Ingredient substitutions for keto Italian sausage soup

  • Avocado Oil: You can substitute olive oil at a 1:1 ratio for avocado oil.
  • Mild Italian Sausage: Hot Italian sausage, ground turkey, or ground chicken can be used in place of mild Italian sausage
  • Chicken Broth: Vegetable broth or beef broth will work here. Sub in at a 1:1 ratio.
  • Heavy Whipping Cream: Combine 1/4 cup of melted butter with 3/4 cup of milk and mix thoroughly to make the equivalent of 1 cup of heavy cream. You can also use half-and-half at a 1:1 substitution ratio. If you are avoiding dairy, you can try substituting full-fat canned coconut milk at a 1:1 ratio for heavy cream, but I have not personally tested this; if you go this route, the flavor of the dish will be altered.
  • Shredded Parmesan Cheese: Shredded Pecorino Romano cheese would make an excellent alternative to Parmesan at a 1:1 ratio. You can also use grated Parmesan instead of shredded here.

Keep in mind any changes you make to this recipe will modify the total net carbs.

Recipe FAQs

Is there a way I can add some heat to this recipe?

Yes! If you like having a little spice to your food, try adding a chopped and de-seeded jalapeño to the soup. You can also add red pepper flakes and/or ground cayenne pepper. Personally, I add some chopped jalapeño almost every time I make this soup.

Can I use half-and-half in place of heavy whipping cream?

Yes, a 1:1 ratio of half and half may be used in place of heavy whipping cream in this recipe. Keep in mind that if you use half and half, the sauce will not be as thick or creamy as it would be with heavy whipping cream. This substitution will also result in a higher net carb content per serving for the soup.

How do I store keto sausage soup?

For maximum freshness, keep keto sausage soup in an airtight container for up to 3 days in the refrigerator. To reheat, heat the soup slowly on the stovetop so that the heavy cream does not separate. If you only want to reheat a single serving, cook it for 2 to 3 minutes in the microwave.

Can I freeze creamy Italian sausage soup?

I don’t recommend freezing this soup. Due to the heavy cream and cream cheese, it may break while in the freezer.
