Instant Pot Creamy Tomato Pesto Soup

Good morning from Charleston, SC!! Mornings are much more challenging coming from Denver where it’s two hours earlier. It’s 8am here which means, if your brain is working and you can do math (unlike me), it’s 6am in Denver. I’m suppose to workout soon before our day gets started, but I’d rather sit here and let my coffee set in. There’s some hard proof that I’m old. When I use to wake up at 6am, I felt like I was ready to conquer the world. Now I wake up and look like I’ve aged 8 years and my face is screaming for an eye mask. Aging is so fun.

Speaking of aging and trying to do it gracefully, I’m getting another profractional done on Thursday. Which means I won’t be able to leave my house until Sunday since my face will be a 1970’s horror film. How fun. When your parents and everyone in your entire life tells you not to pick at your face when you’re younger, YOU NEED TO LISTEN, YOU F*CKING IDIOT. Because it will come back to haunt you at some point and you’ll have to go to drastic measures to turn back time while having no friends because no one can stand to look at your bloody face.

How much does this conversation make you want to eat tomato soup?

This trip to Charleston to visit my girlfriends was much needed. I don’t get to see them very often since we are all over the country. But now that it’s such a short trip, I feel like we aren’t seeing much of Charleston…we’re just eating it. So much eating. Whenever I travel with my husband, we always do things because he can’t sit still. But when I’m with my girlfriends, we pretty much only think about food and working on our computers. I know that sounds suuuuupes lame, because it is, but it’s so fun to hang out with other women who have a similar job to me. I usually just spend most of my time sitting solo in my home with my bloody sketch face. But when I’m with these ladies, we get to brainstorm ideas and encourage each other to keep moving, even through self doubt. Women empowering women are pretty much the best.

But anywho, I need to get back to hanging out with them because I already head home tomorrow. And have to spend a few hours in Baltimore. What’s Baltimore like? More so, what’s the Baltimore airport like? Anything good? Is it sketch? Can I be fed and entertained for a few hours while I’m stuck there? Give me the deets because all I know about Baltimore is that it’s where the crime from season 1 of Serial in the Adnan Syed case occurred. That’s literally all I know about Baltimore. Yes, I know, I suck.

Oh, Hi! I’m Juli.

I’m a food hoarder. And a really bad dancer. If you don’t know me well, you will probably not understand my humor. Therefore, I apologize ahead of time. Thanks for listening to my ramblings of my ever-changing life and trusting my kitchen mishaps. Your trust in me is appreciated.

  1. Just this past Sunday I was wishing for a good IP tomato soup recipe because my boyfriend was craving tomato soup and I forbid him from Campbell’s! Now, here it is! Thanks!

  2. You need to check out the first degree podcast! They interview people one degree away from violent crimes. THE BEST

    1. you can do whatever you want! i haven’t tried it that way. it won’t be exactly the same so just keep that in mind. the pesto i used includes basil, cashews, pine nuts, olive oil and salt so it definitely brings a bit more flavor than just basil and olive oil

  3. BWI is pretty solid. They have a gym and a designated walking “trail” within the airport. There’s also a Silver Diner in there, which is a small-ish local chain that has gluten-free options.

  4. I am totally making this! I don’t know why every year I forget that we basically have 3 weeks of fall and then right into winter we go! Love you Colorado! Haha. And tomato soup is life.

  5. I’m pre-obsessed with this recipe. Can not wait to make it this weekend! I am well on my way to figuring out how much cauliflower is too much to eat every day because it is so versatile!

      1. Me again with the review now that I’ve eaten it. This is AMAZING. I made it as is and didn’t even need to adjust seasoning, it was perfect. I will eat anything with cauliflower and pesto involved, so I knew I’d probably like it. But I have never enjoyed tomato soup- maybe because it never tasted like this. So much better than a can for not that much effort.

        Now I want to see how it freezes so I can make it ahead!

  6. I have an electric pressure cooker wich is essentially an insta pot. I don’t have the “soup” button just time and low or high pressure. What do you think it would covert to time wise? Also, just bought your air fryer and have done tons of stuff in it. I love it!!! More recipes please! ????

    1. you know, i’ve only ever used an instant pot so it’s hard for me to say. i’m wondering if 10 min on high pressure on your electric one would work? i just can’t say for sure. and i definitely have more air fryer recipes coming your way in the future!

  7. hi, do you think that can I use same quantities but with fresh tomatoes, fresh cauliflower, fresh basil, fresh garlic, etc? And a regular pot? I don´t have the not fresh ingredients! TYVM
    I think I´m going to enjoy that!

  8. Hi! Made this recipe the poor man way (slow cooker + regular blender) and it turned out FABULOUS. Little bit more time consuming this way but the end result was delicious!! Used the slow cooker on 4hrs on high for anyone else looking to try it that way!

  9. This recipe was fantastic!!! You were right, the cauliflower does make it really creamy! And the best part, it was so easy to make!! My husband loved it as well and he had no idea there was cauliflower in it. Thank you for the wonderful recipe, this will be a staple this winter.

  10. It’s official….you’ve ruined all other tomato soup. So freaking easy with the simplest ingredients. And pesto?! Never in my life thought to add pesto to tomato soup. You evil genius, you. So. Damn. Delicious.

  11. This soup is fantastic! I LOVE tomato soup. It’s my absolute favorite and I had been really craving some but had been wishing for a lighter version of every recipe out there. The addition of the cauliflower is perfect. This soup will be going into the regular rotation from now on. Thanks so much for the great recipe!

  12. I made this yesterday for a a group of 10 women. It was a hit! I have some frozen cauliflower packets that are 12 ounces each. I initially added the suggested 16 ounces but wanted my soup thicker so I added more cauliflower for a total of 2 entire packs. It was perfect consistency for me. I also added one extra tablespoon of pesto for a more robust kick.

    I also bought an air fryer, and it is a game-changer. You have never led me wrong!

    Thank you, Juli!

  13. This was the best tomato soup recipe I’ve ever made !! I also sautéed some onions and garlic with olive oil before I put in all of the ingredients and it gave it some nice flavor . Thanks for sharing !!!!! I will 100% be making this my go to tomato soup recipe.

  14. Made this for my family as part of our festive Halloween dinner. Didn’t vary from the recipe at all. Loved it! My husband and I agreed it reminded us of Panera Bread’s tomato soup. Thanks so much! The cauliflower in it is brilliant!

  15. I made this last night for the family and it was delicious! If you’re looking for a non dairy but traditional tomato soup, this is it! Thanks Juli for posting a feel good soup!

  16. So easy and delicious!!I have made this two times in less than a week! My entire family loved this soup… my family includes 2 lovely but picky kids. Made it for the second time tonight for my husband that just had wisdom teeth removed yesterday! Thank you.

  17. What are people pairing with the soup? I’m a hearty protein kind of guy and like tomato soup, but going strict paleo soon and so grilled cheese is out of the question : )

  18. Just made this, exactly as written, for my meal prep lunches this week. SO simple and massively flavorful!!!! Threw in some cooked chicken to make it a meal. Wish I had been making this all winter long, but it will be bookmarked for many future meals. You made magic happen again, Juli!

    I might add more cauliflower next time for a thicker soup, but wouldn’t change anything about the flavor. God I love pesto.
