Ingredients You’ll Need

Cooked Shredded Chicken

Use 3 cups of cooked, shredded chicken. You can use chicken breast, dark meat, or a combination of both.

Rotisserie chicken is another convenient option. Remove the skin and bones before shredding.

Condensed Cream of Chicken Soup

You’ll need 1 (10.5-ounce) can of condensed cream of chicken soup.

Use the soup directly from the can without adding water or milk. This keeps the casserole filling thick and creamy.

Sour Cream

One cup of sour cream adds richness and a subtle tang while helping create a smooth chicken mixture.

Cheddar Cheese

Use 1½ cups of shredded cheddar cheese, divided between the two layers. Mild or sharp cheddar can be used depending on your preference.

Butter Crackers

One sleeve of butter crackers, such as Ritz, creates the crunchy topping. Crush the crackers into small, irregular pieces rather than turning them into a fine powder.

How to Make 5-Ingredient Chicken Casserole

Step 1: Prepare the Oven

Preheat your oven to 350°F.

Lightly coat a 9-inch square baking dish with nonstick cooking spray.

Step 2: Mix the Chicken Filling

Add the cooked shredded chicken, condensed cream of chicken soup, and sour cream to a large mixing bowl.

Stir until everything is evenly incorporated and the chicken is coated in the creamy mixture.

Step 3: Create the First Layer

Spread half of the chicken mixture across the bottom of the prepared baking dish.

Sprinkle half of the shredded cheddar evenly over the chicken.

Step 4: Add the Second Layer

Spread the remaining chicken mixture over the first cheese layer.

Top with the rest of the shredded cheddar.

Step 5: Add the Cracker Topping

Evenly scatter the crushed butter crackers over the top of the casserole.

For the crispiest result, add the cracker topping immediately before the dish goes into the oven.

Step 6: Bake

Place the casserole in the preheated oven and bake for approximately 30 minutes.

It is ready when the filling is hot and bubbling around the edges and the cracker topping has turned lightly golden brown.

Step 7: Rest Before Serving

Remove the casserole from the oven and let it stand for about 5 minutes.

This short resting period allows the creamy filling to settle slightly before you scoop and serve it.

Easy Variations

This basic chicken casserole is easy to change without making the preparation complicated.

Add Broccoli

Mix in 1–2 cups of thawed, well-drained broccoli florets for extra color and texture.

Add Peas

Thawed peas can be stirred into the chicken mixture for a simple vegetable addition.

Try Corn

Drained sweet corn adds a little natural sweetness and another layer of texture.

Use Pepper Jack

Replace some or all of the cheddar with Pepper Jack if you want a little more heat.

Try Monterey Jack

Monterey Jack creates a mild, creamy cheese variation that works well with the chicken filling.

When adding vegetables, make sure they are thoroughly drained. Excess moisture can make the casserole filling too thin.

Can You Use Rotisserie Chicken?

Absolutely. Rotisserie chicken is one of the easiest ways to prepare this recipe.

Remove the skin and bones, shred the meat, and measure out 3 cups. You can use white meat, dark meat, or a combination of both.

Can You Use Cream of Mushroom Soup?

Yes. A 10.5-ounce can of condensed cream of mushroom soup can replace the cream of chicken soup.

The overall preparation stays the same, although the finished casserole will have a more pronounced mushroom flavor.

Best Tips for This Chicken Casserole

Keep the Soup Condensed

Do not dilute the cream soup with water or milk. Using it straight from the can helps maintain the thick consistency needed for the casserole.

Drain Added Vegetables Well

If you add broccoli, peas, or corn, remove as much excess liquid as possible before mixing them into the filling.

Don’t Crush the Crackers Too Finely

Small, uneven cracker pieces provide a better contrast between the creamy chicken underneath and the crisp topping.

Add the Topping Right Before Baking

Adding the crushed crackers immediately before baking helps them stay crisp and prevents them from becoming soggy.

Let the Casserole Rest

A five-minute rest after baking makes the casserole easier to serve while keeping the filling warm and creamy.

Make-Ahead Instructions

You can assemble the chicken and cheese layers ahead of time and refrigerate the casserole until you’re ready to bake it.

For the best texture, wait to add the crushed butter crackers until shortly before placing the casserole in the oven. This helps preserve their crispness.

Frequently Asked Questions

Can I use leftover chicken?
