Ingredients

Scale

Chicken

  • 2 cups cooked chicken, shredded

Pasta

  • 3 cups uncooked spaghetti, broken into 2-inch pieces

Sauce and Vegetables

  • 2 cans cream of mushroom soup
  • 1/4 cup finely diced green pepper
  • 1/4 cup finely diced onion
  • 1 (4-oz) jar diced pimentos, drained
  • 2 cups reserved chicken broth from pot
  • 1 tsp Lawry’s Seasoned Salt
  • 1/8 to 1/4 tsp cayenne pepper
  • Salt and pepper, to taste

Cheese

  • 3 cups grated sharp cheddar cheese, divided (2 cups mixed in, 1 cup for topping)

Instructions

  1. Prepare the Chicken: Cook one whole fryer chicken, then remove and shred the meat to yield about 2 cups of cooked chicken. Reserve the cooking broth for later use.
  2. Cook the Spaghetti: Use the reserved chicken broth to cook the broken spaghetti pieces until they are al dente. Be careful not to overcook the pasta to prevent it from becoming mushy.
  3. Combine Ingredients: In a large bowl, mix the cooked spaghetti, shredded chicken, two cans of cream of mushroom soup, diced green pepper, diced onion, drained diced pimentos, 2 cups of the reserved chicken broth, Lawry’s Seasoned Salt, cayenne pepper, salt, and pepper. Then add 2 cups of grated sharp cheddar cheese and stir until well blended.
  4. Assemble the Casserole: Transfer the mixture into a casserole pan. Evenly spread the remaining 1 cup of sharp cheddar cheese over the top of the casserole.
  5. Bake the Casserole: Preheat the oven to 350°F (175°C). Cover the casserole and bake for 45 minutes or until the mixture is bubbly. If the cheese begins to brown too much, cover the dish loosely with foil to prevent burning.
  6. Storage Options: You can freeze the casserole, covered, for up to six months, or refrigerate it, covered, for up to two days before baking. Bake immediately if preferred for fresh serving.

Notes

  • Use the chicken broth from cooking the chicken to add extra flavor to the spaghetti and casserole mixture.
  • Adjust the amount of cayenne pepper to your preferred level of spiciness.
  • Cover with foil midway during baking if the cheese topping is browning too quickly.
  • This casserole freezes well and can be stored for up to six months, making it great for meal prep.
