Boil a pot of water for the pasta and cook it al dente according to package directions. Before draining, reserve 1 cup of the hot pasta water.
Meanwhile, cut the cream cheese into smaller pieces and microwave it until very soft (try 20-30 second intervals). Prep all ingredients so they're ready to go as soon as the pasta is cooked.
Return the drained pasta to the pot it was cooked in, and quickly add the cream cheese and butter. Cover the pot and let it sit for about a minute (this helps it soften up more).
Uncover the pot and add in the garlic powder, onion powder, red pepper flakes, Italian seasoning, and parsley.
Add about ¼ cup of the hot pasta water to the pot, and start tossing it, gradually adding more of the water until the cheese has melted into a creamy sauce. You may not use up the entire cup of water.
Season with salt & pepper to taste and serve. This pasta is best enjoyed right away.
