Ingredients
  

  • 1/2 cup chopped onion
  • 1 cup chopped celery about 1 bunch celery
  • 1 cup diced carrots, optional
  • 2 tablespoons unsalted butter or substitute with olive oil
  • 3/4 cup chicken broth
  • 4 tablespoons low sodium soy sauce
  • 4 cups cooked boneless chicken breast halves cut into bite size pieces (or rotisserie chicken)
  • 2 cans cream of mushroom soup or substitute with cream of chicken soup for added flavor
  • 3 cups cooked white rice
  • 1 large 5 oz can of chow mein noodles we used La Choy
  • 1 cup unsalted cashew halves and pieces we used Planters, reserving some for topping
  • Optional garnish: sliced green onions

Instructions
 

Sauté Vegetables:

  • Preheat oven to 350°F. In a large saucepan, melt butter or heat olive oil over medium heat. Sauté onion, celery, and carrots until softened, about 5-7 minutes.

Mix Ingredients:

  • In a large bowl, combine the chicken, sautéed vegetables, cream of mushroom (or cream of chicken) soup, chicken broth, and soy sauce. Add cooked rice and gently mix everything together.

Assemble Casserole:

  • Grease a 9x13 casserole dish and spread the mixture evenly in the dish. Top with chow mein noodles and sprinkle cashews over the top, reserving some for after baking if desired.

Bake:

  • Bake for 20-25 minutes or until edges are golden brown and the topping is crispy.

Garnish and Serve:

  • Remove from oven, garnish with extra cashews and sliced green onions if desired, and serve warm. Enjoy!

Notes

Substitutions:
    • Butter/Oil: The unsalted butter can be substituted with olive oil for a slightly lighter taste.
    • Soup: You can use cream of chicken soup instead of cream of mushroom for a richer, chicken-forward flavor.
    • Chicken: Rotisserie chicken is a quick substitute for cooked chicken breast if you’re short on time.
  • Make-Ahead Tip: This casserole can be assembled up to a day ahead. Cover and refrigerate, then bake when ready to serve.
  • Storage and Reheating: Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat, cover with foil and warm in a 350°F oven until heated through.
  • Serving Suggestion: Garnish with freshly sliced green onions for a pop of color and flavor. Serve alongside a simple green salad or steamed vegetables for a balanced meal.
