Cook the pasta according to package instructions until al dente. Drain and set aside.
Season the chicken breasts with salt and pepper on both sides.
In a large skillet, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant but not browned.
Add the seasoned chicken breasts to the skillet. Cook for 5-7 minutes on each side until golden brown and cooked through.
Remove the chicken from the skillet and let it rest for a few minutes before slicing it into strips.
In the same skillet, lower the heat and pour in the heavy cream. Stir well to combine, scraping up any bits from the bottom of the pan.
Stir in the grated Parmesan cheese, allowing it to melt and combine fully with the cream. Season with more salt and pepper if needed.
Add the cooked pasta to the skillet, tossing gently to coat the pasta in the creamy sauce.
Finally, add the sliced chicken on top of the pasta and garnish with chopped parsley before serving.
