Chicken Noodle Casserole

This Chicken Noodle Casserole is easy to make with canned soup or with my homemade cream of mushroom! It's got a delicious cheese sauce with sour cream, broccoli, and juicy chicken.


  • 2 1/2 cups diced chicken, about 2 small chicken breasts
  • 1 teaspoon Italian Seasoning
  • 3/4 teaspoon Garlic Salt
  • 1/4 teaspoon Pepper
  • 2 tablespoons olive oil
  • 2 cups broccoli florets
  • 3 cups dry Rotini
  • 10.5 oz. cream of mushroom soup, (cream of chicken works well too)
  • 8 oz. sour cream, equal to one cup
  • 1/2 cup milk, any kind
  • 2 cups sharp white cheddar cheese, shredded
  • 1 cup regular cheddar, shredded
  • 1 cup French’s crispy fried onions


  • Preheat oven to 375 degrees.
  • Season the chicken with 1 tsp. Italian seasoning, 3/4 tsp. garlic salt, and 1/4 tsp. pepper.
  • Heat 2 Tbsp. olive oil over medium-high heat. Add the chicken and cook for 3 minutes.
  • Toss the chicken and add the broccoli. Cook for 3-4 additional minutes, until the chicken is cooked through. Remove from heat.
  • Cook the rotini for 1 minute less than al dente, refer to package for cooking time.
  • Meanwhile, add the cream of mushroom soup, sour cream, milk, and 2 cups sharp white cheddar to the pot with the chicken & broccoli. Stir to combine.
  • Drain the pasta and add it to the pot. Use a silicone spatula to gently mix until combined.
  • If the pot isn't oven safe, transfer to a lightly greased 9 x 13 inch casserole dish and add the pasta mixture.
  • Top with 1 cup regular cheddar. Cover and bake for 25 minutes.
  • Remove cover and add crispy fried onions. Bake uncovered for 8 minutes. Serve with Garlic Bread with Cheese.



Using Frozen Broccoli
  • Using a 16 oz. bag of frozen broccoli can also be used. Just be sure you thaw and pat it dry! 
  • Frozen broccoli is already blanched so there's no need to cook it in the pot with the chicken unless you prefer very soft broccoli.
  • Frozen peas, green beans, or carrots make a great addition too. Thaw them out prior to baking or increase covered baking time by 5-7 minutes.

Make Ahead Method
  • Follow assembly instructions and let the casserole completely cool. Cover and refrigerate for up to 2 days. Add 15 minutes to covered baking time. 

  • Store in an airtight container and refrigerate for 3 days or freeze for up to 3 months.
