Ingredients

1 whole chicken (or a pre-cooked rotisserie chicken if you are short on time)
24 ounces of spaghetti noodles (which is roughly three-quarters of a large two-pound bag)
1 large onion, peeled and roughly chopped
2 stalks of celery, finely chopped
32-ounce block of Velveeta cheese, cut into small cubes for easier melting
1 can of Rotel tomatoes (diced tomatoes blended with green chilies)
1 can of cream of mushroom soup
1 to 2 teaspoons of Cajun seasoning, adjusted to fit your personal taste preferences
Optional: A touch of chicken bouillon (only needed if you choose to use a rotisserie chicken)
Optional: A splash of milk (for reheating any dry leftovers)
Optional: A drizzle of cooking oil for sautéing the vegetables

Step-by-Step Instructions

Step 1: Cook the Chicken and the Pasta

If you are starting with a whole raw chicken, submerge it in a large pot of water and bring it to a boil. Let the chicken cook thoroughly until the meat is incredibly tender and practically falling apart. Carefully remove the cooked chicken from the pot, but make sure to save that rich, bubbling chicken water. Add your spaghetti noodles directly to that flavorful broth and cook them according to the package directions.

If you are using a rotisserie chicken instead, simply add a touch of chicken bouillon to a large pot of water before boiling your pasta to replicate that rich, homemade flavor.

Step 2: Shred the Chicken Meat

While your pasta is boiling away, take your cooked chicken and carefully shred the meat into bite-sized pieces. Set the shredded meat aside in a bowl and make sure to discard all of the bones.

Step 3: Sauté the Aromatics

Once your spaghetti is perfectly tender, drain the noodles and return your large, empty pot to the stove over medium heat. Add a quick drizzle of oil to the bottom of the pot. Toss in your chopped onion and celery, cooking them and stirring often until the vegetables are beautifully softened and aromatic.

Step 4: Melt the Cheese Sauce

To your pot of softened vegetables, add the cubed Velveeta cheese, the entire can of Rotel tomatoes, and the can of cream of mushroom soup. Stir the mixture continuously. Keep stirring until every single cube of cheese is completely melted, resulting in a thick, bubbly, and smooth sauce.

Step 5: Combine and Season

Finally, add your cooked spaghetti noodles and the shredded chicken back into the pot with the hot cheese sauce. Toss everything together vigorously until the meat and pasta are evenly coated. Sprinkle in 1 to 2 teaspoons of Cajun seasoning to taste, give it one final stir, and serve it up hot.

Expert Cooking Tips

For the absolute best flavor profile, never throw away the water you used to boil the whole chicken; cooking the pasta in this homemade broth is the secret to the dish.
Cut your Velveeta block into uniform, bite-sized cubes before adding it to the pot so that it melts down quickly and evenly.
Make sure you keep your stovetop heat at a moderate medium when building the sauce; high heat can easily scorch the dairy at the bottom of the pot.
Do not drain the can of Rotel tomatoes before adding it in; those zesty juices help thin out the heavy Velveeta to create the perfect sauce consistency.
Taste the cheesy pasta before adding the full amount of Cajun seasoning, as the Rotel tomatoes already bring a slight kick of their own.

Variations to Try

Swap the traditional long spaghetti noodles for a shorter pasta like penne, rotini, or cavatappi, which feature ridges that perfectly trap the thick cheese sauce.
Stir in a cup of frozen peas, sweet corn, or diced bell peppers during the last few minutes of cooking to effortlessly sneak some extra vegetables into the meal.
If your family does not enjoy the flavor of mushrooms, you can easily substitute the cream of mushroom soup with a can of cream of chicken or cream of celery soup instead.

What to Serve With Chicken Spaghetti

A crisp, refreshing garden salad tossed with a light, tangy vinaigrette to cut through the heavy richness of the cheese sauce.
Warm, buttery garlic bread or toasted French bread slices for soaking up every last drop of the creamy sauce left on the plate.
Simple roasted green beans, steamed broccoli florets, or grilled asparagus for a vibrant and nutritious side dish.

Storage & Reheating

Refrigerator

Allow any leftover pasta to cool completely to room temperature before transferring it to an airtight container. Store it in the refrigerator, where it will stay fresh and delicious for up to 4 days.

Freezer

Because of the highly stabilized nature of processed Velveeta cheese, this dish actually freezes surprisingly well. Place the cooled pasta into a freezer-safe container or heavy-duty freezer bag, squeeze out any excess air, and freeze for up to 3 months. Let it thaw in the refrigerator overnight before attempting to warm it up.

Reheating

When reheating this dish, you might find that the leftovers appear a bit dry. To fix this, simply pour a little bit of milk into the pasta before reheating it in the microwave or on the stovetop. Stirring in that extra moisture will immediately bring the sauce back to its original creamy perfection.

Frequently Asked Questions

Can I bake this pasta in the oven instead?

Yes, if you prefer a baked casserole style, you can easily transfer the finished stovetop pasta into a greased 9×13-inch baking dish. Top it with a handful of shredded cheddar cheese and bake at 350°F for about 15 minutes, just until the top is bubbling and golden brown.

Is this dish extremely spicy?

The heat level of this meal is actually quite mild. The Rotel tomatoes provide a very gentle warmth, and you are in total control of the final spice level since you can adjust the amount of Cajun seasoning added at the very end of the cooking process.

Can I use leftover turkey instead of chicken?

Absolutely. Shredded leftover Thanksgiving turkey works incredibly well in this rich cheese sauce and is a fantastic way to repurpose holiday leftovers without feeling like you are eating the same meal twice.

Do I really have to use Velveeta cheese?

For this specific style of Southern comfort food, Velveeta is highly recommended. It provides a unique, melt-in-your-mouth creamy texture and a stabilized sauce that traditional shredded cheeses like cheddar simply cannot replicate without breaking or becoming grainy.

How many people does this recipe feed?

This recipe yields a truly massive amount of food. By utilizing 24 ounces of pasta and an entire whole chicken, you can easily feed between 8 to 10 hungry people, making it an incredibly affordable option for large gatherings.
