Low Carb Zuppa Toscana Instant Pot and Stove Recipe

Make this low-carb, keto friendly copycat Zuppa Toscana Instant Pot recipe at home for a delicious dinner.

You will love how easy it is to make this recipe whether you use the stovetop, pressure cooker, or even a slow cooker!

This sausage kale soup has become one of my steadfast family recipes for years. If you’ve ever been to Olive Garden, then you know all about soup, salad, and breadsticks deal.

I love to order the Zuppa Toscana, which typically comes with potatoes. With a quick swap of frozen cauliflower for the potatoes, you have a low carb version that is loaded with flavor.

This is one of my family’s favorite soups year round and it’s so easy.

You can certainly make this with potatoes if you aren’t cutting carbs. In which case, I recommend following it with this tiramisu cake.

I never thought my kids would love kale, but they do! This Tuscan soup is a great way to get your greens. They also love this tomato tortellini soup loaded with spinach so if you ask me, we’re totally winning over here.

This is also a fabulous choice for low-carb days on the FASTer Way to Fat Loss plan too. It’s the most versatile soup ever.

What to Buy

This is one of my all-time favorite soup recipes and the ingredients are the same no matter how you decide to cook it.

I’ll add instructions for the Instant Pot first with variations on the stove or in a crockpot after that. It’s just as good all three ways, so use what is easiest for you.

Sausage-Kale-Soup-Ingredients

Shopping List/Ingredients:

  • Ground mild Italian sausage (we use mild but spicy sausage works too if that’s your thing). Note: if you are following Weight Watchers you can use chicken sausage in place of the Italian sausage.
  • Chicken Broth – vegetable broth would work too but since we already have meat and this isn’t a vegetarian soup, I tend to prefer chicken stock.
  • Heavy whipping cream – you can use half and half here but you will have a richer broth with cream. If you are following Weight Watchers, milk subbed for the heavy cream will lower your points. I’ve included it both ways in the recipe below.
  • Fresh Kale – I like recommend the full stalks and removing the leaves for the best texture. Bagged kale works too, but it’s not as leafy.
  • Frozen cauliflower – I have found that frozen cauliflower holds up the best in this soup. If you want to use fresh you can, but it may break down a bit faster.
  • Salt and pepper to taste
  • Red pepper flakes

Instant Pot Directions

You can make this soup with potatoes or cauliflower. Typically the Olive Garden version is made with russet potatoes, but it is a simple swap out with cauliflower to significantly lower the carb count.

In fact, my oldest never liked the potatoes anyway, so it’s an upgrade for him! The full sausage flavor and creamy broth are really what pulls it all together.

To make this recipe using an Instant Pot, first turn on the saute function and add a small amount of water.

Once the inner pan is hot, add the sausage and cook while stirring occasionally, and drain off any grease. For some reason, the sausage I buy doesn’t leave a lot of grease so I may or may not skip this step depending on how it looks after cooking.

Once the sausage is done and drained, turn off the pressure cooker and add the other ingredients.

Pour in the chicken broth first, then add the cream, kale, and cauliflower florets. Add spices last and give it a little stir.

Close the lid, set the vent to seal and then cook on “high pressure” for 5 minutes. It will take a few minutes to come to pressure before this clock starts counting.

Instant Pot Timer

When the timer is done, let it sit for about 5 to 10 minutes with the natural pressure release.

Then vent out whatever pressure is left by turning the vent to quick release before opening the lid.

Add to bowls to let cool and enjoy!

Optional Cooking Methods

If you don’t have or want to use a pressure cooker, you can make this soup on the stove or even in the slow cooker.

Personally, I love cooking this kale sausage soup right in the the soup pot. It makes clean up SO much easier.

If cooking on the stovetop, grab a soup pot and add a little bit of water, then cook the sausage and drain. Add the rest of the ingredients and bring to a boil.

Then lower the heat to low-medium and simmer for about 15 minutes.

To use the crockpot, cook the sausage first and add with all the ingredients to your slow cooker and set on low for about 2 hours.

This creamy soup probably shouldn’t sit all day in a slow cooker or you risk it getting too mushy.

Of all the green vegetables, one my kids have never complained about is kale. We love making kale chips in the oven and this soup is another winner.

Will they eat mac’n’cheese? Of course not. Don’t ask kids to make sense.

If cooking in the stove, how long would you say it needs to simmer after bringing to a boil?

Andrea Updyke

Monday 27th of January 2020

I would say a good 10-15 minutes should do it!

Is there a way to make this in the crock pot?

Andrea Updyke

Thursday 9th of January 2020

Sure! I would just brown the meat first and set it on low.

How many carbs did you calculate? One app said 9 which seemed high to me.

Andrea Updyke

Hi Lisa, so using the ingredients above with 6 servings, I'm getting 7net carbs. My guess is most of those are coming from the whipping cream. Your mileage may vary depending on the ingredients you use. Hope this helps!
