Step 1 – Cook the Chicken:

Season chicken with salt, pepper, and Italian seasoning. Heat olive oil in a large skillet over medium-high heat. Add chicken and cook for 6–8 minutes until golden brown and fully cooked. Remove from skillet and set aside.

Step 2 – Make the Garlic Butter Sauce:

In the same skillet, reduce heat to medium. Melt the butter and stir in minced garlic. Sauté for 1 minute until fragrant.

Step 3 – Build the Alfredo Sauce:

Sprinkle in the flour, whisking continuously for 1 minute to create a roux. Slowly pour in the heavy cream while whisking to avoid lumps. Bring to a gentle simmer and cook for 3–4 minutes until slightly thickened.

Step 4 – Add Cheese & Flavor:

Stir in Parmesan, mozzarella, and garlic powder (optional). Continue stirring until the cheese melts, and the sauce becomes creamy and smooth.

Step 5 – Cook the Pasta:

While the sauce simmers, bring a large pot of salted water to a boil. Cook linguine according to package directions until al dente. Drain and set aside.

Step 6 – Combine & Serve:

Add cooked chicken and linguine to the Alfredo sauce. Gently toss to coat everything in the rich, cheesy sauce. Let simmer for 2 more minutes to blend flavors.

Step 7 – Garnish & Enjoy:

Top with freshly chopped parsley for a pop of color and freshness. Serve hot.
