Creamy tomato bisque that’s totally dairy free! This lovely low carb roasted tomato soup is thick and delicious, and full of healthy fats. So easy to make and the kids loved it too! Paleo and keto-friendly. This post is sponsored by California Avocados.
There are some recipe ideas that I know from the beginning will be amazing. And then there are some that take me by surprise, because I didn’t expect to like them that much. This delicious dairy free tomato bisque falls into the latter category. I knew it would be tasty enough but I didn’t expect to love it. And love it I did. It’s a fantastic summer soup recipe, perfect for using your fresh garden tomatoes.
What makes this dairy free soup so thick and rich and creamy? Avocados! Hooray for avocados.
I’ve long noticed that avocados have a magic thickening power. Every time I blend them into something like a soup or a sauce, I have trouble actually getting the mixture thin enough to pour. They are way better than bananas as a thickener and they happen to be better for you too. More potassium, more fiber, more heart healthy fats.

Seriously, dude, those avocados are amaze-balls. Especially those perfect California Avocados. We have about 1 month left on Cali Avo season and this makes me very very sad. If you see me crying in a corner in the next week or two, it’s because I have to say goodbye to my favourite green fruit for the next few months.
How To Make Roasted Tomato Bisque
Anyway, I am trying to make the most of what’s left of the season and a light summery soup that used some of my homegrown tomatoes seemed like just the thing. These tomatoes are so perfectly sweet already, but roasting them brings out even more sweet summer flavor. So I tossed them with some oil, salt, and pepper and roasted them for about 30 minutes.
After that, it was ridiculously easy. I simply blended the tomatoes with an avocado and some chicken broth until it was a thick but pourable consistency. I rewarmed it gently in a pan and voila! Our low carb tomato soup was ready to go.
Here’s the thing about using avocados as a thickener. You can play up the flavor or play it down, according to your taste. Two of my kiddos like avocado but the third one does not. I didn’t tell them that this roasted tomato soup contained any such thing and they all happily gobbled it down.
But you can also play up that creamy avocado flavor by adding some slices as garnish and perhaps a little chipped cilantro. Give it a little southwestern edge, as it were. It’s really up to you.
So there you have it. A healthy dairy-free tomato bisque recipe. You need this in your life!

This looks amazing. A local chain has a pepper jack tomato soup that I miss since switching to Keto woe. I know it would no longer be dairy-free, but I will try this and add in some shredded pepper jack!

Hey if you don’t have to be dairy-free, then do what you like. I don’t either but I do love how avocados thicken things without ever needing heavy cream or cream cheese.
Betsy says
Wow! I love tomato soup, and I never would have thought to add avocado for thickening. I’ll definitely try it before the season is over. Thanks!

Hi Carolyn! You can always freeze a bunch of avos so you don’t have to go without…😃👍🏻❤️
Amy Proctor says
Hi Carolyn, just wondered if you peeled the tomatoes at all before or after roasting? Can’t wait to try this.
Carolyn says
I don’t bother for roasted tomatoes. They taste good with the skin in this case and they hold together better.
Tammy Kaylor says
Hi Carolyn,
I love some basil in my tomato soup. Wondering if I could sub basil for cilantro without altering the dish too much.
Carolyn says
Sure thing! It would be amazing.
Michelle says
Do you think this would freeze well?
Carolyn says
I honestly didn’t try so I can’t say for sure.
Kay says
I just made this. Not only was it delicious, it froze beautifully into single serve cups! Yum!
Carolyn says
So glad to hear that!
Sarah says
Just made this- it’s delicious! I ended up going back and roasting another pound of tomatoes- I think my avocado was too big so my first try tasted a little heavy on the avo- adding in more roasted tomatoes worked perfectly!
Fiona Jones says
This is really delicious & simple to make. My recommendation: make a double batch!
We’re new to keto & this site gives delicious ideas. Before going keto, we used to eat vegetarian half the week. I really relish keto veg recipes. Most aren’t filling enough for my husband. I’d welcome more!
Thanks for this. It’s delightful.

Glad you liked it!
