Cook the Chicken:
Season chicken with salt, pepper, paprika, and Italian seasoning.
In a large skillet, melt 2 tbsp butter over medium heat. Add chicken and cook for 4–5 minutes, stirring occasionally, until golden and cooked through.
Add Lemon & Garlic:
Stir in minced garlic, lemon zest, and lemon juice. Cook for 1–2 minutes to blend flavors. Remove chicken from skillet and set aside.
Prepare the Linguine:
Cook linguine in salted boiling water until al dente (per package instructions). Reserve ¼ cup pasta water, then drain.
Make the Parmesan Sauce:
In the same skillet, melt remaining 2 tbsp butter over medium heat. Add heavy cream and garlic powder, stirring until smooth.
Gradually whisk in Parmesan cheese until the sauce is creamy and thick. Season with salt and pepper.
Combine & Serve:
Toss cooked linguine in the sauce, adding reserved pasta water if needed to loosen it.
Top with lemon garlic chicken, extra Parmesan, and a sprinkle of fresh parsley.
