Wholesome Ingredients

Your kids will never know how healthy this tasty soup is – with basil adding next level flavor.

Here’s what’s in it:

We use canned peeled tomatoes for convenience. No need to drain – they add color and a rich tomato flavor.

Carrots add vitamins, fiber, and natural sweetness.  

Onions provide a savory flavor. 

Basil leaves bring a fresh taste that both kids and adults love.

Chicken or vegetable broth creates a savory base for this soup.

Olive oil brings a rich flavor and healthy fats.

Garlic and salt bring out the best in all the ingredients. 

Fresh parmesan and basil leaves are salty and fresh and they’re the perfect finish to a warm, hearty soup. 

How to Blend Tomato Soup

When the ingredients are fully cooked and tender, it’s time to blend! Here are two simple ways to blend your soup:
1. Let soup cool a bit and transfer into a blender. Hot liquids create pressure inside the blender, so fill it no more than halfway. Place the lid on top of the blender, remove the center cap to help release the steam, and cover the opening with a dishtowel. Hold the top down and start blending on the lowest setting before increasing the speed. Be careful – steam burns are painful! 

2. Let soup cool a bit and blend directly in the Crock Pot with an immersion blender. 

 Easy Steps for making Slow Cooker Tomato and Basil Soup

  1. Add all ingredients to slow cooker
  2. Cook on low 5-7 hours, until ingredients are tender
  3. Blend until smooth
  4. Stir in milk or cream as desired
  5. Serve and enjoy!

We’ve found the flavors in this soup combine beautifully and taste even better the next day!

Stove-top version:

If you like a creamier version, omit about 1 cup of the chicken broth and add milk or half-and-half.
For broth, we recommend Better than Bouillon chicken or vegetable base.
