Ingredients

2 cups cooked chicken, shredded

3 cups dry spaghetti, broken into 2-inch pieces

2 cans cream of mushroom soup

2 cups sharp cheddar cheese, grated

1/4 cup green pepper, finely diced

1/4 cup onion, finely diced

1 jar (4 oz) diced pimentos, drained

2 cups reserved chicken broth (from boiling chicken)

1 tsp Lawry’s Seasoned Salt

1/81/4 tsp cayenne pepper

Salt and black pepper, to taste

1 cup additional sharp cheddar cheese (for topping)

Instructions

Boil chicken: Boil a whole fryer chicken until tender. Remove meat, shred, and measure 2 cups. Reserve 2 cups of the broth.

Cook spaghetti: In reserved broth, cook broken spaghetti until al dente. Drain.

Mix ingredients: In a large bowl, combine cooked pasta, shredded chicken, cream of mushroom soup, 2 cups cheddar, green pepper, onion, pimentos, remaining chicken broth, seasoned salt, cayenne, salt, and pepper.

Assemble casserole: Pour mixture into a greased casserole dish and top with remaining 1 cup cheddar cheese.

Bake: Bake uncovered at 350°F (175°C) for 45 minutes or until bubbly and golden. If cheese browns too quickly, loosely cover with foil.

Notes

Freezer-friendly: Assemble the casserole, cover tightly, and freeze unbaked for future use.

Extra creamy tip: Add a splash of heavy cream or sour cream for a richer texture.

Spice level: Adjust cayenne pepper based on your preference—add more for a kick!
