Ingredients

For the Cajun Chicken:

2 boneless, skinless chicken breasts, sliced into strips
2 teaspoons Cajun seasoning
1 tablespoon olive oil
½ teaspoon smoked paprika
¼ teaspoon black pepper

For the Pasta:

12 ounces spaghetti
Salt for pasta water

For the Garlic Mozzarella Sauce:

2 tablespoons unsalted butter
5 cloves garlic, minced
1 cup heavy cream
¾ cup chicken broth
1½ cups shredded mozzarella cheese
¼ cup grated Parmesan cheese
½ teaspoon Italian seasoning
Salt, to taste

For Garnish (Optional):

Fresh parsley, chopped
Extra shredded mozzarella

Instructions

Bring a large pot of salted water to a boil. Cook spaghetti according to package instructions until al dente. Reserve ½ cup of pasta water, then drain and set aside.
While the pasta cooks, season chicken strips with Cajun seasoning, smoked paprika, and black pepper, coating evenly.
Heat olive oil in a large skillet over medium-high heat. Add the seasoned chicken and cook for 5–7 minutes until fully cooked and lightly browned. Remove chicken from skillet and set aside.
In the same skillet, reduce heat to medium and melt butter. Add minced garlic and sauté for 30–45 seconds until fragrant but not browned.
Pour in heavy cream and chicken broth, stirring to combine. Bring to a gentle simmer.
Reduce heat to low and slowly stir in shredded mozzarella and Parmesan cheese, allowing them to melt smoothly into the sauce.
Season with Italian seasoning and salt to taste. Stir until sauce is thick, creamy, and glossy.
Add cooked spaghetti to the sauce, tossing gently to coat. If needed, add reserved pasta water a little at a time to loosen the sauce.
Return the cooked chicken to the skillet and toss everything together until evenly combined and heated through.
Remove from heat, garnish with fresh parsley and extra mozzarella if desired, and serve immediately.

Tips for the Best Cajun Chicken Spaghetti

For the creamiest sauce, shred your mozzarella from a block instead of using pre-shredded cheese. Freshly shredded cheese melts more smoothly and avoids a grainy texture. Keep the heat low when adding cheese to prevent separation.

If you prefer a spicier dish, add a pinch of cayenne pepper or red pepper flakes to the sauce. For a milder version, reduce the Cajun seasoning slightly and add more cream.

Variations and Customizations

This recipe is incredibly flexible. Swap chicken for shrimp to create a Cajun shrimp spaghetti variation. Use gluten-free pasta if needed, or substitute half-and-half for heavy cream for a lighter sauce.

You can also add vegetables such as sautéed bell peppers, mushrooms, or spinach to boost nutrition and color. Smoked gouda or Monterey Jack can be mixed with mozzarella for a more complex cheese profile.

Serving Suggestions

Serve Creamy Cajun Chicken Spaghetti with Garlic Mozzarella Sauce with a crisp green salad and warm garlic bread for a complete meal. A simple side of roasted broccoli or asparagus pairs beautifully with the richness of the pasta.

This dish also reheats well, making it a great option for meal prep or next-day leftovers.
