Tomato Soup:

If there is one thing that I can always count on everyone in my house getting excited about for dinner it’s soup!  Especially tomato, it’s everyone’s favorite.  We also happen to love this Easy Pumpkin Soup for fall, Instant Pot Potato Soup is a year-round favorite, and Chili Macaroni Soup is perfect when it’s really chilly outside!

Tomato soup is simply a soup that’s made primarily with tomatoes. It’s great served with a variety of sides and garnishes such as grilled cheese sandwiches, garlic croutons, parmesan cheese, Italian seasoning, and garlic bread.

I always use canned whole plum tomatoes for my tomato soup.  If you are wondering why not use fresh instead, it’s because canned tomatoes are truly packed with flavor year round.  Tomato season is short, and they just don’t taste the same in the winter.  If you use fresh tomatoes you won’t get that nice rich tomato flavor you are looking for.

How to Make Tomato Soup:

This tomato soup is so easy to make in the slow cooker in just a few steps.

  • You will add two large cans of whole, peeled, plum tomatoes to the slow cooker along with your tomato sauce.
  • Add in your broth.  You can use vegetable or chicken broth for this recipe.
  • Next, add your diced onion, garlic, and seasonings.
  • Place the lid on the slow cooker and allow the soup to cook on high for 3-4 hours or on low for 6-8 hours for best flavor.

  • Once you are ready to serve the soup, you will use an immersion blender to puree it to a smooth consistency.
  • If you do not have an immersion blender, you can puree the soup in batches in a regular blender.
  • Next, stir the cream into the soup.  The cream in this recipe is optional if you’d like to keep the soup lighter.

  1. Would diced tomatoes work? We drive semi trucks and don’t have the extra space to store any more added appliances

  2. 5 stars
    I made this recipe for a church function and it was a huge hit! I added a scant amount of sugar to cut the tartness of the tomatoes and also added some butter to make it richer tasting. Will definitely be making this again and again.

    Recipe was a hit with the family! Paired wonderfully with grilled cheese sandwiches on freshly baked wheat sourdough. I served with the heavy cream on the table like a condiment.

  4. I have made this before and I absolutely love it. This time I want to freeze the leftovers. Many recipes say to not add the cream to what you want to freeze. Does that apply to this recipe? Or can I freeze it with the cream?

    1. Hi! Yes, you will want to leave the cream out of the soup to freeze. You can just add the cream in when you reheat the soup 🙂

    2. Hello, I want to try this recipe, the reason why I want to make this soup is because I have fresh basil that will spoil, I really like your recipe out of all the others I’ve seen, do you think basil will be ok in this soup?
