How to Make Ultimate Chicken Spaghetti

Step 1: Prepare the Chicken

Place chicken breasts in a large pot and just cover with water. Cook over medium-low heat until thoroughly cooked but not boiling (boiling can toughen the meat). Once cool enough to handle, shred the chicken using two forks.

Step 2: Prep the Pasta and Oven

Preheat your oven to 350°F and lightly grease a 13×9-inch baking dish with nonstick cooking spray. Cook the spaghetti until al dente according to package directions, then drain and set aside.

Step 3: Create the Cheese Sauce

In a large pot, combine the Ro*Tel tomatoes (with juice), undiluted cream of mushroom soup, Velveeta cheese, and cream cheese. Heat over low, stirring constantly until all cheeses have completely melted. Add garlic powder and onion powder for flavor.

Step 4: Combine and Assemble

Add the shredded chicken and cooked spaghetti to the cheese sauce mixture. Mix thoroughly until everything is well coated. Transfer this creamy mixture to your prepared baking dish and top with shredded sharp cheddar cheese.

Step 5: Bake to Perfection

Bake for 20-30 minutes until the casserole is heated through and the cheese topping has melted to a beautiful golden finish.

Pro Tips for Making the Recipe

  • Don’t Overcook the Pasta: Cook it slightly less than al dente since it will continue cooking in the oven.
  • Grate Your Own Cheese: Pre-shredded cheese has anti-caking agents that can prevent proper melting. Freshly grated cheese melts much better.
  • Low and Slow Cheese Melting: Keep the heat low when melting the cheeses to prevent scorching and ensure a smooth sauce.
  • Season to Taste: Don’t be afraid to adjust the seasonings before baking. This recipe is very forgiving!
  • Even Distribution: Make sure the chicken and pasta are evenly distributed throughout the mixture for the best dining experience.

How to Serve

This Ultimate Chicken Spaghetti is a versatile dish that pairs wonderfully with several sides:

Simple Sides:

Serve with a crisp green salad dressed with a light vinaigrette to balance the richness of the casserole.

Veggie Companions:

Steamed broccoli or roasted vegetables make excellent nutritious sides that complement the creamy pasta perfectly.

Bread Options:

Garlic bread or a crusty French baguette is perfect for sopping up every last bit of the delicious sauce.

Make Ahead and Storage

Storing Leftovers

Store leftover chicken spaghetti in an airtight container in the refrigerator for up to 3-4 days. The flavors actually improve overnight, making for delicious next-day lunches.

Freezing

This dish freezes beautifully! Prepare the casserole up to the baking step, then wrap tightly with plastic wrap and aluminum foil. Freeze for up to 3 months.

Note: Always allow the dish to cool completely before freezing to prevent ice crystals from forming.

Reheating

For refrigerated leftovers, reheat individual portions in the microwave for 2-3 minutes, or place the entire casserole (if there’s enough left) in a 350°F oven for about 20 minutes until heated through.

For frozen casserole, thaw overnight in the refrigerator, then let it sit at room temperature for about 30 minutes before baking. Bake at the original temperature until hot and bubbly, approximately 30-40 minutes.

FAQs

  1. Can I use different pasta shapes for this recipe?

    Absolutely! While traditional spaghetti works wonderfully, feel free to substitute with penne, rotini, or even farfalle. Just remember to cook the pasta slightly less than al dente since it will continue cooking in the oven.

  2. What can I substitute for Velveeta if I don’t have it on hand?

    If you don’t have Velveeta, you can substitute with 2 cups of American cheese or a combination of monterey jack and cheddar cheese. Add 1-2 tablespoons of milk or cream to help create that smooth, creamy texture Velveeta provides.

  3. Can I make this recipe with leftover rotisserie chicken?

    Definitely! Using rotisserie chicken is a fantastic time-saver. Simply shred about 3-4 cups of rotisserie chicken and proceed with the recipe as directed. The additional flavor from the rotisserie seasoning will add another delicious dimension to the dish.

  4. How can I make this recipe lighter or healthier?

    For a lighter version, try using reduced-fat cream cheese, light Velveeta, whole wheat pasta, and reduced-fat cheddar. You can also increase the veggie content by adding diced bell peppers, spinach, or broccoli to the mix. The dish will still be creamy and satisfying with fewer calories.

Final Thoughts

This Ultimate Chicken Spaghetti is more than just a meal – it’s a hug in casserole form! Perfect for family dinners, potlucks, or whenever you need some good old-fashioned comfort food, this dish delivers big on flavor while keeping preparation simple. The creamy cheese sauce, tender chicken, and perfectly cooked pasta create an irresistible combination that will have everyone coming back for seconds.
