Ingredients

Scale

For the Casserole:

  • 12 oz spaghetti (broken in half)

  • 3 cups cooked chicken, shredded or diced

  • 1 can (10.5 oz) cream of chicken soup

  • 1 can (10.5 oz) cream of mushroom soup

  • 1 cup sour cream

  • 1 cup chicken broth

  • 1½ cups shredded cheddar cheese

  • 1 tsp garlic powder

  • ½ tsp onion powder

  • ½ tsp paprika (optional, for color)

  • Salt and black pepper to taste

For the Topping:

  • ½ cup shredded cheddar cheese (for topping)

  • ½ cup crushed butter crackers or breadcrumbs (optional, for crunch)

  • 2 tbsp melted butter (optional, if using crackers)

Optional Add-Ins:

  • ½ cup diced green bell pepper or pimentos

  • ½ cup sautéed mushrooms or onions

  • ¼ tsp crushed red pepper flakes for a spicy kick


Instructions

Step 1: Cook the Pasta
Bring a large pot of salted water to a boil.
Cook the spaghetti just until al dente—about 1–2 minutes less than package directions.
Drain and set aside.

Step 2: Make the Sauce
In a large mixing bowl, combine cream of chicken soup, cream of mushroom soup, sour cream, chicken broth, garlic powder, onion powder, paprika, salt, and pepper.
Whisk until smooth.
Stir in 1½ cups shredded cheddar cheese and mix well.

Step 3: Assemble the Casserole
Add the cooked spaghetti and shredded chicken to the sauce mixture.
Toss gently until everything is well coated.
Pour into a greased 9×13-inch casserole dish and spread into an even layer.

Step 4: Add the Topping
Sprinkle the remaining ½ cup cheddar cheese evenly over the top.
If using crackers or breadcrumbs, mix with melted butter and sprinkle over the cheese.

Step 5: Bake
Preheat the oven to 350°F (175°C).
Cover with foil and bake for 25 minutes.
Remove foil and bake an additional 10–15 minutes, until hot, bubbly, and golden on top.
Let rest for 5 minutes before serving.

Notes

Use Rotisserie Chicken – Saves time and adds flavor.
Don’t Overcook Pasta – Slightly undercooked pasta holds up best when baked.
Make It Creamier – Add an extra ½ cup of chicken broth or a splash of milk if you like a looser sauce.
Try Different Cheese – Monterey Jack, mozzarella, or a blend work great too.
Double the Recipe – Bake one now, freeze one for later.
