It feels like winter has been dragging on forever. So much so, that it’s March and I’m coming up with a keto Tomato Bisque recipe. That’s where we’re at here in the Northwest.
But this low carb tomato soup recipe could be the best thing to come out of this nasty, awful winter.
Seriously, this is probably my favorite keto soup recipe of all time and one I’ll be making for many winters to come.
A Creamy Tomato Bisque That is Actually Keto
When I came up with this low carb tomato bisque recipe, I knew I wanted it to be more than just a stripped down version of the original. I wanted it to be better than the original.
First, I wanted a delicious flavor base of diced vegetables slowly simmered in butter. And so I set out to develop a keto-friendly mirepoix.
Usually, the vegetable mixture in this type of cuisine starts with onions, carrots, and celery in 2:1:1 ratio with twice as much onions as carrots or celery.
But, carrots aren’t really keto-friendly, so I decided to throw them out. In their place, I added fresh garlic.
Add this mixture to a good-sized portion of butter, and we have a delicious low carb mirepoix.
Great Keto Tomato Bisque Starts With Great Tomatoes
In our keto tomato bisque recipe, the tomatoes are the star of the show. We didn’t spend a bunch of money on steak or fancy cheese, so I say, let’s up our game with the tomatoes.
San Marzano tomatoes are known by many as being the best tomatoes on the planet, and they are worth the extra investment. They’re not really too expensive, though. We get ours for under $4 a can from Amazon.
But, you can find San Marzano’s at the grocery store too. Just make sure you buy whole peeled tomatoes (as opposed to the chopped variety) if they are available.
Simmer Your Keto Tomato Bisque To Develop Rich, Complex Flavors
I feel like this is such a missing step in so many of the low carb tomato bisque recipes that I’ve looked at. They simply try to rush things.
And when you’re creating the best keto tomato bisque recipe, you just can’t speed things up too much.
So here’s what we do…
After cooking our low carb mirepoix for about 8 minutes, we add in a couple of cans of chicken broth, our San Marzano tomatoes, and a few fresh herbs.
For this tomato bisque recipe, I chose to use fresh parsley, thyme, and a bay leaf. You could also use fresh basil, if that’s your thing. Definitely feel free to experiment a little.
Next, we simmer the above mixture for about 30 minutes to really develop the flavors.
After the simmer, allow the mixture to cool slightly before transferring it to a blender (in batches) and puree until smooth.
Return the tomato mixture to the pot and heat over medium heat.
Add the heavy cream and season with salt and pepper. Easy Peasy!
Okay, shameless plug time…
