The Ultimate Comfort Food: A Deep Dive into This Creamy Chicken Spaghetti Masterpiece

This creamy chicken spaghetti is the ultimate comfort food! Tender chicken, thin spaghetti, and a luscious three-cheese sauce—cream cheese, cheddar, and mozzarella—come together with diced tomatoes and green chilies for a rich, flavorful dish that’s perfect for weeknight dinners or casual gatherings.

Ingredients

Scale
  • 2 small boneless skinless chicken breasts

  • 2 teaspoons Italian seasoning

  • Salt & pepper, to taste

  • 2 tablespoons olive oil

  • 4 tablespoons butter

  • 1 small yellow onion, diced

  • 3 cloves garlic, minced

  • 4 tablespoons all-purpose flour

  • 1½ cups chicken broth

  • ¾ cup milk

  • 4 oz cream cheese, softened

  • 1 cup cheddar cheese, shredded

  • 10 oz diced tomatoes with green chilies (Rotel)

  • 8 oz thin spaghetti

  • 1 cup mozzarella cheese, shredded

  • Red pepper flakes & chopped parsley, for garnish

Instructions

  1. Preheat oven: Set to 400°F.

  2. Cook chicken (optional):

    • Slice chicken in half lengthwise. Pat dry and season with salt, pepper, and Italian seasoning.

    • Heat olive oil over medium-high heat and sear chicken 5–6 minutes per side. Remove, let cool slightly, and dice into bite-sized pieces.

  3. Make the sauce:

    • Reduce heat to medium-low in the same pot. Melt butter and scrape up any browned bits (“fond”) from the bottom.

    • Add onion and cook 4 minutes until softened. Add garlic and cook 1 minute.

    • Sprinkle flour over the onions, toss to coat, and cook 2 minutes to remove raw flour taste.

    • Gradually add chicken broth, whisking to maintain thickness. Add milk slowly, whisking until smooth.

    • Stir in cream cheese until melted and smooth. Reduce heat to low and add shredded cheddar, mixing well.

  4. Combine ingredients:

    • If desired, thin sauce with a little tomato juice. Otherwise, drain juice and add diced tomatoes and cooked chicken.

    • Stir in cooked spaghetti. Transfer to a lightly greased 9×13-inch casserole dish if your pot isn’t oven-safe.

  5. Bake:

    • Top with mozzarella cheese. Bake uncovered for 15 minutes.

    • Optional: Broil 1–2 minutes at 475°F to lightly brown the top—watch carefully.

  6. Serve: Garnish with red pepper flakes and parsley. Pair with garlic bread for a complete meal.

Notes

  • Cheese tip: Use room-temperature cream cheese for easier melting.

  • Chicken shortcut: Use pre-cooked rotisserie chicken for a faster version.

  • Spicy variation: Add extra diced green chilies or red pepper flakes for more heat.

  • Make-ahead: Assemble in a casserole dish and refrigerate up to 24 hours before baking.
