Creamy and loaded with bright, fresh flavors, this Easy Keto Tomato Basil Soup will quickly become a new family favorite – especially served with my Keto Cheesy Herb Muffins!!!
When I was a kid I used to love condensed tomato soup from a can, which my mom would usually serve alongside grilled cheese sandwiches made on cheap white bread with lots of butter. It was one of my favorite lunches and tasted even better when we’d just come inside from playing in the snow and were frozen to the bone. There was nothing better than having the day off from school for a snow day and trudging in and getting hit in the face with that sweet and pungent tomato soup smell at lunchtime.
Soup from a can isn’t something I’ve had in many years, but when I set out to create a tasty and easy keto tomato soup recipe, I started with the flavor and smell I remembered from my childhood in mind. Since my taste buds have gotten more discerning over the years, I wasn’t quite as enamored with the basic flavor of the tomato soup as is, so I threw in some dried basil and finished it with some pesto I had kicking around in the fridge at the end.
The addition of basil and pesto really took this already tasty keto tomato soup to the next level of “this is so good that I can’t stop eating it!”
Since we’re rounding the corner into Spring, this is a great transition soup that is still creamy and comforting, but also sports the brighter, fresher flavors that we’re all starting to crave about now. And you won’t have to stand over the stove for hours to make it, leaving you more time to enjoy the warmer (maybe) and sunnier (hopefully) days ahead.
The tasty looking muffins that you see in the photos are the Keto Cheesy Herb Muffins that I posted recently – and they are amazing. Tender and flavorful, they are the perfect accompaniment to this easy Keto Tomato Basil Soup and stand in perfectly as a keto replacement for the grilled cheese sandwiches of my childhood.
It’s my hope that this easy low carb tomato soup recipe will bring back pleasant childhood memories for you as it did for me, but even if it doesn’t, or if you haven’t been a fan of tomato soup in the past – I hope you’ll give it a try anyway and report back!
Easy Keto Tomato Basil Soup Recipe Note:
Be sure to use good quality canned tomatoes for this recipe since there aren’t a lot of other ingredients to mask the bitter or metallic flavor that you may get with low grade canned tomatoes. Homegrown, organic and/or San Marzano region tomatoes will typically give the best flavor. I use Cento brand (not getting paid for this, just really like Cento) when I can find them and I’m never disappointed – but any brand of tomatoes grown in and imported from Italy will likely yield delicious results.
That’s not to say this easy keto tomato basil soup won’t still be tasty made with U.S. tomatoes, just maybe not quite as good as it could be.
