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:
- Prep the veggies
After you’ve rinsed the veggies, give them a good chop making sure they are even shapes and sizes. - 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. - Make it smooth
Once the vegetables are cooking down and tender, insert an immersion blender and blend until the soup is smooth. - 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. - 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.

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:
- 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.
- Pack it into the thermos and seal.

I’m not a fan of tomato paste. Is there a way I can substitute tomato sauce?
MOMables-Laura
Yes, but the tomato flavor won’t be as strong. I would swap the tomato paste for 1/2 cup tomato sauce.
Sandy
Yogurt, strawberries, and cheese or tacos or ravioli.
I’m looking forward to trying this recipe for us!

My toddler loves blueberries frozen or fresh & really enjoys zucchini lasagna. I prepped it the night before.
Angela Dickson
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”.
Bonnie Norton
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.
Marion Millan
My little ones love Pasta Fagioli. I love that it is quick and easy to make in the crockpot.
Theresa
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.
Pam
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?
MOMables
The recipe you see in the post is what is pictured. It is very different than canned soup.
Susannah
My little ones love baked chicken nuggets and corn.
Colleen
We serve breakfast tacos with eggs, mild pico de gallo, and flour tacos…for dinner!

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