Preparation
Whole-milk mozzarella is 299 kcal per 100 g, the lightest of the common melting cheeses here, and the reason is water: fresh mozzarella is a wet cheese, and water displaces fat. That is also why it browns less and goes stringy rather than oily. Low-moisture mozzarella, the kind sold shredded for pizza, is drier and reads higher — this row is the whole-milk one.
Logging this food
A cup shredded is 112 g and 335 kcal; an ounce is 28 g and 85; six slices are 170 g and 508. Fresh mozzarella sold in brine should be drained before weighing. On a home pizza, 100 g of mozzarella is a generous covering and 299 kcal — usually less than the base underneath it.
Swaps and alternatives
Cheddar is 403 kcal per 100 g and Swiss 393, so mozzarella saves around 100 per 100 g against either. Feta at 265 is lighter still and works in the same places a fresh mozzarella does. Against cream cheese at 350, mozzarella carries nearly four times the protein for less energy.
