Ingredients You’ll Need

2 (28 oz) cans whole peeled tomatoes, with juices: The star of the dish! Whole tomatoes give the soup a rich base. You can also use fresh tomatoes during the summer.
2 tablespoons tomato paste: Adds depth and intensifies the tomato flavors. Look for a quality brand for the best results.
3 cups vegetable broth: This is the liquid base. You can use homemade or your favorite store-bought variety for convenience.
1 teaspoon onion powder: Adds a mild onion flavor without the hassle of chopping an onion.
½ teaspoon garlic powder: A must-have for flavor! Fresh garlic can also work; use 1 clove for every ½ teaspoon of powder.
1 teaspoon salt: Enhances all the flavors. Feel free to adjust to taste, especially if using a salted broth.
½ teaspoon black pepper: A little kick goes a long way! Freshly ground pepper adds more flavor.
½ teaspoon dried basil: This herb complements tomatoes wonderfully. Fresh basil is fantastic if available—just use a tablespoon.
½ teaspoon dried oregano: Adds a lovely earthy flavor. You can substitute it with Italian seasoning if needed.
½ cup heavy cream: For a creamy finish, making the soup incredibly smooth and luscious.
1 tablespoon butter: Adding this with the cream gives a rich mouthfeel. You can omit it for a lighter option.
1 tablespoon tapioca flour or cornstarch + 1 tablespoon of water: This slurry thickens the soup as it finishes cooking, making it heartier.
1 tablespoon sugar: If you find the soup too acidic, a bit of sugar balances the flavors beautifully.

How to Make Homemade Slow Cooker Tomato Soup

Combine the Ingredients: In your slow cooker, dump the 2 cans of whole peeled tomatoes (with juice), 2 tablespoons tomato paste, 3 cups vegetable broth, 1 teaspoon onion powder, ½ teaspoon garlic powder, 1 teaspoon salt, ½ teaspoon black pepper, ½ teaspoon dried basil, and ½ teaspoon dried oregano.
Break Down the Tomatoes: Use a spoon to gently break up the tomatoes a bit—it helps them cook down faster and releases their juices.
Cook the Soup: Cover and cook on low for 6-7 hours or high for 3-4 hours. Your kitchen will smell amazing!
Blend the Mixture: Once the cooking time is up, use an immersion blender to carefully blend the soup until it is completely smooth. If you’re using a traditional blender, allow it to cool slightly before blending in batches.
Finish with Cream and Butter: Stir in ½ cup heavy cream, 1 tablespoon butter, the previously prepared slurry of 1 tablespoon tapioca flour or cornstarch mixed with 1 tablespoon water, and 1 tablespoon sugar until everything is melted and well incorporated.
Adjust Seasoning: Taste your soup and make any adjustments to seasoning, adding more sugar if it seems overly acidic. You want a perfect balance!

Storing & Reheating

Homemade Slow Cooker Tomato Soup stores beautifully. Allow it to cool completely before refrigerating in an airtight container, where it’ll stay fresh for about 4-5 days. You can also freeze it for up to 3 months—just make sure to leave a little space at the top of the container for expansion. When you’re ready to enjoy your soup, reheat it gently on the stove over low heat until warmed through, stirring occasionally. The texture may change slightly after freezing, but a splash of cream can help bring the soup back to its creamy glory.

Chef’s Helpful Tips

Avoid over-blending; a bit of texture is nice in your soup!
Use room temperature ingredients, especially cream, to prevent curdling when adding to hot soup.
If your soup becomes too thick, just add a bit more broth to reach your desired consistency.
Taste as you go! Feel free to adjust herbs or salt to match your palate.
For a fresh twist, consider garnishing with fresh basil or a drizzle of balsamic vinegar before serving.
