You’ll never guess the secret ingredient that is in this keto zuppa toscana soup! It tastes like potato, it looks like potato, it acts like potato… but this is low carb zuppa toscana, so we know it’s not potato. Can you guess what it is? This recipe is based on my Italian sausage and kale soup, but that one doesn’t have a potato swap, which I thought was much needed for the best healthy zuppa toscana equivalent. Plus, in this version there’s an easy swap that makes it a whole30 zuppa toscana as well. Keto zuppa toscana is a delicious and filling meal all by itself, but if you want a simple side and have room in your macros, try keto fathead dinner rolls, keto garlic bread, keto cheddar bay biscuits, or keto chaffles on the side.

What Is Zuppa Toscana?

Zuppa toscana means “Tuscan soup”. In the U.S. today, probably the most popular rendition is the one from Olive Garden. The main ingredients in the classic version are sausage, onions, bacon, garlic, broth, cream, potatoes, and kale.

For this keto zuppa toscana recipe, we’re swapping the potatoes for rutabagas!

Keto Zuppa Toscana Ingredients

This keto zuppa toscana copycat recipe is made with just 8 ingredients:

Ground Italian sausage – Look for a pork sausage with minimal preservatives. You could also use turkey Italian sausage. Bacon – Make sure your bacon is sugar-free. Sweet onion – Sweet onion is best, but white or yellow will also work. Garlic – Use fresh or jarred garlic. Chicken broth – I like using free-range broth for best flavor. Rutabagas – This is the secret ingredient. Tastes like potatoes (especially in soup and dishes like roasted rutabaga)! Sea salt and black pepper Curly kale – Chop kale and discard any big chunks of stem. Heavy cream – But for paleo whole30 zuppa toscana, swap this with coconut cream instead.

How To Make Keto Zuppa Toscana Soup

Brown sausage. In a large skillet, brown sausage and cook until cooked through. Drain any fat and set aside.

Brown bacon. In a large dutch oven, brown bacon until cooked through and drain any fat.

Saute aromatics. Add onions and garlic to dutch oven and saute for a few minutes.

Simmer. Add chicken broth, rutabagas, salt and pepper and bring to a boil over high heat. Reduce heat to low and simmer until rutabagas are tender.

Add kale and sausage. Add chopped kale and cooked sausage to dutch oven and simmer for a few minutes until kale is tender.

Make it creamy. Stir in heavy cream and heat through before serving.

Can you eat zuppa toscana on keto?

No, traditional zuppa toscana is made with potatoes, which makes it not keto friendly. Many creamy soups are also thickened with flour, which adds carbs and gluten. This version swaps out the potatoes and uses no flour. It’s thick and creamy without it.
