenly into your prepared baking dish, smoothing the top. Sprinkle the remaining 1/2 cup of cheddar cheese over the casserole for that irresistible cheesy crust. In a small bowl, mix your crushed crackers or breadcrumbs with melted butter, then evenly scatter this buttery topping over everything—it’s going to bake up beautifully golden and crisp.
Step 4: Bake to Perfection
Slide your casserole into the oven and bake for 30 to 35 minutes, or until the top is bubbly and golden brown. The cheesy edges and crisp topping are your signs that it’s ready to come out. Let the Ultimate Chicken Casserole rest for 5 minutes before dishing it up; this gives the sauce time to thicken and makes serving a breeze.
How to Serve Ultimate Chicken Casserole

Garnishes
For a pop of color and freshness, finish your Ultimate Chicken Casserole with a handful of chopped parsley, fresh chives, or even thinly sliced green onions. A sprinkle of cracked black pepper or a pinch of paprika adds just the right finishing touch and makes each plate look as inviting as it tastes.
Side Dishes
This casserole is hearty on its own, but a crisp green salad or easy roasted veggies make perfect partners, adding brightness and crunch. Fluffy dinner rolls or warm garlic bread are ideal for soaking up every bit of the creamy sauce—don’t forget them!
Creative Ways to Present
For potlucks or parties, scoop the Ultimate Chicken Casserole into small ramekins or individual baking dishes for adorable personal servings. Or, try baking it in a cast-iron skillet for rustic charm. If you love a touch of heat, serve with a bottle of hot sauce or a side of pickled jalapenos for everyone to jazz up their own plate.
Make Ahead and Storage
Storing Leftovers
Leftovers will keep well covered in the fridge for up to 4 days. Store the Ultimate Chicken Casserole in the original baking dish or transfer it to an airtight container. The flavors often deepen after a day, making the leftovers even cozier for lunch!
Freezing
Ultimate Chicken Casserole is freezer-friendly! To freeze, let the baked casserole cool completely, then wrap tightly in a layer of plastic wrap and foil. Freeze for up to 2 months. For make-ahead meals, you can also assemble the casserole without baking, cover, and freeze—just add the cracker topping right before baking.
Reheating
Reheat slices or servings in the microwave for a quick lunch, or pop the whole casserole (uncovered) into a 350°F oven until warmed through, about 20 minutes. If the topping needs to crisp up, broil briefly at the end. Add a splash of milk if it seems a bit dry, and it’ll be good as new!
