Step 1: Season the Chicken
In a bowl, toss the chicken with olive oil, Cajun seasoning, and smoked paprika until evenly coated. Set aside.

Step 2: Boil the Pasta
Bring a large pot of salted water to a boil. Cook the linguine until al dente, then drain and set aside. Save about ½ cup of the pasta water for later.

Step 3: Cook the Chicken
Heat a large skillet over medium-high heat. Add the chicken and cook for 6–8 minutes, until golden and cooked through. Remove and set aside.

Step 4: Start the Sauce
In the same skillet, melt butter over medium heat. Add garlic and cook for about 1 minute, then stir in the flour and cook for another 1–2 minutes to form a roux.

Step 5: Build the Sauce
Slowly whisk in the milk and chicken broth. Let it simmer, then stir in the cream cheese until melted. Add 1½ cups of mozzarella and all the Parmesan. Season with salt, pepper, and red pepper flakes to taste.

Step 6: Combine Everything
Add the pasta and chicken to the skillet. Toss until coated in the creamy sauce and everything is heated through.

Step 7: Optional Broil
For a cheesy top, transfer to a baking dish, sprinkle with remaining mozzarella, and broil for 2–3 minutes.

Step 8: Serve and Enjoy
Serve hot, garnished with parsley if you like. Creamy, cheesy, and packed with flavor!
