How Many Calories in Fettuccine Alfredo?

1 plate (~300 g) has about 800 calories.

Why estimates miss: Fettuccine Alfredo is a multi-ingredient dish. The butter-cream-parmesan sauce is the main calorie driver, so richer versions climb fast. Generic calorie apps undercount the hidden oil, sauce and portion — CalDesk AI's photo estimate is tuned to catch exactly this.
