Ingredients & Substitutions

What is cream of chicken soup made of?
This recipe makes the equivalent of one can of store-bought condensed cream of chicken soup.
- sourdough starter & butter: Traditionally, cream of chicken soup is made with flour, but this is a great way to use up sourdough discard. The slight tang from the sourdough starter really amps up the flavor too. Butter and sourdough starter are what create the base of the roux which thickens the soup.
- chicken broth & milk: Milk adds creaminess and chicken broth gives it the chicken flavor. I highly suggest making your chicken broth for this recipe, but you can use store-bought chicken broth if that's what you have on hand.
- seasonings: Garlic powder, onion powder, celery seed, salt, and black pepper are used to season this soup.
- vegan and vegetarian options: Make this vegetarian and vegan by using plant-based butter, plant-based milk, water or vegetable broth, and a vegan chicken bouillon powder.
How to make condensed cream of chicken soup with sourdough starter

Step 1: Melt the butter.
Melt butter over medium heat in a saucepan.

Step 2: Add the seasonings and sourdough starter.
Add the seasonings and sourdough starter to the pan and whisk continuously until it thickens. This will take about 30-60 seconds.

Step 3: Add the broth and milk.
Whisk in the broth, a tablespoon at a time, to break up any lumps. Then add the milk.

Step 4: Thicken
Keep whisking continuously for 2-3 minutes until the soup thickens.

Pro Tip
To prevent lumps in the soup base, gradually add the broth a few tablespoons at a time to the thick butter and sourdough mixture while continuously whisking. This ensures a smooth and creamy consistency, perfect for your homemade cream of chicken soup.
How to Store
Fridge: Store the soup in a mason jar with a tight-fitting lid or airtight container and refrigerate for 5-7 days.
Freezing: We tested freezing this soup and thawing it out. The texture was a bit grainier as opposed to making it fresh, but it dissolved well when adding liquid to it to make it into a soup. You can still add it to recipes like casseroles, but the texture may be a bit grainier than freshly made.
Store in a mason jar with a tight fitting lid or airtight container and freeze for up to 1 month.
How to use
If you want to make a hearty cream of chicken soup, after you've made the condensed cream of chicken soup, add 3 cups of chicken broth to the saucepan and whisk until it is smooth with no lumps.

This will make 4 (1) cup servings. Serve right away topped with fresh chopped herbs such as parsley or thyme.

This soup base can be used for any recipe that calls for a can of condensed cream of chicken soup. Use it to make things like green bean casserole, hashbrown casserole, or chicken pot pie.

FAQs
Cream of chicken soup uses condensed cream of chicken soup as it's base. Additional liquid such as chicken broth is added to thin it out.
If your cream of chicken soup is too thin, make a slurry out of flour or cornstarch and water and add it to the soup. Bring the soup to a simmer and whisk until it has thickened.





I just made this and accidentally added the 3 cups for soup. Is there any way to get it back to condensed style? Thank you
