Low Carb Tomato Soup: Easy and Delicious
This is our favorite and the only low carb soup we’ll eat. I LOVE tomatoes but my family only likes them when they’re cooked in things like pizza sauce or spaghetti. This low carb tomato soup (roasted tomato basil soup), however, they all get excited about when I make it. It’s SUPER easy, and no heavy cream (dairy-free), and no sugar!!!

This is the perfect keto tomato soup recipe for those who are counting net carbs or are on a keto diet.
First you’ll need tomatoes. This recipe is adjustable to make as much or as little as you like.
Low Carb Tomato Soup Ingredients
- You’ll need 12 medium tomatoes
- Olive Oil
- Salt & Pepper
- Fresh Basil Leaves
You can use Roma tomatoes, regular tomatoes, or a mixture of both. If you use Roma tomatoes you will probably want to add more. In these photos I used a mix and I used about 20 tomatoes as most of them were Roma’s from my garden.

Low Carb Tomato Soup Instructions
Cut the tomatoes in 1/2 and place in a single layer on a cookie sheet or two (or a pan of your choice).
Drizzle with olive oil (about 2-3 tablespoons)
Add salt and pepper to taste (I sprinkle salt & pepper over all the tomatoes)
Bake in the oven at 400 degrees for approximately 25 minutes. When you roast the tomatoes it intensifies the flavor!
Now that you have roasted tomatoes, place the tomatoes in a blender (or you could use an emersion blender) and add fresh basil leaves. Add as many or as few as you like. The more you add, the stronger the basil flavor.
Serve immediately. If it needs a little warm up cook it in a saucepan or soup pot or place in a crock-pot to simmer and keep the flavor growing and serve later.
We serve with fresh Parmesan on top. Enjoy!
This is perfect paired with a grilled cheese sandwich or crusty bread and butter!
Store leftovers in an airtight container in the fridge.

Notes
How much basil do you add?
You can add as much or as little as you like. I would suggest starting with about 3 leaves and tasting it, you can always add more.
