Italian Sausage KETO Soup Recipe:

This sausage spinach soup is a good choice for a keto diet recipe. As written this recipe contains only 10 net carbs.

That’s on the high side of the carb count for intentional Keto dieters. But this keto instant pot recipe still qualifies as KETO friendly. You may have to adjust the carbs to meet your personal goals.

I include some ideas to bring the carb count down even further in the ingredient section below.

Ingredients and Substitutions:

For KETO dieters it all about staying in Ketosis. To learn more about what that means check out this article on the signs of ketosis to make sure you truly attain your goals.

Sun Dried Tomatoes And Jar On A Paper Towel. Keto Soup Recipe
Flavorful sun dried tomatoes make sweet pops of flavor in this soup.

Sun Dried Tomatoes:

If you need to get your daily carb total down further and you need to cut the carbs even more… eliminate the sun dried tomatoes. That brings the total net carbs down to 9 carbs per serving.

However, those wonderfully sweet marinated dried tomatoes add a LOT of flavor to this low carb soup recipe. (I make my own and show you how in my homemade Sun Dried tomatoes post).

That delicious extra tomato carb is worth it in my opinion. But if you really need to bring the net carb count per serving to 10…chuck em.

Dicing An Onion For Tuscan Soup
Choose a yellow or white onion to add more flavor to this Tuscan soup.


For our KETO dieters onions are a bit problematic. They are on the higher carbs veggie list.

You can further reduce the carbs in this soup by one carb per serving by simple removing the onion from this recipe. Or cut it in half.

If you do that you make want to make a hot sausage choice to keep the flavors interesting.

Italian Sausage:

  • Try a hot spicy sausage rather than the mild if you prefer. The extra spice is welcome and satisfying if you are not feeding young children or bland eaters.
  • Have extra bacon laying around? You can add up to 8 slices of bacon to the pot when you sauté the sausage for even more fat and flavor.
Tuscan Keto Soup Recipe
pre washed baby spinach make this a really easy soup to assemble.

The Spinach:

We chose pre washed baby spinach to keep this beautiful soup really quick and easy. Washing spinach bunches can become a lengthy tiresome process.

Also if you are choosing a mature spinach leaf it will have to be cut to make it manageable on a spoon.

Eliminate all the bother by purchasing a pre washed baby spinach. Tender and small. Just dump several handfuls in the soup pot. Much easier and so tasty.

Kale for spinach:

Kale is a nutritious substitute for spinach. If you have it on hand it’s a great choice for this keto friendly recipe.

I LOVE kale in my homemade Lentil Soup with sausage.

  • Soup with kale is very nutritious and kale holds up well under heat.
  • You can cook this soup under pressure with the kale in it. I would not do that to spinach.
  • With kale you can also make this on your slow cooker function and let it simmer all day. Kale will hold up to that just fine.

Low Carb Tuscan Soup-The Process:

Here is a quick visual guide to this recipe. Please also watch our video for a complete demonstration of this recipe.

Ingredients For This Keto Soup Recipe
These three ingredients go into the soup after you pressure release the instant pot.

For best results in this recipe hold the cream, cheese and spinach back until after your instant pot is quick released. Then stir them in and serve.

The Instant Pot:

We used the 8 quart instant pot Ultra (linked below) for this soup recipe. A six quart instant pot will also work but be careful not to fill the stainless pot over the fill line or your pot won’t want to come to pressure.

Any brand electric pressure cooker or type of 6 quart or larger instant pot can be used to make this recipe. Just follow your manual instructions and use high pressure for five minutes.

Can this be done just in a pot on the stove?


Saturday 6th of November 2021

Hi Michelle, absolutely you can make this on the stove top instead of the instant pot. Do the Sauté in a fry pan on medium low heat. And then prepare the ingredients and add them to your soup pot. Bring to a boil and then reduce heat to simmer. Simmer covered about 20 minutes or until you like it. Hope this helps!

How do you convert your tuscan spinach keto soup into a crock pot recipe? I don't have an instapot. Your recipes are interesting and I would love to get started using them. Thanks!! Cathy


Monday 17th of August 2020

Hi Cathy, Welcome to Homemade Food Junkie. To convert this recipe from Instant pot to crock pot here is what you do: -Follow the instructions to brown in your skillet (or crock pot if it browns) up to instruction number six. -Now put all the browned ingredients in your crockpot and add the tomatoes, chicken stock and seasonings. -Set the crockpot to low heat for 4 hours. -Stir in the remaining ingredients just prior to serving. You want the spinach to wilt. Not cook. The dairy and cheese are also best served fresh. Please let us know how this works out for you. Have a great day!

Love your beginner's sourdough, I've been playing with it weekly for four weeks now! I'm ready to get adventurous beyond my flour and want to try to make a cottage cheese dill bread like what I use to get from Tassajara Bakery in San Francisco but all the recipes I find are with packaged yeast. I'd love to try to adapt this one. What would be your suggestion? Would I use the cottage cheese at the start instead of the water with my starter and then just fold the dill (and onion) in after the autolyse stage?




Sunday 2nd of February 2020

Hi Leslie, I'm so happy the beginner sourdough recipe is working out so well for you.:) You intrigue me with your idea for a cottage cheese dill bread recipe. I have never made a cottage cheese bread so I can't help you. However, I found this sourdough cottage cheese recipe from It uses the cottage cheese, dill and onion and the crumb looks pretty close to what I think you are shooting for. It does use different flours so I recommend reading the recipe and playing around with the ingredients to see if you can strike a balance that please you. AND THEN TELL ME. :) I'd love to know what you come up with. Thanks for the question. I hope this helps. Happy Baking!
