Low Carb Zuppa Toscana Soup

Even though we mostly eat a “regular” diet, I have been incorporating a few more low-carb choices into our menu rotation. It’s even better when I can take a family-favorite recipe and make a few tweaks to make it lower carb.

One of my favorite soup recipes is my Copycat Olive Garden Zuppa Toscana. I love that I can easily switch it up a bit and swap out the potatoes for a lower carb option like cauliflower. It’s just as delicious as the original!

Let me show you how easy it is to make …

How to make Low Carb Zuppa Toscana

  1. Brown and crumble sausage with red pepper flakes.

    In a large soup pot or Dutch oven, crumble and brown the Italian sausage with the red pepper flakes over medium-high heat, until the sausage is no longer pink. Drain and set aside.

Low Carb Zuppa Toscana: FAQs

➡️ What kind of Italian sausage do you recommend?

Use whatever kind of Italian sausage your family prefers – sweet, mild, or hot. Feel free to substitute Italian sausage links for the bulk sausage. Cut the links open, crumbling the sausage, and discard the casing.

➡️ Is this soup spicy?

I don’t think it is – but if you are sensitive to spicy foods, you can omit or reduce the amount of red pepper flakes. Additionally, if you like more heat, you can increase the amount of red pepper flakes.

➡️ How long does this soup last?

For best results, store it in a covered container in the refrigerator for up to 3-5 days.

➡️ Can I freeze this soup?

Yes! I like to save any leftovers for lunch! Be sure to put any leftovers in a freezer-safe container (I like individual serving containers!) and use it within 3 months.
