Cook pasta according to package directions.
While pasta is boiling, cook garlic in butter in a saucepan over medium heat until fragrant, about 30 seconds. Add dried basil and onion powder. Whisk in cream cheese until melted and smooth.
Add chicken broth a little bit at a time and simmer 3-4 minutes or until slightly thickened.
Remove from heat and stir in parmesan cheese. Season with salt & pepper to taste and serve over pasta.
