Soup Ingredients
- Two 28-ounce cans San Marzano tomatoes (whole or crushed)
- 1 stick (8 tablespoons) salted butter
- 1 yellow onion, peeled and cut into 4 chunks
- 3–4 cloves garlic, smashed (optional)
- 1 1/2 teaspoons salt
Instructions
- Make the Tomato Soup: Place the tomatoes, butter, and onion chunks in a large saucepan or Dutch oven. Heat gently until the liquid begins to bubble low, then reduce the heat to medium-low. Partially cover with a lid and let the soup simmer for 45 minutes, stirring every 15 minutes to avoid scorching at the bottom.
- Remove Onion Chunks: Using tongs, remove the large onion pieces from the pot. You may leave the smashed garlic cloves in the soup if you prefer a stronger garlic flavor.
- Blend the Tomato Soup: Use an immersion blender to puree the soup directly in the pot until it reaches your desired smoothness. Taste and adjust seasoning. If the soup is too thick, thin it with milk, water, broth, or cream as preferred—this recipe traditionally serves as-is.
- Serve: Ladle the tomato soup into bowls and serve with your choice of accompaniments such as garlic bread, grilled cheese sandwiches, croutons, crackers, or a dollop of pesto.
Notes
- San Marzano tomatoes provide a rich, authentic flavor, but any good quality canned tomatoes work well.
- Butter adds richness and a subtle sweetness to balance the acidity of the tomatoes.
- If you prefer a dairy-free version, substitute butter with olive oil and thin with vegetable broth.
- Simmering with the onion and garlic infuses the soup with deep savory notes.
- Adjust salt to taste after blending, as canned tomatoes can vary in saltiness.
- The soup can be stored in the refrigerator for up to 4 days or frozen for up to 3 months.
