Yes, you can make Greek yogurt buffalo chicken dip with low fat Greek yogurt. That being said, I still recommend making this dip using full-fat Greek yogurt. The full-fat yogurt is more forgiving, because the higher fat content will help protect it from separating when heated. However, I have also tested this recipe using low fat yogurt, which also worked well and tasted great. Just be sure not to overheat the dip!
