Fresh garden tomatoes are the star in this Slow Cooked Tomato Soup. 

Tomato soup served in a white bowl.

There are times when I need meals that I can throw together quickly. Then there are times when I can take the time to slowly bring out the flavors of the best ingredients. This is a soup that capitalizes on fresh, homegrown tomatoes and  onions, homemade broth, and low, slow cooking.

What type of tomatoes should I use?

This soup is best made with garden fresh tomatoes. Pick them fresh from your garden or buy them from a farmer’s market. Most tomatoes found in a grocery store just don’t have the full flavor you find in garden fresh tomatoes. I use a variety of tomatoes, depending on what’s in my garden. I often use roma tomatoes, early girl tomatoes, and several other varieties. 

If you have a surplus of garden fresh tomatoes, you might also want to try making oven roasted tomatoes.

What ingredients do I need?

Make this soup with fresh tomatoes, onions, carrots, chicken broth, brown sugar, salt and pepper and a bay leaf. 

I like to use a finely ground white pepper for this soup, but you can also use ground black pepper if you prefer. 

Tomatoes are often very acidic. Sugar is added in order to tame the acidity.   Sweet onions, whole carrots and garlic are added to help balance the taste.  You really want to add whole carrots here, not those small baby carrots. They just don’t have a ton of flavor.  Don’t peel the carrots.   There is so much flavor, and nutrients in the carrot skin.

How do I make the soup?

Cored tomatoes, chopped onions, chopped carrots, and whole garlic are all thrown together in a large stock pot and cooked on a low heat for about an hour.  The only attention you need to give it is the occasional stir. Cooked tomatoes in a large black pot.

Then throw everything into a food processor and puree mixture. Cooked tomatoes and onions in a food processor.

The tomato mixture is then press through a food mill or a food strainer. Tomato sauce being poured into a food mill.

  This leaves you with just the beautiful sauce.

Return the sauce to the stock pot for another hour of simmering!  Just add homemade chicken broth, or veggie broth, salt and pepper and sugar and a bay leaf.  Bring soup to a low heat and simmer for about one hour or until soup has reduced to a nice consistency.

Can I freeze this soup?

Yes, this soup can be frozen. Allow soup to cool and place in a freezer safe container. Freeze for up to 3 months. To use, thaw, heat and eat. 

What should I serve with tomato soup?

Serve this tomato soup with a grilled cheese sandwich, homemade potato chips or  ham and cheese biscuits.
