Cook pasta or noodles according to packaging. Reserve ¼ cup of pasta water and drain the rest.
In a pan, add your butter and minced garlic. Stir to coat the garlic in the butter as it melts. Saute for a few minutes until garlic softens and becomes fragrant. Add scallion whites and cook for 1-2 minutes.
Add sugar, oyster sauce, and Red Boat Fish Sauce and stir to combine. Add in pasta and toss to coat in the sauce. Add a tablespoon of pasta water at a time to loosen the sauce and make it easier to toss. Note: you might not use all of the reserved pasta water. Use as needed and discard the rest. Top with scallion greens and fresh parmesan.
