The Carb Problem with Traditional Zuppa Toscana
While the Olive Garden version of Zuppa Toscana is popular, its traditional ingredients, particularly potatoes and flour-based thickeners, make it unsuitable for low-carb or ketogenic diets. Potatoes contribute significant carbohydrates, and flour adds hidden carbs.
The good news is that the core flavors—spicy sausage, smoky bacon, and kale—are low in carbohydrates. By substituting high-carb components with low-carb alternatives and using heavy cream for a rich, keto-friendly base, you can create a satisfying low-carb version. This preserves the comfort food aspect while managing carbohydrate intake.
Low-Carb Swaps for Zuppa Toscana Ingredients
Modifying Zuppa Toscana for a low-carb diet involves strategic ingredient swaps:
- Potato Replacements: To replace the texture of potatoes, consider using cauliflower florets, peeled and cubed turnips, or radishes. These options become tender when cooked and absorb the soup's flavors effectively.
- Creamy Base: Achieve a creamy texture without flour by adding heavy whipping cream towards the end of cooking. This provides richness and thickness with low carbs.
- Greens: Kale is the traditional, low-carb choice. Spinach is another option but should be added at the end due to its faster wilting time.
- Thickeners: For extra thickness, a small amount of xanthan gum can be used sparingly. Alternatively, pureeing some cooked cauliflower into the broth can naturally thicken it.
How to Make Low-Carb Zuppa Toscana
Follow these steps to create a delicious low-carb Zuppa Toscana:
- Brown diced bacon in a large pot, then remove. Cook ground Italian sausage in the same pot, drain grease, and set aside with the bacon.
- Sauté diced onions until soft, then add minced garlic and cook briefly.
- Pour in chicken or bone broth and bring to a boil. Add your chosen low-carb vegetable substitute (like cauliflower) and simmer until tender.
- Return the sausage and most of the bacon to the pot. Stir in heavy cream and chopped kale or spinach, cooking until the greens wilt. Season to taste.
- Serve hot, garnished with remaining bacon and Parmesan cheese.
