1 piece (~300 g) has about 500 calories.
Why estimates miss: Lasagna is a multi-ingredient dish. Cheese and meat layering means a large corner piece can be far heavier than a middle cut. Generic calorie apps undercount the hidden oil, sauce and portion — CalDesk AI's photo estimate is tuned to catch exactly this.
