Here’s what you’ll need to make this creamy Cajun chicken spaghetti:

For the Cajun Chicken:

1 pound boneless, skinless chicken breasts, cut into bite-sized pieces
2 tablespoons olive oil
2 tablespoons Cajun seasoning
1 teaspoon smoked paprika

For the Garlic Mozzarella Sauce:

1 pound spaghetti
4 tablespoons butter
4 cloves garlic, minced
¼ cup all-purpose flour
3 cups whole milk
1 cup chicken broth
8 ounces cream cheese, softened
2 cups shredded mozzarella cheese, divided
½ cup grated Parmesan cheese
Salt and freshly ground black pepper, to taste
Optional: Red pepper flakes for extra heat

Let’s Get Started

Now that you have all your ingredients, let’s dive into the steps for making this creamy Cajun chicken spaghetti with garlic mozzarella sauce.

Step 1: Prepare the Chicken

Season the Chicken: In a bowl, toss the chicken pieces with Cajun seasoning, smoked paprika, salt, and pepper until evenly coated.
Cook the Chicken: Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the seasoned chicken and cook for 5–7 minutes, or until the chicken is cooked through and no longer pink. Remove the chicken from the skillet and set it aside.

Step 2: Cook the Spaghetti

Cook the Pasta: In a large pot of salted boiling water, cook the spaghetti according to the package instructions, until al dente. Drain the pasta, reserving 1 cup of pasta water, and set it aside.

Step 3: Make the Creamy Garlic Mozzarella Sauce

Sauté the Garlic: In the same skillet used for the chicken, melt 4 tablespoons of butter over medium heat. Add the minced garlic and sauté for 1–2 minutes until fragrant.
Make the Roux: Stir in the flour and cook for 1 minute to form a roux. This will help thicken the sauce.
Add Liquids: Gradually whisk in the whole milk and chicken broth. Continue whisking until the mixture is smooth and thickened, about 3–5 minutes.
Add Cream Cheese and Cheese: Stir in the softened cream cheese until smooth, then add 1½ cups of shredded mozzarella cheese and the grated Parmesan cheese. Stir until the cheese melts into the sauce and the mixture becomes creamy and smooth.
Season the Sauce: Taste the sauce and add salt and pepper as needed. If you like it spicier, add red pepper flakes to taste.

Step 4: Combine Everything

Add the Chicken and Pasta: Return the cooked chicken to the skillet with the sauce, and then add the drained spaghetti. Toss everything together to coat the pasta and chicken in the creamy sauce. If the sauce is too thick, add a bit of the reserved pasta water to reach your desired consistency.
Finish with Cheese: Sprinkle the remaining mozzarella cheese over the top and let it melt into the pasta for an extra cheesy finish.

Step 5: Serve and Enjoy

Serve: Plate the creamy Cajun chicken spaghetti and garnish with extra red pepper flakes or fresh parsley if desired. Serve immediately, and enjoy the rich, creamy, and flavorful dish!

Servings and Pairing

This recipe yields about 4–6 servings, depending on portion sizes.

Pairing Ideas:

Side Salad: A crisp side salad with a tangy vinaigrette balances out the richness of the pasta.
Garlic Bread: Serve with warm garlic bread or crusty baguette to soak up all the creamy sauce.
Grilled Vegetables: Roasted or grilled vegetables like zucchini, bell peppers, or asparagus add a healthy, colorful side to the meal.
Wine: Pair with a glass of Chardonnay or Sauvignon Blanc for a refreshing contrast to the creamy dish.

Variations

If you want to customize this dish, here are a few variations to try:

Add Shrimp: Toss in some sautéed shrimp along with the chicken for a seafood twist.
Vegetarian Version: Skip the chicken and use mushrooms, bell peppers, or zucchini for a delicious vegetarian option.
Use Different Cheese: Swap the mozzarella for Gouda or provolone for a different cheesy flavor.
Make it Spicy: Add more Cajun seasoning or a splash of hot sauce for extra heat.

Storage Tips

Leftovers? Here’s how to store and reheat this dish:

Refrigeration: Store any leftovers in an airtight container in the refrigerator for up to 3 days.
Reheating: Reheat on the stovetop over low heat, adding a splash of milk or broth to loosen the sauce. You can also reheat in the microwave, stirring occasionally.
Freezing: This dish can be frozen for up to 1 month. Store it in an airtight container and reheat slowly when ready to serve.

FAQs

Can I use another type of pasta?

Yes! While spaghetti works great, you can also use fettuccine, penne, or linguine for this recipe.

Can I make it ahead of time?

You can prep the chicken and make the sauce ahead of time, but for best results, combine everything just before serving. The pasta can be cooked and stored separately as well.

What if I don’t have Cajun seasoning?

You can make your own Cajun seasoning by combining paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, and black pepper. Adjust the heat level to your preference.

Is this recipe spicy?

The level of spiciness depends on how much Cajun seasoning you use. For a milder version, reduce the Cajun seasoning or omit the red pepper flakes.
