This slow cooker tomato soup is an absolute delight as it’s packed with a ton of flavor and is super easy to prepare.

Slow Cooker Tomato Soup

The flavors of this soup will have you going back for seconds or even thirds. It features the traditional tomato flavor combinations that you know and love, such as basil, oregano, and even bell pepper.

I love making this soup as it’s super easy and tastes so much better than the store-bought canned tomato soup. The best part is that you can easily alter the recipe to better suit your taste buds.

This soup is great all year round, so it’s the perfect one to keep at the top of your recipe pile. I love making it when I need to feed quite a few people but running low on money.

The best part about making this slow cooker tomato soup from scratch is that you can decide on the flavorings.

For example, if you like your soup herby,  add more herbs. You can even add some bacon if you want to. Some grated parmesan is always an excellent addition.

Tomato Soup with Bread

This soup is excellent without any side dishes, but I do love having it with some fresh bread or some croutons. You could even make some fried cheese sticks to dip into the soup.

Cooking Tips

  • You can omit the sugar if you don’t think it is needed. However, the sugar will help reduce the acidity of the tomatoes.
  • If you’re using fresh tomatoes, then make sure you remove the skins as they will cook to be quite leathery.
  • Bacon is an excellent addition, but I highly recommend that you dice and fry it first.
  • This soup is best pureed, so I highly recommend that you don’t try to make it chunky.
  • The chicken stock can be replaced with vegetable stock, and the cream left out if you want this to be vegan or vegetarian-friendly.
