Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions for al dente. Drain (do not rinse.)
8 ounces dry pasta
Meanwhile, season chicken cutlets with salt, pepper and 1 teaspoon Italian seasoning. Heat the olive oil in a large skillet over medium heat. Add the chicken and cook for 4-7 minutes per side, until cooked through. (The center should read 165° F on an instant read thermometer.) Transfer chicken cutlets to a clean plate and cover with foil to keep warm. (Optional: wash out the skillet.)
1 tablespoon olive oil, 4 boneless skinless chicken breast cutlets*, salt and pepper, 1 teaspoon Italian seasoning
Add the butter to the pan and cook until melted. Add the minced garlic and flour and cook for 30 seconds, stirring. Stir in the milk, remaining ½ teaspoon Italian seasoning, ½ teaspoon salt, ¼ teaspoon garlic powder and a bit of black pepper.
2 tablespoons unsalted butter, 3 cloves garlic, 2 tablespoons all-purpose flour, 1 ½ cups whole milk, ½ teaspoon Italian seasoning, ½ teaspoon salt, ¼ teaspoon garlic powder, black pepper
Bring to a gentle simmer. Simmer for 2-3 minutes, stirring often, until slightly thickened. Do not let the sauce boil.
Remove pan from the heat and stir in the grated Parmesan, a little at a time, until it melts into the sauce. Then stir in the cooked pasta. Taste and add more salt and pepper if needed.
¾ cup freshly grated Parmesan cheese
Slice chicken into ½-inch thick slices. Serve chicken over pasta, with a sprinkle of fresh parsley if desired.
