Why this recipe works

It’s easy to opt-in for grabbing a few cans of soup from the grocery store shelves, but that may not be the best option, nutritionally speaking. On the other hand, trying to recreate a classic soup that most people have typically enjoyed from the can is often seen as intimidating. But not anymore!

This crockpot creamy tomato soup recipe works because the ingredients are simple, the instructions are easy to understand, and it’s overall better choice nutrition-wise.

In addition to those perks, the prep time is minimal, and the cooking time is perfect, making this an ideal meal for a busy weeknight with enough leftovers to enjoy the next day.  

Recipe Ingredients

  • Tomatoes – three types are used in this recipe: diced Italian from the can, tomato paste, and a large beefsteak tomato (diced).
  • Chicken broth – any brand will do, you can use chicken stock if that’s what you have on hand.
  • Roux – the white variety made by combining flour and water is used to help the tomato soup thicken.
  • Butter – added for the fat content and for helping create a robust soup.
  • Garlic – this recipe calls for fresh garlic cloves and garlic powder.
  • Heavy Cream – gives the soup a rich and silky flavor.
  • For topping – a cream swirl using heavy whipping cream and shredded parmesan cheese add the perfect finishing touches of flavor.

Variations

  • Tomato Basil – There are many variations of this soup, with the most popular being tomato basil soup. Everything is pretty much the same, except a nice helping of fresh basil is added toward the beginning and cooked with the rest of the ingredients (or dried basil works too!).
  • Chicken – Another variation adds chicken. Add two small chicken breasts to the slow cooker at the beginning of the cooking time. Before blending remove and shred. Blend the soup, then stir in the shredded chicken.
  • Veggie Packed – Add more herbs and vegetables. Celery, carrots, thyme, and oregano are a few additions that pair perfectly with this soup; no one will even know you snuck in extra vegetables after pulverizing.

Recipe FAQs

Can this recipe be made on the stovetop?

Yes! Everything can go according to the recipe; however, be sure to use a big pot and set the heating on simmer for about an hour before blending (stirring often); you may need to add additional broth.

Can I use a different flavor of broth?

You can use 5 cups of vegetable broth in substitution for the chicken broth. They are both similar in flavor.

​Does this soup freeze well?

It sure does! You can make several batches and freeze them in an airtight container or freezer bags to quickly grab for a quick meal. If you choose to keep the leftovers in the refrigerator, they will keep for about three days.
