Tomato Soup Ingredients
You’ll need the following ingredients for this tomato soup:
- butter
- yellow onion
- garlic
- dried thyme
- red chili flakes
- canned San Marzano tomatoes
- chicken or vegetable broth
- sugar
- dried bay leaves
- salt and black pepper
You’ll also need an immersion blender or a high-speed blender for pureeing the soup.
Why Use San Marzano Tomatoes?
San Marzano tomato is a type of plum tomato, and it’s thinner and more pointed. The flesh is much thicker with fewer seeds, and the taste is stronger, sweeter, and less acidic.
Most major grocery stores will have San Marzano tomatoes. I found mine at my local Costco.
Substitute for San Marzano tomatoes? Whole peeled canned tomatoes can be used in their place. The texture will be the same but the taste will be slightly different.
How to Make Tomato Soup
In a dutch oven or a soup pot, heat butter over medium heat. Add onions and cook until soft. Stir in garlic, thyme, and chili flakes, and cook until fragrant.
Add tomatoes, broth, sugar, bay leaves, salt, and pepper. Bring to a simmer. Reduce heat and cook, uncovered, for 20 minutes.
Discard bay leaves. Remove soup from the heat and using an immersion blender, blend the soup into a smooth consistency.
Tips for Making Tomato Soup
- Use a nonreactive soup pot, such as stainless steel, ceramic, or metal with enamel coating for cooking the soup since it’s acidic.
- For a smoother consistency, use a high–speed blender instead of an immersion blender for blending the soup.
- Do not cover the soup when simmering or it will be runny.
- Add more flavor to the soup by stirring in fresh basil, half and half, or freshly grated Parmesan cheese.
- Use best quality canned tomatoes, such as San Marzano.
- For less heat, use 1/8 teaspoon of chili flakes.
