Slow Cooker Creamy Keto Tuscan Soup

One of my favorite things to eat when trying to stick to a gluten free, low carb diet is hearty, meaty low carb keto soups.

They are filling, don’t weigh you down, and great for leftovers you’ll look forward to tucking into the next day.

This family loved soup is like a large pot of heavenly goodness – and is really similar to a low carb zuppa toscana soup recipe.

If you love the famous Olive Garden soup, you’ll like this twist with roasted red peppers, and spinach instead of kale.

We also have a very low carb kale tuscan soup recipe you can check out here! It’s loaded with hearty creamy goodness from cream cheese and heavy cream – and is keto friendly for a delicious soup low carb dieters can enjoy.

While this recipe is easy to make and takes less than 30 minutes on the stovetop, it is also awesome as a set it and forget it keto slow cooker soup! 

For the best results, please follow my tips to making this creamy tuscan soup in the slow cooker. 

Tips to converting this creamy tuscan soup recipe for the crockpot:

  • Be sure to sauté the onion and garlic before adding to the slow cooker, since it helps to bring out the rich, caramelized flavor in this delicious low carb soup – and be sure to season vegetables as you brown them for the best flavor. 
  • Don’t add cream until the end of cooking, and whisk vigorously when adding in.
  • I also add cream cheese after soup has reduced significantly in the slow cooker, since adding it too early causes it to burn on the bottom of the pan. 

Instant Pot Keto Sausage Tuscan Soup Recipe

If you want to make this easy keto sausage soup in your Instant Pot, it is super simple to convert the recipe to use in a pressure cooker!

I often make our soup this way – it comes out delicious, with less to clean and less mess on the stovetop!

Simply follow these directions for a creamy sausage soup in your instant pot:

  • -Brown meat and vegetables in pan of Instant Pot, as directed in stovetop recipe. Do not add spinach, cream, or cream cheese (we will add them at the end for the best flavor and minimal separation!)
  • -Add stock and close lid to Instant Pot, seal.
  • -Select manual setting; adjust pressure to high, and set time for 4 minutes.
  • -When finished cooking, quick-release pressure according to manufacturer’s directions.
  • -Don’t add spinach, cream and cream cheese until the end of cooking after released – and be sure to whisk vigorously when adding in.

How can I keep the cream from breaking?

Turn heat off soup when adding cream and whisk vigorously when adding, before returning to heat, when adding cream to soup to keep cream from separating.

Should I drain oil from sausage?

Don’t drain fat from browning meat, as it will add flavor to vegetables. If you have a ton of oil in pan after sautéing vegetables, drain off some before adding stock.

  1. Looks wonderful. I’ll be using low-fat cream cheese and half + half instead of full fat, as I see no value added in the extra fat.

    1. Full fat has less carbohydrates and is better for you. When you buy low-fat products there are ingredients added to it that aren’t good for your body. Full fat is better. We need the fat and low carbs is the key.

  2. There appears to be cauliflower and bacon in the soup, also, but neither is listed in the ingredients. How much did you add? Any other veggies?

    1. Hey Marcy – the picture of the soup with Cauliflower and bacon is actually on my friend’s website – you can click the link under the photo to get her recipe! We made these soups to bring similar flavors with different ingredients 🙂
