On nights when you need an easy, satisfying dinner, this Creamy Tomato Soup recipe with hidden veggies is the perfect solution.

Something about the combination of tomato soup and grilled cheese sandwiches will never get old, and in this recipe, I show you how to make the classic soup into a healthier version that’s just as delicious.

I also love that everything gets cooked down in the slow cooker, so you can go about your day while dinner makes itself.

Slow Cooker Tomato Soup

This slow cooker tomato soup offers more flavor and creaminess than classic tomato soup, thanks to veggies. Bell pepper, carrots, and zucchini help give it more volume and nutrition and when blended, they give this soup the perfect smooth and creamy texture.

The final step is to whip up a few grilled cheese sandwiches. Toasted buttery bread with melted cheese and creamy tomato soup for dipping is the epitome of a delicious and simple meal the whole family will enjoy.

Creamy Tomato Vegetable Soup Ingredients

Here’s everything you need to make this slow cooker tomato soup

  • olive oil
  • red bell pepper
  • carrots
  • zucchini
  • celery
  • onion
  • garlic
  • tomato paste
  • crushed tomatoes

What Other Veggies Can You Use?

You can also add other vegetables to this homemade tomato soup like cauliflower, eggplant, and seeded yellow squash. They absorb the tomato flavor, easily cook down with the other veggies, and blend into a smooth soup.

However, be careful with adding veggies with a ‘powerful’ flavor. Things like Brussels sprouts, broccoli, cabbage, spinach, and kale can add a slightly bitter flavor and unpleasant green color.

How to Make Creamy Tomato Vegetable Soup in the Slow Cooker

To make this tomato vegetable soup, you will need a slow cooker, immersion blender, or regular blender. It’s a very simple recipe that goes like this: 

  1. Prep the veggies
    After you’ve rinsed the veggies, give them a good chop making sure they are even shapes and sizes. 
  2. Grab your slow cooker
    Add the olive oil, veggies, tomato paste, crushed tomatoes, and vegetable stock to the slow cooker dish. Cover and set to cook for 6 hours on low. 
  3. Make it smooth
    Once the vegetables are cooking down and tender, insert an immersion blender and blend until the soup is smooth. 
  4. What if I don’t have an immersion blender?
    If you don’t have an immersion blender, allow the soup to cool down to room temperature before transferring half to a blender and processing until smooth. Transfer the blended soup to a large soup pot. Repeat with the remaining soup. 
  5. Grab the bread, cheese, and butter
    Whip up a few grilled cheese sandwiches then slice and serve them with a hot bowl of tomato soup.

What to Serve with Creamy Tomato Vegetable Soup

While I love a good grilled sandwich with tomato soup, it isn’t the only option to serve with this soup. Other yummy combinations would be: 

  • Grilled Cheese Dippers
  • Loaded Baked Potatoes
  • Bacon & Spinach Mini Quiches
  • Pizza Biscuits
  • Homemade Whole Wheat Biscuits

How to Pack Tomato Soup for a Thermos Lunch

This recipe is another one of my kid’s favorite school lunches. They love dunking the grilled cheese strips in hot soup, especially during the winter months.

Each batch of this tomato soup yields 8 servings, so that’s two meals for one! Here’s how to pack the soup in a thermos container and keep it hot even on the coldest days:

  1. Heat the soup in the microwave or on stove-top to a boiling point (212F and 100C). You should not be able to test if the food is hot enough.
  2. Pack it into the thermos and seal. 

Watch this quick video to see how to keep food hot all day in a thermos.

What’s your family’s go-to meal that also pleases the younger kids?

    I’m not a fan of tomato paste. Is there a way I can substitute tomato sauce?

      Yes, but the tomato flavor won’t be as strong. I would swap the tomato paste for 1/2 cup tomato sauce.

    Yogurt, strawberries, and cheese or tacos or ravioli.

    Our go to recipe is fideo, tomato based broth with spaghetti like noodles. We’ve also started adding pureed veggies mixed in it. My 16 month old loves slurping the juice from the bowl after eating the noodles. And she says “Mmmm”.

    My kids love it when I make street tacos! They love the small corn tortillas that fit perfect in their hands. They love to add their own toppings to suit their tastes.

    My kids love Mac and cheese and I love to add puréed or finely chopped veggies to it to boost nutrition. My favorites are butternut squash and cauliflower.

    I may try this. I have looked and looked for a soup like Campbell’s tomato soup. How does this compare? Have you added milk?

      The recipe you see in the post is what is pictured. It is very different than canned soup.

    Chili, spaghetti, or any form of tacos are always winners in our house.
