01 - Bring a large pot of salted water to a boil. Cook the fettuccine following package directions until al dente. Drain, reserving ½ cup pasta water.
02 - While pasta cooks, heat olive oil in a large skillet over medium-high heat. Season chicken strips with salt and pepper. Sear for 4–5 minutes per side until golden and cooked through. Remove and set aside.
03 - In the same skillet, reduce heat to medium. Melt butter and sauté minced garlic for 1 minute until fragrant.
04 - Pour in heavy cream, stirring continuously. Allow to simmer gently for 3–4 minutes.
05 - Whisk in Parmesan cheese and nutmeg if using. Stir until the sauce is smooth and thickened. Season with salt and pepper to taste.
06 - Return chicken to the skillet. Add drained pasta, tossing to coat evenly. Gradually add reserved pasta water to loosen the sauce as needed.
07 - Plate immediately, garnished with chopped parsley and extra Parmesan cheese.
