Ingredients

Scale

Chicken

  • 1 pound boneless, skinless chicken breasts, cut into bite-sized pieces
  • 2 tablespoons olive oil
  • 2 tablespoons Cajun seasoning
  • 1 teaspoon smoked paprika

Pasta

  • 1 pound spaghetti

Sauce

  • 4 tablespoons butter
  • 4 cloves garlic, minced
  • 1/4 cup all-purpose flour
  • 3 cups whole milk
  • 1 cup chicken broth
  • 8 ounces cream cheese, softened
  • 2 cups shredded mozzarella cheese, divided
  • 1/2 cup grated Parmesan cheese
  • Salt and freshly ground black pepper, to taste
  • Optional: Red pepper flakes for extra heat

Instructions

  1. Cook Spaghetti: Cook spaghetti according to package directions in salted water until al dente. Drain and set aside.
  2. Season Chicken: While pasta cooks, season chicken with Cajun seasoning and smoked paprika evenly to infuse flavor.
  3. Cook Chicken: Heat olive oil in a large skillet over medium-high heat. Add the seasoned chicken and cook until browned and cooked through, approximately 6–8 minutes. Remove chicken from skillet and set aside.
  4. Sauté Garlic: In the same skillet, melt butter over medium heat. Add minced garlic and sauté for 1 minute until fragrant to develop the base flavor.
  5. Make Roux: Sprinkle the flour into the butter and garlic and whisk continuously for 1–2 minutes to form a smooth roux which will thicken the sauce.
  6. Add Liquids: Gradually whisk in the whole milk and chicken broth, stirring constantly to avoid lumps. Bring the mixture to a gentle simmer to thicken.
  7. Melt Cheeses: Add the cream cheese and 1 cup of mozzarella cheese, stirring until both are melted and the sauce is smooth and creamy.
  8. Finish Sauce: Stir in Parmesan cheese and season with salt, freshly ground black pepper, and red pepper flakes if using, adjusting to taste.
  9. Combine Chicken and Sauce: Return cooked chicken to the skillet and simmer together for 2–3 minutes, allowing flavors to meld and chicken to heat through.
  10. Toss Pasta with Sauce: Add the cooked spaghetti to the skillet and toss everything together until the pasta is well coated with the creamy, cheesy sauce.

Notes

  • For a spicier dish, increase the amount of red pepper flakes or Cajun seasoning.
  • You can substitute whole milk with 2% or skim milk, but the sauce will be less rich.
  • Use freshly grated Parmesan cheese for the best flavor and melt.
  • This recipe can be made ahead and reheated gently on the stovetop with a splash of milk to restore creaminess.
  • To make it gluten free, use gluten-free spaghetti and substitute all-purpose flour with a gluten-free flour blend.
