Cook pasta according to package directions. Drain and set aside.
While pasta is cooking, heat olive oil in a large skillet over medium-high heat. Add chicken and cook until browned and cooked through. Remove chicken from skillet and set aside.
In the same skillet, melt butter over medium heat. Add minced garlic and cook until fragrant, about 1 minute.
Pour in chicken broth and heavy cream. Bring to a simmer and cook for 5 minutes, stirring occasionally, until the sauce thickens.
Stir in grated Parmesan cheese, salt, and pepper. Cook until cheese is melted and sauce is smooth.
Return the cooked chicken to the skillet. Add the cooked pasta and toss to coat evenly with the sauce.
Serve hot, garnished with extra Parmesan cheese if desired.
Notes
This creamy chicken pasta is delicious served with a side salad and crusty bread.
