Slow Cooker Tomato Soup

If you'd rather have a creamy CHEESY slow cooker tomato soup...just substitute cream cheese for the heavy cream. Both are delicious and both work very well with this recipe.

  • 2 pounds fresh tomatoes blanched and skins removed then diced
  • 2 to 4 cloves of garlic crushed
  • 1/3 cup onions minced
  • OR 2 14.5 ounce cans diced tomatoes with garlic and onions
  • 1 cup heavy cream
  • 2 tablespoons fresh basil minced ~or~ 2 teaspoons dried basil


  • Place diced tomatoes, onions and garlic in a crockpot.
  • Use an immersion blender to puree about 80% (alternately put them through your blender or food processor before adding them to the slow cooker).
  • Turn heat to high, cover and cook for 4 to 5 hours (or low all day OR even overnight) then remove the lid and turn to low.
  • Stir in cream and basil.
  • Depending on the sweetness and/or saltiness of the tomatoes you used, you may want to add a touch of sugar or salt; so season accordingly.
  • Swirl in a bit of sour cream before serving if desired.

Freezer Meal Directions:

  • You can freeze this soup before or after cooking. Some cream brands freeze very well. Others will separate and look a bit weird. They do not taste any different, but it may affect the look of your soup.
  • If this bothers you just make the soup, allow to cool completely and freeze afterward.
  • Alternately, you can freeze the soup BEFORE adding the cream and add it afterward. Just make a note on the freezer bag that you'll need to add it (and have it in the refrigerator when the time comes)
  • When you defrost the soup you may need to stir very well to reincorporate the cream but I've never experienced it separating once it's been cooked.
  • Freezer friendly before cooking, 3 months. Freezer friendly after cooking, 6 weeks.
