⏲ How to make keto zuppa toscana
This is an overview of the recipe’s instructions. The full instructions can be found in the recipe card at the bottom of this post.
- Cook Bacon: Cook the chopped bacon until crisp and then transfer it to a paper towel-lined plate. Carefully spoon out and discard the bacon grease, but do not wash the pan.
- Cook Sausage: In the same pan, cook up your ground sausage until browned then transfer that to a separate paper towel-lined plate. Spoon out and discard the excess grease but, again, do not wash the pan.
- Prepare Soup: To the same pot with some melted butter, add your minced garlic and spices and saute until fragrant before increasing the stovetop head and adding in chicken broth, heavy cream, and shredded Parmesan. Bring the mixture to a simmer, add in the quartered radishes, and decrease the stovetop heat. Simmer until the radishes are fork-tender.
- Serve And Garnish: Stir in your browned sausage and chopped kale and continue to simmer until the kale wilts before serving the soup in bowls and garnishing with the bacon crumbles.

👉 Ingredient substitution suggestions
- Minced Garlic: Use ½ teaspoon garlic powder in place of the 2 teaspoons of minced garlic that the recipe calls for.
- Ground Sage: I have used ground thyme in its place in this recipe and it’s worked great.
- Chicken Broth: Beef broth or vegetable broth can be used here.
- Heavy Whipping Cream: Half-and-half or whole milk can be used.
- Shredded Parmesan Cheese: Grated Parmesan cheese can be used instead of shredded. You can also use shredded Asiago or Romano.
- Radishes: Cauliflower florets work really well in place of radishes here. If you use cauliflower, note that it will likely cook faster than radishes, so be sure to watch the soup closely so you don’t overcook the cauliflower. If carbs aren’t a concern of yours, you can use red potatoes here instead.
- Kale: Spinach can be used here, but note it will cook faster than the kale and it will change the resulting texture of the soup.
〰️ How to serve
- Alongside keto cheesy breadsticks or keto garlic bread rounds.
