  • 1/4 cup green bell pepper Finely diced
  • 1/4 cup onion Finely diced
  • 1 jar diced pimentos 4 oz, drained

Equipment

Method
 

  1. Boil chicken in a large pot of water until cooked through, about 30 to 45 minutes. Let it cool and shred into small pieces. Reserve 2 cups of the broth.
  2. Bring the reserved broth to a boil and cook the spaghetti in it until just al dente. Drain and set aside.
  3. In a large bowl, combine cooked spaghetti, shredded chicken, soup, green pepper, onion, pimentos, 2 cups of cheddar cheese, seasoned salt, cayenne pepper, and black pepper.
  4. Slowly add the chicken broth. Stir until creamy but not too wet. Adjust seasonings to taste.
  5. Transfer mixture to a greased casserole dish and sprinkle remaining 1 cup of cheddar cheese on top.
  6. Bake at 350°F for 35 to 45 minutes until hot and bubbly. Cover with foil if the cheese browns too quickly.

Notes

You can prepare this casserole ahead of time and refrigerate for up to two days or freeze for up to six months. Thaw overnight before baking. For extra flavor, use a mix of cream of chicken and mushroom soup.
