Keto Soupe Au Pistou (Provençal Vegetable Soup)

Keto Soupe au Pistou

Jump to Recipe

This Keto Soupe Au Pistou is a low carb adaptation to the traditional vegetable soup from the French region of Provence. This is an end of summer soup that is very similar to a minestrone. When serving this soup a dollop of pistou (similar to pesto) is added to the bowl. 


In this soup we add our favorite low carb vegetables such as zucchini, leeks and a bit of tomatoes. We also add carrot to our soup as carrots always add a great flavor.  It is said though that carrots aren’t typically added to this soup because they are a winter vegetable. 

Typically green beans, canned white navy or kidney beans, and potatoes are added to this soup. While you can definitely still add green beans (these are keto-friendly), we’ve chosen to leave these out to lower the carb count. Of course potatoes and white navy or kidney beans are not suitable for a keto diet. 


Pistou is very similar to Italian pesto. The only difference is that pistou does not have pine nuts. Pistou is made with fresh basil, olive oil and parmesan-reggiano. We’ve added tomato paste to our pistou, but this is optional. 

Low Carb Pasta 

Some recipes for Soupe Au Pistou have pasta, such as elbow pasta. If you can find a low carb pasta, we recommend added this to make the soup more filling. Here are some recommendations: 

Ciao Carb High-Protein Pasta – 7g Net Carbs / Serving. This will add another 1.4g of net carbs to your overall dish per serving. 

Thinslim Impastable Low Carb Pasta – 8g Net Carbs / Serving. This will add another 1.6g of net carbs to your overall dish per serving. 

Konjac Pasta – 0g Net Carbs / Serving. This is easy to find at most grocery stores.
