Creamy Slow Cooker Tomato Basil Soup

We’re starting the new year with some freezing temps here in Denver. Today’s high is 1 whole degree-brr! That means soup time! I’m excited to share my creamy tomato basil soup with you. This is a wonderful set-it-and-forget-it soup. Made with beautiful San Marzano tomatoes and fresh herbs, this is an easy way to get your veggies in and enjoy a belly warming soup.



  • 3 large unpeeled carrots, quartered and roughly chopped
  • 1 whole onion, roughly diced
  • 4 small cloves garlic, roughly chopped
  • 28 ounce can of San Marzano whole tomatoes
  • 1 teaspoon fresh thyme
  • 10 fresh basil leaves, roughly chopped
  • 2 bay leaves
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 teaspoon dried oregano
  • 4 cups chicken stock
  • 3 tablespoons butter
  • 1 tablespoon olive oil
  • 4 tablespoons (gluten free) all purpose flour
  • 1/2 cup cream
  • 1/4 cup shredded Parmesan cheese

  2. Once cooked, remove bay leaves and transfer half of the soup to a blender and puree for about 1 minute. Transfer puree to a large bowl and repeat the process with the second half of the soup.img_20170106_165909700
  3. Once soup is pureed, create your roux. Melt butter and olive oil in a large soup pot. Once melted, gradually stir in the flour and cook over medium-high heat for at least three minutes, stirring constantly.img_20170106_170620238
