Sear the Chicken: Pat chicken dry; season with salt, pepper, garlic powder, and paprika. Heat olive oil in a large skillet over medium-high. Sear chicken 4–5 minutes per side until golden and cooked through (165°F). Transfer to a plate.
Make the Sauce: In the same skillet, melt butter. Add garlic and cook 30 seconds until fragrant. Stir in Italian seasoning and red pepper flakes.
Deglaze & Cream: Pour in chicken stock, scraping up the brown bits. Simmer 2–3 minutes. Stir in cream, Parmesan, lemon zest, and lemon juice; whisk until smooth and slightly thickened.
Finish: Return chicken (and juices) to the skillet. Simmer 5-10 minutes to absorb the flavor and coat with sauce and to make sure chicken is entirely cooked.
Serve: Top with fresh basil and extra Parmesan. Serve warm with your favorite side. I usually serve with masked potatoes and bread and dip up the extra sauce. Also pairs well with my Steakhouse Caesar Recipe.
