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 pasta: Cook spaghetti according to package directions in salted boiling water until al dente. Drain and set aside.
  2. Season chicken: While pasta cooks, season the bite-sized chicken pieces evenly with Cajun seasoning and smoked paprika.
  3. Cook chicken: Heat olive oil in a large skillet over medium-high heat. Add the chicken and cook, stirring occasionally, until browned and cooked through, about 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 about 1 minute until fragrant but not browned.
  5. Make roux: Sprinkle flour into the butter and garlic, whisking continuously for 1–2 minutes to form a smooth roux and remove the raw flour taste.
  6. Add liquids: Gradually whisk in the whole milk and chicken broth, stirring constantly to prevent lumps from forming. Bring the mixture to a gentle simmer, allowing it to thicken slightly.
  7. Add cheeses: Stir in the softened cream cheese and 1 cup of shredded mozzarella cheese until melted and smooth.
  8. Season sauce: Stir in grated Parmesan cheese, then season with salt, freshly ground black pepper, and red pepper flakes if using, adjusting to your taste.
  9. Reintroduce chicken: Return the cooked chicken to the skillet, stirring it into the sauce. Let everything simmer together for 2–3 minutes to heat through and meld flavors.
  10. Combine pasta: Add the cooked spaghetti to the skillet and toss well to thoroughly coat the pasta in the creamy Cajun sauce.
  11. Melt topping cheese: Sprinkle the remaining 1 cup of shredded mozzarella cheese evenly on top of the pasta. Cover the skillet and let it sit for 2–3 minutes off heat until the cheese melts.
  12. Serve: Serve the creamy Cajun chicken spaghetti hot, optionally garnished with fresh parsley or extra Parmesan cheese for added brightness and flavor.

Notes

  • You can adjust the amount of Cajun seasoning and red pepper flakes to control the heat level.
  • For a lighter version, substitute whole milk with 2% or skim milk, though the sauce will be less rich.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently on the stovetop.
  • To make it gluten-free, use gluten-free flour and pasta alternatives.
  • Adding vegetables like bell peppers or spinach can add color and nutrients to the dish.
