Keto Zuppa Toscana Soup

Keto Zuppa Toscana Soup

Zuppa Toscana has been a long-time menu preferred at Olive Garden. The restaurant version features a creamy broth made with spicy Italian sausage, fresh kale, and russet potatoes. Unhappily, those potatoes make this soup off-limits for anyone eating keto. Just one bowl could be enough to potentially knock you out of ketosis!

Luckily, Olive Garden’s Zuppa Toscana recipe is simply adapted for a ketogenic diet. It’s an easy matter of swapping out those starchy potatoes for cauliflower! Today, we’re sharing our keto Toscana soup recipe, and it’s so flavorful, you won’t even miss the carbs – we promise!

It’s completely possible to adapt this recipe for the Crock-Pot! First, brown the meat with the onions and garlic, then place the browned ingredients inside the slow cooker along with the water, the broth, and the cauliflower. Cover and cook on HIGH for 4 hours or LOW for 6-8 hours. Stir in the kale and cream at the very end of your cooking time and serve hot. Easy-peasy!
