Ingredients for Keto Gazpacho

First, you'll need some ripe tomatoes, extra bonus points if you grew them or can find some fresh local tomatoes. Next up, grab a juicy watermelon to add some sweetness and extra hydration to your soup. Don't forget that cucumber! They'll give your gazpacho that crisp and cool factor.

You can easily reduce some of the carbs in this soup by reducing the watermelon and subbing in more cucumber for a keto gazpacho that's still really refreshing. The only issue I noticed with this is it makes the color of the gazpacho slightly less appealing but if that doesn't bother you, feel free to try this hack.

A few more essentials make this soup extra tasty. Fresh garlic, shallot and a little jalapeno give this keto gazpacho a little kick.

To bring all these incredible flavors together, you'll need high-quality extra virgin olive oil.  It adds richness and depth to every spoonful along with making a nice garnish for the presentation.
