Heat oil in a large Dutch oven over medium heat. Add the garlic and green onion and sauté until fragrant, about 2 minutes.

Stir in the pasta sauce and chicken broth. Bring to a boil over high heat. Once boiling, stir in the gnocchi and chicken. Cook, stirring occasionally, until gnocchi is tender, 6-8 minutes.

Stir in cream and Parmesan cheese and cook until heated through. Stir in red pepper flakes, and salt and pepper, to taste. Garnish with freshly chopped basil before serving, if desired.
