How Many Calories in Mascarpone? Nutrition Facts & Macros

A tablespoon (28 g) of mascarpone has about 122 calories. Per 100 g it has 435 calories (1820 kJ), and nearly all of them come from fat (44.5 g), with 4.6 g of protein and 4.3 g of carbohydrate. That is well above cream cheese (350 kcal) and nearly three times ricotta (150 kcal).

Mascarpone is a fat-rich ingredient rather than a protein food: 44.5 g of fat per 100 g, of which 29.5 g is saturated, against just 4.6 g of protein. Cholesterol is 123 mg per 100 g. It does provide 161 mg of calcium and a useful 412 µg of vitamin A. Sodium is low for a cheese at 70 mg, so the salt is not the issue — the portion size is.

Mascarpone has 4.3 g of carbohydrate per 100 g, which works out at about 1.2 g per tablespoon (28 g). All of it is lactose left in the cream, and there is no fibre, so net carbs are the same 4.3 g. That is less than cream cheese (5.52 g) and more than brie (0.45 g).

At 435 kcal per 100 g, mascarpone is hard to fit into a deficit in any quantity. Even a single tablespoon (28 g) costs 122 calories and brings 1.3 g of protein, so it does very little for fullness. Use it as a flavour accent rather than a base, or swap part of it for ricotta (150 kcal per 100 g, 7.54 g protein) where the recipe allows.

Yes. With 4.3 g of carbohydrate per 100 g, a tablespoon (28 g) adds only about 1.2 g of net carbs, while its 44.5 g of fat makes it one of the easiest ways to reach a keto fat target. It works in keto tiramisu, whipped with cocoa as a dessert, or stirred into coffee.

Mascarpone is made from cream, cream cheese from milk, and the numbers follow: 435 kcal against 350, and 44.5 g of fat against 34.44 g. Cream cheese returns more protein (6.15 g against 4.6 g) and carries slightly more carbohydrate (5.52 g against 4.3 g). Mascarpone is sweeter and rounder, which is why it belongs in tiramisu; cream cheese is tangier and more useful for cooking and spreading.
