Season and Dredge Chicken:
Season chicken with salt, pepper, and Italian seasoning. Lightly dredge in flour to coat.
Sear the Chicken:
In a large skillet, heat olive oil and 1 tablespoon butter over medium-high heat. Add chicken and cook 3–4 minutes per side until golden and cooked through. Remove and set aside.
Make the Scampi Sauce:
In the same skillet, reduce heat to medium. Add remaining butter and garlic. Sauté for 30 seconds until fragrant.
Deglaze:
Pour in white wine and scrape up any browned bits. Simmer for 2–3 minutes to reduce slightly. Stir in lemon juice and zest.
Toss Pasta and Finish:
Add cooked pasta to the skillet and toss in the sauce. Return chicken to the pan and toss gently to coat everything in the lemon-garlic butter.
Serve:
Sprinkle with parsley, optional red pepper flakes, and parmesan. Serve immediately with crusty bread or a green salad.
