Detailed Directions and Instructions
Step 1:
In a large pot, combine the canned tomatoes (including their juices), the halved onion, peeled garlic cloves, and unsalted butter.
Step 2:
Place the pot over medium heat and bring the mixture to a gentle simmer.
Step 3:
Once simmering, reduce the heat to maintain a gentle simmer. Allow the mixture to cook uncovered for about 45 minutes. Stir occasionally, breaking up the tomatoes with a spoon as they soften.
Step 4:
After 45 minutes, remove the pot from the heat. Discard the onion halves and garlic cloves.
Step 5:
Using an immersion blender, purée the soup directly in the pot until smooth. If you don’t have an immersion blender, carefully transfer the soup in batches to a regular blender, puréeing until smooth and returning it to the pot.
Step 6:
Taste the soup and season with salt as needed.
Step 7:
If the soup is too thick for your liking, you can thin it with a bit of water or broth until it reaches your desired consistency.
Step 8:
Reheat the soup over low heat if necessary, then serve hot.
Notes
Note 1:
San Marzano tomatoes are preferred for their rich flavor and low acidity, which enhances the soup.
Note 2:
For an added depth of flavor, consider incorporating fresh basil or oregano during the cooking process or as a garnish when serving.
Note 3:
Be cautious when using a regular blender; hot soup can splatter. Allow the soup to cool slightly before blending, and blend in small batches.

Cook techniques
Simmering
Simmering involves cooking the mixture over medium heat, where small bubbles rise slowly to the surface. This technique helps to meld the flavors of the ingredients without boiling, which can cause them to break down too quickly.
Blending
Blending is the process of puréeing the soup until smooth. An immersion blender is ideal for this purpose as it allows for easy blending directly in the pot, while a regular blender requires careful transferring of the hot soup in batches.
Seasoning
Seasoning is the addition of salt to enhance the flavors of the soup. It’s important to taste the soup after blending and adjust the seasoning as needed to achieve the desired flavor profile.
Adjusting Consistency
Adjusting the consistency of the soup can be done by adding water or broth if it is too thick. This technique allows you to customize the texture to your preference, ensuring a more enjoyable dining experience.
Reheating
Reheating involves warming the soup over low heat if needed before serving. This technique ensures that the soup is served hot, enhancing the taste and providing a comforting experience.
FAQ
Can I use fresh tomatoes instead of canned San Marzano tomatoes?
Yes, you can use fresh tomatoes, but make sure to peel and core them before using. You might need to adjust cooking time based on the ripeness of the tomatoes.
What if I don’t have an immersion blender?
If you don’t have an immersion blender, you can safely use a regular blender. Just be careful when transferring the hot soup in batches, and allow it to cool slightly to avoid splatters.
Can I add other vegetables to the soup?
Absolutely! You can add vegetables like carrots or bell peppers. Just cook them along with the onions and garlic before adding the tomatoes.
How long can I store leftover soup?
Leftover soup can be stored in an airtight container in the refrigerator for up to five days. It can also be frozen for longer storage, typically up to three months.
Is this soup suitable for vegans?
No, due to the use of unsalted butter. However, you can substitute the butter with a plant-based oil or vegan butter to make it suitable for vegans.
