Tomatoes and vegetables simmer away all day until tender, then they’re pureed to make this ultra creamy, vibrant tomato soup that is secretly loaded with veggies! Your kids will never know!

I see all kinds of recipes on Pinterest showing parents how to sneak more vegetables into their kids’ food. I pin those kinds of recipes for myself. I hate vegetables. I mean, I’m okay with potatoes. Corn. Cooked carrots and peas are tolerable. But aside from that? No. Way.

Because of this I was always adamant that my child would eat and enjoy her vegetables. When she was a baby, I made sure that she got her fair share before she would get anything remotely sweet. Broccoli. Cauliflower. Green Beans. Squash. The girl eats anything. And, to this day, she will take vegetables over anything else on her dinner plate. I actually have to mix the vegetables in to her food so she eats the rest, and then she gets upset when she sees that others around her get to have their vegetables in a separate pile.

So this recipe is for me. Though my 21 month old absolutely devoured it.

I know, as a somewhat responsible adult, that my body needs a certain amount of these kinds of things to function the way I want it to, so I force myself to eat my vegetables (as long as it’s not broccoli, cauliflower, green beans, brussel sprouts, squash, etc., etc., etc……).

And that is why I love recipes like this one. Recipes that make me feel like I’m eating a seriously decadent tomato soup and none of the vegetables that are discreetly pureed and hidden in it.

I changed the recipe a bit to add in even more vegetables, because when I made it there seemed to be a good amount of liquid for the amount of vegetables the recipe called for. I also added some additional spices and salt. The recipe allows for so much flexibility that you can add any vegetables you want as long as there is enough liquid to cook them in.

*Note: the milk and flour mixture can easily be omitted to make this a gluten and dairy free option. Even without that step, the soup is rich and creamy from the pureed vegetables!

    Hi Ashley, love your recipe and love adding extra “hidden” veggies when possible. I also add red/yellow/orange peppers, but not green. Instead of flour and milk, I add coconut milk/cream or almond milk and tapioca starch to thicken if needed. We like a thinner soup so usually don’t add the thickener. Lots of rain lately so today is “tomatoe soup day” 🥰
    I love your thinking when cooking/baking….recipes should be a guide line, starting point. Changes are what make it yours! I have always been one to use what’s on hand. That’s how new ideas are born. My husband/kids will say “that was great, can we have it again? My reply is usually, “not exactly the same, but I can try” 😏
    Keep up the great work

        Hi Angela! This is a slow cooker recipe and not for the Instant Pot, but it can easily be made on the stove top too! Just cover and simmer until the vegetables are all tender, then puree with an immersion blender.

    I’m trying to used less commercially canned and processed foods. Would it be possible to use fresh tomatoes. I would probably use home canned tomatoes, if I had them. Otherwise I love the idea of extra vegetables and it sounds delicious.

    I am just wondering why the sugar is so high. After looking at the ingredients I don’t see any that would make it such a high number. . .

    I love how much good stuff is packed in here! I am a big fan of “hidden” fruits and veggies in things. My husband refused to eat vegetables for a long time I had to get super creative with hiding them! 🙂

      I can tolerate cooked corn, peas, carrots, potatoes and peppers, and I don’t even really enjoy them all, so I’m always looking for ways to sneak them in! I’m old enough to know what I should be eating and why, but still not willing to get very adventurous.
