Step‑by‑Step Instructions for Creamy Cajun Chicken Spaghetti
Step 1: Prep Chicken
Begin by cutting your boneless, skinless chicken breasts into bite-sized pieces, ensuring even cooking during the process. Generously coat the chicken with Cajun seasoning and smoked paprika, letting it marinate for about 10 minutes. This allows the spices to penetrate the meat, enhancing the flavor profile of the Creamy Cajun Chicken Spaghetti.
Step 2: Cook Spaghetti
In a large pot, bring salted water to a rolling boil and add your spaghetti. Cook until al dente, typically around 8-10 minutes, stirring occasionally to prevent sticking. Once cooked, drain the pasta in a colander and set it aside. This step ensures that the spaghetti will pair perfectly with the creamy sauce later on.
Step 3: Sear Chicken
Heat a large skillet over medium-high heat and add a drizzle of oil or a tablespoon of butter. Carefully add the marinated chicken pieces to the skillet, making sure not to overcrowd the pan. Sear the chicken for 6-8 minutes until it’s nicely browned and cooked through, reaching an internal temperature of 165°F. Remove from the skillet and set aside.
Step 4: Make Roux
In the same skillet, melt 2 tablespoons of butter over medium heat, allowing it to bubble but not brown. Add minced garlic, sautéing for 30 seconds until fragrant. Whisk in 2 tablespoons of all-purpose flour, stirring continuously for another minute to create a roux. This will serve as the base for your sauce, thickening it beautifully.
Step 5: Prepare Sauce
Gradually pour in 1 cup of whole milk and 1 cup of chicken broth while whisking constantly to avoid lumps. Continue to cook for about 3-5 minutes until the sauce begins to thicken. Once thickened, stir in 4 ounces of cream cheese, ensuring it’s fully incorporated and the sauce is creamy. The sauce is the heart of your Creamy Cajun Chicken Spaghetti.
Step 6: Combine Ingredients
Add the seared chicken back into the skillet, along with 1-2 cups of cooked spaghetti. Gently toss everything together until the pasta is thoroughly coated in the creamy sauce. Allow it to simmer for an additional 2-3 minutes over low heat to meld the flavors, creating a harmonious blend of tastes in your Creamy Cajun Chicken Spaghetti.
Step 7: Broil
Transfer the combined mixture into an oven-safe dish for the final touch. Top it generously with shredded mozzarella cheese and place it under the broiler on high for about 2-3 minutes. Keep a close eye on it, removing it once the cheese is bubbling and golden brown, creating a delightful finish to your Creamy Cajun Chicken Spaghetti.

Make Ahead Options
These Creamy Cajun Chicken Spaghetti with Garlic Mozzarella Sauce ingredients are perfect for meal prepping! You can season and marinate the chicken up to 24 hours in advance by coating it with Cajun seasoning and smoked paprika, which helps lock in delicious flavors. Additionally, you can cook the spaghetti up to 3 days in advance; just refrigerate it in an airtight container. When you’re ready to serve, simply prepare the creamy sauce and combine everything in the skillet, heating gently until warmed through. This ensures your dish remains just as tasty and satisfying while saving you precious time on busy weeknights!
