Cook the pasta according to package directions and reserve ½ cup of pasta water.
Heat olive oil in a large skillet over medium heat. Add chicken, Italian seasoning, salt, and pepper. Cook until the chicken is fully cooked.
Add garlic and cherry tomatoes. Cook 5-7 minutes, stirring occasionally, until the tomatoes burst and create a sauce.
Stir in chicken broth and light cream cheese until smooth.
Add the cooked pasta and Parmesan cheese. Toss everything together, adding a little reserved pasta water if needed.
Top with fresh basil and serve.
