Ingredients for Your Perfect Chicken Spaghetti

To make this creamy chicken spaghetti really shine, use quality ingredients and keep them simple:

  • 2 pounds boneless skinless chicken breasts
  • 1 (16-ounce) package spaghetti
  • 1 (10-ounce) can Ro*Tel Tomatoes
  • 2 (10.5-ounce) cans cream of mushroom soup
  • 1 (16-ounce) package Velveeta cheese
  • 4 ounces cream cheese
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 cup shredded sharp cheddar cheese

How to Make the Best Chicken Spaghetti (Step-by-Step Instructions)

  1. Cook the chicken: Place the chicken in a large pot and just cover with water. Cook over medium-low heat until cooked through. Try not to boil the chicken as it can make it tough. Allow to cool enough to handle, then shred using two forks.
  2. Prepare the baking dish: Preheat the oven to 350°F. Lightly grease a 13×9-inch baking dish with nonstick cooking spray.
  3. Cook the spaghetti: Cook the pasta to al dente according to the package directions. Drain and set aside.
  4. Make the sauce and combine: In a large pot, combine the Ro*Tel with the juice, undiluted cream of mushroom soup, Velveeta cheese, and cream cheese. Heat over low heat, stirring constantly, until the cheeses have melted. Add the garlic powder and onion powder. Add the shredded chicken and cooked spaghetti. Mix well. Pour the mixture into the prepared dish and sprinkle with the shredded cheddar cheese.
  5. Bake: Bake for 20 to 30 minutes or until heated through and the cheese has melted.

Expert Tips for Foolproof Chicken Spaghetti

  • Achieving Al Dente Pasta: Pasta cooked al dente holds up better when baked, preventing mushiness. Test pasta a minute before package time to ensure it’s still firm.
  • Perfect Creamy Texture: Stir sauce constantly over low heat to melt cheeses evenly. Avoid overheating or thinning with extra liquid, which can cause separation.
  • Shredding Chicken Like a Pro: Use two forks or toss cooked breasts into a stand mixer with paddle attachment for quick shredding.
  • Seasoning to Taste: Taste the sauce before baking and adjust garlic, onion powder, or add salt if needed to enhance flavors.

Make it Your Own: Customizing Your Chicken Spaghetti

Feel free to personalize this recipe by adding diced green chilies for extra spice or sautéed onions and bell peppers for texture. A dash of hot sauce stirred into the sauce adds a pleasant kick. Experiment with different cheese blends like a smoky Gouda or sharp Monterey Jack. Just fold these additions into the sauce before mixing with pasta to maintain the creamy consistency.

Preparing Your Chicken for Success

  • Poaching Chicken: Place chicken breasts in a single layer in a pot. Cover with cold water, bring to a gentle simmer over medium-low heat. Cook until internal temperature reaches 165°F. Avoid boiling to keep chicken tender.
  • Using Rotisserie Chicken: Remove skin and shred meat, removing excess fat. It’s a great shortcut saving cooking time while preserving flavor.
  • Efficient Shredding: Use two forks pulling meat apart, or place warm chicken breasts in a stand mixer on low speed for 30 seconds until shredded evenly.

Meal Prep, Freezing & Reheating Your Chicken Spaghetti

  • Meal Prep Tips: Portion individual servings into airtight containers. Store in the fridge up to 4 days for quick lunches or dinners.
  • Freezing Instructions: Freeze the casserole either baked or unbaked. Wrap tightly with plastic wrap and foil, freeze up to 3 months. Thaw overnight in fridge before reheating.
  • Reheating Best Practices: Warm single portions in the microwave with a damp paper towel to prevent drying. For the whole casserole, reheat covered at 350°F until warmed through, about 20 minutes.

What to Serve with Chicken Spaghetti

Complete your meal with any of these crowd-pleasing sides:

  • Crisp green salad with vinaigrette
  • Garlic bread or crusty French bread
  • Steamed green beans
  • Roasted broccoli florets

Essential Equipment for Making Chicken Spaghetti

To make this recipe smoother, I recommend:

  • A good 13×9-inch baking dish for even cooking

  • Shredding forks or a stand mixer for effortless chicken shredding

Having these tools ready will make your experience more enjoyable and efficient.

Yes! You can prepare the casserole a day ahead and refrigerate before baking. This is perfect for meal prepping or busy nights.

How do I prevent my chicken spaghetti from being dry/soggy/bland?

Cook pasta al dente to avoid mushiness, shred chicken finely, and ensure cheese melts gently for creamy sauce. Taste and adjust seasoning before baking.

What’s the best way to scale this recipe up or down?

Simply multiply or reduce the ingredients proportionally. Use larger or smaller baking dishes accordingly.
