This creamy vegetable and whey soup is an easy and delicious way to use up extra whey. Warm and comforting, it is as perfect as a cup of soup for lunch or served with bread and a salad for dinner.
Don’t waste the whey
It is a huge waste to pour whey down the drain. Whey is healthy and delicious, which is why I have so many recipes that use whey.
This creamy whey soup is one that I enjoy every time I make cheese.
Many Types of vegetable soup
This basic cream of vegetable soup can be made with all different types of vegetables.
Here are a few of my favorite flavor combinations:
- Irish Vegetable Soup: Finely dice the onion, garlic, and potatoes. Add in 2 diced carrots and 2 cups of shredded cabbage. Follow the recipe, sauteing all the vegetables before adding the broth. Leave the vegetables chunky and serve with buttered brown soda bread.
- Cream of Broccoli Soup: Use 2 cups of chopped broccoli for the vegetables. You can even use the stems, just peel off the woody bits. Remove a few whole florets before pureeing, then stir the florets back in and top with grated Parmesan cheese.
- Cream of Mushroom Soup: Slice 3 cups of mushrooms. Saute until they release their juices, then add in the onion, garlic, and potatoes. Fry for 5 more minutes and finish the soup according to the recipe.
- Lemon and Asparagus Soup: This is ideal for using up acid whey. Trim and chop 1 bunch of asparagus. Add it to the soup when you add the broth. Finish the soup with the zest of 1 lemon. The acidity of the whey will replace the usual lemon juice. Top each bowl with grated Parmesan cheese.
- Baked Potato Soup: Instead of adding 2 cups of vegetables, use a total of 4 potatoes. Otherwise, follow the recipe as directed, then top each bowl of soup with a spoonful of sour cream, finely chopped chives, and grated cheddar cheese.
- Vichyssoise: Whey adds a bit of zest to this classic soup. Don’t add any garlic, and use 6 medium leeks for the vegetables. Wash the leeks carefully, then chop and saute with the potatoes. Follow the rest of the recipe as directed, and serve hot or cold.

- Prep Time: 10 minutes
- Cook Time: 20 minutes
- Total Time: 30 minutes
- Yield: 4–6 Servings 1x
- Category: Soup
- Diet: Vegetarian
- 2 Tbsp extra-virgin olive oil
- 1 onion, roughly chopped
- 2 cups of vegetables, roughly chopped (see above for options)
- 2 large potatoes, diced
- 3 cloves garlic, minced
- 3 cups of broth
- 2 cups of sweet whey (or water, see notes)
- 1 tsp salt, to taste
- 1/2 tsp ground black pepper, to taste
- 1/2 cup of heavy cream
- Saute the onions in the olive oil at the bottom of a large soup pot. After 5 minutes add in the garlic, potatoes, and vegetables, and saute for another 5 minutes.
- Pour in the broth and bring to a simmer. Simmer until the vegetables are soft, about 20 minutes.
- Add in the whey, seasonings, and cream, then puree until smooth. I usually remove a few of the signature vegetables and add them back after pureeing. It’s nice to have a few slices of mushroom or a broccoli floret in your soup bowl.
- If you need to reheat the soup at this point, do it carefully. You don’t want to simmer or the whey will curdle.
- Serve with some grated cheese and sourdough bread.
- Acidic whey (from an acid-curded cheese) will be quite sour. Even the 2 cups of sweet whey (from cultured cheese) can be quite strong in this soup. Sweet whey becomes more acidic as it ages, so start with just 1 cup of whey, and taste it before adding a second cup. The whey can be replaced with water as required.
- I like soups that have added protein so they become part of a complete meal. To add protein to this soup, replace the potatoes with 2 cups of cooked white beans or 1 cup of almond flour.
- I use an immersion blender to puree the vegetables; however, you could use a regular blender or just leave the vegetables whole.
