    • Cauliflower – Cut into equal-sized florets for even cooking.
    • Olive Oil – You’ll coat the cauliflower in oil before roasting to help it achieve that crisp-tender texture and prevent it from burning.
    • Seasonings – We’re keeping it simple with a combination of salt, pepper, and garlic powder. 
    • Italian Sausage – Casings removed. I use mild Italian sausage, but feel free to use spicy if that’s what you prefer. 
    • Bacon – You’ll need 1 package of thick-cut bacon, chopped into equal-sized pieces.
    • Onion – I like to use sweet onion, but you can use white or yellow onion too if preferred.
    • Chicken Broth – Use your favorite variety! 
    • Heavy Cream – To add richness and creaminess to the soup.
    • Kale – Kale is a classic addition to zuppa toscana. It adds color and texture and soaks up the flavors in the broth perfectly.

    How to Make Keto Zuppa Toscana

    • Step One: Place the cauliflower florets onto a baking sheet, toss with olive oil, salt, pepper, and garlic powder, then roast at 375ºF in the oven until tender. 
    • Step Two: In a large skillet, cook the sausage until browned. Drain the fat and set aside. In a large pot, cook the bacon until crispy, then remove and set aside. Save the bacon drippings in the pot. 
    • Step Three: To the pot with the bacon drippings, add in the onions and sauté until softened. Season with salt, pepper, and garlic powder, then add in the chicken broth and cooked sausage. Cover and simmer over medium-low heat for 20 minutes, then mix in the roasted cauliflower, cooked bacon, and heavy cream. Cook for an additional 5 minutes.
    • Step Four: Turn the heat off, stir in the kale, then cover the pot again and let it sit for 20 minutes. Once the kale is wilted, portion into serving bowls, and dig in!

    What to Serve with Zuppa Toscana

    Zuppa toscana is a tasty and hearty meal as-is, but I do love to serve it alongside a number of different sides to round it out even more. Here are some favorites:

    Recipe Tips and Tricks

    • Drain the sausage fat. After the sausage is cooked, be sure to drain the excess grease before you add it to the soup. Otherwise, you’ll end up with oily soup!
    • Save the bacon drippings. You’ll use the bacon drippings to sauté the onion. It adds so much flavor!
    • If you plan to freeze the soup, I recommend leaving out the heavy cream, then adding that once it’s thawed and reheated. Frozen and thawed dairy can separate.

    Variations and Substitutions

    • Use other veggies. Swap the kale for spinach or add in other keto-friendly veggies. Try bell pepper, green beans, broccoli, diced celery, you name it.
    • Make it cheesy. Finish your soup off with a sprinkle of freshly-shaved parmesan cheese.
    • Spice it up. Love some extra heat? Add a sprinkle of red pepper flakes or cayenne to the soup.

    Storage Instructions

    Leftover zuppa toscana can be stored in an airtight container in the fridge for 3-4 days. Be sure to let it cool completely before transferring it to a container!

    To reheat, simply warm it on the stove until heated through! Keep the heat pretty low so as not to burn the soup.

    Can this be frozen?

    Yes! This soup can be frozen for up to 3 months. Simply let it cool completely, transfer it to a freezer-safe container, and store. 

    To enjoy again, let it thaw overnight in the fridge, then reheat on the stove.

    What is Zuppa Toscana Made Of?

    Traditional zuppa toscana is a soup that features kale, zucchini, potatoes, celery, carrot, onion, tomato, and cannellini beans. 

    This keto version incorporates many of the same ingredients, but features roasted cauliflower instead of potato to keep it consistent with the keto diet. 

    Is Zuppa Toscana the Same as Italian Wedding Soup?

    Yes! Zuppa Toscana and Italian wedding soup are two different terms to describe the same dish—a hearty, flavor-packed, rich and creamy stew!
