Ingredients

Gather these key ingredients for the classic chicken spaghetti casserole:

Ingredient	Amount
Cooked Chicken	2 cups (about 1 medium fryer chicken)
Spaghetti, dry	3 cups (uncooked, broken into 2-inch pieces)
Cream of Mushroom Soup	2 cans (about 10.75 oz each)
Sharp Cheddar Cheese, grated	3 cups (plus 1 cup for topping)
Green Pepper, finely diced	1/4 cup
Onion, finely diced	1/4 cup
Diced Pimentos, drained	1 jar (4 oz)
Reserved Chicken Broth	2 cups (from cooking the chicken)
Seasoned Salt (e.g., Lawry’s)	1 tsp
Cayenne Pepper	1/8 to 1/4 tsp
Salt and Black Pepper	To taste

Optional additions: Some cooks add bacon on top or adjust spice levels for extra heat and flavor.

How to Make Chicken Spaghetti: Step-by-Step Directions

Cook the Chicken:
Start with a whole fryer chicken cut into pieces. Place it in a large pot of water and bring to a boil. Once boiling, reduce the heat and let it simmer for 30–45 minutes. Cook until the chicken is completely tender and falling off the bone.
- Save the broth for cooking the spaghetti and for the casserole mixture.
Prepare the Spaghetti:
Remove the chicken and strain the broth. Bring the broth back to a boil and cook the broken spaghetti pieces until just al dente—don’t overcook. Drain, reserving 2 cups of broth for mixing later.
- Breaking the spaghetti into shorter pieces makes the casserole easier to eat and distribute.
Mix Ingredients:
In a large bowl, combine the pulled chicken pieces, cooked spaghetti, cream of mushroom soup, green pepper, onion, pimentos, seasoned salt, cayenne pepper, cheddar cheese (reserving 1 cup for topping), salt, and pepper.
- Stir in up to 2 cups of reserved chicken broth to create a creamy, cohesive mixture.

Assemble the Casserole:
Transfer the mixture to a greased 9×13-inch casserole pan. Sprinkle the remaining cheddar cheese over the top for a golden crust.
Bake:
Bake in a preheated oven at 350°F (175°C) for about 45 minutes, or until bubbly and the cheese topping begins to brown. If the top browns too quickly, cover loosely with foil.
Finish & Serve:
Remove from oven, let stand for a few minutes to firm up, slice, and serve warm. Optional: sprinkle cooked, chopped bacon or fresh herbs over the top for flavor enhancement.

Make-Ahead, Storage, and Freezing Tips

Freezing: Cover tightly and freeze casserole up to 6 months. Bake directly from frozen or thaw overnight in fridge before reheating.
Refrigeration: Keep assembled casserole (unbaked) in the refrigerator for up to 2 days. Bake when ready.
Leftovers: Refrigerate baked leftovers in airtight containers for up to 4 days. Reheat individual portions in the microwave or oven until hot.

Expert Tips for Perfect Chicken Spaghetti

Cook Chicken Gently: Simmering rather than boiling ensures tender, shreddable chicken and richer broth.
Al Dente Pasta: Slightly undercook pasta when boiling, as it will continue cooking in the oven.
Cheese Choices: Sharp cheddar is traditional, but you can mix in Monterey Jack or mozzarella for variety.
Spice It Up: Add extra cayenne for heat, or try a dash of hot sauce if you like things spicy.
Vegetable Add-Ins: Swap green bell pepper for red or use a mix. Add mushrooms or peas for more nutrition and flavor.
Customize Toppings: Chopped bacon, toasted breadcrumbs, or fresh herbs add delicious finishing touches.

Chicken Spaghetti Variations

Chicken spaghetti’s flexibility means you can tailor it to suit different tastes or dietary requirements:

Mushroom & Olive: Add sautéed mushrooms and sliced black olives for earthy flavor.
Southwest Style: Stir in chopped green chiles, taco seasoning, or corn for a southwestern kick.
Lighter Option: Use reduced-fat cheese and soups, substitute whole-wheat spaghetti, or add extra veggies.
Vegetarian: Swap chicken for sautéed mushrooms or cooked chickpeas, and use vegetable broth.

Serving Suggestions

Classic Side: Serve chicken spaghetti with a simple green salad tossed in vinaigrette.
Bread: Pair with garlic breadsticks or soft dinner rolls for dipping.
Vegetables: Offer steamed green beans or sautéed broccoli for a complete meal.
Potluck Perfect: Slice casserole into neat squares for serving at gatherings.

Frequently Asked Questions (FAQs)

Can I use rotisserie chicken or leftover chicken?

Yes, rotisserie chicken or leftover roast chicken can be substituted for poached chicken to save time. Just shred and measure 2 cups for the recipe.

Is it okay to use a different type of pasta?

Traditional chicken spaghetti uses thin spaghetti broken into pieces, but you can use angel hair, linguine, or even elbow macaroni for a similar effect.

How do I make chicken spaghetti without canned soup?

Prepare a homemade white sauce by combining butter, flour, and milk, then add sautéed mushrooms. This replaces the cream of mushroom soup and gives a fresh flavor.

Can I make it gluten-free?

Absolutely. Use gluten-free pasta and substitute a gluten-free thickener or soup for the casserole base.

Why do some recipes add bacon or breadcrumbs?

Bacon adds smoky crunch and depth, while toasted breadcrumbs enhance the texture of the cheesy topping, making for a more satisfying casserole.

How do you prevent casserole from drying out?

Don’t overbake. Use enough broth in the mixture and consider covering with foil for part of the bake. Layering cheese on the top also helps retain moisture.

Pro Tips for Chicken Spaghetti Success

For deeper flavor, caramelize the onions and sauté the peppers briefly before mixing into casserole.
Use freshly shredded cheese for better melt and taste compared to pre-shredded cheese.
If cooking in advance, add 2–4 additional tablespoons of broth or milk to keep spaghetti creamy when reheating.
Double the recipe and freeze one half in a foil pan for a stress-free future meal.
