Boil a salted pot of water and cook pasta according to package directions.

When the pasta water is about to boil, add olive oil to a skillet over medium heat. Add the onion and sauté for 8-10 minutes, or until it's softened and lightly browned.

Add the garlic to the pan and cook for 30 seconds, until fragrant.

Add the cream cheese, lemon juice and zest, and Italian seasoning. Stir for a couple of minutes until the cheese has melted into a sauce. Stir in the parmesan.

Reserve ½ cup of the pasta water prior to draining the pasta. Add ¼ cup of the pasta water to the sauce. If you want the sauce thinned even more, add pasta water one tablespoon at a time.

Once the sauce is thinned to your liking, add in the basil, parsley, and salt & pepper. Add the pasta to the skillet and toss. Serve immediately.
