Ingredients You’ll Need

Here’s everything you’ll need to bring this deliciously creamy Keto Tuscan Soup to life:

Italian sausage: Adds a punch of flavor and richness; opt for spicy if you like a little kick.
Garlic: Essential for building a deep, aromatic base—don’t skimp on it.
Onion: A small amount brings sweetness and depth without too many carbs.
Chicken broth: Forms the base of the soup—use a good quality, low-sodium broth.
Heavy cream: This makes the soup luscious and velvety. Coconut cream can be used if dairy-free.
Cream cheese: Helps thicken the broth and adds a touch of tangy richness.
Cauliflower florets: The perfect low-carb stand-in for potatoes, they soak up all the amazing flavor.
Kale: Brings a beautiful pop of green and a slight earthy bite—spinach is a good backup if kale isn’t your thing.
Parmesan cheese: For that final salty, nutty finish that rounds everything out.
Olive oil: Used to sauté the aromatics and sausage—choose extra virgin for best flavor.
Salt and pepper: To taste—be sure to season in layers as you go.

Variations

Add Bacon: A few crispy bacon bits tossed in at the end take this soup to the next level.
Swap the Greens: Not into kale? Baby spinach or Swiss chard are great alternatives and soften more quickly.
Make it Spicy: Use hot Italian sausage and add a pinch of red pepper flakes for serious heat.
Dairy-Free Option: Swap heavy cream with coconut milk and use dairy-free cream cheese or skip it altogether.
Vegetarian Version: Omit the sausage and load up on mushrooms, zucchini, or tofu for a meat-free twist.

How to Make Keto Tuscan Soup

Step 1: Brown the Sausage

In a large pot or Dutch oven, heat olive oil over medium heat. Add the Italian sausage and cook, breaking it up with a spoon, until browned and cooked through.

Step 2: Sauté Aromatics

Add chopped onion and minced garlic to the pot. Sauté until the onion is translucent and the garlic is fragrant, about 2-3 minutes.

Step 3: Add Broth and Cauliflower

Pour in the chicken broth and bring to a simmer. Add cauliflower florets and cook until just tender—about 8-10 minutes.

Step 4: Stir in Cream and Cheese

Reduce the heat to low. Stir in the heavy cream and cream cheese, mixing until fully melted and combined into the broth.

Step 5: Add Kale and Simmer

Toss in the chopped kale and simmer for another 5 minutes, or until wilted and tender.

Step 6: Season and Serve

Season with salt, pepper, and a sprinkle of grated Parmesan. Ladle into bowls and serve hot.

Pro Tips for Making the Recipe

Cut the Cauliflower Small: This helps it cook quickly and mimic the texture of potatoes even better.
Room Temperature Cream Cheese: It melts faster and more smoothly into the broth.
Don’t Overcook the Kale: Keep it just tender—overcooked kale can become bitter and mushy.
Make It Thicker: If you want a thicker soup, let it simmer uncovered for a few extra minutes after adding the cream cheese.

How to Serve

This Keto Tuscan Soup is a meal on its own, but here’s how to make it even more enjoyable:

Garnishes:

Top with extra Parmesan, red pepper flakes, or a drizzle of olive oil for a restaurant-style finish.

Side Dish Ideas:

Serve with a slice of keto garlic bread or a crisp Caesar salad for a truly satisfying low-carb dinner.

As an Appetizer:

Serve smaller portions before a main dish like grilled chicken or baked salmon.
