We have all been to Olive Garden! Most of us have enjoyed the Zuppa Toscana Soup. It’s a savory soup made with sausage, potatoes, and kale. They will even shave fresh parmesan on top while you watch. It’s definitely a soup for the books!

This recipe is identical to my Instant Pot Zuppa Toscana Soup, but with a couple of tweaks.

Is Olive Garden keto friendly? Potatoes mean carbs! There is a way to make this dish no carb.

What to Use For Potatoes in Keto Zuppa Toscana

Sometimes the easiest swaps make a world of difference. Instead of using potatoes in this soup cauliflower is used instead. Cauliflower goes a long way with keeping a recipe ketogenic.

When cooked, cauliflower has a texture that is very similar to potatoes. Check out my Keto Cauliflower Mash if you haven’t!

Do You Have to Use a Dutch Oven

I use a Dutch oven because it allows me to use one pot for the recipe and it’s great for cooking soups. I brown the sausage and bacon and then throw the remaining ingredients into the pot and cook the soup.

Dutch ovens are heavy and thick. A Dutch oven conducts and retains heat really well and will keep the soup warm. You can read more about Dutch Oven Benefits here.

You can use whatever soup pot you want in the recipe.

How Many Calories and Carbs are in Zuppa Toscana?

How Long Will the Soup Last in the Fridge?

The soup can be refrigerated for 3-4 days.

Is the Soup Freezer Friendly?

Absolutely! The soup will freeze up to 3 months. Thaw in the fridge overnight and reheat the soup over the stove.

Sometimes, when I freeze soup with dairy, the dairy will separate from the soup (especially the longer you freeze). If you know you are planning to freeze in advance, I recommend adding the cream and kale to the soup after you have frozen it, as opposed to adding it when you cook the original batch.

Calories 309kcal

Ingredients

  • 1 pound ground sausage Italian Sausage works best (I used mild)
  • 3 slices bacon, sliced into smaller bits
  • 1 cup onion chopped
  • 3 garlic cloves, chopped
  • 1 head fresh cauliflower, chopped
  • 5 cups low-sodium chicken broth
  • 1 tsp dried oregano
  • salt and pepper to taste I like to season it at the end so that I can taste repeatedly and adjust as necessary.
  • 1 cup heavy whipping cream
  • 3 cups fresh kale, stems removed
  • parmesan for topping optional

Instructions

  • Add the pieces of bacon and sausage to a large pot (Dutch oven works best) on medium-high heat.
  • Cook until the sausage and bacon have browned. Drain any excess fat, but reserve about a couple of tablespoons of fat in the pot for flavor. (I didn't have to drain any fat.)
  • Add in the chopped onion and cook for 2-3 minutes until the onions are translucent.
  • Add the garlic, chicken broth, fresh cauliflower, oregano. Stir to combine.
  • Cover the pot and reduce the heat to medium. Cook for 15 minutes or until the cauliflower is soft and can be pierced with a fork.
  • Uncover the pot and add the heavy cream, chopped kale, salt and pepper to taste.
  • Cook for a couple of minutes until the kale wilts.
  • Cool before serving.

Notes

  • For me a Dutch oven yields the best results. You can use whatever soup pot you want in the recipe.
  • You can use 1/2 cup heavy cream to reduce calories in this recipe.
  • You can add 1/2 tablespoon of Italian Seasoning to standard ground sausage if you choose not to use Italian sausage.
  • I like a lot of kale in my soup (it’s loaded with fiber) you can adjust to your taste.
  • Sometimes, when I freeze soup with dairy, the dairy will separate from the soup (especially the longer you freeze). If you know you are planning to freeze in advance, I recommend adding the cream and kale to the soup after you have frozen it, as opposed to adding it when you cook the original batch.

I can't tell you enough about how much the meat eaters in my family LOVE this soup. In the fall and winter I make it at least once a week or every other week. Mondays are soup days and this one gets HEAVY rotation. My boys LOVE it. I make double and triple batches because I've got two boys in the home, ages 17 and 21 and they EAT A LOT and... it's even better the next day. Thank you for such an easy, simple yet delicious go to meal. The other cool thing is I often don't have to plan it because these ingredients are staples in my kitchen. So simple that even the boys have made it when I've been gone. Good stuff. Thanks!!

The flavors in this soup owns me nothing…well the entire soup doesn’t owe me anything! This was DELICIOUS. I couldn’t even tell that it was used with cauliflower and not potatoes.

This recipe is divine — flavorful, quick and easy to make! I had all the ingredients on hand and was able to make it during my lunch break with time to spare. I love soup and this one is definitely going in my regular rotation. I subbed the heavy cream for a dairy free one due to allergies but other than that I made no modifications to the recipe.
