Keto Italian Sausage Soup Tips

This is a super-simple soup that you can make even when you are busy or rushed. These tips will help it turn out perfectly every single time.

  • Shred parmesan cheese at home. Not only will it taste better, but you won’t have to worry about extra anti-caking ingredients they add to packaged shredded cheese.
  • Use full-fat cream cheese. It’s best for your low-carb diet and keeps you Thin-Adapted. If you can’t find cream cheese, use Neufchâtel cheese instead.
  • Use spicy or hot Italian sausage to give this soup some kick.
  • Store leftovers in an airtight container in the refrigerator for up to three days. The creamy sauce will solidify in the refrigerator. Heat it up and it will melt again.

    This soup tastes SO yummy. I used to love the italian wedding soup at Olive Garden, and this soup reminds me of that a little bit- except WAYYY better! It’s so satistfying and filling, and it will definitely be a staple of our winter cooking this year!!

  2. This soup is delicious and comes together easily. I’ve made it twice now and it will be in regular rotation!

  3. 5 stars

    This was really good! I had 2lbs of ground pork, so added seasonings to make it sausage and doubled the recipe, kept my fingers crossed that it would be a hit with Hubby, since I was making so much. It was! It was easy to make, too! We eat light for supper, so this worked out really well. We will enjoy leftovers!
