Why use mascarpone cheese in soup

Mascarpone cheese is often used in Italian desserts, but it is the PERFECT cheese to add to soups because it adds richness and creaminess. Especially to soups like tomato soup that could use a little fat and creaminess to balance out their acidity.

This is a GREAT recipe to use up mascarpone cheese while making something that is nutritious, hearty, comforting, and delicious.

Substitutions for mascarpone

Mascarpone cheese typically has 2 ingredients: heavy cream and lemon juice or citric acid (the acid component is what makes the cheese solid).

If you don't have mascarpone cheese, you can use heavy cream (aka double cream or whipping cream) or a dollop of sour cream to add richness and creaminess to soups... but since you're here, you're probably looking for a soup with mascarpone specifically.

What to serve with pureed tomato soup

A grilled cheese sandwich is the classic idea for what to serve with tomato soup. And for good reason! The melty cheesy balances out the tanginess of the soup, and the crispy buttered toasted bread is so delicious dunked into soup.
