Ingredients
- 1 pound boneless, skinless chicken breasts, cut into bite-sized pieces
- 2 tablespoons olive oil
- 2 tablespoons Cajun seasoning
- 1 teaspoon smoked paprika
- 1 pound spaghetti
- 4 tablespoons unsalted 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, to taste
- Freshly ground black pepper, to taste
- Red pepper flakes, optional
Instructions
- Step 1: Boil the spaghetti in a large pot of salted water according to package directions until al dente. Drain and set aside.
- Step 2: Combine the chicken pieces with Cajun seasoning and smoked paprika, tossing well to coat evenly.
- Step 3: Heat olive oil in a large skillet over medium-high heat. Add the seasoned chicken and cook, stirring occasionally, until browned and cooked through, about 6 to 8 minutes. Transfer chicken to a plate and set aside.
- Step 4: In the same skillet, melt butter over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
- Step 5: Sprinkle flour evenly into the skillet and whisk constantly for 1 to 2 minutes to create a smooth roux.
- Step 6: Gradually pour in the milk and chicken broth while whisking to prevent lumps. Bring the mixture to a gentle simmer, stirring often.
- Step 7: Add the cream cheese and 1 cup of shredded mozzarella. Stir until the cheeses melt completely and the sauce is smooth.
- Step 8: Add grated Parmesan cheese; season with salt, freshly ground black pepper, and red pepper flakes if using. Stir to combine.
- Step 9: Return the cooked chicken and any juices to the skillet. Simmer gently in the sauce for 2 to 3 minutes until heated through.
- Step 10: Add the drained spaghetti to the skillet. Toss thoroughly until the pasta is fully coated with the sauce.
- Step 11: Sprinkle the remaining 1 cup of mozzarella cheese over the pasta. Cover the skillet and let sit for 2 to 3 minutes, allowing the cheese to melt.
- Step 12: Serve hot, garnished with fresh parsley or extra Parmesan if desired.
Tips & Variations
- For a quicker option, use cooked rotisserie chicken instead of raw chicken breasts.
- Substitute any long pasta such as fettuccine or penne if you prefer.
- Adjust Cajun seasoning and red pepper flakes according to your desired spice level.
- Use low-fat milk and reduced-fat cheeses for a lighter version, though this may affect creaminess.
Storage
Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently over low heat on the stove or in the microwave, adding a splash of milk if the sauce thickens too much, to maintain its creamy texture.
