Tomato and Mascarpone Soup
Today, a delicious homemade Italian tomato soup with mascarpone. And you can make it with fresh tomatoes in combination with sieved tomatoes, or if you want to keep it simple, you only use sieved tomatoes
But if you opt for fresh tomatoes, you could use all types. But I prefer Roma tomatoes, Brandywine, or heirloom tomatoes. They have just a little more flavor, and you can taste that.
This soup is super easy to make and turns a simple tomato soup into an extra creamy and delicious tomato and mascarpone soup.
What do you need for Tomato Soup with Mascarpone?
For the preparation of this Italian Tomato and Mascarpone soup, you need the following ingredients (you can find the correct amounts in the recipe card at the bottom of the blog):

- Stock - Use beef stock for a full flavor or a delicious vegetable stock if you're going vegetarian.
- Tomatoes - Tasty fresh tomatoes. Use Roma tomatoes, Brandywine, or heirloom tomatoes for the best taste. If tomatoes are not in season, you can also use a can of peeled tomatoes or, to make it even easier, replace the fresh tomatoes with 2 cups (400 ml) passata. In that case, you don't have to let the soup simmer for 20 minutes, and you don't have to strain. That's simple!
- Mascarpone - A thick and creamy cheese. It is ideal for adding to this soup, but because of its high-fat content, it won't curdle.
- Sage - This delicious herb combines very well with the tomato. Do not add too much sage; otherwise, it will overpower quickly. 5 leaves is enough. The taste of sage is warm, spicy, and slightly bitter.

- Put a dash of olive oil in a soup pan and add the chopped onion and sage. Stir for three minutes until the onion is translucent.

- Use an immersion blender to make sure all tomatoes are finely puréed. Turn on the immersion blender for 20 seconds at high speed.
- Take a clean pan and put a sieve on it. Pour the puréed Italian tomato soup on top and press the soup through the sieve with a spoon. The seeds and skins remain behind, and you throw them away afterward. Add the sugar to the soup. Add the sieved tomatoes to the soup. Mix and bring everything to a boil. Taste the soup and season with salt, pepper, or additional sugar if necessary. Ladle the soup into a bowl and add a tablespoon of mascarpone. Serve immediately.
FAQ
You can add diced tomatoes for a bite to the soup. A drizzle with balsamic cream or olive oil is also delicious. Or add a tablespoon of pesto for even more flavored soup.
The tomatoes may be a bit more sour than sweet. You can solve this by adding sugar or a teaspoon of baking soda. Baking soda neutralizes the acidity of the tomatoes.
Add spices. Basil, rosemary, and thyme give more depth. Chives and parsley give the soup a slightly fresher taste. And adding salt and pepper can also improve the taste.
