Step‑by‑Step Instructions for Creamy Cajun Chicken Spaghetti with Garlic Mozzarella Sauce
Step 1: Season the Chicken
Begin by seasoning the boneless, skinless chicken breasts liberally with Cajun seasoning and smoked paprika. Allow the seasoned chicken to rest for about 10 minutes to let the spices penetrate deeply into the meat, enhancing the flavors. This resting time ensures a more flavorful and tender chicken for your Creamy Cajun Chicken Spaghetti.
Step 2: Cook the Spaghetti
In a large pot, bring salted water to a rolling boil and add the spaghetti. Cook according to package instructions until al dente, usually around 8-10 minutes. Once ready, drain the spaghetti in a colander, ensuring to reserve a bit of the pasta water for later use, which can help thicken your sauce.
Step 3: Cook the Chicken
In a large skillet over medium heat, add a drizzle of oil or a tablespoon of butter, then place the seasoned chicken in the pan. Sauté for approximately 6-8 minutes, flipping halfway, until the chicken is golden brown and cooked through (internal temperature should reach 165°F). Once done, remove the chicken and set it aside on a cutting board to rest.
Step 4: Prepare the Sauce
Using the same skillet, melt 2 tablespoons of butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant and golden. Next, sprinkle in 2 tablespoons of all-purpose flour, stirring continuously to create a roux. Cook for 1 minute until it bubbles and turns lightly golden, which will help thicken your creamy sauce.
Step 5: Create the Creamy Base
Gradually whisk in 1 cup of whole milk and 1 cup of chicken broth into the roux, bringing the mixture to a gentle simmer. Continue simmering for about 3-4 minutes, stirring frequently, until the sauce thickens to a velvety consistency. The creamy mixture should coat the back of a spoon when it is ready.
Step 6: Combine Cheese with Sauce
Stir in 4 oz of cream cheese until smooth and well incorporated into the sauce. After the cream cheese has melted and the sauce is creamy, fold in the drained spaghetti and the previously cooked Cajun chicken. Toss everything together gently to ensure the pasta is evenly coated in the rich garlic mozzarella sauce.
Step 7: Finalize the Dish
Transfer the creamy Cajun chicken spaghetti into an oven-safe dish, spreading it evenly. Top with remaining mozzarella cheese, creating a luscious layer of meltiness. Place the dish under the broiler set to high for about 2-3 minutes, keeping a close eye until the cheese is bubbly and golden brown, creating that perfect cheesy crust.

Expert Tips for Creamy Cajun Chicken Spaghetti
Let It Rest: Allow seasoned chicken to rest for 10 minutes before cooking. This enhances the flavor and ensures a tender bite in your Creamy Cajun Chicken Spaghetti.
Don’t Overcrowd: When cooking the chicken, avoid overcrowding the pan. This ensures even browning and the perfect sear to lock in flavor.
Taste as You Go: Always taste the sauce before serving. Adjust seasoning with salt and pepper to achieve your ideal flavor balance in the creamy sauce.
Watch the Broiler: Keep a close eye on the dish while broiling. It only takes a couple of minutes to reach that golden, bubbly perfection, and it can burn quickly!
Reserve Pasta Water: Save a bit of pasta water before draining. Adding it to your sauce can help adjust the consistency for a creamier texture.
Make Ahead Options
These Creamy Cajun Chicken Spaghetti with Garlic Mozzarella Sauce are perfect for meal prep enthusiasts! You can season and cook the chicken up to 24 hours in advance; simply refrigerate it in an airtight container to maintain its flavors and moisture. You can also prepare the sauce ahead of time and refrigerate it for up to 3 days. When you’re ready to serve, just reheat the sauce in a skillet, toss in the drained spaghetti and cooked chicken, and finish with a broil to melt the mozzarella until golden and bubbly. This way, you can enjoy a restaurant-quality meal with minimal fuss on busy weeknights!
